Degrees of forgery

Judges don't always agree that a given statutory text coincides with its purpose. In Li v R [2008] NZSC 114 (19 December 2008) the majority of four judges held that text and purpose coincided, while the Chief Justice dissented. The text was s 256(1) of the Crimes Act 1961[NZ], which defines an offence of forgery:

"Every one is liable to imprisonment for a term not exceeding 10 years who makes a false document with the intention of using it to obtain any property, privilege, service, pecuniary advantage, benefit, or valuable consideration."

Here the appellant had been convicted on counts of making false certificates of qualifications and selling them to people who knew they were false documents.

The majority held that this wording was clear and that there was no need for an intent to deceive the person who provides the payment. This places on an equal footing, as far as maximum penalty is concerned, those who make a false document intending to obtain valuable consideration with those who use such a document to obtain such consideration (s 257(1)(a)). The act of selling the false document to a knowing recipient is a making use of the falsity of the document if the seller knows that it will be used deceptively (69). This contrasts with an innocent copying, of a famous picture for example, where the maker believes the purchaser has no intention of using it deceptively (joint judgment at 67, and Elias CJ at 53).

How could anything be more simple, you might wonder. On what basis could the Chief Justice dissent?

She found (4) it difficult to construe the section – a sure sign, I suggest, that something is about to go wrong. She didn't like the idea that this serious offence could be committed without deceiving the purchaser of the false document. The majority at 52-53 explain why that is not a bad thing.

Central to Elias CJ's approach is a perception of reduced culpability on the part of those who do not deceive their purchasers (30, 41), but the joint judgment sees no such distinction (53). Elias CJ considers that on the majority's approach it was sufficient for the judge to direct the jury that an intention to sell the document to a person who was not deceived would be sufficient for liability (39), but that is not the entirety of the majority's conclusion (69) which recognises that the judge's direction may technically have been incomplete in its omission of a need for proof that the accused intended the purchaser to use the document deceptively.

The appellant had made a concession (apparently in pleadings, not mentioned in argument) that destroyed her opportunity for a retrial. She had acknowledged that she should have been convicted of a lesser offence (s 256(2)). However, as the majority pointed out, that acknowledgement cured any defect in the judge's direction (69) and her appeal was dismissed.

Kingdom or country?

For discussion of when time begins to run in relation to the right to be tried within a reasonable time, see Burns v HM Advocate [2008] UKPC 63 (15 December 2008). The fact that a decision is made to hold the trial in another country (here, Scotland) does not mean that time runs from when proceedings are initiated in that country if the accused person has previously been told by officials in one country (here, England) he will be charged.

Given that time ran from when the appellant was first informed he would be charged, the question of whether the delay was unreasonable and if so what was the appropriate remedy was left to be decided after the trial, applying Spiers v Ruddy [2007] UKPC D2.

It was appropriate to view the events as a continuum (Lord Rodger at 24) and to look at substance rather than form (Lady Cosgrove at 52). Delay is to be assessed from the defendant's perspective (26, 46). Ordinary people will be unaware of jurisdictional subtleties (54) and the obligations under the Convention are incurred by the United Kingdom; the governing consideration is not how the UK arranges its internal jurisdictional matters (27).

On when a person is charged, Lord Bingham's dicta in Attorney General's Reference (No 2 of 2001) [2003] UKHL 68; [2004] 2 AC 72, 91, paras 27-28 were applied (15). All the circumstances must be considered, but

"As a general rule, the relevant period will begin at the earliest time at which a person is officially alerted to the likelihood of criminal proceedings against him."

The implications of deeming

What are the implications of the phrase "A discharge under this section shall be deemed to be an acquittal": s 347(4) Crimes Act 1961[NZ]?

Does it imply that there should be deemed to have been a verdict of not guilty? And that evidence had been adduced that was sufficient for a fact finder (jury usually) to consider? And that the evidence that the prosecution had adduced at this notional trial had been the strongest that had been anticipated on the basis of pre-trial proceedings?

Or does it simply mean that when the judge told the accused "You are discharged" he meant "You are found not guilty without the need for a trial"?

A difference in understanding of the meaning of "deemed" in this context, where its implications for the special plea of previous acquittal (s 358(1)) had to be determined, was the basis for a difference of opinion in the New Zealand Court of Appeal: R v Taylor [2008] NZCA 558 (17 December 2008).

The majority (Chambers and Panckhurst JJ) in separate judgments placed slightly different emphasis on grounds for their conclusion that where s 358(1) mentions a "former trial" it means an actual trial, not a notional trial that was deemed by s 347(4) to have occurred.

Chambers J at 39 set out his reasons for declining to give "former trial" an expansive meaning. Each of these may, with respect, be challenged. He said an expansive meaning would strain the wording of the subsection, that he didn't know how the subsection should be re-written, that the same expanded meaning would have to apply in s 358(2) and 359(3), so that and revision of the law would have to be legislative. In answer to those propositions it could be said that there is no straining other than that required by the deeming provision, that no rewriting is required, and that the phrase "former trial" need not have the same meaning every time it is used but can take its meaning from its context.

Panckhurst J focused on the common law origins of the legislative provisions on the special pleas, holding (116) that there is an underlying requirement of jeopardy of conviction. Consequently, "former trial" means an occasion on which the accused was at risk of conviction (117), and that a deemed acquittal does not trump the requirement of actual jeopardy (123).

That, of course, assumes that the legislature did not intend to deem a former trial to have occurred.

Fogarty J dissented on this point. He held (134 – 138) that the deeming provision should not be read down, but instead should be given a liberal interpretation so as to mean that there was deemed to have been a trial prior to the proceedings at which the special plea is made. Parliament intended that a discharge under s 347 should carry all the benefits of an acquittal (139). This removes any apparent inconsistency between the sections (141).

There are attractions in the reasoning of the dissent. An interpretation that avoids legislative inconsistency is preferable to one that requires the legislators who enacted the Crimes Act 1961 to be thought of as fools whose efforts were "curious and archaic" (25).

No doubt the unsuccessful (self-represented) appellant will be drafting his application for leave to appeal to the Supreme Court. On the assumption that these proceedings are not yet at an end, I say no more.

[Update: the Supreme Court refused leave to appeal: Taylor v R [2009] NZSC 45 (15 May 2009), saying that "whatever may be the answer to the s 347 point" the proposed appeal had no prospect of success because the offences were not sufficiently similar to permit the plea of previous acquittal on the facts.]

Don’t mention rights ...

Just a note on reverse onus provisions and when the legal burden is appropriate instead of merely an evidential burden: R v Chargot Ltd (t/a Contract Services) [2008] UKHL 73 (10 December 2008).

Lord Hope, with whom the other Law Lords agreed, said at 28:

"Section 40 [of the Health and Safety at Work etc Act 1974] imposes a reverse burden of proof on the employer. In Sheldrake v Director of Public Prosecutions [2004] UKHL 43; [2005] 1 AC 264, para 21 Lord Bingham of Cornhill said that the justifiability of any infringement of the presumption of any innocence cannot be resolved by any rule of thumb, but on examination of all the facts and circumstances of the particular provision as applied in the particular case. In para 30 he drew attention to the difference between the subject matter in R v Lambert [2001] UKHL 37; [2002] 2 AC 545 on the one hand, where it was held that the imposition of a legal burden on the defendant undermined the presumption of innocence, and R v Johnstone [2003] UKHL 28; [2003] 1 WLR 1736 on the other, where it was held that there were compelling reasons why there should be a legal burden. In the former case, where section 28 of the Misuse of Drugs Act 1971 was in issue, a defendant might be entirely ignorant of what he was carrying. In the latter, offences under section 92 of the Trade Marks Act 1994 are committed by dealers, traders and market operators who could reasonably be expected to exercise some care about the provenance of goods in which they deal. It seems to me that the situation in which the reverse burden imposed by section 40 arises is analogous to that in R v Johnstone. Sections 2 and 3 impose duties on employers who may reasonably be expected to accept the general principles on which those sections are based and to have the means of fulfilling that responsibility."

This direct – almost casual – approach to deciding the appropriate standard on reverse onus is refreshing in comparison to the intricate exercise that bills of rights seem to require, culminating in a balancing of rights to see if there is an infringement and, if there is, a determination of what limitations are justified in a free and democratic society.

Absolute or relative inhumanity

As recently as 18 March 1789 Catherine Murphy was burnt at the stake at Newgate, although locals regarded this event distastefully. Her death did not attract a crowd like that of the 20,000 who witnessed the burning of Elizabeth Herring at Tyburn on 13 September 1773. The method of Catherine's execution (for clipping coins) shows traces of humanity:

"Catherine Murphy's execution was to be the last burning of a woman in England and was really was only a modified form of hanging, followed by burning. She was led from the Debtor's Door of Newgate past the nearby gallows from which 4 men, including her husband, were already hanging, to the stake. Here she mounted a small platform in front of it and an iron band was put round her body. The noose, dangling from an iron bracket projecting from the top of the stake, was tightened around her neck. When the preparations were complete, William Brunskill, the hangman, removed the platform leaving her suspended and only after 30 minutes were the faggots placed around her and lit."

Is inhuman or degrading punishment a relative, or an absolute, concept? What seems fine to us might be abhorrent in another culture. Or, putting it the other way, should we condemn as inhuman the practices of another culture merely because we would call them so?

There must be many people in cultures not dissimilar to the English who approve of the death penalty. Examples of executions by lethal injection may be cited as illustrations of humanity, not unlike the act of kindness that pet owners may have to authorise. Far more terrible may, in the minds of such people, be the locking of a person in a cage-like cell for the rest of his life, perhaps several decades. Even opponents of the death penalty may not protest very loudly when those who commit hideous crimes are executed in jurisdictions where that is lawful. Absolute opposition may, in such cases, tend to be softened by relativist views.

In R (on the Application of Wellington) v Secretary of State for the Home Department [2008] UKHL 72 (10 December 2008) the issue was whether extradition of the applicant to Missouri, where he was wanted for trial for two murders, would breach article 3 of the ECHR, the right not to be subjected to inhuman or degrading punishment, where if convicted he would be sentenced to life imprisonment without the possibility of release.

Three of the judges were relativists: Lord Hoffmann (para 27), Baroness Hale (48) and Lord Carswell (57). The absolutists were Lord Scott (40) and Lord Brown (86).

The relativist approach does not simply adopt as legitimate the punishments that are lawful in the foreign jurisdiction. There would be a breach of article 3 if extradition would give rise to a real risk of a punishment that "shocked the conscience" (Lord Hoffmann at 32, citing Ferras v United States) or would be clearly or grossly or obviously disproportionate (35 - 36). The point about relativism is that what might seem unacceptable in the UK may nevertheless be acceptable in the context of the foreign culture. The example cited was the prison practice of "slopping out" – making prisoners empty their own chamber pots: this had been held, by the Court of Session, to be inhuman in Scotland, whereas Lord Hoffmann pointed out that it might be normal in countries "where people who are not in prison often have to make do without flush lavatories" (27).

Underlying the relativist approach is the policy of preventing those accused of serious crimes from obtaining a refuge from justice – by resisting extradition – simply because their crimes deserved severe punishment. Baroness Hale (at 50, 51) referred to para 89 and 100 of Soering v United Kingdom (1989) 11 EHRR 439 in support of the view that all the circumstances of the particular case must be assessed in evaluating whether a likely punishment would be inhumane because the penalty must be relative, or proportionate, to the offence. Concluding that here extradition would not breach of article 3, she added (53):

"There are many justifications for subjecting a wrongdoer to a life in prison. It is not for us to impose a particular philosophy of punishment upon other countries."

Lord Carswell, the third relativist, also cited para 89 of Soering. He drew the following from Strasbourg jurisprudence (58):

"It has been held in Chahal and in Saadi v Italy (2008, Application no 37201/06, BAILII: [2008] ECHR 179 ) that the risks to the expelling state if such a person is not deported cannot be weighed against the risk of his ill-treatment in the receiving state: Saadi, para 138. If it is established that that ill-treatment would amount to torture or inhuman or degrading treatment, the prohibition is absolute: ibid, para 127. The passage which I have quoted from the judgment in Soering demonstrates that in extradition cases considerations founded upon the importance of extradition may legitimately be taken into account in determining whether the alleged offender's treatment would attain the minimum level of severity which would constitute inhuman or degrading treatment, an assessment which is relative: Saadi, para 134."

Saadi is blogged here: see entry for 25 July 2008.

I'm not sure that Lord Carswell is clarifying the point by citation of Saadi. One of the justifications for a severe sentence may be the need to protect society. The need to protect the UK cannot be a justification for concluding that the likely foreign sentence would not be inhuman: Saadi. It is the need to protect the foreign society that may justify the sentence likely to be imposed by that society. But the offender is resisting efforts to return him to that society. There may be cases where that reasoning makes sense (he might pose a risk to the foreign society from his base in the UK) but that was not the situation here. Any risk posed by the appellant to the UK was irrelevant to whether his sentence in Missouri would be inhumane, and while in the UK he posed no risk to Missouri.

Be that as it may, the relativist position can be summarised as, up to the point where we would regard a foreign sentence as unconscionable, what might be regarded as inhuman here may not be inhuman over there. It helps in understanding this to keep in mind the "slopping out" example. The weakness in the relativist position is shown by Lord Hoffmann's indication that he is not necessarily convinced that the "slopping out" illustration is a good one (27): "Whether, even in a domestic context, this attains the necessary level of severity is a point on which I would wish to reserve my opinion."

The trouble is that once you find an example of something that really would be inhuman treatment in the domestic jurisdiction, you should say it would be inhuman anywhere. This is the absolutist position of Lords Scott and Brown. Indeed, Lord Brown says this very thing at 88. The absolute position does have some awkwardness, because it purports not to impose Convention standards on other countries (86). Lord Scott seeks to avoid the difficulty by suggesting, at 42, that article 3 prescribes minimum standards, not norms, so that while "slopping out" may be below the norms acceptable in Scotland, that does not mean it is a breach of article 3.

All judges agreed that the likely punishment in Missouri was not inhuman and that in the circumstances of this case extradition would not involve a breach of article 3 of the Convention.

Strange to say, the Law Lords did not refer to their decision in R v Secretary of State for the Home Department, ex p Adam, blogged here 7 November 2005, in which the same right was held to be absolute.

DNA record retention

Retention by the police of information about a suspect can be a breach of the suspect's right to privacy: S and Marper v United Kingdom [2008] ECHR 1581 (4 December 2008).

This case concerns fingerprints and DNA samples taken by the police. Neither of the applicants was convicted and both requested destruction of these records. The police refused.

The Grand Chamber held that retention of the information in such circumstances was a breach of the applicants' rights to privacy and that vindication was achieved by the Court's finding of a violation in view of the resulting obligation on the UK to secure the rights of the applicants and of persons in their position.

This decision applies to samples taken directly from suspects. That sort of information collection is now the subject of legislation in many jurisdictions. In New Zealand we have the Criminal Investigations (Bodily Samples) Act 1995. The bracketed words highlight its focus which is the obtaining of invasive intimate samples, if necessary by force; it does not provide a code for the obtaining of such information by other non-invasive means: R v Cooper CA381/00, 19/2/01. DNA from clothing seized during execution of a search warrant was used in that case to establish that the accused was the father of the victim and of her child. The Court of Appeal held that this investigatory technique was not unreasonable, and also that it was lawful, meaning that the Act did not apply to this means of gathering information.

There is in NZ no regulatory regime governing the retention and destruction of information obtained by indirect means such as those used in Cooper. Obviously, where the suspect is convicted, permanent retention of the information may be justified, as it is under the Act for convictions of specified offences. But for people like the applicants in S and Marper, more rules are needed.

Discuss: no case or no chance?

When should a judge prevent a prosecution case from continuing and discharge the accused for lack of evidence?

The "no case" submission was addressed in DPP v Varlack [2008] UKPC 56 (1 December 2008). This was a case in which the prosecution had relied on inferences, rather than on direct evidence of involvement in a murder.

There is potential in this subject for confusion of a number of threads. One thread is what the judge must decide in ruling on a no case submission. Another is how the jury must be directed on inferences. Another is how an appellate court decides whether an error may have deprived the accused of a real chance of a more favourable verdict.

In Varlack the Privy Council endorsed a statement of the law by King CJ in Questions of Law Reserved on Acquittal (No 2 of 1993) (1993) 61 SASR 1, 5, which included the following:

"It is not [the judge's] concern that any verdict of guilty might be set aside by the Court of Criminal Appeal as unsafe. Neither is it any part of his function to decide whether any possible hypotheses consistent with innocence are reasonably open on the evidence ... ."

So, never mind how the jury will be directed about inferences of innocence, and never mind about how an appellate court will view a conviction. It is beside the point on a no case submission that the judge will tell the jury that they cannot convict if they think there is a reasonable inference that prevents an essential element of the prosecution case from being established to the necessary standard.

But it is relevant on a no case submission that the judge considers that the evidence on an element of the offence is so inherently weak or vague that a reasonable jury properly directed could not convict. It is only in that class of case, where the evidence is tenuous, that the judge's assessment of the acceptability of the prosecution evidence is relevant to the no case issue.

That is because questions of fact are for the tribunal of fact. On a no case submission, if the evidence is not inherently weak or vague, the judge has to decide whether the evidence is adequate. Adequacy is a question of law. It does not require anticipating what the jury will decide. A case is adequate, in this sense of overcoming a no case submission if, to quote the "canonical statement of the law" by Lord Lane CJ in R v Galbraith [1981] 1 WLR 1039, 1042 cited in Varlack at 21:

"... a reasonable jury properly directed could on that evidence find the charge in question proved beyond reasonable doubt."

King CJ elaborated, in the passage quoted by the Privy Council at 22 of Varlack:

"I would re-state the principles, in summary form, as follows. If there is direct evidence which is capable of proving the charge, there is a case to answer no matter how weak or tenuous the judge might consider such evidence to be. If the case depends upon circumstantial evidence, and that evidence, if accepted, is capable of producing in a reasonable mind a conclusion of guilt beyond reasonable doubt and thus is capable of causing a reasonable mind to exclude any competing hypotheses as unreasonable, there is a case to answer. There is no case to answer only if the evidence is not capable in law of supporting a conviction. In a circumstantial case that implies that even if all the evidence for the prosecution were accepted and all inferences most favourable to the prosecution which are reasonably open were drawn, a reasonable mind could not reach a conclusion of guilt beyond reasonable doubt, or to put it another way, could not exclude all hypotheses consistent with innocence, as not reasonably open on the evidence."

So, as the Board put it at para 23, the test is what inferences a reasonable jury properly directed might draw, as distinct from what inferences the judge (or the Court of Appeal) thought could or could not be drawn.

You may think that here there are moments of clarity, rapidly followed by periods of obscurity. The point to remember is that the facts are for the jury to determine except in cases where the evidence is inherently weak or vague.

The position was summarised in R v Harder 29/5/03, Williams J, HC Auckland T002481:

"A conviction will be unsafe within the terms of the authorities only rarely and only where the 'necessary minimum evidence to establish the facts of the crime has not been called' so that the elements have not been proved or in the rare case where the evidence is plainly so inadequate and threadbare or the witnesses so discredited that the trial Judge concludes that a conviction must necessarily be unsafe and the interests of justice therefore compel discharge."

I think the position would be clarified by this sort of omission of reference to the jury. The issues are whether there is evidence on each element of the case, and whether any of that evidence is plainly so inadequate and threadbare or the witnesses so discredited that the trial Judge concludes that a conviction must necessarily be unsafe and the interests of justice therefore compel discharge.

In Varlack the Board held that the trial judge had correctly rejected the no case submission, and the respondent's conviction was restored. On another point, it held that a good character direction should have been given even though the accused's defence involved admissions of bad conduct, but that here the omission of that direction had made insufficient difference to the trial to affect the verdict.

For the sake of a bit of mental exercise, one might compare the law on no case submissions to that on applications of the proviso. The latter, insofar as relevant here, involves considering whether, in the absence of an error that occurred at trial, the jury could have acquitted the accused. So whereas the no case issue is whether the jury could convict, the proviso issue is whether the jury could acquit.

As can be seen from the cases on the proviso (see Index to this site, entries under "Proviso" and "substantial miscarriage of justice"), the courts are not of one mind on how to decide whether a jury could acquit. Again, the difficulties arise from the court having to decide what a jury could do.

Just for the sake of tossing around ideas, what if the appellate court's task were to be seen as deciding whether there is a defence case that should go to a jury? The error at trial would have to link to the defence case, but, assuming it did, should the court quash a conviction and order a retrial if there is a defence case that is not tenuous (inherently weak or vague)? Each side should meet the same criteria of adequacy on the question of whether its case should go to the jury, whether before or at trial (prosecution case considered by the judge) or by way of retrial (defence case considered on appeal). Discuss.

Breach of right to legal advice

Failure by the police to advise a suspect – now the accused - of his right to legal advice can result in exclusion of evidence against him. This exclusion might also extend to evidence of things found as a consequence of what he said. That, while exciting, is not the thing that interests jurists. They are interested in the basis for exclusion of that evidence.

Is the basis for exclusion the need to ensure a fair trial, or is it the need to uphold broader policies such as the need to maintain control over the conduct of agents of the state and to prevent the administration of justice being brought into disrepute?

Why does the difference between these bases for exclusion matter? Because a different form of decision process is appropriate to each. On the one hand, there are decisions that proceed by way of application of rules. In these, if the right has been breached, exclusion of the tainted evidence is an automatic consequence. On the other hand, there are decisions that involve a balancing of competing interests. In these, the seriousness of a breach of the right is weighed against the public interest in holding the accused responsible for the alleged wrongdoing, and the balance is determined by applying a criterion of proportionality: whether exclusion of the tainted evidence would be a proportionate response by the court to the seriousness of the breach in this case.

The right to a fair trial is an absolute right, and it seems inapt to apply to it a decision process that involves balancing of competing interests. So it is necessary to know whether breach of the right gives rise to fair trial concerns, or to wider public policy concerns.

Cases noted here in previous blogs illustrate the different approaches. See the Index
, and in particular Carr v Western Australia (HCA,blogged 25 October 2007), R v Singh (SCC, 2 November 2007), and Gafgen v Germany (ECtHR, 3 July 2008).

In Salduz v Turkey [2008] ECtHR 1542 (27 November 2008) the Grand Chamber addressed the consequences of a breach of this right (para 55):

"...the Court finds that in order for the right to a fair trial to remain sufficiently "practical and effective" ... Article 6 § 1 requires that, as a rule, access to a lawyer should be provided as from the first interrogation of a suspect by the police, unless it is demonstrated in the light of the particular circumstances of each case that there are compelling reasons to restrict this right. Even where compelling reasons may exceptionally justify denial of access to a lawyer, such restriction - whatever its justification - must not unduly prejudice the rights of the accused under Article 6 ... . The rights of the defence will in principle be irretrievably prejudiced when incriminating statements made during police interrogation without access to a lawyer are used for a conviction."

This indicates some qualification on the need to give the suspect the information about his right to legal advice ("... as a rule ... unless ... compelling reasons to restrict this right"), and if the circumstances of the case are such that the right has been breached this means that there would be "in principle" irretrievable prejudice if the evidence is admitted. This comes close to a rule of exclusion. It would be a rule if the Court had said "The rights of the defence will, as a matter of principle be irretrievably prejudiced ...".

Supporting the view that the Court was not laying down a rule are the points made when the Court applies the "principles" to the present case (para 56 - 63). These are rather confusing as they include comments on matters the Court does not have to decide (58) and they refer to the applicant's youthfulness while also noting that the police procedure was being applied to everyone (60, 61). The Court focuses on how the breach of rights affected the applicant's trial (57, 58), in particular noting that the trial court treated the tainted statement as central evidence which other evidence in the case confirmed. This approach does not look like the application of a rule of exclusion.

If the decision process is not the application of a rule, it is not necessary to refer to breach of the right as going to the fairness of the trial. Policy fairness, not trial fairness, should be the context for the decision. However the Court, without defining trial fairness, considered that this breach did go to trial fairness.

I do not suggest that trial fairness is necessarily the wrong basis for the admissibility decision. A fair trial is one where the law is accurately applied to facts determined impartially. It could be argued that absence of legal advice might give rise to an unreliable statement, so that if the court relied on it that would skew the proceedings by causing partiality (giving improper weight to prosecution evidence). It could even be argued that such a statement would not be voluntary in the sense that the law requires, and that the use of such evidence would be of questionable reliability and would similarly render the trial partial.

The trouble with that view, focused as it is on the proper weight of the tainted evidence, is that questions of the weight of the evidence are usually for the tribunal of fact once the evidence is admissible. A coerced confession is not necessarily unreliable. Its rejection by the court is really a matter of public policy.

Courts in New Zealand tend to justify exclusion of evidence tainted by breach of the right to legal advice on unreliability grounds (see the cases mentioned in Fig 4 of my draft paper on improperly obtained evidence). Nevertheless, as that paper shows, the pattern of decisions follows that of decisions based on balancing of competing values. It seems to be a matter of the right results for the wrong reasons.

Issue estoppel: rule or discretion?

What place do rules have in modern evidence law?

Should the admissibility of evidence of prior misconduct, for which the accused has been tried and acquitted, be determined by a rule, such as issue estoppel, or by a discretion?

That was the main issue in R v Mahalingan [2008] SCC 63 (14 November 2008).

Before looking at how this was addressed in that case, it is worth recalling that the rules of evidence should promote the ascertainment of the truth, that a trial must be fair to the accused but fairness to the prosecution is also important although not overriding, and that evidence of an alleged fact does not have to establish that fact beyond reasonable doubt before it is admissible as part of the case for either side.

This last point is illustrated by Bayes' Theorem.

In Mahalingan the Supreme Court unanimously ordered a retrial on aggravated assault. After the original trial on that charge the accused had been acquitted of attempting to pervert the course of justice, it having been alleged that he had telephoned a witness before the aggravated assault trial and tried to persuade that person not to incriminate him. Should evidence of that alleged telephone conversation be admissible at the retrial on the aggravated assault?

The minority (Deschamps, Abella and Charron JJ) approached this consistently with the propositions about the law of evidence that I have set out above. To be admissible, the evidence of the telephone call need only be established on the balance of probabilities (166).

That standard is applied as a matter of policy, and is not a requirement of logic, as Bayes' Theorem demonstrates.

The minority rejected an argument that the rule concerning issue estoppel should apply in criminal law. Various reasons for this rejection were advanced by Charron J, who delivered the joint judgment of the dissenters. Most importantly she held that (132):

"The application of issue estoppel as an absolute rule precluding the admission of prior acquittal evidence in all cases regardless of context is inconsistent with the basic rule favouring the admission of all relevant evidence, subject to countervailing concerns."

The countervailing concerns are adequately expressed in existing concepts and provisions: abuse of process, character evidence admissibility, rules against multiple convictions and collateral attack, and the pleas of autrefois acquit and autrefois convict; s 11(h) of the Charter is also relevant (84). Such of those matters as were relevant would be considered by the judge at the retrial, and the evidence was not rendered inadmissible by issue estoppel which is only an appropriate rule for civil cases.

McLachlin CJ delivered the judgment of herself and Binnie, LeBel, Fish and Rothstein JJ. Issue estoppel is retained in criminal law but in a revised form (to correct its drift into difficulty) so that it now precludes the prosecution from relitigating an issue that has been resolved in the accused's favour in a previous criminal proceeding, whether on the basis of a positive fact finding or on a reasonable doubt (2, 22, 26).

The policies behind this are the desirability of avoiding inconsistent verdicts, the need to uphold the principle of finality, and the need to ensure fairness to the accused.

This last matter, fairness to the accused, does not mean fairness in the sense of a fair trial, but rather it means fairness in the public policy sense. The Chief Justice elaborated her use of the expression "fairness to the accused" at 39:

"In my view, it is clear that fairness to the accused requires that an accused should not be called upon to answer allegations of law or fact already resolved in his or her favour by a judicial determination on the merits. This is the most compelling rationale for retaining issue estoppel in criminal law, as it goes to the core tenets of our criminal justice system. The state has the right to charge an accused and to prove the facts at a trial of the charge. If a judge or jury conclusively decides a fact in favour of the accused, including via a finding of a reasonable doubt on an issue, then the accused should not be required in a subsequent proceeding to answer the same allegation. To require, in effect, a second defence of the issue would be to violate the fundamental function of res judicata."

This requires a determination, in each case, of whether the issue in question has been previously decided in the accused's favour (33):

"Only issues that were either necessarily resolved in favour of the accused as part of the acquittal, or on which findings were made (even if on the basis of reasonable doubt) are estopped."

That, I suggest, will operate capriciously. The accused has the burden of showing that the issue was decided in his favour (23), and his ability to meet this burden may depend on what he was previously charged with, and how many issues he raised at the earlier trial. He might diminish his chances of successfully relying on issue estoppel if he raised multiple issues, even though a genuinely innocent accused would put everything in issue.

In New Zealand we have crept away from issue estoppel in criminal law: R v Davis [1982] 1 NZLR 584 (CA), Bryant v Collector of Customs [1984] 1 NZLR 280 (CA), R v Coombs [1985] 1 NZLR 318 (CA), R v Fatu [1989] 3 NZLR 419 (CA), R v Degnan [2001] 1 NZLR 280 (CA), Fox v A-G [2002] 3 NZLR 62 (CA). See also Z v Dental Complaints Assessment Committee [2008] NZSC 55 (blogged here 25 July 2008) especially at paras 57-59, 125-127, for discussion of the use of criminally determined matters in civil proceedings, a topic also addressed in abuse of process terms, without reference to issue estoppel. That trend suggests that the minority approach in Mahalingan would be favoured here. We have regarded the jurisdiction to prevent an abuse of process by, inter alia, excluding evidence on public policy grounds, as a potentially powerful means of ensuring fairness in the wider sense. This contrasts with the majority judgment in Mahalingan, where abuse of process was described as a broad, somewhat vague concept that varies with the eye of the beholder, reserved for obviously egregious abuses of the Crown power, to be relied on successfully only extremely rarely (42):

"To protect parties from relitigation, abuse of process would need to be cast in a less discretionary form than it now takes. Therefore, considering the high threshold for proof and the unpredictability of its operation, it is unlikely that the doctrine of abuse of process adequately achieves the fairness goal that underlies the doctrine of issue estoppel."

That may reflect the emaciated form of the abuse of process jurisdiction in Canada. In other legal systems it may be relatively (I feel I am entitled to use the word "relatively" in view of my recent brush with smugness) strong and an adequate substitute for the rule against issue estoppel.

I should add, lest I be accused of regarding Canadian law as unduly flaccid, that the Charter provides the remedy of discretionary exclusion (s 24(2)) in terms that will usually make resort to the common law unnecessary: R v O’Connor (1995) 103 CCC(3d) 1 (SCC) per L’Heureux-Dube J at para 70-72. Under s 24(2) the determination is whether admission of evidence obtained in a manner that infringed or denied a Charter right or freedom would bring the administration of justice into disrepute. Common themes had been evident between the common law and Charter jurisprudence. For example, in R v Mack (1990) 44 CCC(3d) 513 (SCC) Lamer J, for the Court, addressed police conduct of an investigation that amounted to entrapment, and held that admitting evidence obtained through such conduct would bring the administration of justice into disrepute. He noted (para 77) that the same principle applied with respect to the common law doctrine of abuse of process. The dominance of the Charter does not render irrelevant Lamer J’s statement of basic principles in Mack.

Nevertheless, the majority in Mahalingan seem to distrust the usefulness of abuse of process. True it is that criticisms for vagueness can always be levelled at concepts that can only be expressed in general terms. Harmless fun can be had in making such criticisms, as occurred in argument in Ngan v R SC8/2007, 14 August 2007 at pp 32-33 (jibes which misfire, as the “high sounding principles” in the Charter are also in the New Zealand Bill of Rights Act 1990). And Blanchard J, the jester in that argument, set out his own general principles in R v Shaheed [2002] 2 NZLR 377 (CA) in defining the criterion for discretionary exclusion of improperly obtained evidence, a formulation that has been adopted in s 30(2)(b) Evidence Act 2006[NZ]: “...determine whether or not the exclusion of the evidence is proportionate to the impropriety by means of a balancing process that gives appropriate weight to the impropriety but also takes proper account of the need for an effective and credible system of justice.” [emphasis added; cf para 156 of Shaheed]

Judges do have a sense of what such general concepts mean. As cases applying them accumulate, patterns emerge and these aid the prediction of how the general concepts will work in particular instances.

Exclusion of improperly obtained evidence

Users of my method for analysing discretionary exclusion of improperly obtained evidence will be interested to see that in R v Horsfall [2008] NZCA 449 (30 October 2008) the Court ruled inadmissible evidence obtained through an improperly conducted search where the offending had attracted a sentence of over 4 years imprisonment. I have included this in my draft paper.
