“(1) that a man cannot be tried for a crime in respect of which he has previously been acquitted or convicted”
“(2) that a man cannot be tried for a crime in respect of which he could on some previous indictment have been convicted; (3) that the same rule applies if the crime in respect of which he is being charged is in effect the same, or is substantially the same, as either the principal or a different crime in respect of which he has been acquitted or could have been convicted or has been convicted …. (7) that what has to be considered is whether the crime or offence charged in the later indictment is the same or is in effect or is substantially the same as the crime charged (or in respect of which there could have been a conviction) in a former indictment and that it is immaterial that the facts under examination or the witnesses being called in the later proceedings are the same as those in some earlier proceedings; (8) that, apart from circumstances under which there may be a plea of autrefois acquit, a man may be able to show that a matter has been decided by a court competent to decide it, so that the principle of res judicata applies;”
“It matters not that incidents and occasions being examined on the trial of the second indictment are precisely the same as those which were examined on the trial of the first. The court is concerned with charges of offences or crimes. The test is, therefore, whether such proof as is necessary to convict of the second offence would establish guilt of the first offence or of an offence for which on the first charge there could be a conviction.”
“On a complaint for a common assault they were to determine whether such assault was accompanied with any felonious intention; on that question they have adjudicated, and their decision is final. They are like any other Court of competent jurisdiction. It is the same as if the party had been convicted by a jury of the assault. I see no difference in principle whether a party has been convicted or acquitted. Suppose a party had been acquitted by a jury of an assault, and he was afterwards indicted for the felony which involved that assault; it is clear, if he did not make the assault, he could not be guilty of that which includes and depends upon the assault. There is no difference in such a case whether the party was acquitted or convicted. In either case the felonious intention would be negatived, and the party could not afterwards be indicted for a felony. The question here at issue has, I think, been well raised by the demurrer.”
“Again the same test appears and was applied. Would the evidence which was necessary to support the indictments be sufficient to convict of the earlier charge? If the prisoner had been acquitted by the magistrates he could not have been later charged with the felony. To prove an assault with intent would involve proving an assault: but he would have been acquitted of an assault. Furthermore, a court having jurisdiction to decide the matter would have decided that there was no felonious intent. The same reasoning applied where there had been a conviction before magistrates. The prisoner could not later be convicted of the felony. That would be for two reasons: (1) that the felony would involve the assault: it would include and depend upon the assault: and he had already been convicted of the assault; (2) a court having jurisdiction to decide the matter would have held that there was no felony.”
“We must bear in mind the well established principle of our criminal law that a series of charges shall not be preferred, and, whether a party accused of a minor offence is acquitted or convicted, he shall not be charged again on the same facts in more aggravated form.”
“For the doctrine of autrefois to apply it is necessary that the accused should have been put in peril of conviction for the same offence as that with which he is then charged. The word "offence" embraces both the facts which constitute the crime and the legal characteristics which make it an offence. For the doctrine to apply it must be the same offence both in fact and in law… I would add one further comment. [Lord Morris] in his statement of the law, accepting what is suggested in some dicta in the authorities, extends the doctrine to cover offences which are in effect the same or substantially the same. I entirely agree with [Lord Morris] that these dicta refer to the legal characteristics of an offence and not to the facts on which it is based: see R v. Kendrick and Smith. I have no difficulty about the idea that one set of facts may be substantially but not exactly the same as another. I have more difficulty with the idea that an offence may be substantially the same as another in its legal characteristics; legal characteristics are precise things and are either the same or not. If I had felt that the doctrine of autrefois was the only form of relief available to an accused who has been prosecuted on substantially the same facts, I should be tempted to stretch the doctrine as far as it would go. But, as that is not my view, I am inclined to favour keeping it within limits that are precise.”
“In my opinion, if the Crown were to be allowed to prosecute as many times as it wanted to do on the same facts, so long as for each prosecution it could find a different offence in law, there would be a grave danger of abuse and of injustice to defendants. The Crown might, for example, begin with a minor accusation so as to have a trial run and test the strength of the defence. Or, as a way of getting round the impotence of the Court of Criminal Appeal to order a new trial when, as in this case, it quashes a conviction, the Crown might keep a count up its sleeve. Or a private prosecutor might seek to harass a defendant by multiplicity of process in the different courts.”
“... I must observe that nearly the whole of the English criminal law of procedure and evidence has been made by the exercise of the judges of their power to see that what was fair and just was done between prosecutors and accused. The doctrine of autrefois was itself doubtless evolved in that way.”
“The doctrine of autrefois protects an accused in circumstances in which he has actually been in peril. It cannot, naturally enough, protect him in circumstances in which he could have been put in peril but was not.”
“I quite agree that “acquittal on the merits” does not mean that the jury or the magistrate must find as a matter of fact that the person charged was innocent; it is just as much an acquittal upon the merits if the judge or the magistrate were to rule upon the construction of an Act of Parliament that the accused was in law entitled to be acquitted as in law he was not guilty, and to that extent the expression “acquittal on the merits” must be qualified, but in my view the expression is used by way of antithesis to a dismissal of the charge upon some technical ground which had been a bar to the adjudicating upon it. That is why this expression is important, however one may qualify it, and I think the antithesis is between an adjudication of not guilty upon some matter of fact or law and a discharge of the person charged on the ground that there are reasons why the Court cannot proceed to find if he is guilty.”
“If, moreover, the context in which a charge is summarily dismissed is a rationalisation or reorganisation of the prosecution's case, so that, no doubt in recognition of the difficulties that may lie ahead in the successful prosecution of the original charge, it is decided to substitute therefor a new charge which is regarded as more appropriate to the facts, then the consensual dismissal of the original charge, upon the substitution of the new one, will not give rise to the application of the doctrine of autrefois acquit: Broadbent v High. Admittedly, the prosecution have not been put to their election; but that is merely because it is at their instance that the new and substituted charge is preferred. Apart from anything else, including the fact that to hold otherwise would be contrary to common sense, it is plainly undesirable that the prosecution should be obliged to keep alive a charge upon which they have no intention of seeking a conviction merely to meet any subsequent attempt to apply the doctrine of autrefois acquit in circumstances which are both technical and without merit.”
“The application of this principle may not, however, be sufficient if the acquittal on the first charge would be inconsistent with the conviction on the second. The record would then say both that the defendant was guilty, and that he was not guilty, of the conduct in question; and that does not seem tolerable. This was not so in the present case: the defendant was not guilty of obtaining the money by the deception alleged; and he was guilty of stealing it.”
“So far as the present case is concerned, the magistrates' court had not embarked upon a trial of the merits. The adjudication of not guilty did not reflect anything other than the prosecution decision, which had already been communicated to the defence, that they would not be proceeding with the charge under s.20 but would instead prefer the more serious charge under s.18. There is no possibility here that the defence were under any misapprehension as to what the procedure, mistakenly and wrongly adopted, was as a matter of fact intended to achieve … We have come to the clear conclusion that since there was no question of anybody being misled by what happened in the magistrates' court…, the decision of [the judge] not to uphold the plea in bar was entirely correct.”
“The present case goes farther. In Dabhade there was no inconsistency on the record: an acquittal of obtaining by deception contrary tosection 15 of the Theft Act 1968 is not inconsistent with a conviction for theft contrary to section 1 of that Act on the same facts. But an acquittal of an offence under section 20 is inconsistent with a conviction of an offence under section 18 on the same facts. The greater offence includes the lesser. The justification is that the acquittal was not a “real” acquittal. Real or not, it was presumably recorded and the record is false.”
“In the present context “on the merits” is a phrase which distinguishes between where a court is in a position to convict but does not do so and the position where a court is unable to proceed to consider the question of conviction or acquittal because it has no power, or thinks it has no power, to adjudicate.”
“For the principle of autrefois to apply, the defendant must have been put in jeopardy. Quite apart from all other requirements, he must demonstrate that the earlier proceedings that he relies upon must have been commenced - that is, by plea in summary proceedings, or by his being put in charge of the jury in a trial on indictment.”
“Herein assistance is to be derived from two cases. The first is R v. Tonner [1985] 1 W.L.R. 344, where it was held that on an indictment a trial starts, not upon the arraignment of the defendant but once a jury has been sworn and the defendant has been put in their charge. In dealing with a situation in the magistrates' court, in R v. Hammersmith Juvenile Court, ex parte O.(1987) 86 Cr.App.R. 343 , the court there held that a trial in a juvenile court begins when the plea is taken. It seems to me that in proceedings before justices, this is the logical moment whereat a defendant begins to be in peril of a conviction. Although it could be said that when a preliminary point is taken before plea, battle has been joined, as it were, yet all that is due to happen at that stage is that the point is decided either for or against the defendant; he is not in peril of conviction of the charge he is called upon to answer as a result of that decision. I am of the opinion that the decisions in various defendants' favour in most of the cases cited to us, and to which I have already referred, are explicable on the basis that the defendant has entered a plea of not guilty.”
“One has to bear in mind now that there are distinct procedures to be gone through when a person is summonsed to face offences which are triable either way before the plea is taken, but he says that at the latest the accused is in jeopardy from the moment of plea. Support for that proposition is derived from the words of Rougier J in Williams v DPP [1991] All ER at page 659, where he says that when an accused is to be tried on indictment the moment when he is in peril is when the jury are sworn to try him and he is put in their charge. The fact that he may have been arraigned at some much earlier stage, (and frequently nowadays is), is irrelevant. Until the jury have been sworn although he may be acquitted by order of the Judge he cannot be convicted. That is certainly correct but why the position should be so different in the Magistrates’ court it is difficult to see. On the facts of the present case there was never any risk of the defendants being convicted by the court sitting on 12th November unless they had entered pleas of “Guilty” and, probably not even then, unless the prosecution advocate was there.”
“If it be permissible to compare the situation with a trial on indictment, it would seem to be difficult to contend that the trial has not started when the accused has been arraigned and asked to plead to the indictment.”
