When the legislation was read a second time in the House of Assembly, the government expressed the view that the amendment would allow the same issues to be canvassed as in an appeal by the accused[75]:
>
> > "[I]t acknowledges that just as in the case of the trial of an accused who is found guilty, there may be errors of law in summing up of the trial judge or other matters which deserve consideration by the Full Court or other appeal courts, in the same way such considerations may arise when an accused person is acquitted ... while the accused person should certainly not again be put at risk, the Crown should be given the opportunity in some way to have the disputed matters of law dealt with by an appeal. So, it was said that it could be done in the way proposed."
> >
> > Section 350(1a) is a beneficial procedure, adopted by Parliament to permit courts to give "authoritative decisions on questions of criminal law for the better administration of justice"[76]. A narrow construction of "arising at the trial" in the sub-section would frustrate the achievement of that purpose. Such a construction should therefore be avoided. The fact that the question of law reserved on the application of the appellant did not strike either the primary judge or the Full Court as falling outside the ambit of "the trial" is not, of course, determinative. Oversights can occur, even in such a fundamental matter as jurisdiction. But the approach taken by their Honours is open unless there is imposed on s 350(1a) of the Act a jurisprudence concerning the commencement of "the trial" which was developed for quite different purposes than those which s 350(1a) was designed to advance. The procedures of stated cases have been notoriously technical. They have presented many questions concerning the last moment at which a judge may be asked to reserve a question of law for the opinion of a higher court[77]. The fact that the Attorney-General or the Director of Public Prosecutions may now, by statute, reserve any question of law after a trial at which a person is acquitted assists in defining the purpose of the sub-section. It suggests that the question of law concerned need not have been raised expressly at the trial. This was the view taken by Cussen J in R v Turnbull[78] of a like provision in Victorian legislation[79]. He considered:
> >
> > "[I]f there was an existing point of law which arose on the materials at the trial, and which might have been taken, it can be said to have arisen at the trial, although no contention as to it had been raised there, and although the judge's attention had not been directed to it at the trial."
>
> A similar opinion was reached by several of the judges of the English Court of Criminal Appeal in R v Mellor[80], including Lord Campbell CJ[81], Cockburn CJ[82], Coleridge J[83] and Martin B[84]. Whilst others took a narrower view, I find the reasoning for a broader approach more consonant with the purposive construction of the provisions and the balance of authority. Particularly is this so in relation to an exceptional statutory provision which permits a prosecution challenge to a legal ruling which led to the acquittal of the accused.
>
> > 2. The approach which I favour is also one which is more realistic when it is remembered that a provision such as s 350(1a) is now to be construed in the context (of which Parliament was presumably aware) of extensive interlocutory determinations in Australian criminal proceedings. These can affect the conduct of a subsequent trial and concern questions of law expected to arise in the trial. Their earlier determination may govern the way in which the whole trial is conducted. A narrow view would require that such preliminary rulings of law, affecting the trial, must be ignored, and the facility for their legal correction after the acquittal of the accused completely lost, although s 350(1a) of the Act was clearly enacted with the general purpose of avoiding such disadvantages for the proper administration of criminal justice.
> >
> > 3. In the present case, it is highly artificial, in the continuous dialogue between the trial judge and counsel placed before this Court, to draw a line in the proceedings of that day at the point at which the respondent was rearraigned and required to plead: disregarding all that happened before that moment for the purpose of deciding whether the contested question of law arose "at the trial". It is sometimes important, for particular purposes, to decide precisely when a trial commenced; for example, to determine whether a new statutory regime will apply to it[85]. In South Australia it has been held that, ordinarily, a criminal trial commences "when the accused having been arraigned before the judge who is to try him, that judge embarks upon the hearing and determination of any preliminary questions or upon the empanelling of the jury"[86]. The point of commencement appears to have been even later at common law[87]. However that may be, such considerations are of little relevance to the meaning of the disputed phrase as it appears in s 350(1a). There, the question in issue is not the delineation of events for the application of a particular legislative regime, the introduction of different procedures or the attachment of new and different rights. It is the provision of the facility for the consideration of a question of law which, having arisen in a concluded trial, may arise again and requires authoritative curial determination. It is a mistake to apply to such a context decisions reached in different contexts for quite different purposes.
> >
> > 4. It would be unacceptably artificial to treat the prosecution's tender of no evidence (referred to in the case stated) separately from the events which are also there described and which preceded that course. If the appellant is correct, the primary judge had no authority to refuse to accept the nolle prosequi tendered by him. If that be right, and if there was no jurisdiction in the judge except to discharge the respondent, all that followed in the purported "trial" was, as a matter of law, completely unauthorised. There was no power in the judge to grant the application to reinstate the request for trial by judge alone. There was no power to rearraign the respondent. There was no power to conduct the abbreviated trial. Nor was there power to find the respondent not guilty on all counts. A clearer case of questions of law "arising at the trial" could hardly be imagined. The narrow view would construe the section as if it empowered the court to "consider and determine any question of law reserved after the commencement of the trial". But that is not what s 350(1a) says. If the transcript of the actual exchanges between the primary judge and counsel at the trial may be used to remove any suggested ambiguity of the case stated, it is worth recalling that the primary judge, after the rearraignment, prefaced his verdicts with the phrase "In those circumstances". The "circumstances" referred to were clearly the decision of the prosecutor to tender no evidence at the trial. That event can itself only be understood by reference to the immediately preceding refusal of the judge to "accept a nolle prosequi".
