The other ground which, in the circumstances, the learned members of the Full Court found unnecessary to consider, related to the admission of portion of a statement made by one of the defendant's witnesses, Magee, to a constable of police shortly after the accident. This witness swore in the course of his examination in chief that the plaintiff's car "jumped out of the cobble-stone gutter back on to the bitumen". This was, in substance, reiterated in cross-examination when, in answer to a question which was intended to elicit that the witness had not seen the respondent's car in any position other than on the earth shoulder of the road, he said "other than when it jumped back on to the bitumen". Thereafter, he was cross-examined concerning certain evidence which he had given at a coronial inquiry and an attempt was made to establish that he had not then said "a word about" the car jumping back or, even, about the "car coming back to the bitumen - that is, the near-side wheel jumping up and coming back onto the bitumen". Other questions in similar vein were asked in cross-examination but what has been set out is sufficient to give some general indication of the situation which the appellant claimed had arisen. At the same time we should point out that a perusal of the transcript leaves us with the impression that there was some confusion as to what it was that the witness was alleged to have said at the trial and to have omitted to say at the inquest. It was in these circumstances that application was made to the learned trial judge to permit the appellant to elicit from the constable evidence of portion of the witness' earlier statement to him. But again, it is by no means clear precisely what it was that the appellant wished to prove. Nevertheless, his Honour allowed the evidence to be given. It is, however, apparent from the statement of his reasons for permitting this to be done that he proceeded upon an erroneous principle. He said: "It appears to me that the criterion which will allow evidence of this character to be adduced is nowhere better stated than by Sholl J. in Woodward v. Shea [1] where he said this: "In other words, is the suggestion of recent invention fairly open to counsel on the answers given by the witness in cross-examination, or if he does not choose to make the imputation is it something to which the jury or any member of the jury might fairly infer?" [1] . It appears to me that the three questions which were asked by Mr. Shannon and the answers which were given clearly fall into that category and it would be open to counsel for the plaintiff, and if counsel did not make the suggestion it would be open to the jury, to suggest or infer that the evidence of Mr. Magee as to the Holden coming back onto the road immediately before the collision was something which he had invented or thought of at some point of time after the evidence given by him at the Coroner's Inquest. On that basis I think the evidence is admissible and I propose to admit it". The principles upon which evidence of earlier statements may be admitted to re-establish the credit of a witness whose credit has been impugned by a suggestion of recent invention are firmly established and a recent statement of them is to be found in The Nominal Defendant v. Clements [2] . In the circumstances it is, we think, desirable to repeat what was then said: "The rule of evidence under which it was let in is well recognized and of long standing. If the credit of a witness is impugned as to some material fact to which he deposes upon the ground that his account is a late invention or has been lately devised or reconstructed, even though not with conscious dishonesty, that makes admissible a statement to the same effect as the account he gave as a witness if it was made by the witness contemporaneously with the event or at a time sufficiently early to be inconsistent with the suggestion that his account is a late invention or reconstruction. But, inasmuch as the rule forms a definite exception to the general principle excluding statements made out of court and admits a possibly self-serving statement made by the witness, great care is called for in applying it. The judge at the trial must determine for himself upon the conduct of the trial before him whether a case for applying the rule of evidence has arisen and, from the nature of the matter, if there be an appeal great weight should be given to his opinion by the appellate court. It is evident, however, that the judge at the trial must exercise care in assuring himself not only that the account given by the witness in his testimony is attacked on the ground of recent invention or reconstruction or that a foundation for such an attack has been laid by the party but also that the contents of the statement are in fact to the like effect as his account given in his evidence and that having regard to the time and circumstances in which it was made it rationally tends to answer the attack. It is obvious that it may not be easy sometimes to be sure that counsel is laying a foundation for impugning the witness's account of a material incident or fact as a recently invented, devised or reconstructed story. Counsel himself may proceed with a subtlety which is the outcome of caution in pursuing what may prove a dangerous course" [1] . What should be observed is that it is for the judge to determine for himself whether the credit of the witness has been impugned in the relevant sense and it is not to the point to enquire whether it would be open to the jury, or to some member of it, as the decision in Woodward v. Shea [2] would seem to suggest, to infer that a suggestion of recent invention had been made. If, according to the view of the learned trial judge such a suggestion is made it raises a subsidiary issue in the case and it is for the judge, having so decided for himself, to instruct the jury how they should deal-with it; if in the view of the judge no such suggestion is made it is for him to instruct the jury appropriately. Secondly, when the suggestion has been made, it is for the judge to satisfy himself that the evidence sought to be adduced is such that it "rationally tends to answer the attack".
