Assuming that a res gesta situation has arisen, it may now be considered what forms the declaration may take. Presumably the declarant will not be held to all those niceties of speech which are exacted from a witness: a declaration will not be excluded because it asserts or denies the very fact to be determined by the court. If in Comm. v. Hackett the deceased had said: “Dan Hackett has murdered me,” it would have been as admissible as his actual statement that Hackett had stabbed him. It is further submitted that the general rule excluding opinion evidence should similarly be relaxed in the case of a statement part of the res gesta. In some cases, an utterance that might have qualified for admission as part of the res gesta has been rejected as opinion. But such a statement seems to have been received in R. v. Palmer, where Fisher was allowed to testify that at Shrewsbury, six days before his death, Cook said to him, about ten minutes after drinking a glass of brandy with Palmer and others, not merely that he had been very sick but also, despite the objection of defence counsel, that “that damned Palmer had dosed him.” The reference to Palmer seems to have been based purely on conjecture. The general rule against opinion evidence is based upon two considerations, first that opinions in so far as they are based upon no evidence are worthless, and second that in so far as they are based upon legal evidence they tend to usurp the function of the tribunal whose province alone it is to draw conclusions of law or fact.
