In what circumstances will the trial judge rule that a gun found by the police can be adduced in evidence?

British Columbia, Canada

The following excerpt is from R. v. Burlingham, 1993 CanLII 6884 (BC CA):

In view of the trial judge's reference to Wray [see Wray v. The Queen (1973), 1973 CanLII 21 (SCC), 10 C.C.C. (2d) 215, 33 D.L.R. (3d) 750, [1974] S.C.R. 565], it might be thought that he had ruled that the gun, ex. 13, being physical evidence found by the police, could be adduced in evidence. Subsequent proceedings, which will be described in a moment, demonstrate that no such ruling was made at that time. Thus, it is not correct, as counsel for the accused argued, that the trial judge “reversed himself” on this question when he later admitted the gun into evidence.
