48 Both of the applicant's grounds here, and the submissions advanced in support of them, appear to be predicated on a view that Filippetti and Lai laid down a principle of law to the effect that where an accused is charged with exclusive possession of a prohibited drug in circumstances in which the accused is a co-occupier of the premises in which the drug is found, the prosecution is obliged to negative possession of the co-occupiers. Those cases establish no such principle. Each of them turned on the application of the ordinary principles applicable to circumstantial evidence - in particular, that an inference of the accused's guilt cannot be drawn if, on the evidence, an inference consistent with his or her innocence is reasonably open. In other words, in any circumstantial evidence case, the prosecution is obliged to exclude any reasonable possibility consistent with the accused's innocence. So it was in Filippetti that Street CJ concluded there was not enough evidence to rule out as a reasonable possibility, that the buddha sticks were in the possession, or exclusive physical control, of one of the other occupants of the house. Likewise, in Lai, the evidence was simply insufficient to exclude the reasonable possibility that someone other than the appellant had put the heroin in the ceiling and had exclusive physical possession of it. Each of those cases turned upon their own facts and the evidence adduced. So does the present case.
