R v Britten

The appeal concerned a criminal conviction for possession of an offensive weapon, specifically a firearm. The appellant, R v Britten, was convicted by a trial judge of possessing a rifle found in the footwell of the front passenger seat of a car in which he was a passenger. The Court of Appeal of South Australia was required to determine whether the evidence established beyond reasonable doubt that the appellant had possession of, or had exercised access to, the firearm.

The central legal issue was whether the appellant's DNA found on the rifle, coupled with his prior inconsistent statements and testimony from a disputed facts hearing, was sufficient to prove beyond reasonable doubt that he possessed the firearm on the date of the offence, or had exercised access to it. The prosecution argued that the DNA evidence, particularly on the trigger guard, bolt, and grip, indicated the appellant had handled the weapon. The appellant, however, had provided conflicting accounts, initially denying any knowledge of the rifle and later admitting to having handled it the previous day, attributing his forgetfulness to methadone use.

The Court of Appeal reasoned that while the DNA evidence strongly indicated the appellant's biological material was on the rifle, it did not exclude the possibility that this contact occurred on a date prior to the alleged offence. The appellant's admission of handling the rifle on the day before the police stop, while incriminating, could not form the basis of a conviction for the offence charged on the later date due to the way the trial was conducted. The court found that the evidence did not establish beyond reasonable doubt that the appellant had custody of, or had exercised access to, the rifle on the specific date of the alleged possession.

Consequently, the Court of Appeal allowed the appeal, set aside the conviction, and ordered that an acquittal be entered.
