The Supreme Court of Canada has reserved judgment on whether Kelly Ellard should face a fourth trial in the murder of Victoria teenager Reena Virk.

The court said it would release written decision in the future, but did not say when.

Ellard, 27, has faced three trials in the 1997 murder — two ending in convictions and a third in a hung jury.

A judge ruled in September that the latest conviction be overturned because the judge in that trial didn’t explicitly warn the jury about how much weight to put on the testimony of a witness.
