That's what a Canadian judge told the jury in a marijuana possession case, where the defendant claimed he possessed the marijuana for medical reasons (though he apparently didn't qualify for some reason for Canada's medical marijuana exemption): The judge instructed the jurors "to retire to the jury room to consider what I have said, appoint one of yourselves to be your foreperson, and then to return to the court with a verdict of guilty."
Yesterday, the Supreme Court of Canada reversed the conviction (R. v. Krieger), concluding -- as do American courts -- that the right to criminal jury trial means that the judge may not categorically direct the jury to render a guilty verdict, even if the judge believes that the factual evidence against the defendant is overwhelming.
Thanks to R.G. Newbury for the pointer.
