Canada's highest court has agreed to hear a North Vancouver man's challenge of a federal law abolishing accelerated parole.
Christoper John Whaling started serving his six year sentence on weapons charges in September of 2010.
At the time, he was given credit for time already spent in custody and was supposed to be released in June of 2011, but that was cancelled after the Conservative government abolished accelerated parole in march of that year.
The first-time offender filed a constitutional challenge based on a claim Whaling was being punished retroactively.
A lower court judge agreed the penalty amounts to double jeopardy because you can't be disciplined twice for the same crime.
The Supreme Court of Canada has now agreed to hear his case.
