Instead of being laughed off as a silly mistake, this deserves serious scrutiny. Where there is one mistake caught only by a fluke, there are probably many more that didn't get noticed. Harper's cannabis crackdown means that our courts are steadily processing more and more small-time cannabis cases. As these cases clog the system, judges will find themselves even more pressed to deal with them quickly, and be paying even less attention to the specific details in each case. These kinds of sentencing mistakes will only happen more often.
