You can't always get what you want

Conservatives find out they can't use a private members bill to backdoor a retroactive tax on union members unless Parliament approves it first.
Of course, they might still get Parliament to approve it -- after all, the Harper Conservatives do have the endorsement of almost four in ten Canadians, AKA the most massive and overwhelming mandate EVAH!

But at least they would have to admit up front that imposing gratuitous mandatory financial reporting requirements on labour unions is the kind of ideological claptrap that might well result in thousands of people getting charged hundreds of dollars in retroactive taxes.
