Canada Opposition members of Parliament forced through legislation Wednesday that requires the Conservative government to meet its stiff commitments under the Kyoto accord to combat global warning.
The Tories have suggested the government would simply ignore the bill if it became law, but constitutional experts have said the government must respect laws passed by Parliament.
The bill passed 161-113 in the House of Commons and is expected to swiftly pass through the Senate, which is dominated by Liberals. That would leave Prime Minister Stephen Harper in the sticky situation of either respecting the Kyoto accord or facing a possible vote of no-confidence.
"They are bound to it. It's the law of the land," said bill sponsor Pablo Rodriguez. "The prime minister cannot cherry pick laws. He's not the new emperor of Canada."
He said that if the Harper government did not respect the law, "we go to the courts."
