Canada's top court will not weigh into the debate over whether Prime Minister Stephen Harper broke his own law setting fixed dates for federal elections.
The Supreme Court has denied leave to appeal to the group Democracy Watch, which contends Harper broke the law when he called a snap election in 2008, two years into his first mandate.
The court gave no reasons for its decision not to hear the case, which is its custom.
The law - introduced by Harper's government shortly after it won the 2006 election - set fixed dates for elections every four years.
The Federal Court rejected the group's argument in a ruling that was upheld by the Federal Court of Appeal.
Democracy Watch says the appeal court found the law is too vague to prevent the prime minister from calling an election whenever it suits his purpose.
