The Supreme Court of Canada has thrown out two separate cases from the Montreal area.
In the first, the court rejected three separate efforts to start class-action cases over property taxes in Montreal and Longueuil.
The court says lawsuits are not the way to fight problems with city taxes.
The cases arose out of the controversial city mergers in 2001.
The homeowners objected to the way the new municipalities set property-taxes and they wanted refunds.
Lower courts in Quebec rejected the cases and Canada's highest court has now upheld those rulings.
Blue collars
In the second case, the court rejected an effort to sue the union that represents Montreal's 5,000 blue collar workers.
A one-day illegal strike by 300 city workers caused a massive traffic jam in the city downtown core in 2003.
A Montreal commuter, Boris Coll, said tens of thousands of people were unfairly inconvenienced by the strike.
Lower courts had disagreed over the lawsuit.
The Supreme Court's rejection of both these cases effectively means they are dead.
