An appeals court in Ottawa has affirmed the constitutionality of the way the Canadian government allows Canadian financial institutions to share the information of their U.S. account-holders with the authorities in the U.S., ending the latest round of a years-long battle by two U.S. born Canadian women who are known informally to their supporters as "Gwen and Kazia." 

A long-awaited appellate court hearing in a years-long challenge of Canada's Foreign Account Tax Compliance Act-implementation legislation will take place on March 30, sources involved in the matter are reporting. 

Two dual Canadian/U.S. citizen plaintiffs in a long-running legal effort to block Canada’s implementation of the U.S.’s Foreign Account Tax Compliance Act have launched an appeal in Canadian Federal Court in Ottawa, after their most recent attempt to challenge the law was dismissed in July. 

A Federal Court in Ottawa on Monday dismissed the latest legal effort by two dual Canadian/U.S. citizens to block Canada’s implementation of the U.S.’s Foreign Account Tax Compliance Act, dealing a blow to thousands of Americans with dual citizenship and consequent tax obligations not just in Canada but, supporters of the plaintiffs argue, around the world.

 As last week's trial over the constitutionality of the Canadian government's enforcement of America’s FATCA legislation ended on Friday, the Alliance for the Defence of Canadian Sovereignty (ADCS), which brought the case on behalf of two individual plaintiffs, said an appeal would ultimately follow, "no matter who wins."

A trial in which a group of Canadian/American citizens are seeking to challenge the constitutionality of the Canadian government's enforcement of America’s FATCA legislation is set to begin on Monday in a federal courthouse in Vancouver, British Columbia, and will be broadcast live via a "webcast", according to sources involved in the lawsuit.
