The Federal Court of Appeal dismissed immediately from the bench Harper's appeal of the Federal Court ruling that the women wearing niqabs were illegally refused admittance to a Citizenship ceremony. The Appeal judges stated that the original trial judge had explained the legal case in such a watertight manner that there was no grounds for appeal. If a court rules that the Utah judge's ruling has no validity in Canada then it's all over before it starts.
