To suddenly be told by the Canadian government that they are not valid, at least under Canadian law, is a very disruptive and destructive development, if it is upheld. Fortunately, there is no need for the court to go there if it wants to dismiss the divorce petition, since the lack of Canadian residency by either of the parties to the same-sex marriage would be sufficient grounds to do so, unless the court is minded to find some sort of defect with the residency requirement. In that case, of course, it would have to confront this other argument. The article reporting on this development says nothing about any specific Canadian statute upon which Mr. Gaudet is relying.
