Hi
I think you are "whistling in the wind"
1. Do you really think that the court would rule that Section 15 would apply to everyone in the world outside Canada? Not likely.
2. If you read the Zhu decision closely http://decisions.fct-cf.gc.ca/en/2013/2013fc155/2013fc155.html His application was cancelled before 87.4 became law and was asked prior to that to perfect his application, so he had a reasonable expectation that it would be processed. Read further in the decision about what the Judge stated about 87.4 of the Regulations.
" In my view, subsection 87.4(1) is not applicable in the circumstances. The provision cannot serve to strike a validly rendered visa officer's decision. The provision expressly deals with undecided applications, not decisions. While it is true that Mr. Zhu's application remained undecided after March 29, 2012, a decision was rendered by the Officer on May 17, 2012 before the provision was passed into law. Had the application not been decided before subsection 87.4(1) was passed into law, then the application would have been terminated. At the time the decision was rendered, the law was not in effect and the decision was valid."
