I think that's the right answer. I did some research and discovered that no other country in the world has taken any inspiration from the court challenges program. I don't know if that's because we're unique or more intelligent than other people, or if it's because we're different from everyone else in the world. Who knows? Sometimes reality is stranger than fiction.
Speaking of political fiction, could the federal government use the program if it wanted to challenge a provincial statute but didn't want to do it directly? It could use an organization from a province to challenge the law of that same province, and that challenge would be funded by the federal government.
Is that possible?
