No President has seriously challenged a Supreme Court decision since Abraham Lincoln and that was during a domestic emergency far more severe than the Iraqi war. I am not aware that Congress has ever limited the jurisdiction of Federal courts even though the Constitution gives it that authority. Since the days of John Marshall, the Federal judiciary has asserted its superiority to the other two branches of government, mostly without any challenge. Judicial power must and should be restrained by Congress, even if the Supreme Court and the lower courts were populated with strict constructionists, which of course they are not.
I forget the specifics but I believe that Congress, since 2000, limited the jurisdiction of the USSC but that the Court did an end run and ignored Congress.
