There is no explicit limit on the role of the supreme court. Nor is there any actual explicit role in the constitution for it. It's just one sentence. I think they even once tried a criminal case. It deals with lots of constitutional issues, but Congress could basically just defund it and remit constitutional complaints to other venues if they wanted to. This is done in part with FISA and other national security measures. Congress deemed there to be no venue in the courts for a complaint.
