I have read of provisions that were excepted (not whole treaties) but don't recall specifically where that was. I'll give it a look when I have time as the reference would prove useful. Jay's name comes to mind in that context. I'll bookmark the thread to remind myself to get back to you when I complete the research.

If you're referring to John Jay's treaty of 1794, that was attacked as unconstitutional for a number of reasons, but most stridently on the grounds that it was a commercial treaty, and as such usurped Congress' power over commerce. But it doesn't appear that the courts ever ruled that way.
