You need to reread the 20th Amendment to the Constitution. It clearly gives Congress the authority to make the Speaker of the House the successor to the Vice President. The Supreme Court has no say.

OK, now that I have read it: Section 4. The Congress may by law

Doesn't sound clear to me. "May" does not mean "shall". Therefore succession would be challenged. Count on it.
