The same thing happened in the Roman Empire after the death of Nero. A non-Roman citizen became emperor, and thus precedent was set.
For all you students of legal history out there.
If John Roberts doesn't punt this case to begin with. Considering his vote on Obamacare I doubt this goes anywhere.
On the plus side, if the case goes forward and they take the precedent route, Arnold Schwarzenegger would be eligible to run in 2016 hah!
Up to now, the biggest decision was against Nixon inre the Whitehouse tapes, in my opinion.
