I think any candidate that doesn't subscribe to an elections outcome, so long as the election has a prescribed method for a redress of grievances, is automatically disqualified from being considered in said election.
Its an assumption the system makes: If you are participating in an election, you also agree that 1) an election is happening and you support that, and 2) that you will abide by its outcomes.
I don't see how you can in good faith be participating in an election and unwilling to accept its outcome. The assumption that you will abide by its outcomes seems baked into the cake.
