The founders of the*Federal*Constitution had attempted to anticipate contested or very close presidential election results and thus had made provisions to*deal*with such an eventuality. There is a strict timetable between the presidential election and the swearing in of the*successful*candidate as president. There is a constitutional provision that the*House*of Representatives can elect the president should any presidential election result in a tied vote or no candidate securing the required majority in the electoral*college. On the other hand, if there are disputed presidential election results in any of the states that determine the destination of electoral*college*votes then it is the responsibility of the Supreme Court to make a fair and fast judgements to resolve the issue.
