happen on May 10, 2010 and you will know already if there was a failure of elections. So between May 10 to June 30, Congress must elect whoever will because the head of the government temporarily until a new election is called," he said.

Congress members have until June 30, 2010 before their term expires or a gap of 50 days starting from the day of voting.

"My term will end on June 30, 2010. This current term will end on June 30 although I’ll continue to be the Senate president until I am replaced. If I will get re-elected, we will reorganize Congress under a new Congress. So if there is no election, there is nothing to reorganize. So the Constitution anticipated that and they said that you must pass a law for Congress to determine who will act as temporary president," Enrile said.

Although the 1987 Constitution establishes the so-called line of succession, it will be "broken" if there will be a failure of election, according to Enrile.

"There will be no Senate president, no Speaker of the House (to fill in the position of the president and vice president), beyond June 30, that is the problem because the president in place will be the president until June 30. What is problematic is June 30. So Congress now, between May 11 all the way to June 30 must act," he said.

Enrile expressed belief that there would be sufficient time to enact a new law to address this issue.

"I will not object to a contingency plan in the form of a succession order in case there is no president, by that time," Defensor-Santiago said. "The proposal is why don’t we pass a law now so that if the contingency takes places, we are prepared. I have no objection. Let just have an abundance of caution to this legal phrase."
