The case involved a petition to disqualify former President Estrada from running for mayor due to his prior plunder conviction. The Supreme Court ruled that the pardon granted to Estrada by former President Arroyo was absolute and restored his right to seek public office. The Court noted that a presidential pardon cannot be limited by legislative action and that Estrada's pardon was complete and unambiguous based on its wording. Thus, the COMELEC did not commit grave abuse of discretion in allowing Estrada's candidacy. The petition for disqualification was dismissed.
