On May 29, 2012, he was found guilty by the Senate of Article II of the Articles of Impeachment filed against him for his failure to disclose to the public his statement of assets, liabilities, and net worth. Twenty out of twenty-three senators voted to convict him. A two-thirds majority, or 16 votes, was necessary to convict and remove Corona from office. Corona responded by declaring that "ugly politics prevailed" and his "conscience is clear." This marked the first time that a high-level Philippine official has been impeached and convicted. Senator Joker Arroyo denounced the verdict, ending his statement with "I cannot imagine removing a Chief Justice on account of a SALN. Today, we are one step from violating the constitution and passing a bill of attainder. No one can stop us if we do not stop ourselves. This is not justice – political or legal. This is certainly not law, for sure it is not the law of the constitution. It is only naked power as it was in 1972. I haven't thought that I would see it again so brazenly performed but for what it is worth, I cast my vote. If not for innocence falsely accused, of offenses yet to exist, and if not for the law and the constitution, that we were privileged to restore under Cory Aquino, then because it is dangerous not to do what is right. When soon we stand before the Lord, I vote to acquit". Senator Pia Cayetano explained her vote by stating that "the failure to declare $2.4 million and some 80 million pesos is not minor."
