On December 12, 2011, 188 of the 285 members of the House of Representatives of the Philippines voted to transmit the 56-page Articles of Impeachment against Supreme Court Chief Justice Renato Corona.
Of the six exclusive grounds laid down in Section 2, Article XI of the Constitution, the three grounds of (1) betrayal of public trust, (2) graft and corruption, and (3) culpable violation of the Constitution were distributed among the eight Articles of Impeachment tried by the Senate starting January 16, 2012.
On May 29, 2012, the Senate, voting 20–3, convicted Corona under Article II of the Articles of Impeachment filed against him pertaining to his failure to disclose to the public his statement of assets, liabilities, and net worth.
Below are the eight Articles and the respective arguments presented by the prosecution and defense panels in support of their allegations.
Prosecution: The First Article of Impeachment alleges that Corona betrayed public trust by his “track record marked by partiality and subservience in cases involving the Arroyo Administration,” which is traced to his history as President Gloria Macapagal-Arroyo’s chief of staff, spokesman, and acting Executive Secretary.
In relation to this, a press release by Senator Franklin Drilon enumerated some 19 cases where Corona allegedly voted in favor of the Arroyo Administration.
