Wed, 25 Jan 2012 11:40:01 +0100 (AP) - Philippine Internal Revenue Commissioner Kim Henares reads documents as she takes the stand as witness for the prosecution during an impeachment trial of Supreme Court Chief Justice Renato Corona (not pictured) on the sixth day of the trial at the Philippine Senate in Manila, Philippines, Wednesday, Jan. 25, 2012. The Philippines' first impeachment trial of a Supreme Court justice started on Jan. 16, in a major battle of President Benigno Aquino III's anti-corruption campaign targeting his detained predecessor and her allies. Corona was impeached by the House of Representatives in December on corruption allegations as well as accusations that he tried to block prosecution of former President Gloria Macapagal Arroyo, who has been detained on vote-rigging charges.
