Corona, who was appointed by former president Gloria Macapagal-Arroyo, is being tried in the impeachment court for a number of impeachable offenses
including failure to disclose to the public his assets, liabilities and net worth as required under the constitution.
The Chief Justice is also being tried for partiality in deciding cases in favor of former president Arroyo, who is now under detention for charges in connection with the rigging of last presidential election in which Arroyo was the winning candidate.
Corona was reported to have influenced the court in issuance of a temporary restraining order
which would have allowed Arroyo to leave the country to evade charges.
There are eight charges lodged in the impeachment court which were part of the impeachment complains filed by the opposition who are mostly allied with the present administration under president Benigno Aquino, Jr.
Chief Justice Corona complained during the impeachment trial that he was being persecuted
for taking part in a Supreme Court decision involving the award of lands to tenants of the sugar estate owned by president Aquino's family and relatives.
Under the law agricultural lands should be distributed under certain terms and conditions, to farmers who till the land under the agrarian reform law.
The senate impeachment tribunal is being chaired by senate president Juan Ponce Enrile with the 23 elected senators as impeachment judges.
The impeachment trial began on January 16, 2012. after the Supreme Court justice was impeached by congress last December 12, 2011 with 188 (majority) congressmen voting in favor of Corona's impeachment.
The supreme court justice denied the charges, saying they were fabricated designed to malign his person and destroy the good refutation he has built for him and his family.
Corona said he will abide by the verdict of the impeachment court. Likewise, the administration headed by president Aquino said they will honor whatever decision the impeachment court will render.
Of the 23 senators, 16 must vote in favor of impeachment
in order to convict Corona and only six votes are needed to acquit him.
Voting for or against the impeachment of the chief justice will commence after the court session resumes at 2:00 p.m. Tuesday, Philippine time.
A guilty verdict will remove the chief justice from his position and effectively bar him from holding public office for life.
