MANILA -- The political party of former President Gloria Macapagal-Arroyo is studying the possibility of questioning the legality of the Truth Commission before the Supreme Court (SC).

“That would depend upon the recommendation of our legal panel whether we would be filing the necessary petition to question the legality of the creation,” Lakas-Kampi-CMD spokesman and legal counsel Raul Lambino said in an ambush interview.

“As a lawyer and as a professor of constitutional law, I think the Truth Commission is unconstitutional. The creation of the Truth Commission is unconstitutional,” Lambino added.

Earlier today, Justice Secretary Leila de Lima affirmed the constitutionality of the creation of the Truth Commission through President Benigno "Noynoy" Aquino III's Executive Order No. 1 signed Friday.

The minority bloc at the lower chamber of Congress is set to announce their party position on the commission this week.

Meanwhile, Arroyo as representative of Pampanga's second district attended the minority caucus at the House of Representatives and again, avoided questions from the media when asked about the Truth Commission.

The Truth Commission, headed by former Chief Justice Hilario Davide, is set to investigate the anomalies during the Arroyo regime like the NBN-ZTE deal, the "Hello, Garci" scandal and the fertilizer fund scam. (Kathrina Alvarez/Sunnex)
