In his petition for prohibition and injunction, Garcillano, through his lawyer Eddie Tamondong, said the wiretapped tapes were illegal and inadmissible in court.

He said the high court should prohibit lawmakers from using the wiretapped conversation as basis for their committee report.

"You cannot use something that is illegal as basis for an official committee report," Tamondong said Friday.

Garcillano on Thursday asked the Supreme Court to nullify the warrant of arrest issued by the House after he failed to appear in its investigation of the wiretapped tapes where he and the President were allegedly heard discussing how to manipulate the results of the election.
