MANILA, Philippines -- The passport of Rodolfo Lozada Jr., key witness in the national broadband network controversy, has been submitted to the Court of Appeals by one of the lawyers of the security men that escorted Lozada out of the Ninoy Aquino International Airport upon his arrival in early February from Hong Kong.

Lozada confirmed the passport that Eric Santos, counsel for Rodolfo Valeroso, turned over to the appellate court Thursday at the resumption of the hearing on the petition for a writ of amparo filed by Lozada?s brother Arturo.

On inspection, the passport contained information on Lozada?s departure from the Philippines and his arrival and departure from Hong Kong but had no stamp by the Philippine immigration of his return to the Philippines last February 5.

Lozada had told the Senate investigating the NBN fiasco that when he arrived, his passport was taken from him.

The hearing started with Justice Regalado Maambong questioning Lozada's counsel on why the most important part of their motion -- Lozada?s affidavit -- was not submitted to the court.

Maambong said the affidavit would be a basis of their decision to either grant or dismiss the writ.

"Why is it that you don't have the affidavit of the person? Why of all people, you exclude the affidavit of the person seeking protection order?" Maambong asked.

But the lawyers said that the affidavits would be culled from the Senate hearings and the copy to be submitted in the next hearing.

"You can't drop to us voluminous documents [from the Senate]. What we are concerned here is the protection order," Maambong said.

Lozada's wife, Violet, took the witness stand earlier on Thursday to detail the threats received by her husband.
