"Receipts" and not say-so, will be the name of the game in Senate President Pro Tempore Panfilo "Ping" M. Lacson's investigation as incoming chairman of the Senate Blue Ribbon Committee.

Lacson said this as he is set to lead the probe into substandard and ghost flood control projects.

In an interview on Tuesday, Sept. 9, that this approach will apply to the claims of Pacifico and Cezarah Discaya linking some lawmakers and officials to corruption.

"First of all, I will look for receipts. I will not rely on the say-so of others hook, line and sinker. In my privilege speeches, I do not rely on mere reports or testimonies. Instead, I ask myself what evidence do I have to support what I will say?" he said in Filipino in an interview on DZBB radio.

He said he will also take a closer look at the supposed ledgers and vouchers containing the amounts supposedly given to Department of Public Works and Highways (DPWH) officials and lawmakers.

Lacson stressed that to ensure fairness in the investigation, he will be on the lookout for "selective" testimonies from the Discayas and other resource persons.

Also, he said he will start where the previous Blue Ribbon Committee hearings on the flood control projects left off.

Meanwhile, Lacson said he does not see any conflict with the work of the independent commission to be formed by Malacanang, since the Blue Ribbon Committee's work is in aid of legislation.

He said he will even furnish the independent committee with evidence gathered during the Blue Ribbon probe, to help in the prosecution of those found liable.

"No, they won't because they are separate. If we find evidence we will pass it to the independent commission. I have talked to DPWH Sec. Vince Dizon about this," he said when asked if the Blue Ribbon committee probe will clash with that of the independent commission.

Lacson said he has furnished Dizon with evidence based on his first privilege speech. He said he will furnish Dizon with new evidence after his second privilege speech.
