MANILA, Philippines -- Some senators are facing more than one complaint before the Senate Ethics Committee, Sen. Joseph Victor Ejercito said on Wednesday. The ethics committee chairman said the panel convened to pass and adopt its rules, which included notifying the concerned senators of the cases filed against them. At least six senators are facing complaints, including Ronald Dela Rosa, Francis Escudero, Risa Hontiveros, and Ejercito himself. "There are now nine [ethics] cases [before the committee]," Ejercito said, adding that some of the respondents face two complaints. Asked whether the case against Dela Rosa would be tackled first because of some calls to withhold his salary for his prolonged absence, Ejercito said, "We have to amend the rules because it is not in the rules of the Senate." "It might be dismissed if we will hear it now because the issue on 'no work, no pay' is not in our rules," Ejercito said. "We can now move as a committee. We will publish [our rules] within 24 hours then we can act, send notice to respondents," he said in a press briefing. "In the next hearing, we will determine if [the complaint] complied the form and substance. We will tackle each cases one by one," Ejercito added. A civil society group led by former Finance undersecretary Cielo Magno filed a complaint against Dela Rosa for his continued absence from official duties for more than three months. Ejercito was facing an ethics complaint for his alleged failure to act immediately on the case filed against Escudero who had been accused of accepting campaign fund from a contractor. Hontiveros has been accused of "witness tampering" in relation to her investigation on the alleged sexual and labor abuses of some members of the Kingdom of Jesus Christ by its founder Apollo Quiboloy.
