Two of the complaints allege that Aquino betrayed public trust and violated the constitution for implementing an economic stimulus programme that was ruled unconstitutional by the Supreme Court in July.
A third complaint was filed for an agreement signed with the United States to allow more US troops to stay in the Philippines.
The House of Representative’s Committee on Justice found the three complaints sufficient in form, which means that the charges against Aquino were duly signed by the complainants and verified by lawmakers who endorsed them.
Congressman Neil Tupas, head of the committee, said the approval of the complaints was technical and did not yet deal with the substance of the charges or probable cause.
“The first battleground will be the sufficiency in substance, which will be discussed next week,” he said.
Aquino is prepared for whatever the outcome would be of the House deliberations on the complaints against him, presidential spokesman Herminio Coloma said.
“We recognize Congress as a co-equal branch of government and they are just following the processes under the law,” he said.
Analysts believe that the complaints would not be approved by the House because Aquino has majority support in Congress.
