Having concluded that the initiation takes place by the act of filing of the impeachment complaint and referral to the House Committee on Justice, the initial action taken thereon, the meaning of Section 3 (5) of Article XI becomes clear. Once an impeachment complaint has been initiated in the foregoing manner, another may not be filed against the same official within a one year period following Article XI, Section 3(5) of the Constitution.
In fine, considering that the first impeachment complaint, was filed by former President Estrada against Chief Justice Hilario G. Davide, Jr., along with seven associate justices of this Court, on June 2, 2003 and referred to the House Committee on Justice on August 5, 2003, the second impeachment complaint filed by Representatives Gilberto C. Teodoro, Jr. and Felix William Fuentebella against the Chief Justice on October 23, 2003 violates the constitutional prohibition against the initiation of impeachment proceedings against the same impeachable officer within a one-year period."
