Since the elected chairman is one of the mayors of Metro Manila, the role to his constituency gave less attention. Thus, the Congress of the Philippines, composed of the Senate and the House of Representatives, passed Republic Act No. 7924 creating the Metropolitan Manila Development Authority (MMDA) on March 1, 1995. President Fidel V. Ramos appointed Prospero Oreta, who did not run in the Malabon municipal election, as the first Chairman of the MMDA in May 1995 and made him independent of the Metro Manila mayors.
