Gilberto Duavit Sr. won the special election to serve the final 14 months of former representative Manuel Sanchez's term.

Six candidates participated including Rogelio Sanchez Silvestre, Sanchez's nephew, former House majority leader Francisco Sumulong, former assemblyman Gilberto Duavit Sr. of the opposition Nationalist People's Coalition (NPC), and three independent candidates: chess grandmaster Rosendo Balinas Jr., lawyer Eduardo Inlayo and peasant leader Elmer Panotes.

[1] Cainta and Taytay were expected to provide the swing votes as none of the candidates are from those two municipalities, and that many residents there were immigrants from other parts of the country.

The low turnout of 37% was blamed on Rizal's traffic problems, and the inability of employees and students to cast their votes when they reside outside the district during the workweek/school week.

[4] After his election victory, a member of the Duavit family has served as representative of Rizal's 1st district up to the current 19th Congress.
