Occidental Mindoro Provincial Board
The Occidental Mindoro Provincial Board is the Sangguniang Panlalawigan of the Philippine province of Occidental Mindoro.
The members are elected via plurality-at-large voting: the province is divided into two districts, each having five seats. A voter votes up to five names, with the top five candidates per district being elected. The vice governor is the ex officio presiding officer, and only votes to break ties. The vice governor is elected via the plurality voting system province-wide.
The districts used in appropriation of members is not coextensive with the legislative district of Occidental Mindoro; unlike congressional representation which is at-large, Occidental Mindoro is divided into two districts for representation in the Sangguniang Panlalawigan.
Aside from the regular members, the board also includes the provincial federation presidents of the Liga ng mga Barangay, the Sangguniang Kabataan and the Philippine Councilors League. Occidental Mindoro's provincial board also has a reserved seat for its indigenous people.
