Region IX and Region XII each had a Regional Legislative Assembly or Sangguniang Pampook, each composed of 18 representative each. They included:[1][2]
17 representatives per region, elected from the different provinces and cities in each region.
1 sectoral representative per region, selected from among the youth, agricultural workers, and non-agricultural workers (industrial labor) of each region. They were selected by qualifications that were the same as members of the Interim Batasang Pambansa.
The candidates for the 34 Regional Legislative Assembly representative positions, 17 each for Region IX and Region XII, were voted on at large by the registered voters of each province and city constituency. The candidates that received the highest number of votes in each constituency were declared their elected representative.[1][2]
