This election is the first under the
1987 constitution. The districts were based on the ordinance to the constitution. Unlike in the
Regular Batasang Pambansa where each province and some cities elected members of parliament
at-large in
multi-member districts for more populous provinces and cities, the 1987 constitution reintroduced the
single-member districts for more populous provinces and cities. These include the changes in the number of seats per province and city, as compared with the Regular Batasang Pambansa, with each at-large district having one seat unless specified: • Division of
