The 1973 constitution introduced the parliamentary system of government, in the form of the Batasang Pambansa.
It was a plan by president Ferdinand Marcos to institute a corporatist system in which every sector would have a single organization approved and controlled by him, with elections derived from sectoral organizations that have separate and officially sanctioned voter lists.
However, Filipino society was too fluid and democratic traditions too strong for Marcos to impost corporatism; he instead appointed legislators to represent sectors.
[1] In the Batasang Pambansa, the distribution of seats were as follows:[2] In Congress, the allocation was as follows:[3] The peasant sector covers the agricultural group, which includes all persons who personally and physically till the land as their principal occupation, agricultural tenants and lessees, rural workers and farm employees, owner-cultivators, settlers and small fishermen The sector of the disabled covers the physically and socially disabled.
Aside from the indigenous cultural minorities, no other law has been passed to facilitate the election of such sectoral representatives, and remains unfulfilled.
[4] The Sangguniang Kabataan (SK) is meant to represent the youth in local legislatures.
