The present-day provinces of Apayao, Benguet, Ifugao and Kalinga, as well as the highly urbanized city of Baguio, formed part of the old (pre-division) Mountain Province's representation until 1969. Since 1969, the representation of Mountain Province has been confined only to the limits of the former sub-province of Bontoc.
History
As the undivided Mountain Province (1908–1966)
Initially being excluded from representation in the lower house of the Philippine Legislature in 1907, the then non-Christian-majority areas of the Philippines — which included the undivided Mountain Province — were finally extended legislative representation with the passage of the Philippine Autonomy Act in 1916 by the United States Congress. The Revised Administrative Code (Act No. 2711) enacted on March 10, 1917, further elaborated on the manner by which these areas would be represented.[1] The non-Christian areas were to be collectively represented in the upper house's 12th senatorial district by two senators, both appointed by the Governor-General.[1] Three assembly members, also appointed by the Governor-General, were to represent the Mountain Province and the chartered city of Baguio in the lower house as a single at-large district. The appointment of these members of the Legislature did not require the consent of the upper house; the appointive legislators were also not necessarily required to be residents of the areas they represented.[2] For example, Assemblyman Pedro Aunario, a resident of Manila,[3] and Senator Lope K. Santos, a resident of Rizal, were among the representatives of the Mountain Province.
Act No. 4203 also abolished the senatorial district system and made the Mountain Province's representation to the National Assembly elective through popular vote; the law divided the province into three districts with definite territorial composition.[4] The only sub-province which belonged to more than one district was Bontoc: the eastern portion consisting of the present-day municipalities of Barlig, Bontoc, Paracelis, Natonin, Sabangan, Sadanga and Sagada were represented as part of the undivided province's first district, while the western portion which formerly belonged to the now-defunct Lepanto sub-province (Bauko, Besao and Tadian) were represented as part of the third district.
The enactment of Republic Act No. 4695 on June 18, 1966, made the sub-province of Bontoc into a full-fledged province that retained the name "Mountain Province."[5] Per Section 10 of R.A. 4695 the three incumbent representatives of pre-division Mountain Province continued to serve their respective districts until the end of the 6th Congress.[5]
