The province is currently represented in the lower house of the Congress of the Philippines through its first and second congressional districts.
[1] The chartered city of Butuan, despite being enumerated as part of the territory of neither successor province,[1] was designated as Agusan del Norte's seat of provincial government and became part of its congressional representation.
Under the new Constitution which was proclaimed on February 11, 1987, the Agusan del Norte was grouped with the highly urbanized city of Butuan and reapportioned into two congressional districts;[2] each district elected its member to the restored House of Representatives starting that same year.
However, in 1935, all senatorial districts were abolished when a unicameral National Assembly was installed under a new constitution following the passage of the Tydings–McDuffie Act, which established the Commonwealth of the Philippines.
Agusan del Norte has been represented in the lower house of various Philippine national legislatures since 1987, through its first and second congressional districts.
