Law on South Kalimantan province

The Law on South Kalimantan province (Indonesian: Undang-Undang tentang Provinsi Kalimantan Selatan), officially Law Number 8 of 2022 (Indonesian: Undang-Undang Nomor 8 Tahun 2022), is a law passed by the People's Representative Council of Indonesia regarding the existence of the province of South Kalimantan. The law is one of several laws passed with relatively minor changes to provide an updated legal basis for the existence of Indonesian provinces; previously, the legal standing for many Indonesian provinces was based on laws from the era of the United States of Indonesia. However, while other provinces' laws were passed uncontroversially without major change, South Kalimantan's province law was passed with a sudden change of the capital city from Banjarmasin to Banjarbaru. This change led to a court challenge from elements associated with Banjarmasin city, with consequent response from Banjarbaru city.

The change of capital city location enjoyed popular support within Banjarbaru, but faced general opposition from residents and officials of Banjarmasin city. Lawyers representing opponents of the change deemed it "a constitutional coup". On 29 September 2022, the Constitutional Court of Indonesia ruled against the opponents, and the capital officially changed from Banjarmasin to Banjarbaru.
