This study analyzes violations of constitutional rights to a healthy environment caused by gold mining in Lantung District, Sumbawa. It evaluates mining management through the lenses of Ecological Justice, the Public Trust Doctrine, and Ecological Governance. Using normative legal research and a socio-legal approach, the study examines the 1945 Constitution, Environmental Protection Law (PPLH), and Mining Law alongside secondary data. Findings reveal that mining activities have triggered water pollution, deforestation, and sedimentation, violating Articles 28H(1) and 33 of the 1945 Constitution. Weak enforcement against illegal mining (PETI) and inadequate state supervision demonstrate a failure in the state’s role as a trustee. A significant imbalance exists where local communities bear environmental burdens while external actors reap the economic benefits. This research recommends strengthening the constitutional agenda to guarantee ecological rights for future generations. This can be achieved through transparent, participatory governance that prioritizes environmental preservation over short-term extraction.
