The case was filed against the US government by Glamis Gold, a Canadian mining company engaged in the mining of precious metals. The project area was located within the California Desert Conservation Area, and designated areas of special cultural concern, and near, though not on, the Quechan Indian Tribe’s reservation lands.

The case was a consolidation of two class actions brought under the Prison Litigation Reform Act of 1995 (PLRA), which allows prisoners to sue for violations of constitutional rights. California's prisons were designed to hold about 80,000 prisoners, but at the time of filing, the system held about 156,000. In both class actions, overcrowding was found to constitute an 8th Amendment violation because of a serious lack of access to basic medical care, with one case dealing specifically with prisoners with serious mental illness.
