Petitions for Extreme Risk Protection Orders and Second Amendment Sanctuary Status in Colorado

Extreme risk protection orders (ERPOs) temporarily bar individuals adjudicated as being at risk of violence (including suicide) from buying or possessing firearms.

This cross-sectional study of civil court documents analyzed petitions for ERPOs filed in Colorado from January 2020 to December 2022. All petitions during the study period were included following de-duplication. These include petitions filed by law enforcement and family members against adults allegedly at risk of firearm violence across the state. Data were analyzed on a rolling basis between January 2020 and June 2023. ERPO petition filed in Colorado. Seventy-seven data elements defined a priori were abstracted from all petitions and case files, including respondent demographics, petitioner types (family or law enforcement), types of threats (self, other, mass violence, combination), violence risk factors, and case outcomes (granted, denied). Of a total 338 ERPOs filed in Colorado, 126 (37.3%) occurred in 2A sanctuaries. Sixty-one of these 2A petitions were granted emergency orders, and 40 were full 1-year ERPOs after a hearing. Forty ERPOs (31.7%) were petitioned for by law enforcement. Petitions in non-2A counties were more likely to have been filed by law enforcement (138 of 227 [64.9%] vs 40 of 126 [31.7%]; P
