South Dakota HB 1247 (2024) bars local governments from adopting sanctuary policies that limit cooperation with federal immigration enforcement, requiring Sioux Falls and Minnehaha and Lincoln County agencies to comply with ICE detainers.
Signed by Governor Kristi Noem in 2024, HB 1247 prohibits any South Dakota city or county from enacting policies that restrict police, sheriffs, or jails from communicating with federal immigration authorities, sharing immigration status information, or honoring ICE detainer requests. The law authorizes the SD Attorney General to sue noncompliant local governments. Sioux Falls Police Department and the Minnehaha and Lincoln County jails accordingly process ICE detainers, share booking information through 287(g)-style channels, and do not issue sanctuary-style directives. Federal courts in similar states have allowed limits on detainer-based prolonged detention without judicial warrants.
Local agencies adopting sanctuary policies expose themselves to AG enforcement and possible loss of state funding; individuals harboring or transporting undocumented persons may face federal prosecution.
