A law firm headed by Trump administration advisor Stephen Miller has filed an appeal contesting California's sanctuary state status. The firm, America First Legal, seeks to overturn a dismissal of a lawsuit against a 2017 state law that bans local law enforcement from cooperating with federal immigration officials.

The firm stated that the district court judge who denied the initial challenge last year incorrectly applied the South Lake Tahoe doctrine, which prevents local governments from challenging state laws in federal court. The initial challenge had support from the Justice Department and former Attorney General Pam Bondi.

The first Trump administration filed a similar challenge in 2018, which District Court Judge John Mendez denied, stating that refusing to help federal officials is not the same as impeding them.

Bush, ruled in 2018 that the law did not impede federal immigration officials. ” America First Legal, founded by Stephen Miller in 2021, stated that the recent dismissal creates a conflict for law enforcement officers between state and federal laws.

AFL Senior Counsel James Rogers said the state has placed its officers in a position where they must violate either state or federal law. He added that the district court's decision denied officers the right to challenge the law in court. Immigration and Customs Enforcement has conducted operations in California since the start of Trump's second term, with some local politicians opposing their presence.

Appeal The appeal aims to restore cooperation between local law enforcement and federal immigration officials. America First Legal argues that the South Lake Tahoe doctrine, which treats cities as agents of the state, deprives municipalities like Huntington Beach of their ability to protect communities.

AFL Counsel Ryan Giannetti said the case concerns whether law enforcement can protect communities and whether judges can use certain legal rules to shield states from the effects of their policies. The firm described the doctrine as flawed in its application to this matter.

The appeal follows a period of active federal immigration enforcement in the state.
