Last week, Judge William Orrick, a federal district judge for Northern California, permanently blocked President Trump’s executive order cutting federal funds to sanctuary cities that refuse to comply with federal efforts to detain and deport undocumented immigrants. In his ruling, the judge writes that the executive order violates the US Constitution’s principles of federalism and separation of powers. This decision is the result of a lawsuit brought by the city and county of San Francisco and Santa Clara County challenging the executive order issued in January this year that aimed to cut federal funding for cities which did not comply with a statute that prohibits state and local governments from refusing to relay information about the immigration status of those in their jurisdiction to federal immigration authorities. In his decision, Judge Orrick states: “The Counties have demonstrated that the Executive Order has caused and will cause them constitutional injuries by violating the separation of powers doctrine and depriving them of their Tenth and Fifth Amendment rights.”
