The final version prohibits law enforcement officials from asking about a person's immigration status or participating in immigration enforcement efforts.
In arguing against the measure, Republicans in the Assembly invoked the 2015 shooting of Kate Steinle by an undocumented immigrant in San Francisco, arguing that sanctuary protections make communities less safe.
The California Values Act would not necessarily make California the country's first "sanctuary state". Following sharp dissent from law enforcement officials and Brown's intervention, it was scaled back significantly. But it now allows local police to respond to notification requests and transfers immigrants to U.S. Immigrations and Customs Enforcement if the individual has committed one of the more than 800 crimes outlined in The Trust Act.
"This comes as a relief that there are some legislators that are really listening", said Pablo Alvarado, executive director of the National Day Laborer Organizing Network.
Yet even in deep-blue California, the original sweeping prohibitions, which would have kept federal immigration authorities out of local jails and largely barred them from receiving any help from state law enforcement, proved impossible to jam through. The version that was passed would allow local authorities to share information with federal authorities, and the feds would still be allowed into county jails to question immigrants who have been detained.
This year's legislation not only raises new, much-needed revenue for housing, it reasserts the state's interest in getting more housing built while preserving the say local communities have in their own neighborhoods. The California Police Chiefs Association is now neutral on the bill, but the California State Sheriffs' Association still opposes it. "It's going to protect the criminal at the expense of the law abiding citizen".
All in all, the bill's passage is a big victory for advocates of immigrants' rights, despite opposition from sheriff's organizations in the state. They've passed legislation and filed lawsuits aimed at protecting immigrants, combating climate change and blocking any future attempt to build a registry of Muslims.
Earlier Friday, a federal judge in Chicago ruled against the Trump administration and an order issued by Attorney General Jeff Sessions requiring so-called sanctuary cities to cooperate with immigration agents in order to get federal funding in the form of public safety grants.
