The Board of Supervisors took its second and final vote on legislation that changes The City’s sanctuary policy. The legislation, introduced by Supervisor David Campos, prohibits city officials from reporting undocumented youth arrested on felony charges to federal authorities for possible deportation. They can only be reported if there is a conviction.

The legislation was approved in an 8-3 vote. Supervisors Michela Alioto-Pier, Carmen Chu and Sean Elsbernd opposed it.

Mayor Gavin Newsom is expected to veto the legislation within 10-days. And the board has enough votes – it takes eight votes to overturn a mayoral veto – to overturn the veto.

Newsom has also said that the legislation is not enforceable since it conflicts with federal law, and the juvenile probation officers’ labor union president supports Newsom. Perhaps it’ll take a lawsuit to resolve this one.
