San Francisco is appealing a federal judge's ruling, striking down a key provision of a new city program providing basic health care for uninsured residents.
The city filed an appeal with the Ninth U.S. Circuit Court of Appeals in San Francisco Thursday morning.
San Francisco was set to begin requiring employers with more than 20 workers to start subsidizing the health plan next week.
However, U.S. District Judge Jeffrey Wright ruled on Wednesday that the mandate would violate a 1974 federal law designed to prevent inconsistencies in the health coverage for employees who work for the same company, but live in different jurisdictions.
The judge's ruling came in a lawsuit filed by the Golden Gate Restaurant Association.
