SAN FRANCISCO — Mendocino County officials and the U.S. attorney for Northern California may be trying to resolve their long-running dispute over records from the county's medical marijuana program out of court

The county has asked a federal judge in San Francisco to quash a subpoena for the records. A hearing in the case had been set for Tuesday, but was canceled on Monday.

County Counsel Tom Parker says federal prosecutors asked to have the case removed from the calendar. Parker declined comment on the move's significance.

But Adam Wolf, a lawyer representing Northern California medical marijuana growers in the case, says a cancellation at this stage of the proceedings often signals that settlement talks are in the works.

The records in question relate to a now-defunct county program that issued permits to medical marijuana growers.
