Whether a local government's cancellation of a Williamson Act land-preservation contract is reviewable by administrative mandamus rather than only by ordinary mandamus.
Holding
Yes. Cancellation is an adjudicatory administrative decision reviewable under Code of Civil Procedure section 1094.5.
Reasoning
Administrative mandamus applies to final administrative decisions made after a legally required hearing, the taking of evidence, and discretionary factual determinations. The Williamson Act requires a public hearing and requires the local agency to weigh evidence in making the statutory cancellation findings.
The proceeding is adjudicatory rather than legislative. The landowner initiates it by petition, the city council acts as an arbiter after hearing supporters and opponents, and the decision directly concerns a particular parcel rather than generally prescribing land-use policy for an area.
