The trial court erred in granting homeowners an injunction against the county Road Commissioner barring the county from enforcing ordinances banning encroachments on a county road leading to a popular public hiking trail.  Courts may not enjoin enforcement of the laws, which in this case make encroachments a misdemeanor offense.  Contrary to the homeowners’ claim, CEQA does not require any EIR before enforcement of the anti-encroachment ordinance.  And the homeowners suffer no irreparable harm by being prohibited from violating the law.
