The New Hampshire Supreme Court ruled Wednesday that a man can have a license plate reading “COPSLIE,” saying that the regulation the Division of Motor Vehicles cited to bar him from owning that plate was “unconstitutionally vague.”

David Montenegro’s application for the plate was rejected under a regulation that bars plates “which a reasonable person would find offensive to good taste,” the court said.

Citing a decision in another case, the court said it concluded the restriction “ ‘authorizes or even encourages arbitrary and discriminatory enforcement’ . . . and is, therefore, unconstitutionally vague.”
