Any unlawful conduct on the part of a person concerned in the administration of justice which is prejudicial to the rights of parties or to the right determination of the cause; as “misconduct of Jurors,” “misconduct of an arbitrator.” The term is also used to express a dereliction from duty, injurious to another, on the part of one employed in a professional capacity, as an attorney at law, (Stage v. Stevens, 1 Denio [N. Y.] 267,) or a public officer, (State v. Leach, 60 Me. 58, 11 Am. Rep. 172.)
