(Applicable to District Court and Superior Court)

(a) Nature of the Proceedings. All criminal contempts not adjudicated pursuant to rule 43 shall be prosecuted by means of complaint, unless the prosecutor elects to proceed by indictment. Except as otherwise provided by these rules, the case shall proceed as a criminal case in the court in which the contempt is alleged to have been committed.

(b) Special Provisions for District Court. The District Court shall have jurisdiction to try all contempts committed therein except those prosecuted by indictment. Whenever a contemnor asserts his right to a jury trial in District Court, the trial shall be held before a jury in District Court. The contemnor's only right of appeal shall be to the Appeals Court.

(c) Disqualification of the Judge. The contempt charges shall be heard by a judge other than the trial judge whenever the nature of the alleged contemptuous conduct is such as is likely to affect the trial judge's impartiality.
