Mass. Gen. Laws ch. 218 § 57A
The justice provided for under section 1 of chapter 211B as the chief justice for the juvenile court department, in addition to his judicial powers and duties, shall, subject to the superintendence authority of the supreme judicial court as provided in section 3 of chapter 211, have the powers, authority and responsibilities set forth in section 10 of chapter 211B; provided, however, that the clerk of such court shall have responsibility for the internal administration of his office, including personnel, staff services and recordkeeping.

A chief justice shall hold said office for a term of 5 years, and shall be eligible to be reappointed for additional 5 year terms. A chief justice, so appointed may be removed from that office prior to the expiration of his term provided, however, that any such removal is not for arbitrary or capricious reasons.
Said chief justice shall also prescribe official forms to be used in all courts of the juvenile court department and in juvenile sessions of the district court department.
