Chapter 22C: Section 63. Employees of colleges, universities, other educational institutions and hospitals; appointment as special officers.
Section 63. The colonel may, upon such reasonable terms and conditions as may be prescribed by him, at the request of an officer of a college, university, other educational institution or hospital licensed pursuant to section fifty-one of chapter one hundred and eleven, appoint employees of such college, university, other educational institution or hospital as special state police officers. Such special state police officers shall serve for three years, subject to removal by the colonel, and they shall have the same power to make arrests as regular police officers for any criminal offense committed in or upon lands or structures owned, used or occupied by such college, university, or other institution or hospital.
Nothing in there states CONTROL OF MOVEMENT OF VEHICLES. You are confusing it with MGL 73 SECT 18.
Chapter 73: Section 18. Control, movement and parking of motor vehicles.
Section 18. The trustees shall make rules and regulations for the control, movement and parking of vehicles on the campus or other land of a state college and may provide reasonable penalties for the violation of said rules and regulations. The trustees may appoint as police officers persons in the employ of such college who in the enforcement of said rules and regulations and throughout the property of such college shall have the powers of police officers, except as to service of civil process. Notwithstanding any other provision of law, all fines and penalties recovered for violation of rules and regulations made under authority of this section shall be accounted for by the clerk of the court and forwarded to the trustees of the division of state colleges who shall deposit the same in the scholarship trust fund of such college for scholarship purposes.
That gives state colleges CHAPTER 90 power. 22c 63 does not give you authority to enforce Chapter 90. The only way a private college in MA has CH90 power, is if they are sworn as specials by that town where they work and that local department gives them CH90 books. If that is the case then you are making the arrest/stop not as a campus cop but as the local cop. The local PD agency is used as the agency code. The state colleges have their own CH90 code and they write the ticket or make teh arrest as a independent agency. This decision was made from the case at Fitchburg State College I believe. 73/18 ONLY APPLIES TO STATE COLLEGES. UMASS has the similar powers under MGL 75.
Chapter 75: Section 32A. Control, movement and parking of motor vehicles.
Section 32A. The trustees shall make rules and regulations for the control, movement and parking of vehicles on the campus of the university and on other land of the university, and may provide reasonable penalties for the violation of said rules and regulations. The trustees may appoint as police officers persons in the employ of the university who in the enforcement of said rules and regulations and throughout university property shall have the powers of police officers, except as to service of civil process. Notwithstanding any other provision of law, all fines and penalties recovered for violation of rules and regulations made under authority of this section shall be accounted for by the clerk of the court and forwarded to the trustees of the university to be deposited in the scholarship trust fund of the university for scholarship purposes.
