COMMONWEALTH vs. KEVIN W. WHELAN.

LIACOS, C.J. In this case, and in a related case which we decide today, we clarify the scope of the territorial jurisdiction of police officers employed by the Metropolitan District Commission (MDC). In this case, an MDC police officer twice stopped and subsequently arrested an individual who was allegedly driving an automobile while under the influence of intoxicating beverages and allegedly committing other related automobile (c. 90) violations. A judge of the District Court dismissed the complaints, holding that the police officer acted outside of his jurisdiction when he made the

stops and arrest. Because we hold that the police officer was acting within his jurisdiction, we reverse the decision below and remand for further proceedings.

We summarize the facts. At approximately 9:05 P.M. on April 3, 1988, Officer Michael R. Scalese of the MDC police department was on duty transporting a civilian in his police cruiser when he observed the defendant operating a motor vehicle on Broadway in Somerville. [Note 1] Officer Scalese observed the defendant's vehicle make an abrupt lane change and almost strike Scalese's police cruiser. Officer Scalese activated his cruiser's emergency lights and stopped the defendant's vehicle on Broadway in Somerville. The defendant stated that he did not have a motor vehicle operator's license. Scalese told the defendant to follow in his car behind the police cruiser to the MDC Lower Basin station. En route, the defendant stopped following the police cruiser and proceeded onto Main Street in the Charlestown section of Boston. [Note 2] Officer Scalese followed, and stopped the defendant on Main Street. He then observed that the defendant's speech was slightly slurred, and that the defendant smelled of alcoholic beverages. The officer directed the defendant to perform several field sobriety tests, which the defendant failed to perform to the officer's satisfaction. Officer Scalese arrested the defendant for operating an automobile while under the influence of an intoxicating beverage, in violation of G. L. c. 90, Section 24 (1) (1988 ed.), operating a motor vehicle negligently so as to endanger (c. 90, Section 24), and operating after license or right to operate was suspended (c. 90, Section 23). A judge of the Somerville Division of the District Court Department suppressed the evidence flowing from the stops, and dismissed the complaints on the ground that MDC police officers do not have jurisdiction on either Broadway in Somerville or Main Street in Charlestown. We took this case on our own motion.

Generally, a police officer is powerless to make a warrantless arrest or stop outside his statutorily defined territorial jurisdiction. See Commonwealth v. LeBlanc, 407 Mass. 70, 72, 73 (1990). General Laws c. 92, Section 61 (1988 ed.), delineates the authority of MDC police officers. That section provides, in part: "The police appointed or employed by the commission . . . shall have within the metropolitan parks district, [and] within the cities and towns outside said district wherein property owned by or under management or control of the division of watershed management or the Massachusetts Water Resources Authority is situated . . . all the powers of police officers and constables of towns of this commonwealth" (emphasis supplied).

In order to determine what exactly is the "metropolitan parks district" in which these officers have authority, we look to G. L. c. 92, Section 33 (1988 ed.). That section provides in part: "The commission may acquire, maintain and make available to the inhabitants of Arlington, Belmont, Boston, Braintree, Brookline, Cambridge, Canton, Chelsea, Dedham, Dover, Everett, Hingham, Hull, Lynn, Malden, Medford, Melrose, Milton, Nahant, Needham, Newton, Quincy, Revere, Saugus, Somerville, Stoneham, Swampscott, Wakefield, Waltham, Watertown, Wellesley, Weston, Westwood, Weymouth, Winchester and Winthrop, which shall constitute the metropolitan parks district, open spaces for exercise and recreation in this chapter called reservations; and, for the purposes set forth in this section, the jurisdiction and powers of the commission shall extend to, and be exercised in, said district" (emphasis supplied).

We agree with the Commonwealth's position that the key clause in this section, "which shall constitute the metropolitan parks district," refers to the cities and towns immediately preceding it, and not to "reservations" described in the clause following it. This interpretation is in accord with the general rule of statutory and grammatical construction that a modifying clause of this sort refers to the preceding antecedent. See Druzik v. Board of Health of Haverhill, 324 Mass. 129, 133 (1949). See also Moulton v. Brookline Rent Control

Page 32

Bd., 385 Mass. 228, 230-231 (1982). See generally Strunk & White, The Elements of Style 28-31 (3d ed. 1979).

Other sections of c. 92 support our view that the district is composed of the towns and cities, not the reservations. Section 40 provides: "The commission may accept and maintain as a portion of the reservations under section thirty-three any lands or rights in land which may be given to the commonwealth, provided such lands lie within the limits of the metropolitan parks district, or without such limits but immediately contiguous thereto" (emphasis supplied). The section's proviso would make no sense if the "reservations" alone were considered to comprise the metropolitan parks district. The phrase "within the limits of the metropolitan parks district" suggests an area larger than the sum total of the reservations. Otherwise, it would be impossible for additional land "maintained as a portion of the reservations" to be "without such limits." A fair reading of this section, together with Section 33, shows that the district is composed of the cities and towns listed in Section 33.

Furthermore, there are references in c. 92 to "towns of the metropolitan parks district" (Sections 35 and 54), "cities and towns of the metropolitan parks district" (Section 48), and "the various cities and towns in said parks district" (Section 55). All of these phrases suggest that the metropolitan parks district is composed of the cities and towns listed in Section 33.

The legislative history of the section supports our reading of the statute. Statute 1893, c. 407, established the predecessor of the MDC, the Metropolitan Park Commission. Section 3 provided: "The jurisdiction and powers of said board shall extend to and may be exercised in [twelve cities] and [twenty-five towns]; which cities and towns shall constitute the Metropolitan Parks District" (emphasis supplied). Under this statute, then, the predecessor to the current district was clearly composed of the listed cities and towns, and not merely of the parks within those towns.

Statute 1919, c. 350, Section 123, abolished the metropolitan park commission and established the MDC. That statute provided that "[a]ll the rights, powers, duties and obligations

Page 33

of said boards are hereby transferred to and shall hereafter be exercised and performed by the metropolitan district commission established by this act, which shall be the lawful successor of said commission and board." Section 127 provided that "[t]he commission shall have and exercise over the public property transferred to its charge . . . all the power and authority which the metropolitan park commission has over open spaces for exercise and recreation under [St. 1893, c. 407]" (emphasis supplied).

We do not think that the Legislature, in enacting the current version of G. L. c. 92, Section 33, intended to cut back drastically the size of the metropolitan parks district. See 1 Report of the Joint Committee on Consolidating and Arranging the General Laws 729 (1920); G. L. c. 92, Section 33 (1921 ed.). The metropolitan parks district, under the current statute, as under the original statute, is comprised of the cities listed in the relevant section.

Because Boston and Somerville are both listed in G. L. c. 92, Section 33, they are within the metropolitan parks district. And because MDC police officers have authority "within the metropolitan parks district" under G. L. c. 92, Section 61, Officer Scalese was acting within his territorial jurisdiction when he stopped the defendant in Somerville and Boston and when he arrested the defendant in Boston. [Note 3]

Accordingly, we reverse the order of the District Court, and remand the case for further proceedings.

So ordered.
