MATTAPOISETT — The Mattapoisett Select Board confirmed that an upcoming Special Town Meeting will take place on Saturday, Oct. 4 at 1 p.m. at Old Rochester Regional High School.

With only one issue on the warrant, meeting attendees will discuss the expansion of the select board from three members to five members. However, since the expansion has already been signed into law by Gov. Maura Healey, special town meeting voters will not be able to repeal the approved legislation.

The board describes the upcoming meeting vote as a “non-binding referendum,” meaning that the result of the vote holds no enforceable action.

According to Town Administrator Michael Lorenco, the Special Town Meeting will cost approximately $3,500. This estimate includes projected costs for Town Counsel, clerk services, audio and visual elements and for a police officer to be present at the meeting.

“This isn’t going to put the town in any financial burden,” said Lorenco.

Created by Paul Criscuolo, the petition that brought the Special Town Meeting to fruition sought to maintain a three-person select board in Mattapoisett after a petition to expand the board was approved at Town Meeting in May. 

The initial citizens petition that was approved at Town Meeting was created by Nicki Demakis, who argued that an expanded select board would allow for a greater diversity in perspective.

Criscuolo received over 280 signatures at the time he submitted the petition. Therefore, the town is legally obligated to hold the meeting even if the result has no impact on the inevitable expansion.

The bill to expand the board was enacted on Thursday, Aug. 21 in the Massachusetts House and Senate, and was signed into law by Healey the following day.

“At this point, the petition is no longer valid,” said Lorenco. “When they wrote it, [the expansion] wasn’t signed into law. Now it’s signed into law so it’s a non-binding article, according to counsel.”
