The Town of Blackstone uses an Open Town Meeting style of legislature. The local government consists of a 5 person Board of Selectmen, and an appointed Town Administrator.

The Board of Selectmen call the town meetings into existence by issuing the warrant, which is the list of items--known as articles--to be voted on, with descriptions of each article. The Moderator officiates the meeting by reading each article, explaining it, and making sure the rules of parliamentary procedure are followed, interprets voice votes and counts other votes. All registered voters are free to attend and vote on any and all articles in the open town meeting.

The Town Administrator's reponsibilities are to make appointments of certain department heads, serve as Public Safety Director and as Procurement and Personnel Officer for the Town. In addition, his or her duties require budget preparation, inventory of all town equipment, and oversight of town departments.
