Be it enacted by the Senate and House of Representatives in General Court assembled, and by the authority of the same, as follows:

Notwithstanding the provisions of section 15 of chapter 138 of the General Laws, the board of license commissioners of the city of Cambridge may decrease the hours during which sales of alcoholic beverages not to be drunk on the premises may be made; provided, however, that said board shall hold a public hearing concerning the public need for such decrease; provided, further, that any licensee affected by such decrease shall be given two weeks notice of such public hearing; and provided further, that no licensee authorized to make sales of alcoholic beverages not to be drunk on the premises shall be prohibited from making such sales after 10 o'clock ante meridiem and before 11 o'clock post meridiem. A licensee whose hours are decreased pursuant to the provisions of this act may not be barred from opening the premises between the hours of 8 o'clock ante meridiem and 10 o'clock ante meridiem provided that no sales of alcoholic beverages shall be made during the hours when such sales are prohibited by said board. Subject to the provisions of this act, said board shall have discretion to affect the hours of (i) an individual licensee authorized to sell alcoholic beverages not to be drunk on the premises; or (ii) all licensees authorized to sell alcoholic beverages not to be drunk on the premises. A licensee aggrieved by any such decrease in hours may bring a civil action in the nature of certiorari against said board pursuant to section 4 of chapter 249 of the General Laws.
