When those present at a meeting are of an insufficient number to constitute a quorum, there is no requirement that the meeting be open to the public. See Muncy Creek Twp. Citizens Comm. v. Shipman, 573 A.2d 662 (Pa. Commw. Ct. 1990). See also Pennsylvania Legislative Correspondents’ Ass’n v. The Senate of Pennsylvania, 537 A.2d 96, 98 (Pa. Commw. Ct. 1988) (“Unofficial gatherings of unnamed legislators for whatever purpose do not constitute ‘meetings’ subject to the provisions of the Sunshine Act.”).
