The Act makes no distinction between elected and appointed bodies so long as the governmental body has rulemaking or quasi-judicial authority. See, e.g., Op. Tex. Att'y Gen. No. JC-0060 (1999); Willmann v. City of San Antonio, 123 S.W.3d 469, 478 (Tex. App.-San Antonio 2003, pet. denied) ("A committee appointed by a governmental body constituting less than a quorum of its members may be subject to [the Act] because it falls either within a definition of the term 'governmental body' or as a subcommittee of a governmental body.").
