The Exeter Town Council did not violate the OMA when a quorum of its members convened for an unnoticed meeting because the evidence established that the Exeter Democratic Town Committee convened for a meeting and not the Exeter Town Council. The OMA expressly provides that "political part[ies,] organization[s], or [a] unit therefore," is not a "public body" within the OMA. See R.I. Gen. Laws 42-46-2(3).
