24 V.S.A. App. ch. 411, § 208: Quorum

(a) For the purpose of transacting business, 51 percent of the municipalities served by the District must be represented by at least one member of the Board of Supervisors to constitute a quorum. The members of the Board of Supervisors present may adjourn a meeting at which a quorum is not present to another date. Whenever the number of supervisors attending a meeting shall not be sufficient to constitute a quorum, the Clerk of the District shall so notify the legislative bodies of each municipality in the District, naming those supervisors who shall not have been in attendance.

(b) If a time sensitive action must be taken and a quorum is not present, a quorum may be satisfied by attendance through the use of an auditory electronic device, provided that all supervisors hear each other.
