18- 185 C.M.R. ch. 110, § 3
Hearings shall be conducted in the county in which the property interest that is the subject of the hearing is located, unless at the complete discretion of and in the best judgment of the Clerk of the Commission there are overriding issues related to the convenience of the parties or the efficiency in conducting the hearing that require the choice of a location outside of the county. The exact location of any hearing shall be suitable for a full presentation of all evidence. In choosing the exact location of the hearing, the Clerk may take into consideration factors including but not limited to the capacity of the proposed site to accommodate the anticipated number of persons attending the hearing, the needs of anyone attending the hearing who might have a disability, the degree to which the proposed site is perceived by the parties as being neutral to each party, and the degree to which the proposed site can meet the technological requirements of any party presenting evidence. Regardless of the selected hearing location, the county commissioner appointed for the hearing shall be a commissioner of the county in which the subject property is located.
