When the owner of such lumber and the owner of the lands or dams do not agree upon the damages, the selectboard of the town where the lands or dams are situated, not being interested therein, shall adjust the same. If such selectboard members are interested, a superior judge not interested, shall adjust the damages. Such adjudication shall be final between the parties. (Amended 1973, No. 249 (Adj. Sess.), § 82, eff. April 9, 1974.)
