679:7 Jurisdiction; Court Appeals. –
I. In matters within its authority the board shall have concurrent, appellate jurisdiction with the superior court. An election by any party to bring an action before the board shall be deemed a waiver of any right to bring an action in the superior court, but shall not abrogate any party's right to appeal decisions of the board to the supreme court; as such, the board shall retain jurisdiction of any matter originally brought before it. At any time during an appeal to the board, if the board determines that it does not have jurisdiction to hear the appeal, the appellant shall have 30 days to file an appeal with the superior court.
II. In an appeal of a local decision on housing or housing development, any claim that is within the board's authority under RSA 679:5 and that has previously been or is subsequently included in an appeal in superior court by another party to the decision or by any other aggrieved or injured party who can demonstrate legal standing to appeal pursuant to RSA 677:4 or RSA 677:15 shall automatically be stayed by the court to provide the party with standing the opportunity to intervene in the matter before the board. If intervenor status is granted, the stay of the court action regarding those claims shall continue during the pendency of the appeal to the board. After the board has decided the appeal, the court shall dismiss the matter before it to the extent the matter has been resolved by the board. Any claim included in an appeal to superior court that is not within the board's authority shall not be subject to automatic stay by the court.
