The Boards of Appeal shall be responsible for deciding on appeals from decisions taken
pursuant to Articles 160 to 164.
The decisions of the Boards of Appeal shall be taken by three members, at least two of
whom are legally qualified. In certain specific cases, decisions shall be taken by the Grand
Board chaired by the President of the Boards of Appeal or by a single member, who shall
be legally qualified.
In order to determine the special cases which fall under the jurisdiction of the Grand
Board, account should be taken of the legal difficulty or the importance of the case or of
special circumstances which justify it. Such cases may be referred to the Grand Board:
(a) by the authority of the Boards of Appeal referred to in Article 166(4)(a); or
(b) by the Board handling the case.
The Grand Board shall also be responsible for giving reasoned opinions on questions of
law referred to it by the Executive Director pursuant to Article 157(4)(1).
To determine which specific cases fall under the authority of a single member, account
should be taken of the lack of difficulty of the legal or factual matters raised, the limited
importance of the individual case or the absence of other specific circumstances. The
decision to confer a case on one member in the cases referred to shall be adopted by the
Board handling the case.
