6. The decisions of the Commission shall be taken by the majority of votes cast. In the event of a tie the president shall have a casting vote. The vice-president shall exercise the powers of the president, in the absence or inability to act of the latter. A decision in writing, signed by all the members of the Commission, shall have the same value as a resolution adopted at a regular sitting.
