121.3. The board of directors may appoint a syndic ad hoc on the suggestion of the review committee, at the request of the syndic or, in exceptional circumstances that it must set out in the resolution of appointment, on its own initiative.
A syndic ad hoc has the rights, powers and obligations of a syndic except that he does not have authority over an assistant syndic and may not be assisted by a corresponding syndic.
The board must take steps to preserve the independence of a syndic ad hoc at all times.
