Unless your Bylaws say otherwise, the Directors may chose (in advance) to adopt a separate set of Bylaws which go into effect during such an emergency. Be sure you consult your Association’s legal counsel when putting these together.
(1) How to call a meeting of the Board;
(2) Quorum requirements for the meeting; and
(3) Designation of additional or substitute Directors.
Any actions taken by the Board under these special Bylaws are just as binding as under normal circumstances, and no Director or agent of the Association may be held liable as long as actions are taken in good faith.
Don’t forget this important issue when planning your emergency response (such as evacuation routes) for the community!
