The General Assembly declares: (1) that recent technological developments make possible an enemy attack of unprecedented destructiveness, which may result in the death or inability to act of a large proportion of the membership of the General Assembly; (2) that to conform in time of attack to existing legal requirements pertaining to the General Assembly would be impracticable, would admit of undue delay, and would jeopardize continuity of operation of a legally constituted General Assembly; and (3) that it is therefore necessary to adopt special provisions, as hereinafter set out, for the effective operation of the General Assembly.
