The Legislature 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 Legislature;
(2) That to conform in time of attack to existing legal requirements pertaining to the Legislature would be impracticable, would admit of undue delay and would jeopardize continuity of operation of a legally constituted Legislature; and
(3) That it is therefore necessary to adopt special provisions as set out in this chapter for the effective operation of the Legislature.
