Section 1. The General Assembly, in order to insure continuity of State and local governmental operations in periods of emergency resulting from enemy attack, terrorism, disease, accident, or other natural or man-made disaster, shall have the power and the immediate duty (1) to provide for prompt and temporary succession to the powers and duties of public offices whose immediate succession is not otherwise provided for by this Constitution, of whatever nature and whether filled by election or appointment, the incumbents of which may become unavailable for carrying on the powers and duties of such offices, and (2) to adopt such other measures as may be necessary and proper for insuring the continuity of governmental operations. In the exercise of the powers conferred by this section, the General Assembly shall in all respects conform to the requirements of this Constitution except to the extent that in the judgment of the General Assembly to do so would be impracticable or would cause undue delay.
