Sec. 62.  CONTINUITY OF STATE AND LOCAL GOVERNMENTAL OPERATIONS FOLLOWING ENEMY ATTACK.  (a) The Legislature, in order to insure continuity of state and local governmental operations in periods of emergency resulting from disasters caused by enemy attack, shall have the power and the immediate duty to provide for prompt and temporary succession to the powers and duties of public offices, 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.  Provided, however, that Article I of the Constitution of Texas, known as the "Bill of Rights" shall not be in any manner affected, amended, impaired, suspended, repealed or suspended hereby.
(b)  When such a period of emergency or the immediate threat of enemy attack exists, the Legislature may suspend procedural rules imposed by this Constitution that relate to:
(1)  the order of business of the Legislature;
(2)  the percentage of each house of the Legislature necessary to constitute a quorum;
(3)  the requirement that a bill must be read on three days in each house before it has the force of law;
(4)  the requirement that a bill must be referred to and reported from committee before its consideration; and
(5)  the date on which laws passed by the Legislature take effect.
(c)  When such a period of emergency or the immediate threat of enemy attack exists, the Governor, after consulting with the Lieutenant Governor and the Speaker of the House of Representatives, may suspend the constitutional requirement that the Legislature hold its sessions in Austin, the seat of government.  When this requirement has been suspended, the Governor shall determine a place other than Austin at which the Legislature will hold its sessions during such period of emergency or immediate threat of enemy attack.  The Governor shall notify the Lieutenant Governor and the Speaker of the House of Representatives of the place and time at which the Legislature will meet.  The Governor may take security precautions, consistent with the state of emergency, in determining the extent to which that information may be released.
(d)  To suspend the constitutional rules specified by Subsection (b) of this section, the Governor must issue a proclamation and the House of Representatives and the Senate must concur in the proclamation as provided by this section.
(e)  The Governor's proclamation must declare that a period of emergency resulting from disasters caused by enemy attack exists, or that the immediate threat of enemy attack exists, and that suspension of constitutional rules relating to legislative procedure is necessary to assure continuity of state government.  The proclamation must specify the period, not to exceed two years, during which the constitutional rules specified by Subsection (b) of this section are suspended.
(f)  The House of Representatives and the Senate, by concurrent resolution approved by the majority of the members present, must concur in the Governor's proclamation.  A resolution of the House of Representatives and the Senate concurring in the Governor's proclamation suspends the constitutional rules specified by Subsection (b) of this section for the period of time specified by the Governor's proclamation.
(g)  The constitutional rules specified by Subsection (b) of this section may not be suspended for more than two years under a single proclamation.  A suspension may be renewed, however, if the Governor issues another proclamation as provided by Subsection (e) of this section and the House of Representatives and the Senate, by concurrent resolution, concur in that proclamation.
