42.3  Timetable for preparation of plan.
  1.  a.  Not later than April 1 of each year ending in one, the legislative services agency shall deliver to the secretary of the senate and the chief clerk of the house of representatives identical bills embodying a plan of legislative and congressional districting prepared in accordance with section 42.4. It is the intent of this chapter that the general assembly shall bring the bill to a vote in either the senate or the house of representatives expeditiously, but not less than three days after the report of the commission required by section 42.6 is received and made available to the members of the general assembly, under a procedure or rule permitting no amendments except those of a purely corrective nature. It is further the intent of this chapter that if the bill is approved by the first house in which it is considered, it shall expeditiously be brought to a vote in the second house under a similar procedure or rule. If the bill embodying the plan submitted by the legislative services agency under this subsection fails to be approved by a constitutional majority in either the senate or the house of representatives, the secretary of the senate or the chief clerk of the house, as the case may be, shall at once, but in no event later than seven days after the date the bill failed to be approved, transmit to the legislative services agency information which the senate or house may direct by resolution regarding reasons why the plan was not approved.
  b.  However, if the population data for legislative districting which the United States census bureau is required to provide this state under Pub. L. No. 94-171 and, if used by the legislative services agency, the corresponding topologically integrated geographic encoding and referencing data file for that population data are not available to the legislative services agency on or before February 15 of the year ending in one, the dates set forth in paragraph “a” shall be extended by a number of days equal to the number of days after February 15 of the year ending in one that the federal census population data and the topologically integrated geographic encoding and referencing data file for legislative districting become available.
  2.  If the bill embodying the plan submitted by the legislative services agency under subsection 1 fails to be enacted, the legislative services agency shall prepare a bill embodying a second plan of legislative and congressional districting. The bill shall be prepared in accordance with section 42.4, and, insofar as it is possible to do so within the requirements of section 42.4, with the reasons cited by the senate or house of representatives by resolution, or the governor by veto message, for the failure to approve the plan. If a second plan is required under this subsection, the bill embodying it shall be delivered to the secretary of the senate and the chief clerk of the house of representatives not later than thirty-five days after the date of the vote by which the senate or the house of representatives fails to approve the bill submitted under subsection 1, or the date the governor vetoes or fails to approve the bill. If it is necessary to submit a bill under this subsection, the bill shall be brought to a vote not less than seven days after the bill is submitted and made available to the members of the general assembly, under a procedure or rule permitting no amendments except those of a purely corrective nature. It is further the intent of this chapter that if the bill is approved by the first house in which it is considered, it shall expeditiously be brought to a vote in the second house under a similar procedure or rule. If the bill embodying the plan submitted by the legislative services agency under this subsection fails to be approved by a constitutional majority in either the senate or the house of representatives, the secretary of the senate or the chief clerk of the house, as the case may be, shall transmit to the legislative services agency in the same manner as described in subsection 1, information which the senate or house may direct by resolution regarding reasons why the plan was not approved.
  3.  If the bill embodying the plan submitted by the legislative services agency under subsection 2 fails to be enacted, the same procedure as prescribed by subsection 2 shall be followed. If a third plan is required under this subsection, the bill embodying it shall be delivered to the secretary of the senate and the chief clerk of the house of representatives not later than thirty-five days after the date of the vote by which the senate or the house of representatives fails to approve the bill submitted under subsection 2, or the date the governor vetoes or fails to approve the bill. The legislative services agency shall submit a bill under this subsection sufficiently in advance of September 1 of the year ending in one to permit the general assembly to consider the plan prior to that date. If it is necessary to submit a bill under this subsection, the bill shall be brought to a vote within the same time period after its delivery to the secretary of the senate and the chief clerk of the house of representatives as is prescribed for the bill submitted under subsection 2, but shall be subject to amendment in the same manner as other bills.
