Iowa Constitution Art. III, § 35. Senators and representatives--number and districts

The general assembly shall in 1971 and in each year immediately following the United States decennial census determine the number of senators and representatives to be elected to the general assembly and establish senatorial and representative districts. The general assembly shall complete the apportionment prior to September 1 of the year so required. If the apportionment fails to become law prior to September 15 of such year, the supreme court shall cause the state to be apportioned into senatorial and representative districts to comply with the requirements of the constitution prior to December 31 of such year. The reapportioning authority shall, where necessary in establishing senatorial districts, shorten the term of any senator prior to completion of the term. Any senator whose term is so terminated shall not be compensated for the uncompleted part of the term.
