    HISTORICAL ANALYSIS IN IOWA STATUTORY
                           CONSTRUCTION


                             Karen   L. Wallace*

                                   ABSTRACT
      This Article provides an empirical analysis of Iowa Supreme Court decisions
from  2014-2024   that employ  legislative history and other types of historical
consideration in interpreting Iowa statutes. It updates a prior analysis that considered
the years 2004-2013  and finds that the Iowa Supreme Court continues to consider
historical sources when interpreting ambiguous statutes and has cited several new
types of legislative history sources it did not use in the original study period. The
Article also identifies a current debate on these practices, with two sitting justices
questioning the validity of consulting legislative history for statutory interpretation.
The  Article concludes with research recommendations to help readers understand
Iowa  statutes and an appendix providing all the citations to Iowa legislative history
the study found.
