Consult an annotated version of A.R.S. (print or legal subscription service). The Session Law citations appear after the text of the statute.
Note: if it says "Added" this was probably the first time this provision appeared in Arizona law. (Sometimes "Added" appears if the section has been reorganized or renumbered. If you think there may have been a prior version, consult the Research Library. We have historic A.R.S. in print.)
"Amended" means it is a change to an earlier version.
Consult each Session Law to analyze the amendments that were made.
