Arizona Primary Legal Materials

A quick guide to Arizona government documents and State court decisions.


Statutes are laws passed by the Arizona Legislature.  Once a bill becomes law, it is first published as a "slip law".  Slip laws are eventually organized by chapter and chronology, and are then published in volumes known as "session laws" (all the laws passed during that session of the Legislature).  Session laws are then organized by subject/chapter into the codified, Arizona Revised Statutes (A.R.S.).  The A.R.S. contains the text of the final law and, if annotated, historical and statutory notes as well as citations to secondary sources.

Note, sessions are statutorily defined periods in which the Arizona Legislature meets (Art. IV of the Arizona Constitution).  Sessions begin on the second Monday of the year.
