Bill tracking is the process used to follow the path that proposed legislation has followed once introduced in the Legislature. It can be used to track current legislation to see if it is near passage or rejection. It can also be used retrospectively on older proposed legislation.

Slip Laws
The first issuance of an enacted law passed by the Arizona Legislature is a slip law. Current slip laws are available on the website of the
Arizona Legislature

Sessions Laws
At the end of each legislative session, slip laws are consolidated and arranged chronologically into a permanent set of bound volumes called session lawsSession laws are an official publication of the Secretary of State’s office and are issued annually at the end of a l
egislative session. 

In addition to enacted legislation, Arizona session laws contain:

  • Veto messages written by the Governor
  • Election results for the year
  • Listing of federal and state elected officials for Arizona
  • The Governor’s Message to the legislators at the start of the legislative session
  • Listings of memorials and proclamations
Each session law is assigned a chapter number.  At the beginning of each chapter is the title of the bill and the Senate or House bill number. Additions to the law are usually indicated by an underline, while repeals or removal of language are indicated by a strike through. Session laws lack subject arrangement and are not cumulative, making it difficult to locate laws on a particular subject.
The session laws from 1989 (39th Legislature) to date are on the Arizona State Legislature website. The site default is to the current legislative session. For another session, click on “change session” in the navigation bar at the top. 

Session Laws 1912-1996 are available on the
Arizona Memory Project website.  Arizona Session Laws are also available on HeinOnline (1864-present, on campus or ASURITE), on the University of Arizona Daniel F. Craccchiolo Law Library website (1864-1909), and in print at KFA 2425 .A212 (1912-present).


The Arizona Revised Statutes Annotated, published by West/Thomson Reuters, is the official statutory code for the State of Arizona. When issued in 1956, an enacting clause designated this set as the positive law (binding authoritative text of law) for Arizona.  

The annotated code contains both the full-text of every statute as well as annotations, which include statutory notes, historical notes, and citations to law reviews, legal forms, legal encyclopedias, treatises, and West Digest key numbers. Attorney General opinions and cross-references to the Arizona Administrative Code, the United States Code or, Uniform Laws may also be listed.  In addition, notes of decisions are provided in the annotated code, which provide brief synopses of cases decided on that point of law.

In addition to enacted legislation, the Arizona Revised Statutes Annotated contains:

  • Annotated Rules of Court
  • Constitutions - Arizona and United States
  • Declaration of Independence
  • Treaties - Treaty of Guadeloupe, Hidalgo and Gadsden Treaty
  • Proclamation of Admission/Admission of the State of Arizona
  • State Anthems
  • Constitutional Convention
  • Election Ordinance no.2
  • Enabling Act

The current version of the Arizona Revised Statutes Annotated in print is located in the main reading room of the Law Library. Superseded annotated codes and historical Arizona territorial codes are also available in the Law Library. In addition, the Arizona Revised Statutes are available through a number of electronic resources:

Types of Proposed Legislation
Bills – proposed legislation introduced by either house of the legislature. A bill creates new laws or amends or repeals existing law.
Memorials – a legislative measure containing a request or proposal to a named recipient. They petition a recipient to act on an issue that the Arizona Legislature does not have jurisdiction to act upon itself. Memorials are merely requests and have no official standing or effect. Memorials may be presented for consideration in either one house (simple) or both houses (concurrent).
Resolutions – a declaration of legislative opinion, will, intent, or resolve in matters within the legislature's legal purview. There are three types of resolutions:

  • Simple Resolutions are considered only by one house and may express an opinion, appoint a committee, commemorate the death of a prominent public figure, or request the return of a bill from the other house in the legislature. Simple resolutions are not signed by the Governor.
  • Concurrent Resolutions are processed through both houses of the legislature, but are not signed by the governor. They may provide for the submittal of a referendum to voters, initiate legislative action to amend either the U.S. or Arizona Constitution, or express regret for the death of a prominent public figure.
  • Joint Resolutions are used for temporary measures having the effect of law. They cannot be used to amend the U.S. or Arizona Constitutions. They are passed through both houses and signed by the Governor.

Proposed Legislation Numbering
Each type of proposed legislation receives its own numbering and is numbered consecutively in the order they are introduced. Proposed legislation originating in the Senate begins numbering at 1001, while legislation originating in the House of Representatives begins numbering at 2001. At the start of each Legislature (which is two years in length), the numbering begins again at 1001 (Senate) and 2001 (House of Representatives). Proposed legislation not passed by the time the legislative session ends must be reintroduced in the new Legislature to be considered. It will receive a new number. Therefore, it is useful to know either the year or the Legislature in which the proposed legislation was introduced.

Bill Versions
There may be several versions of proposed legislation. Either the House or Senate (or both) may pass amendments that change the text of the bill, resolution or memorial. When amended, it is either reprinted with the amending language incorporated into it or the amendment(s) may be printed separately.
