Legal materials can fall into two different categories: (1) Primary and (2) Secondary. Statutes are a primary legal source. Statutes are laws of general force and effect enacted by a legislature and signed by an executive. Statutes are fluid in nature. Once enacted, the legislature may continually return to the statute and change (amend) it.
Both state and federal statutes follow the same basic steps going from bill to session law form. Statutes are first enacted by the legislature. Then they are signed by the executive. They may first be published as a slip law. These slip laws are then published as session laws.
A session law is the chronological publication of the laws passed by a jurisdiction. You may hear session laws referred to as acts as well. Session laws may include both public (laws of a general nature) and private (laws that apply to a specific person or group or that are temporary in nature) laws. Each session law is assigned a number.
In the Federal system, the first part of the number is the congress that passed the law.
Pub. L. No. 107-56
Here in the Federal example, the 107 refers to the 107th Congress. The second part of the number is the number of the law passed. So, here in the example, the 56 refers to it being the 56th law passed by the 107th Congress.
State session laws will vary in their numbering system. Some use chapters. Kentucky uses the year and chapter number. Indiana numbers its post-1982 public laws by first assigning the law a number and then the year of the law. So in the Indiana example, the numbering scheme refers to it being the 33rd law passed in the year 2008. Ohio uses the bill number.
KY: 1998 Ky. Acts ch. 21, § 1
IN: Pub. L. 33-2008
OH: Am. H.B. No. 268, 126 Ohio Laws 730.
Session laws of a permanent and general nature are codified to the statutory code of the jurisdiction. A code is a subject compilation of these laws of a permanent and general nature. The advantages of using a code for research include the fact that codes collate original laws with later amendments, they bring all laws on the same subject together, and they eliminate repealed, superseded, or expired laws.
For more information on the process of a bill becoming law, please consult our legislative history guide: http://guides.libraries.uc.edu/Federal_Legislative_History.
A code is a subject arrangement of the laws of a jurisdiction. There are official and unofficial codes. A code may be annotated (containing editorial enhancements to help with research or interpretation) or unannotated. The advantages of using a code for research include:
In addition to the statutes, many codes contain constitutions and court rules.
Session laws usually have official and unofficial publications.
