Advanced Legal Research: Researching Statutes, 50-State Surveys, Uniform Laws & Municipal Codes

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.
