When the New Hampshire legislature passes a law, it is published first as a chapter law. After a legislative session all the chapter laws of the session are published in an annual volume titled Laws of the State of New Hampshire. Collectively, the annual chapter laws are called session laws, though you may see the terms used interchangeably.
Session laws are arranged by chapter numbers which were assigned in sequence as the law was enacted. This consecutive arrangement makes it difficult to find all the law on a particular subject. Each individual volume of session laws has an index, but there is no index to the entire body of session laws. Statutory codes were developed in the 19th century to make finding and using statutory law easier. The New Hampshire Revised Statutes Annotated (RSA) is New Hampshire's most recent statutory code, created in 1955.
Not all statutes passed by the legislature are in the Revised Statutes Annotated. There are different types of statutes: general, private, permanent, and temporary. The Revised Statutes Annotated, like other statutory codes, contains only general and permanent statutes.
Private and temporary laws are found in the session law volumes.
A chapter law may have a preamble, a statement of purpose, or a “findings and declaration” section that won't be included in the NH RSAs so it's important to check the chapter law when compiling a legislative history.
