Black's Law Dictionary defines legislative history as "the background and events leading to the enactment of a statute, including hearings, committee reports, and floor debates."  So in order to understand and create a legislative history, one must understand the process by which laws, or statutes, are created.

    How does a bill become a law (statute) in Oklahoma?    All laws originate as bills.  A legislator introduces a bill in the House Chamber or the Senate Chamber of the Oklahoma Legislature.  A summary of the bill is read aloud to the chamber.  The bill is then sent to a specific committee in the chamber for study and recommendations, and is then returned to the chamber for a vote to pass or a vote for further study by the committee.  If the bill is passed by the chamber of origin, it is then sent to the other chamber.  At this stage of its development, the bill is "engrossed".

   An engrossed bill may be amended by the other chamber, and then it may go to a conference committee composed of members of both chambers.  The conference committee may also make amendments to the bill.   A bill may not receive any amendments.  Whether passed in its original form or in its amended form, a bill that passes both chambers is called "enrolled".  Enrolled bills go to the governor for signature.  The bill becomes a law when the governor signs the bill. 

   The law is called a session law before it is placed into the statory code.  Laws passed during a legislative session are published in the Oklahoma Session Laws, which are chronologically arranged.  Session laws are then codified, placed into the statutory code, in a subject arrangement.  The Oklahoma Statutes contain all the laws in force in the state of Oklahoma as of the time of publication.
