Parole and mandatory supervision laws in Texas have a long history of revisions, amendments, and re-codifications. Currently, these statutes are located in Government Code chapter 508. Prior to 1997, though, these statutes were codified first as Code of Criminal Procedure Art. 42.12 then as Code of Criminal Procedure Art. 42.18.
We compiled PDF documents that show the language of these statutes as of any specific date between 1966 and 2004. (After 2004, please visit the Statutes by Date section of the Texas Constitution and Statutes online.) We also list each session law that has amended the parole and mandatory supervision statutes since January 1, 1966.
