The 66th Texas Legislature enacted the Texas Property Tax Code into law in 1979 (Senate Bill No. 621, 1979 Tex. Laws. p. 2217, ch. 841, Sec. 1). The historical notes following some sections in this publication refer to amendments to the Code in subsequent legislative sessions. If no amending history appears, that particular section has remained unchanged since its enactment in 1979.
The most recent statutory changes are cited by bill number, legislative session and effective date. Earlier legislative history is cited to the Texas Session Laws as published by the Texas Secretary of State.
Section 6(b) of Senate Bill 621 provided that "all other general, local, and special laws in conflict with this Act are repealed to the extent of the conflict, and the failure expressly to repeal or amend any law in conflict with this Act is not evidence of a legislative intent that the law not be repealed."
