The Uniform Post-Conviction Procedure Act was promulgated by the National Conference of Commissioners on Uniform State Law (NCCUSL) in 1955. The act was revised in 1966 and amended in 1980. This act provides a single post-conviction review as part of the criminal process. This act is now regarded by the NCCUSL as a model act, instead of a uniform act. So it may also be known as the Model Post-Conviction Procedure Act.
