NRS 169.235: Superseding of criminal law no bar to punishment unless specifically expressed.

The superseding of any law creating a criminal offense shall not be held to constitute a bar to the prosecution and punishment of a crime already committed, or to bar the trial and punishment of a crime where a prosecution has been already begun, for a violation of the law so superseded, unless the intention to bar such prosecution and punishment, or trial and punishment where a prosecution has been already begun is expressly declared in the superseding act.
