Crimes: perjury; requirements for crime of perjury; modify. Amends sec. 9, ch. VIIA of 1927 PA 175 (MCL 767A.9).

This bill amends Michigan's criminal procedure code to clarify the requirements for proving perjury and to modify penalties for false statements made under oath. It specifies that an individual is guilty of perjury if they knowingly make a materially false statement during an investigation, with penalties ranging from up to 15 years in prison to life imprisonment if the investigation involves a crime punishable by life. Additionally, the bill addresses the consequences for refusing to comply with investigative subpoenas, allowing courts to commute sentences for contempt if a witness appears to purge themselves of the offense. These changes directly affect individuals subject to criminal investigations and the legal process used to determine guilt for lying under oath.
