Act 328 of 1931


750.157a Conspiracy to commit offense or legal act in illegal manner; penalty.

Sec. 157a.

    Any person who conspires together with 1 or more persons to commit an offense prohibited by law, or to commit a legal act in an illegal manner is guilty of the crime of conspiracy punishable as provided herein:

    (a) Except as provided in paragraphs (b), (c) and (d) if commission of the offense prohibited by law is punishable by imprisonment for 1 year or more, the person convicted under this section shall be punished by a penalty equal to that which could be imposed if he had been convicted of committing the crime he conspired to commit and in the discretion of the court an additional penalty of a fine of $10,000.00 may be imposed.

    (b) Any person convicted of conspiring to violate any provision of this act relative to illegal gambling or wagering or any other acts or ordinances relative to illegal gambling or wagering shall be punished by imprisonment in the state prison for not more than 5 years or by a fine of not more than $10,000.00, or both such fine and imprisonment.

    (c) If commission of the offense prohibited by law is punishable by imprisonment for less than 1 year, except as provided in paragraph (b), the person convicted under this section shall be imprisoned for not more than 1 year nor fined more than $1,000.00, or both such fine and imprisonment.

    (d) Any person convicted of conspiring to commit a legal act in an illegal manner shall be punished by imprisonment in the state prison for not more than 5 years or by a fine of not more than $10,000.00, or both such fine and imprisonment in the discretion of the court.

History: Add. 1966, Act 296, Eff. Mar. 10, 1967

Constitutionality Notes:

    A mandatory life sentence imposed for conspiracy to commit first-degree murder, even if nonparolable, is not so excessive as to constitute cruel and unusual punishment; nor does it violate the Equal Protection Clauses of the Michigan and United States Constitutions. People v Fernandez, 427 Mich 321; 398 NW2d 311 (1986).
