(720 ILCS 5/32‑2) (from Ch. 38, par. 32‑2)
    Sec. 32‑2. Perjury.
    (a) A person commits perjury when, under oath or affirmation, in a proceeding or in any other matter where by law such oath or affirmation is required, he makes a false statement, material to the issue or point in question, which he does not believe to be true.
    (b) Proof of Falsity.
    An indictment or information for perjury alleging that the offender, under oath, has made contradictory statements, material to the issue or point in question, in the same or in different proceedings, where such oath or affirmation is required, need not specify which statement is false. At the trial, the prosecution need not establish which statement is false.
    (c) Admission of Falsity.
    Where the contradictory statements are made in the same continuous trial, an admission by the offender in that same continuous trial of the falsity of a contradictory statement shall bar prosecution therefor under any provisions of this Code.
    (d) A person shall be exempt from prosecution under subsection (a) of this Section if he is a peace officer who uses a false or fictitious name in the enforcement of the criminal laws, and such use is approved in writing as provided in Section 10‑1 of "The Liquor Control Act of 1934", as amended, Section 5 of "An Act in relation to the use of an assumed name in the conduct or transaction of business in this State", approved July 17, 1941, as amended, or Section 2605‑200 of the Department of State Police Law (20 ILCS 2605/2605‑200). However, this exemption shall not apply to testimony in judicial proceedings where the identity of the peace officer is material to the issue, and he is ordered by the court to disclose his identity.
    (e) Sentence.
    Perjury is a Class 3 felony.
