Florida Statutes Title XLVI. Crimes § 837.02. Perjury in official proceedings

(1) Except as provided in subsection (2), whoever makes a false statement, which he or she does not believe to be true, under oath in an official proceeding in regard to any material matter, commits a felony of the third degree, punishable as provided in s. 775.082, s. 775.083, or s. 775.084.

(2) Whoever makes a false statement, which he or she does not believe to be true, under oath in an official proceeding that relates to the prosecution of a capital felony, commits a felony of the second degree, punishable as provided in s. 775.082, s. 775.083, or s. 775.084.

(3) Knowledge of the materiality of the statement is not an element of the crime of perjury under subsection (1) or subsection (2), and the defendant's mistaken belief that the statement was not material is not a defense.
