§ 210.30 Perjury; no defense.
It is no defense to a prosecution for perjury that:
1. The defendant was not competent to make the false statement
alleged; or
2. The defendant mistakenly believed the false statement to be
immaterial; or
3. The oath was administered or taken in an irregular manner or that
the authority or jurisdiction of the attesting officer who administered
the oath was defective, if such defect was excusable under any statute
or rule of law.
