§ 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.
