§ 135.75 Coercion; defense.

In any prosecution for coercion committed by instilling in the victim
a fear that he or another person would be charged with a crime, it is an
affirmative defense that the defendant reasonably believed the
threatened charge to be true and that his sole purpose was to compel or
induce the victim to take reasonable action to make good the wrong which
was the subject of such threatened charge.
