Section 135. Presumption of culpable mental state.-
In any prosecution for an offence under this Act which
requires a culpable mental state on the part of the accused, the court shall
presume the existence of such mental state but it shall be a defence for the
accused to prove the fact that he had no such mental state with respect to the
act charged as an offence in that prosecution.
Explanation.-For the purposes of this section,-
(i) the expression "culpable mental state"
includes intention, motive, knowledge of a fact, and belief in, or reason to
believe, a fact;
(ii) a fact is said to be proved only when the court
believes it to exist beyond reasonable doubt and not merely when its existence
is established by a preponderance of probability.
