41. Application of this Act to pending cases.-(1) Notwithstanding anything contained in sub-section (2) of section 1, all cases pending before the courts or under investigation at the commencement of this Act shall be disposed of in accordance with the provisions of the principal Act as amended by this Act and accordingly, any person found guilty of any offence punishable under the principal Act, as it stood immediately before such commencement, shall be liable for a punishment which is lesser than the punishment for which he is otherwise liable at the date of the commission of such offence:

Provided that nothing in this section shall apply to cases pending in appeal.

(2) For the removal of doubts, it is hereby declared that no act or omission on the part of any person shall be punishable as an offence which would not have been so punishable if this Act has not come into force.
