Section 143A of the Negotiable Instruments (NI) Act, concerning interim compensation, came into effect on 1st September 2018. While the Act received Presidential assent on 2nd August 2018, its applicability is prospective from the date of the official gazette notification, not retrospectively. Therefore, a complaint filed under Section 138 of the NI Act on 10th August 2018 cannot claim interim compensation under Section 143A.
