defences now put forth, namely, that the cheques were issued only as security, that the Complainant did not fulfil its investment obligations, and that part-payments had already been made, turn on disputed questions of fact that must be established through evidence. The reliance on Dashrathbhai Trikambhai Patel is misplaced. That decision arose in an appeal where both the Trial Court and the High Court had upheld an acquittal, after full trial. The findings on the question of legally enforceable debt were rendered on the basis of evidence adduced by parties. At this pre-trial stage, such factual questions cannot be adjudicated upon while considering a quashing petition. 8. It is well-settled that once issuance and dishonour of the cheque are admitted or not in dispute, the statutory presumptions under Sections 118(a) and 139 of the NI Act operate in favour of the complainant. Whether these presumptions stand rebutted is a matter to be tested at trial. A bare assertion that the cheque was given as security or that the liability stood reduced does not, in itself, furnish a basis to quash proceedings at the threshold.
