You can send back the cheque to the Bank even if it has bounced one. Dishonour of cheque once or twice does not curtail your right to represent to get it encashed. There is no restriction regarding the number of times a cheque can be presented.
Every subsequent representation and dishonour gives rise to fresh cause of action for filing complaint. Thus, if you represent the cheque and it is dishonoured again, it turns the tables in your favour giving you additional cause of action to file a complaint under S/138 .
