I gave a bearer cheque to a person whose name is 'X'. Now 'X' has given that bearer cheque to 'Y'. Then, 'Y' has presented that cheque over counter for encashment and it was dishonoured for 'insufficient funds'. Now, 'Y' has returned that dishonoured cheque to 'X'. And 'X' has filed a complaint under Section 138 N.I. Act against me. My question is: how can 'X' file a complaint against me because after endorsement it is only 'Y' who has locus standi to file a complaint against me? I saw a citation in support of my argument in lawmirror but now I cannot find it. I will be thankful if anybody can help me.
