Most of the advocates in cross get evidence against their clients since no advance prepration and expereince.
Any NI 138 case can be demolished in cross alone., I have given no of examples of cross on this site at many threads by which any complainant can be clean bold in cross alone.
You have messed up your case since 1) admitted you had given cheque 2) your bank has admitted that the cheque was bounced from your account and 3) you have given opportunity to the complainant to show source of funds.
IT SHOULD HAVE BEEN OTHER WAY ROUND..IT WAS THE DUTY OF THE COMPLAINANT TO PROVE WHICH YOU HAVE ALLOWED HIM TO SHOW IN CROSS AND HENCE COME ON RECORD.
Any court will ask why the cheque was given having your signature and from your account which was bounced far want of funds.
Money lending and availabilty of funds these two items were solid defense which should have been got from the mouth of the complainant which is missed and now citafions have no meaning.
EVEN AT THIS LATE STAGE FIND SOME LOCUNA IN THE PROCEEDING AND FILE A REVISION SO THAT YOU WILL GET TIME TO SCOUT OTHER DEFENSE.
Please also do not sent me PM since I prefer to reply publicly for benefit of all and even let others to join by their inputs.
