39When assignment ceases to operate

39 When assignment ceases to operate (1) If a certified debt is discharged, or the judgment that resulted in a debt certificate being issued in respect of the certified debt is set aside by a court, any assignment effected by operation of this Division in connection with that debt ceases to operate. (2) If only part of the certified debt is discharged, the assignment effected in respect of that part of the certified debt ceases to operate. (3) This section does not affect any payment or dealing that is made by a principal in good faith before the principal receives notice, and sufficient evidence of, the discharge or setting aside of the debt. To the extent necessary to give effect to that payment or dealing, the assignment effected by operation of this Division is taken to continue in force. If a principal makes a payment to a claimant (as required by section 35), instead of paying the respondent, without knowing that the debt owed to the claimant has been discharged by the respondent, this section protects the principal from being required by the respondent to make payment to the respondent.
