This section applies where compensation payments in respect of the same accident, injury or disease fall (or apart from the recoupment provisions would fall) to be made to or in respect of the same victim by two or more compensators.

Where this section applies, any two or more of those compensators may give the Department notice that they are collaborators in respect of compensation payments in respect of that victim and that accident, injury or disease.

Where such a notice is given and any of the collaborators makes a relevant payment in connection with such a compensation payment, each of the other collaborators shall be treated as if the aggregate amount of relevant payments specified in his certificate of total benefit, as in force at the time of that relevant payment, or in a fresh certificate which does not purport to reflect the payment, were increased by the amount of that payment.
