(1) A worker with a registered agreement in relation to a loss or the commutation of a right is not entitled to receive any additional compensation for the loss or commutation of the right under an award of the Magistrates Court.
(2) However, the Magistrates Court may award additional compensation if satisfied that—
(a) the agreement was obtained by fraud or undue influence; or
(b) the agreed amount of compensation was manifestly inadequate.
(3) This section does not limit an award of additional compensation for a further loss suffered after the loss to which the agreement relates.
