Questão jurídica principal
Whether the repayment claim itself could still be challenged as time-barred or lapsed.
Decisão extraída
No; the repayment order was not appealed and was final, so the repayment claim was no longer within the scope of dispute.
Fundamentação extraída
Only the waiver of repayment was before the Court; objections against the underlying repayment claim were inadmissible.
