Questione giuridica chiave
Whether the waiver clause in the 7 September 2004 decision was a revocable waiver of benefits or an integral part of a settlement.
Decisione estratta
It was an intrinsic part of the settlement and could not be detached and revoked as a standalone waiver.
Motivazione estratta
The 2004 decision resulted from mutual concessions on the expected effect of surgery and the level of benefits. The waiver clause was the sine qua non of that transaction and therefore not an independent waiver under Art. 23 LPGA.
