In this context, Spurs peg their hope on what the rules state; NSL's clause 23:4:1 states that a party may launch an appeal or bring a review before the SAFA Arbitration Tribunal where the Dispute Resolution Chamber has determined a dispute.
Further, the clause says that rulings or awards of the Dispute Resolution Chamber are only subject to appeal or review before the SAFA Arbitration Tribunal.
Under the NSL clauses, parties’ fundamental procedural rights are guaranteed, including the right to be heard, the right to equal treatment, the right to examine the Dispute Resolution Chamber file, the right to have evidence taken, and the right to receive a reasoned decision.
These particular provisions of the law are what Spurs are pinning their hope on after losing at the PSL DRC.
