According to Portuguese law,(1) arbitration cannot apply to disputes concerning non-disposable rights, and any arbitration agreement to that effect is invalid. Nonetheless, the Lisbon Court of Appeal recently held that in such cases the invalidity of an arbitration agreement relates only to those rights which are absolutely non-disposable, not to those which are relatively non-disposable, such as rights that involve an economic interest - these are arbitrable.(2)


The plaintiff brought proceedings against the defendants, seeking indemnity for damages and commission arising out of an agency contract. The defendants objected, claiming that an arbitration clause had been breached. The court found this to be true and dismissed the proceedings against all defendants.

The plaintiff appealed, stating that the arbitration agreement was invalid. The plaintiff maintained that not all disputes can be resolved by arbitration, as the law states that disputes concerning non-disposable rights are not arbitrable. In this case, one of the claims in the plaintiff's petition referred to indemnity for damages arising out of the termination of an agency contract, which it regarded as a non-disposable (and therefore non-arbitrable) right. It was argued that, as a result, the arbitration agreement should be deemed invalid and unenforceable.


The Lisbon Court of Appeal confirmed the first instance decision, stating that only rights which are absolutely non-disposable result in the arbitral convention being null and void. As a result, disputes are non-arbitrable only where the parties have no freedom whatsoever to establish or dispose of their rights.

The appellate court correctly observed that the concept of non-disposable rights must be determined on a case-by-case basis.(3) In this case, the right to be indemnified for damages caused by the termination of the agency contract was a right with an economic interest. This made it a disposable right, which could therefore be submitted to arbitration.(4)


The Lisbon Court of Appeal decision is well reasoned and entirely accurate. As in many other jurisdictions,(5) arbitration cannot apply to disputes concerning non-disposable rights. Nevertheless, as was correctly noted, the legislative project for a new Arbitration Law, which is being debated in Parliament, establishes a different criterion for arbitrability: disputes are arbitrable if they are related to economic interests.(6)

The question of the best criterion for determining arbitrability opens up a further issue for discussion; however, on the basis of existing law the appellate court's interpretation on non-disposable rights was correct.
