The Portuguese Supreme Court, on the basis of the doctrine of   unforeseen circumstances, created by the financial crisis, has blessed  the termination of the contract.

First,  the doctrine of unforeseen circumstances is not yet explicitly  recognised, even if the recent decisions of the High Court go in this  direction. Secondly, a swap contract could be considered as an aleatory  contract and the case law would be reluctant to apply the doctrine of  unforeseen circumstances to this kind of contracts.
