Portuguese law allows an endorser to use the principal debtor's defenses except for payment.

The Tribunal da Relação do Porto confirmed the lower court's decision dismissing the endorser's appeal regarding the principal debtor's defenses. The endorser argued for the application of the principal debtor's exceptions, while the opposing party contended that payment was the sole exception permitted. The court ruled that under Portuguese law, an endorser cannot invoke the principal debtor's defenses except for the defense of payment.
