The Grand Chamber delivered on 17 May 2022 its judgment in case C‑869/19 (L v Unicaja Banco SA, formerly Banco de Caja España de Inversiones, Salamanca y Soria SAU), which is about Directive 93/13/EEC on Unfair terms in consumer contracts and national rules of procedure:

“Article 6(1) of Council Directive 93/13/EEC of 5 April 1993 on unfair terms in consumer contracts must be interpreted as precluding the application of principles of national judicial procedure, under which a national court, hearing an appeal against a judgment temporally limiting the repayment of sums wrongly paid by the consumer under a term declared to be unfair, cannot raise of its own motion a ground relating to the infringement of that provision and order the repayment of those sums in full, where the failure of the consumer concerned to challenge that temporal limitation cannot be attributed to his or her complete inaction”.
