Question juridique clé
Whether the appellant still had a valid power of attorney giving him a right to bank information
Solution extraite
No. Any power of attorney had been revoked, at the latest by the bank's communication of 24 January 2006, so no authority existed when the action was filed.
Motifs extraits
Revocation of a power of attorney can be implied; once the bank communicated the revocation, the internal authority ended and the bank again owed secrecy. The court left open whether the authority had already ended earlier upon closure of the account, because in any event no authority existed by the filing date.
