Résumé Omnilex

The Administrative Court considered a claim for restitution of tax alleged to have been paid without cause. It held that a restitution action based on the general rule against undue enrichment depends on whether the payment was made without a valid legal basis at that time. Because the tax assessment had not been challenged and had become final, it provided a valid cause for the payment. The restitution claim was therefore dismissed.

Regeste Omnilex

LPA art. 4 al. 3; restitution of undue payment in tax matters requires absence of a valid legal basis at the time of payment. A tax payment made pursuant to an uncontested and final assessment is not undue, since the final assessment itself constitutes valid causa solvendi; an action in repetition of the undue is therefore excluded where the assessment has entered into force unchallenged.

Question juridique clé

Whether an action for restitution of undue payment is admissible when the tax was paid pursuant to a final, uncontested assessment.

Solution extraite

No. A final, uncontested tax assessment constitutes a valid cause for payment, so the payment is not undue.

Motifs extraits

The admissibility of restitution under the general principle of undue enrichment depends on whether the payment lacked a valid legal basis at the time it was made. Here, the tax assessment had entered into force without challenge, therefore it supplied a valid cause.
