Judgment of the Court of Justice in the case SEB bankas.
1. Article 184 of Council Directive 2006/112/EC must be interpreted as meaning that the obligation to adjust undue value added tax (VAT) deductions set down in that article also applies to cases where the initial deduction could not be made lawfully because the transaction giving rise to that deduction was exempt from VAT. By contrast, Articles 187 to 189 of Directive 2006/112 must be interpreted as meaning that the mechanism for the adjustment of undue VAT deductions provided for in those articles is not applicable in such cases, in particular in a situation such as that at issue in the main proceedings, where the initial VAT deduction was unjustified as it concerned a VAT-exempt transaction relating to the supply of land.
2. Article 186 of Directive 2006/112 must be interpreted as meaning that, in cases where the initial deduction of VAT could not be made lawfully, it is for the Member States to determine the date on which the obligation to adjust the undue VAT deduction arises and the time period for which that adjustment must be made, in accordance with the principles of EU law, in particular the principles of legal certainty and legitimate expectations. It is for the national court to determine whether, in cases such as that at issue in the main proceedings, those principles have been respected.
