Ministero delle Finanze v IN.CO.GE.'90 Srl and others Joined Cases C-10/97 to C-22/97 [1998] ECR I-6307
Facts
Italian companies sought repayment of registration charges levied under national provisions incompatible with an EU directive concerning indirect taxes on raising capital. They obtained orders for repayment, which the Ministry of Finance challenged. A dispute arose about which domestic court and procedural rules should govern recovery. The referring court considered whether disapplying the offending tax legislation meant that the legal relationship lost its fiscal character and instead became an ordinary civil claim. It asked the Court of Justice how the supremacy of EU law affected the status of the national provisions and the repayment proceedings.
Legal Issue
Did incompatibility with EU law automatically nullify national legislation or reclassify a tax repayment claim as civil, and what constraints governed domestic recovery procedures?
Held
The Court explained that the duty to disapply incompatible national law did not itself render that law non-existent. A Member State was in principle required to repay charges collected contrary to EU law, but domestic law determined the relevant procedure and legal classification. Those rules had to respect equivalence and effectiveness: they could not be less favourable than rules for comparable domestic claims or make EU rights virtually impossible or excessively difficult to exercise. The incompatibility therefore did not automatically strip the charge of its fiscal character. The national court had to secure repayment within the appropriate domestic framework, subject to those EU limits, rather than invent a compulsory civil-law classification.
⭐ Legal Principle
Supremacy requires disapplication of conflicting national law where necessary, not automatic erasure of that law from the legal system. Recovery of unlawful charges follows national procedural rules subject to equivalence and effectiveness; classification of the relationship remains a matter for national law.
Significance
IN.CO.GE is useful for distinguishing disapplication from invalidity and for understanding national procedural autonomy. Its repayment context prevents the terminology from becoming abstract: a claimant has an EU entitlement, but still needs a workable domestic procedure. Compare Marks & Spencer on limits to retrospective repayment restrictions. Neither decision gives Member States unrestricted procedural discretion, and neither requires all EU-based tax claims to be treated as ordinary civil restitution actions.
Common exam questions about this case
Does EU supremacy automatically make conflicting legislation non-existent?
No. The court must refuse to apply the legislation where necessary to protect the applicable EU right, but EU law does not automatically erase it from the national legal system. IN.CO.GE distinguishes that disapplication duty from national questions about the legislation's formal status and the classification of relationships created under it.
Could Italy apply its special tax-repayment procedures?
In principle, yes. EU law did not require reclassification of the claim as ordinary civil restitution merely because the charge was incompatible. However, the procedures had to satisfy equivalence and effectiveness. Special rules could not disadvantage comparable EU claims or make the practical recovery of unlawful charges impossible or excessively difficult.
How is this case related to Marks & Spencer?
Both recognise that national procedures govern recovery of charges paid contrary to EU law within EU constraints. IN.CO.GE addresses classification and procedural autonomy, while Marks & Spencer examines a retrospective limitation change. Together they show that recognising a repayment right and assessing the lawful machinery for enforcing it are separate steps.
