On 18 September 2019, the Court of Justice of the European Union ruled on the respective scopes of the Brussels Ibis and the (old) Insolvency Régulations in Skarb Pánstwa Rzeczpospolitej Polskiej (case C‑47/18).
The Court held:
1. Article 1(2)(b) of Regulation (EU) No 1215/2012 of the European Parliament and of the Council of 12 December 2012 on jurisdiction and the recognition and enforcement of judgments in civil and commercial matters must be interpreted as meaning that an action for a declaration of the existence of claims for the purposes of their registration in the context of insolvency proceedings, such as that at issue in the main proceedings, is excluded from the scope of that regulation.
2. Article 29(1) of Regulation No 1215/2012 must be interpreted as not applying, even by analogy, to an action such as that in the main proceedings which is excluded from the scope of that regulation but falls within the scope of Regulation No 1346/2000.
3. Article 41 of Council Regulation (EC) No 1346/2000 of 29 May 2000 on the law applicable to contractual obligations must be interpreted as meaning that a creditor may, in the context of insolvency proceedings, lodge a claim without formally indicating the date on which it arose, where the law of the Member State within the territory of which those proceedings were opened does not impose an obligation to state that date and where that date may, without particular difficulty, be inferred from the supporting documents referred to in Article 41 of that regulation, which it is for the competent authority responsible for the verification of claims to determine.
