Restructuring & Insolvency analysis: The European Court of Justice (ECJ) held in SML Maschinengesellschaft mbH v AK (SML) (case no. C-43/25) that German equitable subordination rules cannot be circumvented in cross-border insolvency proceedings by selecting a foreign law as applicable law for shareholder loans. The ECJ ruled that Article 13 of Council Regulation (EC) 1346/2000 (now Article 16 Regulation (EU) 2015/848) cannot be invoked by a shareholder to block an insolvency administrator’s recovery claims if those claims aim to uphold the ranking of claims in insolvency as defined by the insolvency law of the state where proceedings were opened. The decision underlines the protective nature of German insolvency law. Therefore, shareholders, and in certain circumstances also lenders, need to carefully structure their financing in German-based entities.
