The Mannheim Registry Court had refused to register a former Swiss company, which mutated into an S.a.r.L. in Luxembourg, in the German commercial register on the grounds that it had originally been founded in Switzerland and therefore not in a member state of the European Union. However, the Karlsruhe Higher Regional Court fortunately agrees with the view that even "transit companies" are deemed to have been founded in the EU and must therefore be registered in Germany (Karlsruhe Higher Regional Court of 24 April 2024, 1 W 40/23 Wx).
The background to the double relocation is that Luxembourg allows companies from countries that are neither part of the EU nor the European Economic Area to move to the country.
