AG Szpunar delivered on 14 January 2020 its opinion in case C‑641/18 (LG v Rina SpA, Ente Registro Italiano Navale), which is about Brussels I :

« Article 1(1) of Council Regulation (EC) No 44/2001 […] is to be interpreted as meaning that an action for damages brought against private-law bodies in respect of classification and certification activities carried out by those bodies as delegates of a third State, on behalf of that State and in its interests, falls within the concept of ‘civil and commercial matters’ within the meaning of that provision.

The principle of customary international law concerning the jurisdictional immunity of States does not preclude the application of Regulation No 44/2001 in proceedings relating to such an action”.
