Appreciation of the title of this piece of course depends on how one as an individual likes Bauhaus, or not. A November 2017 European Parliament Study on looted works of art and cultural goods is something of a treasure trove for public and private international lawyers alike. The study looks at substantive law on the issue in the Member States (not the cup of tea for this blog) but kicks off with good overview of the challenges of sovereign immunity; applicable law (particularly with respect to choice of law; with inspiration being sought in the Belgian Private International Law Act, Article 90 (lex furti as a principle – the place from which the object was removed, but with corrections), and the issue of the application of foreign public international law by the courts.
Parliament is quite active on this issue. In May 2016 it had already published a study with more focus on the specific issue of art looted in times of conflict, and alternatives to court litigation but nevertheless with a short forray into conflict of laws (and reference to one or two interesting national cases).
Together the two studies are a good exercise for the conflicts mind.
Geert.
