I am not sure if it is a trend, but recently several nations have raised dubious legal claims  over territory that was ceded away by treaty.  For instance, Spain has zero legal claim to Gibraltar, as far as I can tell, unless the 1713 Treaty of Utrecht ceding it to Britain "in perpetuity" can be wished away.  Bolivia has zero...

The Second Circuit's decision in Balintulo v. Daimler* (already discussed at length by John Bellinger at Lawfare) is one of the first major U.S.court opinions to apply the Supreme Court's decision in Kiobel.  It is pretty much a complete smackdown of the ATS plaintiffs, and for any hopes they might have that the Kiobel decision's bar on extraterritoriality for ATS suits...
