Pennsylvania v. New Jersey, 426 U.S. 660 (1976) (holding that Pennsylvania could not sue New Jersey in the Supreme Court on behalf of Pennsylvania’s citizens with respect to a New Jersey transportation benefits tax imposed on income of Pennsylvania citizens derived from New Jersey because Pennsylvania’s suit represented nothing more than an aggregation of private lawsuits that those Pennsylvania citizens could have brought against New Jersey for taxes withheld from them, and no sovereign or quasi-sovereign interests of Pennsylvania were implicated).
Principality of Monaco v. Mississippi, 292 U.S. 313 (1934) (holding, and unjustly depriving us of a monumental spectacle, that Monaco couldn’t sue Mississippi in the Supreme Court without Mississippi’s consent to enforce pre-Civil War bonds issued by various Mississippi entities, which had been in default for around 90 years, and which had been donated to the Monaco consulate in Paris by certain unknown troublemakers who “had been advised that there was no basis upon which they could maintain a suit against Mississippi on the bonds, but that ‘such a suit could only be maintained by a foreign government or one of the United States’”).
