Legal disputes

The Argentine State is, again, being sued by a "fondo buitre" for 390 million US$ for the illegal nationalization of Aerolíneas Argentinas. Marsans, a Spanish corporation, sold its litigation rights to Burford Capital, which later transferred them to the Belgian fund Titan Consortium. In 2021, Titan filed a petition in a D.C. court to recognize and enforce the ICSID award. Burford had invested $12.8 million to fund the arbitration. Cristina Fernández, then President of Argentina, committed the error of taking over foreign assets, but American Judges accept cases like that. I think that Fidel Castro's nationalization of everything in Cuba will, some time in the future, be litigated, and the assets returned to the inheritors. Or to the fondos buitre that may have bought the rights of litigation. These processes may continue for centuries. 

The Pleitos colombinos (1508–1536). Those capitulations granted Columbus and his heirs, in perpetuity, the offices of Admiral of the Ocean Sea and Viceroy and Governor of any lands he discovered, plus a tenth of the Crown's revenues from them. Once the scale of the Americas became clear, the Crown had no intention of handing a single family hereditary control over a continent. After Columbus died in 1506, his legitimate son and heir, Diego Colón, sued the Crown in 1508 to enforce those rights. The Council of the Indies finally awarded the inheritance in 1608 to Nuño Colón de Portugal, a descendant through a female line. The Columbus inheritance was in litigation for most of a century. The line of the Dukes of Veragua continues to this day.
