We represented Mobil Oil in overturning a $3 million default judgment in Venezuela (that had been affirmed by the Venezuelan Supreme Court) based on Mobil’s alleged failure to diligently prosecute an oil exploration effort on land where the plaintiff held a royalty interest, but where there had never been shown to be any commercial quantities of oil. After an investigation into the facts in Venezuela, and proceedings in five courts (three in Virginia and two in New York), we obtained a judgment declaring the Venezuelan judgment null and void and requiring the plaintiff to pay Mobil’s costs.
