Two lawyers have spent much of the past decade defending Argentina in front of the same U.S. judge in dozens of lawsuits arising from the South American country’s 2001 default on $95 billion in sovereign debt.

Jonathan Blackman and Carmine Boccuzzi, partners at New York’s Cleary Gottlieb Steen & Hamilton, have represented Argentina in litigation that began in 2002. The two share a history with U.S. District Judge Thomas Griesa, the New York jurist who has presided over the fate of billions of dollars of Argentine debt over the same period.
