Haynes and Boone represented AT&T against claims of breach of contract, fraud and quantum meruit brought by a German investment bank (GCG). GCG alleged that AT&T orally promised to pay GCG a 2 percent success fee (approximately $780 million) if A&T successfully acquired T-Mobile. The trial court granted summary judgment for AT&T on the pleadings, dismissing all of GCG?s claims. The Dallas Court of Appeals affirmed the take-nothing judgment in favor of AT&T.
