Sutherland Asbill & Brennan LLP, rebranded to the abbreviated name of Sutherland, is an AmLaw 100 American law firm. Founded in 1924 by William Sutherland and Elbert Tuttle as Sutherland & Tuttle, the firm originally achieved national prominence on tax issues. Sutherlands practice extends throughout the United States and worldwide, and is focused on seven major practice areas: corporate, energy and environmental, financial services, intellectual property, litigation, real estate, and tax. As of January 2011, the firm had approximately 422 attorneys. Founded in 1924 by William Sutherland, who had earlier served as a law clerk to U.S. Supreme Court Justice Brandeis, and Elbert Tuttle, who later became the Chief Judge on the U.S. Court of Appeals for the 5th Circuit and a recipient of the Presidential Medal of Freedom, the firm of Sutherland & Tuttle first established a national reputation in the tax field. In the ensuing years, the firm has also developed prominent practices in corporate, energy, financial services, intellectual property, litigation and real estate. During the early years, Sutherland strengthened its tax practice by mastering the intricacies of the New Deal legislation. The firm became adept in this area through the work of Joseph Brennan, who became a partner in 1933. Now known as Sutherland, Tuttle & Brennan, the firm also took on many landmark pro bono matters in this era, including the landmark 1938 right-to-counsel case of Johnson v. Zerbst, one of the most oft-cited cases in the 20th century. The firm opened an office in Washington, DC in 1937, and this office grew apace after World War II when William Sutherland relocated to the city. The tandem development of the Atlanta and Washington offices gave the firm the distinction of being one of the first national law firms.
