Aryeh S. Portnoy is partner in Crowell & Moring's Litigation Group and head of the firm's Hospitality Practice. Resident in the Washington, D.C. office, Aryeh joined Crowell & Moring in 1998. He focuses on complex cross-border and domestic litigation in U.S. state and federal trial and appellate courts. He has counseled and represented corporate, non-profit, and individual clients as well as foreign and domestic government agencies and officials in all phases of litigation.

Aryeh represents hospitality companies in domestic and international litigation and arbitration matters, including disputes regarding management agreements and development projects, government contracts disputes, and antitrust litigation. Aryeh's recent representations include the successful litigation of a high profile dispute on behalf of a major hotel management company regarding the development of a 1200-room luxury convention center hotel, and the successful arbitration on behalf of another major hotel management company in a multi-million dollar dispute over the applicability of a performance standard clause in a hotel management agreement. Aryeh's recent representations also include a management dispute regarding a resort in the Caribbean and a U.S. class action regarding online pricing of hotels.

Aryeh also has substantial experience representing foreign and domestic clients in international and cross-border matters. These matters range from complex international commercial disputes involving foreign sovereign entities (including central banks) to tort claims, including wrongful death actions against public and private defendants under the Federal Tort Claims Act and state common law, and lawsuits against foreign governments on behalf of victims of terrorism. Aryeh counsels clients and has litigated extensively under the Foreign Sovereign Immunities Act (FSIA) and is the co-author and editor of an annual review of litigation under the FSIA.

Aryeh's experience also includes the representation of U.S. and local government agencies and officials. He has successfully represented officials of the United States in several matters arising from the performance of their public duties, including obtaining dismissal of all claims against a former Army Brigadier General in litigation arising from the war in Iraq. He also has represented the District of Columbia Public Schools in a major class-action under the Individuals with Disabilities Education Act.

In addition to his litigation work, Aryeh also has provided compliance counseling and training to major U.S. and multinational corporations on compliance with the U.S. Foreign Corrupt Practices Act (FCPA).

Beyond these specialty areas, Aryeh has a robust general litigation practice in which Aryeh has litigated extensively on behalf of U.S. and international corporate and individual clients in civil and criminal matters in a variety of areas including commercial disputes, white collar and securities fraud litigation, false claims act and qui tam litigation, and tax litigation. Aryeh recently obtained dismissal of all counts in a securities fraud class action under the PSLRA. Aryeh's experience also includes the successful defense of the American Psychiatric Association in a major pharmaceutical class action litigation, the dismissal (and settlement) of securities fraud claims against a major financial institution as underwriter in securitized asset offerings, and the acquittal on all counts of the president of a major marine construction company who was charged with criminal violations of the Sherman Antitrust Act.

Aryeh has an active pro bono practice, in which he has handled over 35 contested custody disputes on behalf of indigent clients in the District of Columbia. In these matters, Aryeh has represented parents and grandparents seeking custody, and also has been appointed on many occasions by District of Columbia Superior Court judges as Guardian ad Litem for children in the District of Columbia neglect system. Aryeh has been recognized for his pro bono custody work by receiving the "Idealist of the Year" award from the the Washington D.C. Chapter of City Year, and the Klepper Prize for Volunteer Excellence by the Legal Aid Society of the District of Columbia. Born and raised in New York, Aryeh is a 1995 magna cum laude graduate of Columbia University, and received his law degree in 1998 from New York University School of Law.
