When clients face complex commercial and tax disputes, they rely on S. Starling Marshall as their advocate and counselor. Starling is a trial lawyer with over 15 years of experience who has successfully represented clients before federal and state courts, arbitration panels, and administrative tribunals. Drawing on her years of government service and private practice, she guides clients toward business-minded solutions throughout all phases of an investigation or litigation.

Starling is a partner in the Litigation and Tax groups in the firm’s New York office. In addition to representing clients in all stages of litigation, she guides clients through complex IRS audits and administrative appeals, provides tax-related advice, conducts internal investigations, and represents individuals and corporate entities in criminal tax matters.

Starling focused on complex tax shelter matters involving partnerships and penalty issues and cases in the energy industry, including cases involving Section 1603 grants for renewable energy projects and nuclear decommissioning liabilities. For her service, the DOJ awarded her the Outstanding Attorney Award (2015) and the Special Commendation for Outstanding Contribution (2013). From 2010 to 2014, Starling worked with the DOJ’s Office of Legal Policy to vet candidates for the federal judiciary.

From 2008 to 2009, Starling served as a law clerk to the Hon. Victor Marrero of the U.S. District Court for the Southern District of New York.

Her pro bono work includes serving as lead counsel with the American Civil Liberties Union’s Immigrant Rights Project and with ACLU-Utah in a Bivens action against U.S. marshals who raided a family’s home on two successive days. Starling received the New York County Lawyers Association Conspicuous Service Award for authoring a chapter in “Commercial Litigation in New York State Courts,” fifth edition, a joint venture of Thomson Reuters and the New York County Lawyers Association.
