Environmental Experience

Monty has defended numerous cases involving alleged exposure to contamination in groundwater, soil, and air. He is a member of a national coordinating defense counsel team for an oil company in multidistrict litigation involving the gasoline additive MTBE in the U.S. District Court for the Southern District of New York. He has had significant experience in these cases, from the preparation of dispositive motions in contamination suits brought by multiple state attorneys general; to the preparation of expert witnesses, including hydrogeologists and engineers; to the preparation and defense of depositions of corporate representatives in actions filed by public-water utilities. He has represented an oil company in the U.S. District Court for the District of Arizona against CERCLA and common-law claims seeking contribution for environmental remediation costs. He has also represented companies in their negotiations with government agencies concerning environmental and property-transfer laws.

Product Liability and Civil Litigation Experience

Monty has significant experience litigating product liability and civil litigation matters in state and federal courts across the country. In Maryland state court, he has successfully helped obtain a defense verdict before a jury on behalf of an automobile manufacturer in a wrongful-death suit involving claims of a defective transmission. In a Florida federal court, he successfully helped defend an oil company against class certification in product liability litigation brought by boat owners against the oil industry for the use of ethanol in fuel. In Maryland state courts, he has represented a heavy-machinery manufacturer as local counsel in suits involving allegedly defective engines. In a D.C. federal court, he has led the representation of a global information-technology company in a suit brought by plaintiffs claiming catastrophic injuries from an allegedly defective electronic device.

In addition to his product liability and civil litigation experience, Monty’s practice has included such diverse matters as a London-based arbitration of a contract dispute between international brokerage firms and the pro bono representation of children as a guardian ad litem in D.C. Superior Court.

He has also published several articles on environmental and civil litigation matters, from an analysis of global-warming litigation via the Supreme Court’s decision in AEP v. Connecticut to an examination of court decisions since Bell Atlantic v. Twombly and Ashcroft v. Iqbal regarding federal pleading standards.

Public Sector Experience

Monty has been active in his community, in particular serving as chair of the Redevelopment Authority (RDA) of Prince George’s County, MD. The RDA is the principal development and redevelopment agency in Maryland’s second largest jurisdiction. Its mission is to develop mixed-income housing and mixed-use development in the county’s urban communities and transit centers.

Since becoming chair in 2012, the RDA has selected more than a half-dozen development partners for projects with a total development cost of over $500 million and has closed on more than 750 loans worth more than $8 million for down-payment and closing-cost assistance to first-time homebuyers. The RDA’s efforts have been highlighted in both print (e.g., The Washington Post) and television media (e.g., WJLA-ABC News 7 – Washington, D.C.). Likewise, Monty’s role here and work in the community have been recognized by both local and national organizations, including the Prince George’s County Social Innovation Fund, Maryland’s The Daily Record newspaper, and the national urban-affairs nonprofit Next City.

Monty previously worked as a special assistant state's attorney in Prince George's County, Maryland. He also served as a law clerk for the Honorable Patrick Michael Duffy of the U.S. District Court for the District of South Carolina. He attended the College of William and Mary Law School, where he was a notes editor for the William and Mary Law Review, a member of the William and Mary Bill of Rights Journal, and a Benjamin Rush Scholar.
