Professor Dubin completed his A.B. from Dartmouth College in three years with distinction in government and J.D. from N.Y.U. Law School where he was an Arthur Garfield Hays Civil Rights-Civil Liberties Fellow. He served as law clerk to U.S. District Judge John L. Kane Jr.; assistant counsel for the NAACP Legal Defense and Educational Fund, Inc.; director of litigation and staff attorney for the Harlem Neighborhood Office of the Legal Aid Society, Civil Division; assistant attorney general in the Civil Rights Bureau of the N.Y. State Attorney General's Office; and Marvin M. Karpatkin Fellow on the American Civil Liberties Union’s national staff. Immediately prior to joining the Rutgers–Newark law faculty in 1999, he was a professor of law and director of clinical programs at St. Mary’s Law School, where he received the faculty award for teaching excellence, founded and directed the first in-house clinic, and served as the founding faculty advisor to the Black Allied Law Students Association and coach of the Frederick Douglass Moot Court Team.
In 2002, the National Equal Justice Library selected his article, “Torquemada Meets Kafka: The Misapplication of the Issue Exhaustion Doctrine to Inquisitorial Administrative Proceedings” (Columbia Law Review), for the Edgar and Jean Cahn Award as one of the 20th century’s most outstanding articles about equal justice for lower-income persons. The U.S. Supreme Court twice cited this article in the text of its decisive plurality opinion in Sims v. Apfel, 530 U.S. 103 (2000), a case in which Professor Dubin served as the Petitioner's co-counsel, principal drafter of the Petitioner’s main brief, and principal strategist of the petitioner’s position in this successful appeal. In 2019, the U.S. Supreme Court cited two more of Professor Dubin's writings in Biestek v. Berryhill, 139 S. Ct. 1148 (2019): his law review article, Overcoming Gridlock: Campbell after a Quarter-Century and Bureaucratically Rational Gap-Filling in Mass Justice Adjudication in the Social Security Administration's Disability Programs, 62 Admin. L. Rev. 937 (2010), in the text of the dissenting opinion; and the 2019 edition of his co-authored treatise, Social Security Disability Law and Procedure In Federal Court (co-authored with Carolyn A. Kubitschek, Thomson Reuters Publishing Co., 2019), in the text of the majority opinion.
A much earlier article, “From Junkyards to Gentrification: Explicating a Right to Protective Zoning in Low-Income Communities of Color” (Minnesota Law Review), was peer-reviewed and selected for inclusion in an anthology issue of Clark-Boardman’s Land Use and Environment Law Review as one of the five best land-use articles of that year.
Professor Dubin received the 2003 Haywood Burns/Shanara Gilbert Award from the Northeast Regional People of Color Legal Scholarship Conference for "scholarship and action that advances the legal, social and economic position of people of color;" the 2007 Stanley Van Ness Leadership Award in Public Interest Law from the New Jersey Public Interest Law Center/New Jersey Appleseed for career contributions in public interest law; the 2010 Oliver Randolph Award from the Garden State Bar Association for contributions to the civil rights of African Americans; the 2014 Eileen P. Sweeney Award from the National Organization of Social Security Claimants' Representatives for "outstanding service to improve the quality and availability of advocacy for social security claimants and to improve the social security adjudicative process;" and the 2014 Clinical Legal Education Association's Award for outstanding contributions and accomplishments on behalf of clinical legal education and clinical law teachers. In 2016, he was elected into the National Academy of Social Insurance , a nonprofit organization comprised of “the nation’s leading experts on social insurance and social welfare policy” who have made "distinguished and continuing achievements in the field.”
He has been chair of the AALS Poverty Law Section, a member of the ABA Commission on Homelessness and Poverty, and a board member of the Clinical Law Review, Clinical Legal Education Association, National Center on Law and Economic Justice, New Jersey Institute for Social Justice, and the San Antonio Fair Housing Council.
He has taught in a Civil Justice Clinic for low income and homeless clients and supervised clinical student work and led clinic litigation in over ten successful social security disability cases in the U.S. Courts of Appeals for the Third and Fifth Circuits, a successful appeal in the U.S. Supreme Court, major parts of a multi-decade housing discrimination and public housing preservation class action in U.S. District Court in Newark, and over 200 evidentiary hearings for clinic clients. He has also taught several classroom courses including Administrative Law, Constitutional Law, Civil Rights Law, Poverty Law, and Social Security Law and seminars in Welfare Law and World Hunger and International Law.
