Harry Elwood Warren Scholar and Professor of Law, Boston University Law School
Jack Beermann’s scholarship focuses on two areas: civil rights litigation and administrative law. He is an authority on the circumstances under which state and local officials, and local governments, should be held liable for their constitutional violations. “What particularly fascinates me is studying the values underlying our public law system and how social movements and history have affected those values,” he says.
Professor Beermann has authored or co-authored four books on administrative law, including a widely-used casebook and the Emanuel Law Outline on the subject. He has also written extensively on the degree to which federal courts should defer to the legal determinations of federal agencies, on the problem of midnight rulemaking, in which outgoing administrations promulgate dozens of regulations at the end of their administrations and on the legal aspects of the funding crisis facing public employee pension funds in the United States.
His articles have appeared in prominent American journals such as the Stanford Law Review, UCLA Law Review, Duke Law Journal, and Boston University Law Review, and in foreign law journals including Germany’s Rechtstheorie and China’s Administrative Law Review. Recent articles include “The Public Pension Crisis” in the Washington & Lee Law Review, “Congressional Administration” in the San Diego Law Review and the “Constitutional Law of Presidential Transition” in the North Carolina Law Review. In 1998, he co-authored an article that examined civil rights violations in the popular television drama NYPD Blue and in 1993 he wrote “The Supreme Court’s Narrow View on Civil Rights” for the prestigious Supreme Court Review.
Before joining the Boston University faculty in 1984, Professor Beermann clerked for Judge Richard Cudahy of the United States Court of Appeals for the Seventh Circuit. In 2017, he was appointed as a public member of the Administrative Conference of the United States. In 2008, 2011 and 2014 he was visiting professor at Harvard Law School and in 1997, he was distinguished visiting professor at DePaul Law School. In 2004, 2005 and 2007, he taught at the Interdisciplinary Center in Herzliya, Israel, and in 2002, he taught at the China University of Political Science and Law in Beijing. He has lectured in Israel, Germany, Australia, Morocco, Portugal and Canada. At BU Law, Professor Beermann teaches administrative law, civil rights litigation, and constitutional law.

She also prevailed against the EEOC in a case that the employment defense bar called “good news for employers across the country.” And in “the most important patent case in modern history” according to patent law experts, her argument before the Court was credited for “pick[ing] up two votes that pundits thought unreachable.”

Mrs. Ho has argued a series of high stakes, landmark cases on behalf of the business community before the U.S. Supreme Court. National Law Journal called her a “Veteran SCOTUS Advocate” in the “upper echelons of Supreme Court practice.” Law360 named her a “Supreme Court Star” and “one of the nation’s preeminent appellate lawyers.” And EmpiricalSCOTUS.com ranked her among “the most successful attorneys that currently practice before the Court.” Mrs. Ho once argued two significant business cases before the Court within the span of 21 days—including a “significant ruling for employers” that “paved a new path for companies paying millions of dollars in retiree health care benefits” (Law360), as well as a landmark administrative law dispute in which “several justices agreed with Ho’s contention that SCOTUS should revisit and overrule its own precedent” (Law360). She also prevailed against the EEOC in a case that the employment defense bar called “good news for employers across the country.” And in “the most important patent case in modern history” according to patent law experts, her argument before the Court was credited for “pick[ing] up two votes that pundits thought unreachable.”
She has appeared before every federal court of appeals in the country, including en banc arguments before the Fourth and Sixth Circuits. She has successfully represented business clients in every circuit, including the First (Pruco Life Insurance Company), Second (Swiss Federation; Rite Aid), Third (Johnson & Johnson), Fourth (Genex Services), Fifth (United Space Alliance LLC; Elliott Co.; MERSCORP; 24 Hour Fitness USA, Inc.; Stream Energy; Health Management Systems), Sixth (Deutsche Bank; American Airlines; M&G Polymers), Seventh (Expedia), Eighth (Cotter), Ninth (Boeing; JP Morgan Chase Bank), Tenth (Mitchell International), Eleventh (AstraZeneca), D.C. (FedEx), and Federal (Repros Therapeutics) Circuits.
In addition, Mrs. Ho regularly appears in state appellate courts across the country. She has argued numerous cases in the Texas Supreme Court, Texas appellate courts in Dallas, Houston, San Antonio, Corpus Christi, and Eastland, and state appellate courts in Arizona, Michigan, New York, Ohio, Oklahoma, and West Virginia, prevailing on behalf of Ford Motor Company, PepsiCo, International Paper, Tenet, GameStop, Deutsche Bank, and Unit.

Bush, Counselor to Attorney General John Ashcroft, and law clerk to Justice Sandra Day O’Connor of the U.S. Supreme Court and Judge Jacques L. Wiener Jr. of the U.S. Court of Appeals for the Fifth Circuit.
Her record of public service also includes appointments to various boards and commissions. Among the most notable are her election as a member of the Administrative Conference of the United States, a trustee of the United States Supreme Court Historical Society, and a trustee of the Texas Supreme Court Historical Society. She is also vice chair of the Federal Judicial Evaluation Committee, appointed by U.S. Senators John Cornyn and Ted Cruz to evaluate potential appointments of all federal judges and U.S. Attorneys in Texas, and has previously served on the U.S. Magistrate Judge Merit Selection Panel for the Northern District of Texas.

Lecturer in Economics, Stanford Graduate School of Business
I spent more than 14 years in economic policy roles advising senior elected officials, including for a time as the senior White House economic advisor to President George W. Bush. As Deputy Director and then Director of the White House National Economic Council, I coordinated economic policy design and implementation for the President.
The last thirteen months of my time in the White House were by far the most intense, helping advise President Bush on his Administration’s response to the financial crisis.
In addition to that work, here are some of the major Presidential policies that I helped design, enact, and implement:
Before working for President Bush I was an aide to Senate Majority Leader Trent Lott (R-MS). I helped him enact economic legislation (and block other legislation) including the 1997 Balanced Budget Act and President Bush’s 2001 tax cut. I came to Senator Lott’s staff from the Senate Budget Committee staff, where I spent two years as a health and retirement economist working for the Chairman, Senator Pete Domenici (R-NM).
I’ve got a Master’s in Public Policy from Harvard’s Kennedy School and a B.A.S. in Math and Political Science from Stanford.
