Jonathan H. Adler

Adler is currently a tenured professor at Case Western Reserve University (CWRU)'s School of Law where he teaches courses in environmental, regulatory, and constitutional law. He is Director of the law school's Center for Business Law & Regulation. In 2011, Adler was named the inaugural holder of the Johan Verheij Memorial Professorship at CWRU.

Adler's research and writing on the Affordable Care Act is credited with inspiring litigation that led to a Supreme Court challenge to the lawfulness of tax credits in states that failed to create their own health insurance exchanges. Professor Adler first wrote an article for a 2011 health care symposium in which he argued that the text of the Affordable Care Act did not authorize tax credits in states that refused to set up their own health insurance exchanges. At the time this did not seem like a significant observation as the Supreme Court had not yet decided NFIB v. Sebelius and it appeared that most states would voluntarily create their own exchanges. As states started to resist implementing the Affordable Care Act, Adler co-authored several pieces with Michael Cannon of the Cato Institute arguing that an IRS rule authorizing tax credits in states that did not create their own exchanges wouldbe unlawful. Adler and Cannon's arguments were controversial, and prompted significant academic response. Adler and Cannon's work also prompted several lawsuits challenging the lawfulness of the tax credits, including Halbig v. Sebelius and King v. Burwell. Newsweek proclaimed these cases could "topple ObamaCare." Adler and Cannon filed amicus briefs defending their research in several of the cases. In the end, however, the U.S. Supreme Court rejected Adler and Cannon's interpretation by a 6–3 vote in King v. Burwell. Adler's scholarship has also been relied upon in other Supreme Court cases, and was cited by Chief Justice Roberts in his City of Arlington v. FCC dissent.

Adler supported former Tennessee Senator Fred Thompson in the 2008 presidential election. In 2012, Adler headed a screening committee appointed by Ohio governor John Kasich to assist him in selecting an appointee to fill an open seat on the Ohio Supreme Court. Adler again participated in the selection process to fill an open Ohio Supreme Court seat in 2017.

Adler is a contributing editor to National Review Online and a regular contributor to "The Volokh Conspiracy", a popular legal blog founded by UCLA law professor Eugene Volokh. He blogged anonymously under the pseudonym "Juan Non-Volokh" at "The Volokh Conspiracy" until May 1, 2006.

In 2004, Adler received the Paul M. Bator Award, given annually by the Federalist Society for Law and Policy Studies to an academic under 40 for excellence in teaching, scholarship, and commitment to students. In 2007, the Case Western Reserve University Law Alumni Association awarded Adler their annual "Distinguished Teacher Award."

In 2001, Adler moved to Cleveland, Ohio, where he met his wife, Christina. He currently lives in Ohio, with his wife and two daughters.

Adler was born in Philadelphia, Pennsylvania. He graduated from Friends' Central School before attending Yale University, where he majored in History, graduating magna cum laude in May 1991 with distinction in History. After working several years at the Competitive Enterprise Institute, Adler attended law school at the George Mason University School of Law. He attended at night while continuing to work at CEI. He was the Articles Editor for the George Mason Law Review from 1998–1999. He graduated summa cum laude in May 2000 as the class valedictorian.

Adler clerked for Judge David B. Sentelle of the United States Court of Appeals for the District of Columbia Circuit. From 1991–2000, he worked at the Competitive Enterprise Institute, a free market research and advocacy group in Washington, D.C., where he directed the Institute's environmental studies program, and worked on a wide variety of environmental policy matters. Although a proponent of "free market environmentalism," Adler has also endorsed the imposition of a carbon tax and other measures to address the problem of climate change. He is also credited with helping to convince some former climate change deniers to accept the scientific evidence for global warming and the associated threat. Adler is currently one of the most cited law professors in the fields of administrative and environmental law.
