“If an AI system can make an improvement, if we can demonstrate and verify and validate that it's working better, then this is how we hold it accountable and what we should be aspiring for,” says Warren Center faculty affiliate Cary Coglianese.

This is a new era,” Prof. Cary Coglianese (@cary-coglianese.bsky.social) tells WBUR’s On Point, as AI use in gov’t grows from 150 to 3,000+ cases. “Humans design & use these systems — and they must remain accountable.” https://penncareylaw.news/4oTsNFj

As we approach our 20th anniversary, we look back at an early contribution to Regulation & Governance, including this first editorial by the John Braithwaite, Cary Coglianese & David Levi-Faur that asked: 'Can regulation and governance make a difference?' onlinelibrary.wiley.com/doi/10.1111/...

After the Supreme Court tamps down on nationwide injunctions, future pathways and questions still remain. Warren Center faculty affiliate Cary Coglianese writes about "Judicial Remedies After CASA." www.theregreview.org/2025/08/11/c...

In a recent essay, Cary Coglianese of Penn Carey Law contends that effective regulation demands ongoing vigilance and responsiveness rather than reliance on written codes alone. www.theregreview.org/2025/08/19/m...

In an op-ed for The Regulatory Review, coauthored by Matthew Lee Wiener, Professor Cary Coglianese examines the Supreme Court’s decision in Trump v CASA eliminating nationwide injunctions, and he explores the legal questions and pathways that remain for litigants challenging national policies.

In a recent essay, Cary Coglianese of the University of Pennsylvania Carey Law School argues that regulation must be understood as a verb—an ongoing process of vigilance and adaptation—rather than a static set of written rules. www.theregreview.org/2025/08/19/m...

As The Regulatory Review wraps up its series on the Supreme Court’s latest term, my colleague, Matt Wiener, and I analyze one of the most significant decisions of the year: Trump v. CASA, which closed the door on federal courts’ use of national injunctions. www.theregreview.org/2025/08/11/c...

This is an excellent interview with my coauthor @cary-coglianese.bsky.social, where he talks among other things about our new paper on Loper Bright. Cary explains very clearly why we question the Court's claim to have overruled Chevron. Our paper is posted here: papers.ssrn.com/abstract=537...

All agencies need a degree of autonomy to operate in a manner that advances public welfare--and autonomy matters crucially for those agencies whose mission is to gather evidence and report data, whether or not those agencies are formally independent as a legal matter. papers.ssrn.com/sol3/papers....

Loper Bright's Disingenuity, with @cary-coglianese.bsky.social, is forthcoming in the University of Pennsylvania Law Review. We argue that the majority opinion in Loper Bright is empty and internally contradictory. It is an assertion of power rather than reason. papers.ssrn.com/abstract=537...

Professor @cary-coglianese.bsky.social’s essay in Science draws on a recent report he coauthored with Cynthia Giles, entitled “Third-Party Auditing Cannot Guarantee Carbon Offset Credibility,” which is available online in the Penn Carey Law SSRN working paper series. papers.ssrn.com/sol3/papers....

New report on climate offset integrity, accompanying an editorial in Science: “Auditing’s weaknesses are too often ignored when advocates of more expansive offset markets tout auditors as a guarantor of credit integrity.” www.science.org/doi/10.1126/...

This huge loss is hard to fathom because David Gergen always seemed larger than life—whether on television or in person. His many years of public service and leadership—across party lines, too—leave a remarkable legacy. Deep condolences to his family.

“The likelihood of deepfakes in the courtrooms is only increasing with each passing day,” says Warren Center faculty affiliate Cary Coglianese. “This is definitely a serious concern.” www.bostonglobe.com/...

Offsets: "Given the high planetary stakes in carbon policy choices being made now, it is past time to recognize that third-party auditors selected and paid by the audited organizations are not the bulwark for credit integrity they are claimed to be." @cary-coglianese.bsky.social and Cynthia Giles.

New paper: “On Leashing (and Unleashing) AI Innovation,” w/ Colton Crum. We propose an alternative way of conceiving of AI regulation that allows innovation to flourish while still, importantly, assuring it remains under attentive human oversight. We call it regulating by “leashes.” bit.ly/46rsI5C

Regulatory “guardrails” are unrealistic when AI is moving so fast along multiple paths that can scarcely be mapped let alone constrained by fixed, prescriptive rules.
