Cornell Law professor Michael C. Dorf considers how the recent treatment of tennis player Naomi Osaka by the professional tennis establishment highlights key aspects of disability law. Professor Dorf argues that while reasonable people can disagree in many cases about what constitutes the “essence” of a sport for purposes of the Americans with Disabilities Act (ADA), no one can plausibly argue that speaking to reporters at a press conference is in any way essential to playing tennis.

Cornell Law professor Michael C. Dorf considers whether and how the U.S. Supreme Court next term might eliminate or substantially curtail the constitutional right to abortion recognized in Roe v. Wade. Professor Dorf describes the jurisprudence after that decision and argues that a decision that upholds the Mississippi law while purporting to forestall deciding the ultimate fate of Roe would be brazenly dishonest—albeit somewhat more likely than a clear overruling of Roe.

Cornell Law professor Michael C. Dorf comments on last week’s announcement by the Facebook Oversight Board with its verdict regarding the company’s treatment of former President Donald Trump’s suspended account. Professor Dorf argues that the Board’s ruling makes sense in many respects, but makes two mutually exclusive demands of Facebook: clear rules for the sake of predictability and at the same time, flexibility for moderators to consider the individual context of a situation.

Cornell Law professor Michael C. Dorf comments on the recent news that President Joseph Biden is using the word “genocide” to describe the Turkish regime’s murder of roughly 1.5 million Armenians during and after World War I. Professor Dorf explains why language matters in the context of genocide, torture, eugenics, taxes, and Humpty Dumpty.

Cornell Law professor Michael C. Dorf comments on a recent concurrence by Justice Clarence Thomas in a case in which the Court vacated as moot a federal appeals court ruling that the president cannot block users’ access to his Twitter account. Professor Dorf explains why Justice Thomas’s reasoning is deeply flawed, but he points out that Justice Thomas’s conclusion that the First Amendment might permit Congress to forbid Twitter from moderating content on its site finds unlikely support in arguments historically put forth by progressive politicians and scholars. In their view, very large private actors who exercise power over people’s lives comparable to and sometimes even exceeding that of government should be subject to the same sorts of norms that the Constitution applies to the government.

Cornell Law professor Michael C. Dorf comments on a brief filed by Donald Trump’s former lawyer Sidney Powell in a defamation lawsuit brought by Dominion Voting Systems. Professor Dorf argues that Powell’s motion to dismiss the case should fail, but he notes that the argument presented in her brief is more subtle than is generally acknowledged.

Cornell law professor Michael C. Dorf responds to three broad-based objections by Republican opponents to the American Rescue Plan Act of 2021: (1) that the already-recovering economy doesn’t need stimulus; (2) that many of the Act’s provisions have nothing to do with COVID-19; and (3) that there will be waste, fraud, and abuse. Professor Dorf explains why these objections ring hollow and argues that while the Act is not perfect legislation and will likely face challenges in implementation, it is a much better option than anything Republicans were offering.

Cornell law professor Michael C. Dorf describes the ostensibly complex legal issues presented in United States v. Arthrex, Inc., in which the U.S. Supreme Court heard argument earlier this week, and explains how those issues reflect an ideological divide as to other, more accessible matters. Professor Dorf argues that although many conservatives would like to dismantle the modern administrative state, our complex modern society all but requires these government agencies, so conservatives instead seek to make them politically accountable through a Senate-confirmed officer answerable to the president, furthering the so-called unitary-executive theory of Article II.

Cornell law professor Michael C. Dorf comments on the U.S. Supreme Court’s decision last week to reject an emergency application from the State of Alabama to lift a stay on the execution of Willie B. Smith III. Professor Dorf observes the Court’s unusual alignment of votes in the decision and argues that, particularly as reflected by the recent COVID-19 decisions, the liberal and conservative Justices have essentially swapped places from the seminal 1990 case Employment Division v. Smith, which established that the First Amendment does not guarantee a right to exceptions from neutral laws of general applicability.

Cornell law professor Michael C. Dorf explains why Trump v. Sierra Club, a challenge to President Trump’s border wall currently pending before the U.S. Supreme Court, exemplifies the needless complexity of federal court gatekeeping law. Professor Dorf lists the various legal doctrines that restrict access to the federal courts and argues that their number and complexity tend to undercut, rather than serve, justice.

Cornell law professor Michael C. Dorf comments on the willingness of Americans to believe lies and misinformation, pointing to confirmation bias and social media bubbles as playing key roles in this problem. Professor Dorf argues that we must render Trumpism beyond the pale, in part by shunning those who spread lies and minimizing opportunities for them to spread dangerous misinformation and incite riots.

Cornell law professor Michael C. Dorf describes what is at stake on Wednesday, January 6, when Congress meets in joint session to confirm Joe Biden’s election as President. Professor Dorf explains why, although Trump apparently lacks the majority necessary to invalidate a duly chose electoral slate, the stakes are still very high.

Cornell law professor Michael C. Dorf explains the legal concepts of ripeness and laches, which pertain to the timing of filing a lawsuit, and argues that in the context of election lawsuits, it is far better for courts to relax ripeness rules and risk unnecessary adjudications than to discard the doctrine of laches and risk widespread disenfranchisement and the undermining of confidence in fair elections.

Cornell law professor Michael C. Dorf argues Trump’s actions during his final months are different from those of past presidents, and particularly dangerous. As Dorf explains, Trump is aiming to do damage for its own sake, whereas other lame-duck presidents have at least sought to advance policy aims in pursuit of some conception of the common good.

In light of recent news that Pfizer and Moderna have apparently created safe and effective vaccines against COVID-19, Cornell law professor Michael C. Dorf considers whether the government can mandate vaccination for people who lack a valid medical reason not to get vaccinated. Dorf briefly addresses issues of federalism and religious objections to vaccination and then addresses the question whether mandatory vaccination might be inconsistent with a right to abortion.

Cornell law professor Michael C. Dorf comments on the third challenge to the Affordable Care Act (ACA) that has made it before the U.S. Supreme Court, and considers how the case will play in the upcoming Georgia runoff elections. Dorf argues that absent a dramatic and highly unusual development—like a Supreme Court decision rejecting the ACA challenge in the next few weeks—that should help the Democratic candidates in Georgia’s runoff elections.

Cornell law professor Michael C. Dorf explores several options that Democratic presidential candidate Joe Biden should consider if he wins the election and fulfills his proposal of convening a bipartisan commission of constitutional scholars to study and recommend court reforms. Dorf discusses the benefits and limitations of each option and describes how Congress and a President Biden could implement meaningful court reform that could withstand review by the Supreme Court itself.

Cornell law professor Michael C. Dorf comments on a statement by Justice Clarence Thomas (joined by Justice Samuel Alito) gratuitously expressing his hostility to the Court’s same-sex marriage decision in Obergefell v. Hodges and his sympathy for Kim Davis, a county clerk in Kentucky who refused to issue marriage licenses to same-sex couples even after the Supreme Court’s decision. Although Justice Thomas characterizes Davis and those like her as people who “refus[e] to alter their religious beliefs in the wake of prevailing orthodoxy,” Dorf points out that no one asked Davis to alter her religious beliefs. Rather, the lawsuit against her contends that she must provide services to the public in accordance with their constitutional rights, whatever her religious beliefs.

UF Levin College of Law professor and economist Neil H. Buchanan, Cornell Law professor Michael C. Dorf, and Harvard Law professor emeritus Laurence H. Tribe explain why President Trump’s plan to win the election through a forced decision by the U.S. House of Representatives relies on an incorrect reading of the plain text of the Twelfth Amendment of the Constitution. The authors argue, even in a best-case scenario for Trump, in which the electoral votes of Pennsylvania are thrown out, Biden would still win with a majority of the resulting electoral votes and the House would simply not have the legal authority to vote on an election that had already been decided.

Cornell law professor Michael C. Dorf comments on last night’s presidential debate between President Trump and former Vice President Biden. Dorf observes that Trump’s repeated violations of the agreed-upon rules of the debate; his outrageous substantive comments refusing to condemn white supremacy (and instead naming a specific white supremacist group) and declining to say he would accept the outcome of the election; and his callous response to Biden’s mention of Biden’s deceased son Beau should alert any yet unaware Americans to the fact that Trump has no sense of decency.
