Harlan Fiske Stone Moot Court Competition

About the 2025–2026 Competition

The Harlan Fiske Stone Moot Court Competition final arguments—part of the Paul, Weiss, Rifkind, Wharton & Garrison Moot Court Program—are the culmination of a three-round elimination competition in appellate advocacy. This year, 85 students entered the competition. In the qualifying round, held during the fall semester, students briefed one of two issues on behalf of either the appellant or the appellee and presented their positions in oral arguments before panels composed of alumni practitioners and professors. On the strength of their brief and oral argument scores, 24 competitors advanced to the spring semifinal round. There, they again briefed and argued a side of the same case. 

This year’s event marks the 100th anniversary of the Harlan Fiske Stone Moot Court final oral arguments. Originally started at Columbia Law School in 1925 by the Story Inn, a chapter of the legal fraternity Phi Delta Phi, the competition is named in honor of Harlan Fiske Stone 1898, who was a member of the Story Inn while a student at the Law School. Stone became dean of Columbia Law School in 1910. He served in that capacity until 1924, when President Calvin Coolidge appointed him attorney general of the United States. He was named to the Supreme Court of the United States the following year and was elevated to chief justice in 1941.

The case this year asks whether the use of the internet to transmit iMessages is sufficient to establish that the messages traveled in interstate commerce and whether the district court erred by sentencing the appellant to a term of supervised release that included a prohibition against using the internet “as a means of expressive communication,” with limited exemptions. (Read the record.)

The final round of the competition was held on Monday, April 13, 2026. Oral arguments were delivered by four outstanding student finalists: Margaret Broihier ’27, Jason Harward ’26, Coley Hungate ’26, who won best final round brief; and Benjamin Tutt ’27, who was awarded the Lawrence S. Greenbaum Prize for best oral presentation.

  1. Whether use of the internet alone is sufficient to establish that messages traveled across state lines to satisfy the interstate commerce requirement of 18 U.S.C. § 875(c).
  2. Whether the district court erred by sentencing Defendant-Appellant to a term of supervised release that included a prohibition against using the internet “as a means of expressive communication,” with limited exemptions. 

This year’s competition involves a federal criminal case against fictional defendant Meredith Grey (“Ms. Grey”). In 2025, Ms. Grey was convicted in the Eastern District of Michigan of sending threatening messages to her neighbor, Dr. Christina Yang (“Dr. Yang”), in violation of 18 U.S.C. § 875(c). 

At the time of the alleged offense, Ms. Grey and Dr. Yang lived on the same street in the small town of Lincoln, Michigan, which had 821 residents. Ms. Grey was known within her community as an anti-vaccine activist and had participated in demonstrations against vaccinations in front of Dr. Yang’s office, a small family medicine practice in Lincoln. 

On July 13, 2024, Dr. Yang received an accusatory iMessage from Ms. Grey. iMessages are encrypted messages that can be sent from one Apple device to another and travel over the internet without requiring a cellular network. Both Ms. Grey and Dr. Yang utilized Apple iPhones and were in Lincoln at the time the July 13 message was sent and received. 

On July 28, 2024, Ms. Grey sent Dr. Yang an additional series of iMessages. Once again, the messages were transmitted over the internet, and both Dr. Yang and Ms. Grey were in Lincoln when the messages were sent and received. 

Dr. Yang ultimately reported the messages to the local police department, which forwarded the case to the Federal Bureau of Investigation. Ms. Grey was eventually charged in federal court with violating 18 U.S.C. § 875(c), which prohibits transmitting threatening communication “in interstate or foreign commerce.” 

In the proceedings that followed, Ms. Grey did not deny sending the messages containing threats but argued that the federal charges were improper because there was no proof that her messages traveled in interstate commerce. At trial, a government expert testified that iMessages are transmitted using the internet. The government did not offer any additional evidence that these specific messages had crossed state lines. Over Ms. Grey’s objection, the jury was instructed that “[u]se of the internet is adequate to demonstrate that the defendant transmitted the messages in interstate commerce.” The jury then convicted Ms. Grey. 

At Ms. Grey’s sentencing hearing, the court imposed a sentence of one year and one day of incarceration, followed by a three-year period of supervised release with various restrictions and conditions. One of these conditions prohibited Ms. Grey from using the internet “as a means of expressive communication,” particularly restricting her access to social media and other communicative channels online, with limited exemptions. Ms. Grey’s counsel objected to the condition of supervised release, arguing that it violated Ms. Grey’s fundamental rights to free speech and association under the U.S. Constitution and was substantively unreasonable. Ms. Grey argued that the condition was particularly burdensome because she has an adult son who lives in the Republic of the Philippines. Prior to her conviction, Ms. Grey and her son communicated primarily using the online messaging platform WhatsApp, which utilizes the internet. Ms. Grey argued that she and her son are very close and communicate via WhatsApp almost every day. 

Ms. Grey now appeals her conviction and sentence to the U.S. Court of Appeals for the 6th Circuit.

“The law itself is on trial in every case as well as the cause before it.”

1872

Cast in Stone

Born on a farm in Chesterfield, New Hampshire, on October 11, Stone grows up in Amherst, Massachusetts. (Stone’s family on his father’s side originally arrived from England to the Massachusetts Bay Colony in 1635.) 

1894

Stepping Stone

Graduates from Amherst College, where he plays on the football team and becomes acquainted with fellow student and future President Calvin Coolidge, who will later nominate Stone to the Supreme Court. His classmates predict Stone will “proceed to be the most famous man in [the class of] ’94.”

1898

A Stone’s Throw Away

Graduates from Columbia Law School, joins the New York City firm of Wilmer and Canfield (later Satterlee, Canfield, & Stone), and, in 1899, begins teaching at Columbia Law as a lecturer in law. In 1905, he resigns from the faculty to devote himself full-time to private practice.

1910

The New Stone Age

Returns to Columbia Law School as dean and resumes teaching. An inspiring educator who champions the increasingly popular “case” method, he teaches courses in trusts, contracts, mortgages, criminal law, and property. Students regard him as a friend and honor him by calling themselves “Stone-agers.” After repeatedly clashing with Columbia University President Nicholas Murray Butler, Stone resigns in 1923 and joins the Wall Street firm Sullivan & Cromwell.

1915

Stonewalling

Pushes back against Barnard College Dean Virginia Gildersleeve, who lobbies for women to be admitted to the Law School. In a letter to Gildersleeve, he tells her the faculty believes it is “inadvisable” for any law school to be coeducational. “What I would like to see is a serious undertaking to establish an independent school for women. This, I believe, is the proper solution of the problem,” he wrote her. (The Columbia Law faculty votes to admit women on the same terms as men in 1928.)

1924

Set in Stone

Appointed by President Calvin Coolidge as U.S. attorney general. His most enduring legacy as attorney general is selecting 29-year-old J. Edgar Hoover as acting director of the Justice Department’s Bureau of Investigation. Hoover, who becomes its director by the end of the year, leads the agency (renamed the Federal Bureau of Investigation in 1935) until his death in 1972.

1925

Rolling Stone

Nominated to the Supreme Court, where former President William Howard Taft is chief justice, Stone is the first nominee to have a confirmation hearing before the Senate Judiciary Committee. On the high court, he soon aligns himself with the titanic left-of-center justices Louis Brandeis and Oliver Wendell Holmes. 

1936

Killing Two Birds With One Stone

Delivers an eloquent and important dissent in United States v. Butler outlining two principles for declaring statutes unconstitutional.One is that courts are concerned only with the power to enact statutes, not their wisdom,” he writes. “The other is that while unconstitutional exercise of power by the executive and legislative branches of the government is subject to judicial restraint, the only check up our own exercise of power is our own sense of self-restraint.”

1938

Leaving No Stone Unturned

In Stone’s opinion in United States v. Carolene Products Co., his footnote No. 4 becomes what is universally recognized as “the most important footnote in constitutional law.” He writes that legislation should be “subjected to more exacting judicial scrutiny” when it is “directed at particular religious, or national, or racial minorities” who are victims of “prejudice,” which spawns the principle of judicial review known as strict scrutiny. 

1940

Hits a Stone Wall

Stone is the lone dissenter in Minersville School District v. Gobitis, maintaining that a group of Jehovah’s Witness children have the right to not salute the flag—in defiance of a Pennsylvania flag salute statute—because they believe the action to be against their religious beliefs. (They consider the flag a graven image.) Stone maintains that the Pennsylvania statute violates the students’ rights to freedom of speech and religion, and he reads his entire dissent from the bench.

1941

Etched in Stone

President Franklin Delano Roosevelt (who attended the Law School from 1905 to 1907) appoints Stone to succeed Chief Justice Charles Evans Hughes Sr. 1884. The poet Archibald MacLeish writes that Stone’s elevation, on July 3, to chief justice is “so clearly and certainly and surely right, it resounded in the world like the perfect word spoken at the perfect moment.” Prior to his appointment, Stone writes the majority opinion in United States v. Darby Lumber Co., holding the Fair Labor Standards Act of 1938 to be a valid exercise of federal power under the commerce clause. The Darby opinion made Stone “the intellectual leader of the Court’s center,” according to Stone biographer Alpheus T. Mason.

1943

Squeezing Blood From a Stone

The Supreme Court hears another flag salute case from the Jehovah’s Witnesses, West Virginia Board of Education v. Barnette. By a 6–3 vote, the justices side with Stone and overturn Gobitis. Justice Robert Jackson’s majority opinion echoes Stone’s lone dissent in Gobitis three years earlier.

1946

Engraved in Stone

Stone passes away on April 22 at 73, a few hours after having a cerebral hemorrhage while presiding over a session of the Supreme Court. Some 2,000 people attend his funeral at the Washington Cathedral, and he is buried at Rock Creek Cemetery. One of his eulogists is Alben Barkley, a senator from Kentucky and future vice president, who says, “No associate justice or chief justice . . . held a more abiding place in the affections of the American people and in the affections of all who knew him intimately and personally.” The Columbia Law Review memorializes him in September with the article “Harlan Fiske Stone: Teacher, Scholar and Dean.”
