William Joseph Kayatta Jr.

William Joseph Kayatta Jr. (born 1953) is a senior United States circuit judge on the Court of Appeals for the First Circuit. Appointed by President Barack Obama and confirmed in early 2013, he has served on the appellate bench for more than a decade before assuming senior status in late 2024 while continuing to hear cases. Prior to his judicial career, Kayatta practiced law in Maine, engaged extensively in pro bono service, and contributed to national legal processes such as Supreme Court nominations and interstate water‑rights disputes.

Early life and legal career

Kayatta was born in Pawtucket, Rhode Island, in 1953. He pursued undergraduate studies at Amherst College, receiving a Bachelor of Arts degree in 1976. Continuing his education in law, he attended Harvard Law School, where he earned a Juris Doctor magna cum laude in 1979. Following graduation, Kayatta clerked for Chief Judge Frank M. Coffin of the First Circuit from 1979 to 1980, gaining early exposure to federal appellate practice.

In 1980, Kayatta joined the Portland, Maine firm Pierce Atwood LLP as an associate. His work at the firm concentrated on complex trial and appellate litigation, leading to his promotion to partnership in 1986. Over the course of his private‑practice career, he argued two cases before the United States Supreme Court, reflecting a breadth of experience in high‑level advocacy.

Kayatta’s involvement extended beyond courtroom representation. In 2010, he served as lead investigator for an American Bar Association committee that evaluated the qualifications of then‑Supreme Court nominee Elena Kagan. That same year, his contributions to pro bono service were recognized by the Maine Bar Foundation with the Howard H. Dana Award, honoring a career-long commitment to assisting low‑income residents of Maine. Additional commendations came from the Disability Rights Center of Maine, Maine Equal Justice Partners, and the Maine Children’s Alliance for his representation of disabled children.

His leadership roles within the legal community included presidency of the Maine Bar Foundation and chairmanship of the Professional Ethics Commission for Maine lawyers. In April 2011, the United States Supreme Court appointed Kayatta as special master in an interstate water‑rights dispute known as Kansas v. Nebraska and Colorado. The Special Master’s Report he prepared was later adopted in full by the Supreme Court, underscoring his analytical contributions to a complex federal issue.

Federal appellate service

President Barack Obama nominated Kayatta on January 23 2012 to fill a vacancy on the First Circuit created when Judge Kermit Lipez assumed senior status at the end of 2011. The Senate Judiciary Committee held a hearing on March 14 2012 and reported his nomination to the full Senate by voice vote on April 19 2012, with Senators Jeff Sessions and Mike Lee recorded as voting against the report.

Although the nomination proceeded without substantive controversy, it encountered procedural delays due to broader Senate tactics that stalled several of President Obama’s judicial appointments. The original nomination expired at the close of the 112th Congress on January 2 2013. Kayatta was renominated the following day, and the Judiciary Committee again reported his candidacy by voice vote on February 7 2013, this time noting a single dissenting vote from Senator Sessions.

The full Senate confirmed Kayatta on February 13 2013 by an 88–12 vote, and he received his commission the next day. He occupied the seat designated as CA10311 and served as an active circuit judge until October 31 2024, when he elected to take senior status. In senior status, Judge Kayatta continues to participate in the court’s workload, contributing his experience to panels hearing appeals from district courts within the First Circuit’s jurisdiction.

Jurisprudence and legacy

During his tenure on the First Circuit, Judge Kayatta authored opinions that addressed a range of legal issues, reflecting both the circuit’s regional concerns and matters of national significance. In August 2017, he wrote for an en banc panel that rejected a lawsuit seeking to extend voting rights to residents of Puerto Rico, a decision rendered amid dissenting views from several colleagues.

In April 2020, Kayatta authored a unanimous opinion holding that the Board of Immigration Appeals had erred in denying asylum to a survivor of domestic violence without adequately considering the specific allegations presented. The ruling emphasized procedural fairness in immigration adjudication and underscored the court’s role in reviewing agency determinations for legal error.

One of the most widely reported decisions involving Judge Kayatta occurred in July 2020, when he wrote for a 2–1 majority that vacated the death sentence imposed on Dzhokhar Tsarnaev, the perpetrator of the Boston Marathon bombing, and overturned three related firearm convictions. The panel identified procedural deficiencies in the sentencing phase that warranted relief. Although the United States Supreme Court later reversed this decision in March 2022, reinstating the death penalty, the First Circuit’s opinion remains a notable example of appellate scrutiny over capital sentencing procedures.

In January 2024, Kayatta authored a unanimous opinion that revived a lawsuit filed by Mexico against several U.S. gun manufacturers and a distributor. The case centered on allegations that the defendants’ practices contributed to a flow of firearms into Mexico, facilitating violent crime. Although the district court had dismissed the suit under the Protection of Lawful Commerce in Arms Act (PLCAA), Kayatta concluded that exceptions within the PLCAA—specifically those concerning aiding and abetting firearms trafficking—allowed the claims to proceed. The Supreme Court granted certiorari in October 2024 to review this determination, indicating the ongoing relevance of his analysis to national debates over gun regulation.

Beyond specific rulings, Judge Kayatta’s legacy includes his sustained engagement with professional ethics, access to justice, and public service. His early work as a special master on an interstate water dispute contributed to the Supreme Court’s understanding of complex environmental litigation. His leadership in Maine’s bar organizations and recognition for pro bono advocacy reflect a career-long commitment to serving underrepresented populations. As a senior judge, he continues to shape First Circuit jurisprudence while mentoring newer members of the federal judiciary.

Collectively, William J. Kayatta Jr.’s educational background, private‑practice experience, extensive public‑service contributions, and appellate opinions illustrate a multifaceted legal career that bridges regional practice and national judicial responsibilities. His service on the United States Court of Appeals for the First Circuit underscores the role of appointed judges in interpreting federal law, safeguarding procedural rights, and addressing evolving societal challenges within the framework of the Constitution and statutory authority.
