Mariah Carey Wins Legal Victory as Judge Dismisses Brother Morgan’s Defamation Lawsuit Over Her 2020 Memoir

Mariah Carey has scored a decisive legal victory in her long-running dispute with her older brother, Morgan Carey, after a judge formally dismissed his defamation lawsuit over her 2020 memoir, The Meaning of Mariah Carey. The ruling, handed down on Monday, October 19, brings a significant chapter in the family feud to a close — at least for now — after Morgan indicated that he intends to appeal.

Morgan Carey, 66, first filed suit against his superstar sister in 2021, accusing her of defaming him in the highly personal memoir. At the center of the legal battle were claims that Mariah, 57, wrote about Morgan allegedly trafficking “powdered party favors” — a phrase widely understood as a reference to cocaine — and further alleged that he had spent time in prison. Those passages, Morgan argued, cast him in a false and damaging light and caused him substantial harm.

According to legal filings and reports from Rolling Stone and Billboard, Morgan’s lawsuit alleged that Mariah recklessly published damaging statements about him without properly verifying their accuracy. He contended that the memoir, despite being marketed as a candid and emotional life story, contained assertions about him that were defamatory and untrue. The case quickly became one of the more closely watched celebrity family legal disputes, in part because of the deep personal history between the siblings and in part because of the legal principles at stake regarding memoir writing and public figures.

However, in her ruling, Judge Leslie A. Stroth found that Morgan had failed to clear the high legal bar required for defamation claims brought against public figures. Under New York law, a public figure who brings a defamation lawsuit must demonstrate not only that a statement was false and damaging, but also that the defendant acted with “actual malice.” That standard, rooted in decades of First Amendment jurisprudence, requires proof that the person making the statement either knew it was false at the time or acted with reckless disregard for whether it was true or false. It is widely regarded as one of the most difficult standards for plaintiffs to meet in defamation litigation.

In her decision, Judge Stroth made clear that Morgan’s arguments did not meet that burden. “The Court finds that Plaintiff has not sufficiently pleaded actual malice on the part of Defendant,” the judge wrote. She went on to explain that Morgan had alleged Mariah was more concerned with the “commercial viability” of her memoir than with verifying the truth of her statements, and that her sources for the contested statements were anonymous or unverifiable. But those allegations, the judge said, were not enough. “Notably, Plaintiff fails to provide any proof that Defendant made such statements with knowledge of their falsity or with reckless disregard for the truth,” the ruling continued.

The decision is a significant legal win for Mariah Carey, who has spent much of her career in the public eye and has endured intense scrutiny of both her professional and personal life. Her attorney, John Rosenberg, responded to the ruling by praising the court’s decision and emphasizing its broader implications for authors and public discourse.

“Ms. Carey is gratified that the Court recognized that her memoir addresses significant issues of public interest and dismissed her brother’s defamation claims in their entirety,” Rosenberg told Billboard on Monday.

He also stressed that the ruling carried importance beyond Mariah herself. “Ms. Carey believes the importance of the Court’s decision goes well beyond her own interests in this particular litigation as it confirms that authors must be afforded broad protection when they speak out on matters of public concern,” Rosenberg added.

Morgan Carey’s legal team, however, was quick to signal that the fight is not necessarily over. Richard Altman, Morgan’s attorney, told Rolling Stone that he disagreed with the judge’s ruling and planned to pursue an appeal. “We respectfully disagree with today’s decision as being completely inconsistent with prior rulings in the case,” Altman said on Monday. “We intend to appeal it very soon.”

The appeal means that the legal dispute could continue for months or even years, but Monday’s ruling nevertheless represents a substantial setback for Morgan’s case. Legal observers noted that appellate courts generally review trial court dismissals with a great deal of deference, especially in cases involving the actual malice standard. To succeed on appeal, Morgan will need to convince a higher court that the judge erred in her application of the law or that the facts of the case warranted allowing the lawsuit to proceed. Given the strict requirements of New York defamation law, that will likely be an uphill battle.

The lawsuit was only one part of a deeply complicated family history that Mariah Carey has addressed publicly at various points throughout her career. Mariah is the youngest of three children born to Alfred and Patricia Carey, both of whom have since died. Alfred Carey passed away in 2022, and Patricia Carey died in 2024. Mariah’s older sister, Alison Carey, also passed away in 2024, in a tragic and widely reported sequence of events.

In August 2024, Mariah confirmed the devastating news that she had lost both her mother and her sister around the same time. The singer, known for hits like “We Belong Together” and “Hero,” released a heartfelt statement expressing her grief. “My heart is broken that I’ve lost my mother this past weekend,” she said at the time. “Sadly, in a tragic turn of events, my sister lost her life on the same day.” She added, “I feel blessed that I was able to spend the last week with my mom before she passed. I appreciate everyone’s love and support and respect for my privacy during this impossible time.”

The deaths came after years of estrangement and public tension between Mariah and her siblings. Her memoir, The Meaning of Mariah Carey, was released in 2020 and became a bestseller, offering readers an unusually intimate look at her childhood, her rise to fame, her marriages, and her complicated family relationships. The book was widely praised for its candor, but it also reignited old wounds within the Carey family. Both Morgan and Alison publicly pushed back against aspects of the book, and Morgan’s defamation lawsuit was just one manifestation of a family conflict that played out in public view.

Throughout the litigation, Mariah’s legal team consistently maintained that the memoir was a protected expression of her own life story and that she had every right to write about her experiences, including her relationships with family members. They argued that the statements in question were either true, based on reliable sources, or constituted opinion and rhetorical hyperbole rather than actionable defamation. In dismissing the case, Judge Stroth effectively endorsed the position that allowing public figures to speak candidly about matters of public concern requires broad legal protection, even when the subject matter involves personal family history.

The ruling also underscores an important point about memoirs and the law: writing about one’s own life often involves recounting events from memory, and memories can be imperfect. Courts have long recognized that public figures should not be held liable for defamation based merely on disputed recollections, especially when the plaintiff cannot prove deliberate falsehood or reckless disregard for the truth. In this case, Judge Stroth found that Morgan had not presented any direct evidence that Mariah knowingly lied about him or that she ignored obvious red flags about the accuracy of the statements.

For Mariah Carey, the legal victory is likely a welcome relief after a difficult few years marked by personal losses and ongoing family strife. While she has continued to perform and release music, the shadow of the lawsuit has lingered over her public appearances. Now, with the case dismissed at the trial level, she can focus on her career and her family without the immediate threat of another round of legal proceedings — although Morgan’s promised appeal means the matter may not be entirely closed.

Still, Monday’s ruling sends a clear message about the limits of defamation law when it comes to memoirs and other works of nonfiction that touch on matters of public interest. Authors are not immune from liability, but they are entitled to significant latitude when recounting their own experiences, particularly when those experiences involve newsworthy subjects. As Mariah’s attorney noted, the decision could have broader implications for writers and publishers across the country.

For now, Mariah Carey can add this legal victory to her long list of accomplishments. But the underlying family trauma and fractured relationships that gave rise to the lawsuit are unlikely to be resolved by a court ruling. The memoir, the lawsuit, and the deaths of her mother and sister have all become part of the complicated legacy of one of pop music’s most enduring and beloved icons. While the legal system has now weighed in on the defamation claims, the personal story behind them remains far more tangled.

As the possibility of an appeal looms, fans and legal observers will be watching to see whether Morgan Carey follows through on his stated intention to fight the ruling. If he does, the case will move to an appellate court, where judges will review the lower court’s decision and determine whether any errors were made. But based on the standards applied by Judge Stroth, Morgan will face an extremely difficult burden in trying to revive his claims. For now, Mariah Carey has emerged victorious — legally, at least — in the latest chapter of a family saga that has played out in the headlines for years.
