Lawsuit Dismissed Over Refused Medical Examination

A federal court has officially dismissed the legal action brought against OpenAI chief executive Sam Altman by his sister. As detailed by The Verge, US District Judge Zachary Bluestone dismissed the lawsuit filed last year alleging that her brother, OpenAI CEO Sam Altman, had sexually abused her throughout her childhood on Tuesday. The case was ultimately dismissed not on the merits of the allegations, but because Ann Altman failed to appear for an independent medical examination and missed other required deadlines despite explicit warnings from the court.

Additional reporting from Engadget noted that the judge wrote that Ann refused to comply with the medical examination order. Because the case was dismissed with prejudice, the current legal action cannot be refiled in that court. However, Judge Bluestone chose to deny Sam Altman's request to recover attorney fees and costs associated with defending against the litigation.

Background of the Legal Claims and Revisions

The legal dispute first began when Ann Altman filed her complaint in January 2025. In her filings, she accused Sam of sexually abusing her when she was a child, claiming the incidents took place at the family home in Missouri between 1997 and 2006. The initial allegations asserted that the behavior started when she was three years old and he was 12, with a final instance allegedly occurring after her brother had reached adulthood.

The case underwent procedural changes earlier in the year. In March, Judge Bluestone ruled that the original sexual assault and battery claims had expired due to the statute of limitations. Nevertheless, the court permitted Ann to refile her complaint under a specific Missouri childhood sexual abuse law, leading to the amended suit that faced final dismissal this week.

Family Response and Counterclaims

From the outset of the litigation, the Altman family strongly denied the accusations. When the lawsuit was initially filed, a joint statement shared by Sam Altman, his mother, and his brothers addressed the public controversy directly. The family asserted that Annie had made deeply hurtful and entirely untrue claims about the family, specifically targeting Sam, and emphasized that the situation caused immense pain to everyone involved.

Further public statements from the family elaborated on these assertions, claiming that Ann faced ongoing mental health challenges and refused conventional medical treatment while lashing out at relatives attempting to offer support. Alongside the dismissal of the primary complaint on Tuesday, Judge Bluestone also approved a request from the OpenAI CEO to withdraw a defamation counterclaim that he had previously filed against his sister.

Legal Representation and Final Proceedings

Throughout the course of the lengthy litigation, Ann Altman's legal representation experienced changes. Santos Perez, the attorney who had previously represented her in the matter, officially withdrew from the case. Following the dismissal announcement, Perez provided a statement indicating that he was no longer authorized to comment on the proceedings but maintained his personal belief in his former client.

As covered extensively across multiple outlets, including initial coverage by The Guardian regarding the court warnings, the failure to meet mandatory discovery obligations and medical evaluation requirements sealed the outcome of the case. With the dismissal with prejudice now finalized by the federal court, the prolonged legal battle initiated by the OpenAI executive's sister has officially come to a close.
