A US district judge dismissed a lawsuit filed by Ann Altman against her brother, OpenAI CEO Sam Altman, on Tuesday. Ann Altman had accused Altman of repeatedly sexually abusing her more than two decades ago. Altman has denied the allegations.

US District Judge Zachary Bluestone ruled in the dismissal that Ann Altman had refused to appear for an independent medical examination despite warnings that her failure to do so would result in case dismissal.

The lawsuit originated from allegations of abuse spanning multiple decades. The specific circumstances that prompted the legal action and the timing of the filing are not detailed in the available information. No statement from either party is provided.
