Judge dismisses Sam Altman’s sister’s sexual abuse lawsuit

3 sources →

A US district judge has dismissed a lawsuit filed by Ann Altman against her brother, OpenAI CEO Sam Altman, which alleged sexual abuse occurred during their childhood. Judge Zachary Bluestone dismissed the case not on the merits of the allegations, but because Ann Altman refused to attend a court-ordered independent medical examination. The dismissal was made with prejudice, preventing the case from being refiled.
