So why isn’t Stanford on that list? It has two Justices – Chief Justice William Rehnquist and Justice Sandra Day O’Connor. They both graduated, too; no “one-year program” or “part-time” studies.
Justice Ginsburg is on the list twice. She spent two years at Harvard, but moved to Columbia for her third year because her husband Marty, who was a year ahead of her, had taken a job in New York. Under modern practices, she would have graduated from Harvard anyway, but back then she formally transferred and got a Columbia degree. She’s still the only person anyone knows about to have a position on two major law reviews.
Anyway, it would be more relevant to this thread – “Stanford Pre-Law” – to look at the undergraduate institutions of Supreme Court Justices, not their law schools.
