As previous posts have noted, all of the current Supreme Court justices have Ivy League law degrees. The New York Times reports on Governor Jerry Brown's appointments in California:
Of the three people Mr. Brown has nominated to the seven-member Supreme Court — the latest confirmed on Monday — not one had a day of judicial experience: Two are law professors and the third is an associate attorney general in the Justice Department.
They are all graduates of the same law school — Yale — which also counts among its alumni a California lawyer who made a career in politics, Mr. Brown.
As for the Yale connection, the governor said that he would certainly consider graduates of other law schools for future nominations. But he added, “Yale is pretty good — it’s a small school, so it’s very selective.”
