SAN FRANCISCO — After sweating through finals and before embarking on bar exam purgatory, law students have a moment of celebration ahead of them: graduation. This year, commencement speakers at some of California’s law schools include gay-marriage crusaders, a retired U.S. Supreme Court justice and a former government official who has stirred protest among Bay Area students.

David Boies and Ted Olson, the bipartisan legal team that overturned California’s ban on same-sex marriage, will speak at UC-Berkeley School of Law’s graduation May 10. Olson, a partner at Gibson, Dunn & Crutcher and a former U.S. solicitor general, is a 1965 graduate of Berkeley Law.
