For Neal Katyal, former acting solicitor general of the United States, speaking in the nation's "marble palace," the U.S. Supreme Court, is a familiar experience. However, the Hogan Lovells partner took to a very different stage and audience on September 9 as part of the centennial anniversary of the Peace Palace, home of the International Court of Justice in the Hague.

Katyal was invited to the palace with eight others by TEDxHagueAcademy, part of TED, a nonprofit organization that annually invites the world's leading thinkers and doers to share "world-changing ideas." Each speaker has 18 minutes to explain his or her ideas. The speeches are videotaped and then made available for free to the world.
