The Professorship in Jurisprudence, at University College, is the one previously held by H.L.A. Hart; to take up the Senior Research Fellowship at All Souls, Professor Gardner–perhaps best-known for his work in philosophy of criminal law, though he has written widely in legal and moral philosophy–will have to resign that post.   There is one other statutory Chair in jurisprudence at Oxford–the Professorship in the Philosophy of Law at Balliol held by Leslie Green–and Timothy Endicott, also at Balliol, holds a Personal Chair as well.  So this will present an opportunity for Oxford to make another senior appointment in the field.
