Legum Doctor
（重定向自LL.D）
Legum Doctor (LL.D.; Doctor of Laws in English) is a doctorate-level academic degree in law, or an honorary doctorate, depending on the jurisdiction. The double L in the abbreviation refers to the early practice in the University of Cambridge to teach both Canon Law and Civil Law, the double L indicating the plural, Doctor of both laws. This contrasts with the practice of the University of Oxford where the degree that survived from the Middle Ages is the DCL or Doctor of Civil Law (only).
