“The economic and social life of Sumer was characterized by the all-pervading concepts of law and justice. Significant economic and legal reforms were introduced as early as the twenty-fourth century B.C. by the Lagash ruler Urukagina. Law codes were promulgated as early as the twenty-first century, and one of these, the Ur-Nammu law code, has been recovered in part. Sumerian legal documents have been excavated in large numbers: contracts, deeds, wills, promissory notes, receipts, and actual court decisions that became legal precedents. In theory, it was the king who was responsible for the administration of law and justice; in practice, the city governor or his representative, the mashkim, attended to the administrative and legal details. Court cases were usually heard by tribunals of three or four judges. Suits could be brought either by private parties or by the government. Evidence was taken in the form of statements from witnesses and experts, or was obtained from written documents. Oath-taking played a considerable role in court procedure.” – Samuel Noah Kramer, “Sumerian History, Culture, and Literature”
