What is Relation?

Legal Definition
Civil law. The report which the judges made of the proceedings in certain suits to the prince were so called.

2. These relations took place when the judge had no law to direct him, or when the laws were susceptible of difficulties; it was then referred to the prince, who was the author of the law, to give the interpretation. Those reports were made in writing and contained the pleadings of the parties, and all the proceedings, together with the judge's opinion, and prayed the emperor to order what should be done. The ordinance of the prince thus required was called a rescript. (q. v.) the use of these relations was abolished by Justinian, Nov. 125.
