The earliest mention of Roman Law in the Common Law of England is found in 1237–1238, in which a question of whether a palatinate can be partitioned among co-heirs. The justices could find no precedent for such a thing in English law, nor in the Magna Carta, nor in Roman Law (in iure scripto), therefore, they adjoined (delayed) their decision. In Bracton's time, it had been determined that the Emperor of the Holy Roman Empire was deemed to be a subject of the King of England while in England: Ricardus Rex Alemanniae (Rex Romanorum semper augustus) was impleaded for novel disseisin.
