Judicial activity encouraged the recording of royal legislation in writing which both looked to the past and attempted to set down law current in Henry's own day in the Leges Henrici Primi. This showed an awareness of the ideal of written law as a statement of judicial principles as well as of the practice of kingship. In this way, concepts of Roman law used by the Normans found their way into English law. The laws of Henry I in the Leges Henrici Primi have as subjects judicial procedure, proper judging, conduct of people involved in litigation, litigation procedure, required witnesses, evidence, credibility, quotes from legal references, oaths, perjury, geographical divisions of England, court sessions and attendance, order of court proceedings, adjournments, frankpledge, strangers, types of causes and their manner of hearing, royal jurisdiction, ecclesiastical pleas of the king, offenses, compensations, penalties, reliefs, the king's peace, forest pleas, exculpation, soke, jurisdiction of royal judges, the king's judges, summons, oathhelpers, transfer of cases, trials of pleas, unjust judgments, sureties, lords who sue, accusations, court procedure, pleadings, postponements, record of proceedings, failure to appear, counsel, summoning the hundred, summoning the county court, distraints, partners of common property, rights of jurisdiction of a lord over his man, holdings in farm, disputes between neighbors, trial by battle, slaves, pleas between a lord's reeve and those who are subject to him, suits by royal judges, wergelds, murdrum fine, letting go of a thief, slaying of or by a cleric, confessions, men of ill repute, ordeals, compensations, bondmen, intent, inheritance, dowries, homicide by magicians, definition of homicide, killing one's lord, foreigners, debtors, illegitimacy, foundlings, the king's peace, homicide in the king's court, royal highways, self-defense, drinking assemblies, mutual enemies, leading into wrong-doing, lent arms, marauders, weapons, killing a relative, pledge, negligence, and wounds to body parts.
