Teacher: Now, understand the problem? Solve this instance: Passage: The administration of justice was of particular importance to John. Several new processes had been introduced to English law under Henry II, including novel disseisin and mort d'ancestor. These processes meant the royal courts had a more significant role in local law cases, which had previously been dealt with only by regional or local lords. John increased the professionalism of local sergeants and bailiffs, and extended the system of coroners first introduced by Hubert Walter in 1194, creating a new class of borough coroners. John worked extremely hard to ensure that this system operated well, through judges he had appointed, by fostering legal specialists and expertise, and by intervening in cases himself. John continued to try relatively minor cases, even during military crises. Viewed positively, Lewis Warren considers that John discharged "his royal duty of providing justice ... with a zeal and a tirelessness to which the English common law is greatly endebted". Seen more critically, John may have been motivated by the potential of the royal legal process to raise fees, rather than a desire to deliver simple justice; John's legal system also only applied to free men, rather than to all of the population. Nonetheless, these changes were popular with many free tenants, who acquired a more reliable legal system that could bypass the barons, against whom such cases were often brought. John's reforms were less popular with the barons themselves, especially as they remained subject to arbitrary and frequently vindictive royal justice. Question: When was the system of coroners first introduced?
