He who hath an especial charge, by virtue of his office, to see that the king's peace be kept. Before the reign of Edward III., who created Justices of the peace, there were sundry persons Interested to keep the peace, of whom there were two classes: one of which had the power annexed to the office which they hold; the other had it merely by itself, and were hence called wardens or conser. vators of the peace. Lambard, Eirenarchia, 1. 1, c. 3 This latter sort are superseded by the modern justices of the peace; 1 Bla. Com. 349. The king's majesty was the principal conservator of the peace within all his dominions. The lord chancellor or keeper, the lord treasurer, the lord high steward of England, and the lord mareschal and lord high constable of England, all the justices of the court of king's bench (by virtue of their offices), and the master of the rolls (by prescription) were general conservators of the peace throughout the whole kingdom, and might commit all breakers of it, or bind them in recognizances to keep it: the other judges were only so in their own courts. The coroner was also a conservator of the peace within his own county, as also the sheriff, and both of them might take recognizances or security for the peace. Constables, tythingmen, and the like were also conservators of the peace within their own jur- isdiction; and might apprehend all breakers of the peace, and commit them until they found sureties for their keeping it. The judges and other similar officers of the various states, and also of the United States, are conservators of the public peace, being entitled "to hold to the security of the peace and during good be- havior." The Constitution of Delaware (1831) pro- vides that:- "The members of the senate and house of representatives, the chancellor, the judges, and the attorney-general shall, by virtue of their offices, be conservators of the peace throughout the state; and the treasurer, secretary, and prothonotaries, registers, recorders, sheriffs, and coroners, shall, by virtue of their offices, be conser- vators thereof within the counties respec tively in which they reside." CONSERVATOR TRUCIS (Lat.). An officer whose duty it was to inquire into all offences against the king's truces and safe conducts upon the main seas out of the liberties of the Cinque Ports. Under stat. 2 Hen. V. stat. 1, c. 6, such offences are declared to be treason, and such officers are appointed in every port, to hear and determine such cases, "according to the ancient maritime law then practised in the admiral's court as may arise upon the high seas, and with two associates to determine those arising upon land." 4 Bla.
