Madox, Baronia Anglica, p. 42 and 58; West's Inquiry, p. 28, 33. That a baron could only be tried by his fellow barons was probably a rule as old as the trial per pais of a commoner. In 4 E. III. Sir Simon Bereford having been accused before the lords in parliament of aiding and advising Mortimer in his treasons, they declared with one voice that he was not their peer; wherefore they were not bound to judge him as a peer of the land; but inasmuch as it was notorious that he had been concerned in usurpation of royal powers and murder of the liege lord (as they styled Edward II.), the lords, as judges of parliament, by assent of the king in parliament, awarded and adjudged him to be hanged. A like sentence with a like protestation was passed on Mautravers and Gournay. There is a very remarkable anomaly in the case of Lord Berkley, who, though undoubtedly a baron, his ancestors having been summoned from the earliest date of writs, put himself on his trial in parliament, by twelve knights of the county of Gloucester.
