May it please you of your gracious lordship to cause the full record to be brought before you, with all attachments to the same concerning the said writ of scire facias, in the present parliament, that they may be inspected and examined for error, and to forewarn Roger Mortimer, Earl of March, cousin and heir of the aforesaid Roger son of Edmund, and others who are to be forewarned in the matter, to be before you at the next parliament to hear the said errors; and if they know of anything to say wherefor the aforesaid judgment on the said writ of scire facias should not be reversed, and the aforesaid supplicant restored to his said possession with the issues and profits in the meantime since the said loss, and also to do right and justice to the parties in the aforesaid manner.
