he admits that the summons was rightful.1 Nor [can he deny it] after resummons,  because if the summons was not lawful, the resummons and the day given by the  judge cannot be called unlawful. If the summons was not rightful but is not challenged  by the tenant when he appears, [the action] must proceed as though it were rightful.2  Even if the judge knows that it is unlawful he will be under no obligation on that  account to give the tenant an exception.] When both parties are present in court  and oyer of the writ is asked, if it has been lost by the negligence of the clerks or the  sheriff the assise will not remain because of that, provided it has once been read and  heard before the justices or in the county court, so that the jurors were chosen and a  view of the land made, if that is attested before the justices.3
What is to be done if the original writ has not been shown because it has been lost.
 If a justice has been specially assigned to take an assise and the original writ has  been lost, that will not be prejudicial if the justice shows his warrant, since the  original is contained in the warrant, but the converse is not true, that is, if the warrant  is lacking [but the writ is not] that the assise may proceed, unless [the judge] is, so to  speak, a major justice sent from the side of the lord king ad hoc.
If a tenant vouches a warrantor in an assise of mortdancestor; what the law is if the warrantor is within age.4
 When both the demandant and tenant are present in court [and] the tenant has a  warrantor and defender who is bound to defend him in his seisin against the demandant,  [let him be summoned] [When he vouches him to warranty we must  [first] see whether the warrantor is of full age or within age, for if within age the  tenant must show why he ought to warrant, charters or homage taken by his ancestor  or other matter, lest the voucher be frivolous or deceitful,5 which is also true in the  case of an adult, though he may be vouched to warranty without a charter.] by aid  of the court, if aid is sought; if it is not, let him who vouched cause him to appear.  Let the same be done with respect to a minor, once it is established that he ought  to warrant, though when he appears he is not bound to answer to his ancestor's  charters before his full age. 6The writ for summoning a warrantor resident outside the  county is this.7 If [he is resident] within it he may be summoned without writ. One  tenant may vouch several warrantors, who stand in the place of a single heir as a  single body,
