have restored the inheritance to him and others have refused to do so, excepting  bastardy against him, the refusal is of no avail, nor is an enquiry to be ordered or  sent to court christian, as [in the roll] of the eyre of Robert of Lexinton, [the case] of  a certain Adam of Aston,1 [where he] wished to send the plea to court christian, a  ruling which was revoked and corrected by Martin of Pateshull.
Who may allege bastardy.
 We must see who may allege bastardy. It may be done by him who has the right to  do so, as by the true heir against him who claims to be the heir when he is not, whether  he who alleges it is the demandant or the tenant. Also one who stands in the place of  the heir may raise it, as the chief lord when he is in seisin of the inheritance as of his  escheat for failure of his tenant's heirs,2 when there is no heir other than him who  claims, who is a bastard. If there are several who claim to be heirs, it will not then be  proper for the chief lord to object bastardy, for though it lies against the heir, it is  not for him, to raise it, 3<And that it is not for the chief lord to raise it may be proved  [in the roll] of Easter term in the twelfth year of king Henry in the county of Berkshire,  [the case] of Robert Achard,4 unless the land ought to be his escheat, as in [the  roll] of the eyre of Martin of Pateshull in the county of York in the tenth year of  king Henry, an assise of mortdancestor [beginning] if Ralph de Bulli.5 But when  the chief lord has once acknowledged the bastard as heir, or has returned part of  the inheritance to him as one who is legitimate, if he later wishes to object bastardy  against him he will not be heard, as [in the roll] of Hilary term in the fourteenth year  of king Henry in the county of Middlesex, [the case] of the abbot of St. Albans and  William son of Ralph.>6 because it lies for the true heir, against his brother or7 any  other who claims to be heir though a bastard, whether there is a single heir or several  legitimate heirs, or a single bastard or several such who claim to be heirs, whether  they are tenants or demandants.8 If both are bastards, the demandant and tenant,  and the demandant raises the objection of bastardy against the tenant and the tenant  in his replication says the demandant is a bastard, the demandant must show that  he is legitimate, otherwise he will take nothing, since here
