the position of the possessor is the stronger.1 Let the chief lord then claim; the exception  will belong to him.
 Against whom does it lie? It is clear that it lies against any one, male or female, a  minor or one of full age, provided that if the minor against whom it is raised is the  tenant, the inquest as to bastardy may not proceed until he is of age, because before  his full age he is no more bound to answer an exception of bastardy than an assise,  since an exception of bastardy ends the matter both in possessory and proprietary  actions, as [in the roll] of the eyre of Martin of Pateshull in the county of Kent on the  feast of St. Michael in the eleventh and the beginning of the twelfth years of king  Henry, an assise of mortdancestor [beginning] if William of Herst,2 where the assise  was brought against a guardian who said that he held nothing except in the name of  wardship with one who was under age, who was then alleged to be a bastard. But if  it is put forward by one of full age against a minor-demandant the assise may proceed,  as in the same eyre, an assise of mortdancestor [beginning] if Henry Panfurere,3 [in  which] bastardy was objected against some of the demandants, as to whom the jurors  said that they were bastards because born before marriage, and the assise of mortdancestor  proceeded in the king's court.
Between what persons.
 The exception of bastardy does not lie in a possessory action, [in a plea of cosinage  no more than in an assise of mortdancestor, for ubi eadem ratio ibi idem jus,] between  kinsmen, only between strangers. Between such persons the question is one  of right and not possession, if it is an inheritance descending from a common  stock, [and] if this exception should be good between them the proprietas could be  determined in a possessory plea,4 though it could be objected that a bastard is a  stranger with respect to the true heir.5 Nevertheless that exception does not lie  between them, no more than does the assise, because it is not yet clear that he  against whom bastardy is objected may not prove himself legitimate.6
When it has been raised, with the reason, proof must follow.
 Though bastardy has been objected, with the reason specified, it is of no value unless  it is proved. 7When the tenant says that the demandant is a bastard and the demandant  replicates that he is legitimate, or conversely, we must see upon
