the church of N., the advowson of which church A. recently recovered in our court  before us (or before our justices at Westminster, or before our justices appointed  for this purpose) against the same B. (or against another, such a one) by an assise  of darrein presentment there taken between them (or by the judgment of our  court, or in some other way) as to which the same A. complains that the aforesaid B.  wrongfully and against our crown (or in contempt of our court) impedes him. And  have etc. Hence we must see what is meant by to impede, that the difference between  a writ of quare impedit and of quare non permittit may be understood. To  impede is to place one's foot in the right of another, which the other has in the right  to present, with quasi-seisin and right of some kind and to some degree, because he  who impedes so that one may not use his seisin or quasi-seisin imposes his foot upon  another's right etc. Thus the writ of quare impedit lies. But if he, the presentor, has  no seisin at all, or quasi-seisin through the causa of gift,1 though from another source  the right to present belongs to him,2 [as] by reason of a tenement he holds for life  through some fortuitous event, by reason of dower [or] by the law of England, or to a  farmer by reason of a lease or a creditor by reason of a pledge, since no seisin or quasi-seisin  has come to him, one could not put his foot in the right and3quasi-seisin he  did not have. Therefore the writ of quare impedit does not lie but the writ of quare non  permittit.4 This is the difference between quare impedit and quare non permittit.  The word impedit is compounded of in and pes, pedis, and hence he impedes  who strives to place his foot in another's right, where no right belongs to him, neither  of property nor of possession, [as where], when he once had [both] he transferred them  to another by a causa of some kind or by judgment, but5 [if] when he once had both,  he transferred the right of possession to another by some causa, who has not yet used  and whom he does not permit to use, the writ of quare non permittit lies for him against  the owner, that is, why the owner does not permit the possessor to use his right of  possession.6
The writ of Quare non permittit.
 The king to the sheriff, greeting. Order such a one that rightfully and without delay  he permit such a one to present a suitable parson to such church, which is vacant and  in his gift, as he says, as to which he complains that the aforesaid wrongfully impedes  him. And unless he does so, and if the same [plaintiff] has made you secure etc., then  summon him by good summoners
