If there are several demandants, whether there is one tenant or several, the same  procedure must be observed in essoins as in the case of several tenants, that is, let  all have a single essoin, together and on one day or separately and successively,  [because in this matter nothing will be permitted the reus which is not permitted  the actor,]1 which does not occur except for some important reason, since a demandant  ought to desire advancement of the suit rather than its delay, and if one  of the several demandants essoins himself, all the others are subject to postponement  and delay. If one of the several defaults, after awaiting the fourth day the  tenant will withdraw quit of the writ, as though all had defaulted. Thus the negligence  of one will be prejudicial to all the others, for either all sue or none.2 The same  must be said of a husband and wife who are demandants, that the absence of the  husband will be prejudicial to the wife and conversely. If some of the several,  whether they are demandants or tenants, are present and some essoin themselves  and have a day, those who were present will always have the same day lest the  unitary nature of the plea be divided.3 And let there always be added in the essoin,  as a precaution, who has essoined himself to one day or another, so that at the end  it may be known4 whether they have had all their essoins or not.
If a tenant has appointed an attorney.
 Suppose that a tenant cannot sue in his own person, or though he can, on the chance  that he may not, appoints an attorney as a precaution. The essoin then lies in the  person of the attorney, not in the person of the lord, whether it is the demandant  who has appointed the attorney or the tenant,5 because the attorney represents the  person of his lord in [almost] all matters. [I say almost because of the essoin of  bed-sickness as will be explained below.]6 And though [when] one has appointed an  attorney he may sue in his own person whenever he wishes,7 and may [remove him],  because this is a matter of will, the appointment as attorney always continues until  the lord removes him, and as long as it continues an essoin will never lie in the  person of the lord, except when both essoin themselves8 as in the case of two  attorneys or several, because if the lord cannot come in person he may come by  attorney, but not conversely, which is not true in the case of the two attorneys. But  what if the lord, when he has appointed an attorney and has not
