1 The first division of interdicts is into orders of abstention, of restitution, and of production. The first are those by which the praetor forbids the doing of some act--for instance, the violent ejection of a bona fide possessor, forcible interference with the internment of a corpse in a place where that may lawfully be done, building upon sacred ground, or the doing of anything in a public river or on its banks which may impede its navigation. The second are those by which he orders restitution of property, as where he directs possession to be restored to a 'possessor of goods' of things belonging to an inheritance, and which have hitherto been in the possession of others under the title of heir, or without any title at all; or where he orders a person to be reinstated in possession of land from which he has been forcibly ousted. The third are those by which he orders the production of persons or property; for instance, the production of a person whose freedom is in question, of a freedman whose patron wishes to demand from him certain services, or of children on the application of the parent in whose power they are. Some think that the term interdict is properly applied only to orders of abstention, because it is derived from the verb 'interdicere,' meaning to denounce or forbid, and that orders of restitution or production are properly termed decrees; but in practice they are all called interdicts, because they are given 'inter duos,' between two parties. 2 The next division is into interdicts for obtaining possession, for retaining possession, and for recovering possession. 3 Interdicts for obtaining possession are exemplified by the one given to a 'possessor of goods,' which is called 'Quorum bonorum,' and which enjoins that whatever portion of the goods, whereof possession has been granted to the claimant, is in the hands of one who holds by the title of heir or as mere possessor only, shall be delivered up to the grantee of possession. A person is deemed to hold by the title of heir who thinks he is an heir; he is deemed to hold as mere possessor who relies on no title at all, but holds a portion of the whole of the inheritance, knowing that he is not entitled. It is called an interdict for obtaining possession, because it is available only for initiating possession; accordingly, it is not granted to a person who has already had and lost possession. Another interdict for obtaining possession is that named after Salvius, by which the landlord gets possession of the tenant's property which has been hypothecated as a security for rent.
