[IDEM libro trigensimo nono ad edictum. ] §5.1.62.prInter litigantes non aliter lis expediri potest, quam si alter petitor, alter possessor sit: esse enim debet qui onera petitoris sustineat et qui commodo possessoris fungatur.
[THE SAME, on the Edict, Book XXXIX.] Between litigants, a lawsuit cannot otherwise be resolved than if one is the petitioner and the other is the possessor; for there must be someone to bear the burdens of a petitioner and someone to enjoy the advantage of a possessor.
