[PAULUS libro sexagensimo quinto ad edictum. ] §50.17.153.prFere quibuscumque modis obligamur, isdem in contrarium actis liberamur, cum quibus modis adquirimus, isdem in contrarium actis amittimus.
[PAULUS, in the sixty-fifth book on the edict.] Generally, by whatever modes we are bound, we are released by the same being executed in the opposite way, since by whatever modes we acquire, we lose by the same being executed in the opposite way.
ut igitur nulla possessio adquiri nisi animo et corpore potest, ita nulla amittitur, nisi in qua utrumque in contrarium actum est.
Therefore, just as no possession can be acquired except by intention and physical body, so none is lost, unless in regard to it both have been acted upon in the opposite way.
