[TRYPHONINUS libro nono disputationum. ] §19.2.8.prNos uideamus, ne non sexaginta praestanda nec quinquaginta sint, sed quanti interest perfrui conductione, tantundemque consequatur medius, quantum praestare debeat ei, qui a se conduxit, quoniam emolumentum conductionis ad comparationem uberioris mercedis computatum maiorem efficit condemnationem.
[TRYPHONINUS, Disputations, book nine] Let us consider whether the sum to be paid is not sixty, nor fifty, but rather the amount of his interest in enjoying the lease, and whether the intermediary should recover just so much as he is obliged to pay to the person who leased from him; since the advantage of the lease, calculated in comparison with the higher rent, produces a larger condemnation.
et tamen primus locator reputationem habebit quinquaginta, quae ab illo perciperet, si dominus insulae habitare nouissimum conductorem non uetuisset: quo iure utimur.
And yet, the first lessor will have a deduction of the fifty which he would have received from the former, if the owner of the apartment block had not forbidden the last tenant to live there: which is the rule of law we follow.
