[POMPONIUS libro uicesimo septimo ad Sabinum. ] §21.2.34.prSi mancipium ita emeris, ne prostituatur et, cum prostitutum fuisset, ut liberum esset: si contra legem uenditionis faciente te ad libertatem peruenerit, tu uideris quasi manumississe et ideo nullum aduersus uenditorem habebis regressum.
[POMPONIUS, On Sabinus, Book Twenty-Seven] If you have bought a slave on the condition that he should not be prostituted, and that if he should be prostituted, he should be free; if through your acting contrary to the terms of the sale he attains freedom, you are deemed, as it were, to have manumitted him, and therefore you will have no recourse against the seller.
§21.2.34.1Si communi diuidundo mecum actum esset et aduersario seruus adiudicatus sit, quia probauit eum communem esse, habebo ex duplae stipulatione actionem, quia non interest, quo genere iudicii euincatur, ut mihi habere non liceat.
If an action for the division of common property has been brought against me, and the slave has been adjudicated to my opponent because he proved that the slave was held in common, I will have an action on the stipulation for double value, because it makes no difference by what kind of trial eviction occurs so that I am not permitted to hold the property.
§21.2.34.2Duplae stipulatio euictionem non unam continet, si quis dominium rei petierit et euicerit, sed et si Seruiana actione experiatur.
The stipulation for double value covers not just one type of eviction, where someone claims ownership of the property and evicts, but also where action is taken by the Servian action.
