[MARCELLUS libro quinto decimo digestorum. ] §40.5.9.prCum fidei heredis commisit, ne seruus alienam seruitutem patiatur experiri, potest confestim, ut fuerit alienatus, petere libertatem.
[MARCELLUS in the fifteenth book of the Digests.] When a testator has committed to the trust of the heir that a slave should not be permitted to experience the servitude of another, the slave can, as soon as he has been alienated, immediately petition for freedom.
sed ubi alienatio non est uoluntaria, sed necessitas alienandi ex causa testatoris pendeat, prope est, ut nondum debeat praestari fideicommissum, quod potest uideri defunctus nihil sensisse de huiusmodi casu alienationis.
But where the alienation is not voluntary, but the necessity of alienating depends on a cause originating from the testator, it is nearly the case that the trust-freedom should not yet be granted, because the deceased can be seen to have intended nothing regarding a case of alienation of this kind.
