[001] may bring different assises for the same thing on the deaths of two ancestors at one [002] and the same time, in which case the last seisin must be adjudicated [first]. But an [003] assise is not to be taken on an assise on the seisin of two ancestors between the same [004] persons with respect to the same thing, as where land is given to A. and B. his wife; [005] if A. dies first, seised, an assise on the death of A. does not lie for the heir during the [006] life of B., nor conversely. But when both die, an assise of mortdancestor lies for the [007] heir on the seisin of him who last died seised, but if the assise finds against the heir, [008] because of a gift made by him who last died seised, no recourse can be had to another [009] assise on the death of him who died first.1 If land is given to one thus, in maritagium [010] with his wife; no assise of mortdancestor lies except at the death of the mother, and [011] hence if he takes nothing by the assise on the death of the mother, he cannot have [012] recourse to the seisin of the father by the assise. The assise is not to be taken on an [013] assise in an assise of darrein presentment if the exception that it was taken at another [014] time is raised. If it is taken in error, when no mention was made of the first, a conviction [015] will lie, for the second, not the first, though faith is to be placed in neither [016] of them de jure. In assises to recognize utrum, an assise will never be taken on an [017] assise, though sometimes a conviction lies, because it determines the right and possession [018] and immediately passes over into the authority of res judicata, which provides [019] an exception.
That a conviction is not to be taken on a conviction.
[021] A conviction must not be taken on a conviction, any more than an assise on an assise. [022] Hence we must see, if a conviction follows a conviction, whether it is the same assise [023] as to which a conviction was formerly taken, the same thing or a different one, and [024] whether between the same persons or different ones.2 If it is one and the same person, [025] the same thing and the same assise, a conviction will never be taken on a conviction, [026] though emendation follows in another way, in the form of certification by examination, [027] as was seen in [the portion] on the taking of assises.3 If the persons are different, [028] the things and the assises different, as may often be seen by the records, a conviction [029] may well follow a conviction. From the taking of one assise sometimes one conviction [030] follows, sometimes two, as is evident, according as the jurors give to or take away [031] from one party the entire thing the plaintiff has put in his view or part of what he has [032] put in his view. If the jurors, where they ought to have given or taken away the whole, [033] give or take away part,4 two convictions follow, as may be seen by an example. A. [034] puts two carucates of land in his view
