[CELSUS libro trigesimo quarto digestorum. ]
[CELSUS, in the thirty-fourth book of the digests.] If either this or that is bequeathed, there is only one bequest.
§31.0.27.prSi illud aut illud legatum sit, unum legatum est. si sub contrariis condicionibus aliud atque aliud legatum est, unum legatum esse arbitramur.
If different things are bequeathed under contrary conditions, we consider that there is only one bequest.
neque refert et heredum et eorum quibus legatum est diuersas personas esse, ueluti si ita legatum est: 'si Nerua consul factus erit, Titius heres Attio fundum, si non erit Nerua consul factus, Seius heres Maeuio centum dato'.
And it makes no difference that the persons of both the heirs and those to whom the bequest is made are different, as for example, if it is bequeathed thus: 'If Nerva should be made consul, let Titius as heir give the land to Attius; if Nerva should not be made consul, let Seius as heir give one hundred to Maevius.'
