[ULPIANUS libro decimo ad edictum. ] §3.5.9.prSed an ultro mihi tribuitur actio sumptuum quos feci? et puto competere, nisi specialiter id actum est, ut neuter aduersus alterum habeat actionem.
[ULPIAN, on the Edict, book ten] But is an action furthermore granted to me for the expenses which I incurred? And I think it is competent, unless it was specifically agreed that neither should have an action against the other.
§3.5.9.1Is autem qui negotiorum gestorum agit non solum si effectum habuit negotium quod gessit, actione ista utetur, sed sufficit, si utiliter gessit, etsi effectum non habuit negotium.
Moreover, he who sues on business managed will use that action not only if the business he managed achieved its effect, but it is sufficient if he managed it usefully, even if the business did not achieve its effect.
et ideo si insulam fulsit uel seruum aegrum curauit, etiamsi insula exusta est uel seruus obit, aget negotiorum gestorum: idque et Labeo probat.
And therefore, if he supported a block of flats or treated a sick slave, even if the block of flats was burnt down or the slave died, he will bring the action on business managed; and this Labeo also approves.
sed ut Celsus refert, Proculus apud eum notat non semper debere dari.
But as Celsus reports, Proculus notes in his commentaries on Labeo that it ought not always to be granted.
quid enim si eam insulam fulsit, quam dominus quasi impar sumptui dereliquerit, uel quam sibi necessariam non putauit? onerauit, inquit, dominum secundum Labeonis sententiam, cum unicuique liceat et damni infecti nomine rem derelinquere.
For what if he supported a block of flats which the owner had abandoned as being unequal to the expense, or which he did not think necessary for himself? He burdened the owner, he says, according to Labeo's opinion, whereas everyone is permitted to abandon a thing on account of threatened damage.
sed istam sententiam Celsus eleganter deridet: is enim negotiorum gestorum, inquit, habet actionem, qui utiliter negotia gessit: non autem utiliter negotia gerit, qui rem non necessariam uel quae oneratura est patrem familias adgreditur.
But Celsus elegantly derides this opinion; for he says that he has the action on business managed who has managed business usefully; but he does not manage business usefully who undertakes a matter that is unnecessary or which will burden the head of the family.
iuxta hoc est, quod Iulianus scribit, eum qui insulam fulsit uel seruum aegrotum curauit, habere negotiorum gestorum actionem, si utiliter hoc faceret, licet euentus non sit secutus.
In line with this is what Julian writes, that he who supported a block of flats or treated a sick slave has the action on business managed if he did this usefully, although the event did not follow.
ego quaero: quid si putauit se utiliter facere, sed patri familias non expediebat? dico hunc non habiturum negotiorum gestorum actionem: ut enim euentum non spectamus, debet utiliter esse coeptum.
I ask: what if he thought he was doing it usefully, but it was not expedient for the head of the family? I say that he will not have the action on business managed; for just as we do not look at the event, it must have been begun usefully.
