[IDEM libro septimo quaestionum. ] §45.1.64.prHuiusmodi stipulatio interposita est: 'si Titius consul factus fuerit, tum ex hac die in annos singulos dena dari spondes?' post triennium condicio exstitit: an huius temporis nomine agi possit, non immerito dubitabitur.
[THE SAME, Questions, Book 7] A stipulation of this kind was entered into: 'If Titius should be made consul, do you promise that ten shall be given every year from this day?' After three years the condition was fulfilled: it will not without reason be doubted whether an action can be brought on account of this period.
respondit eam stipulationem utilem esse ita, ut in ea eorum quoque annorum, qui ante impletam condicionem intercesserint, praestatio in id tempus collata intellegatur, ut sententia eius sit talis: tunc cum Titius consul factus fuerit, in annos singulos, etiam praeteriti temporis habita ratione, dena praestentur.
He answered that the stipulation is valid in such a way that in it the payment also of those years which elapsed before the fulfillment of the condition is understood to be deferred to that time, so that its meaning is as follows: then when Titius shall have been made consul, ten shall be paid for each year, taking into account also the past time.
