1Macer, On Appeals, Book II. We must remember that when an inquiry is made whether a case has been decided or not, and the judge of this question declares that it has not been decided, even though it may have been, it is rescinded, even if no appeal has been taken. 1Ad Dig. 49,8,1,1ROHGE, Bd. 7 (1873), S. 59: Berichtigung von Rechnungsfehlern in einem Erkenntnisse.Likewise, if an error in the calculation is alleged to exist in the decision, it is not necessary to appeal, for instance, if the judge decides as follows: “As it is proved that Titius owes Seius fifty sesterces for such-and-such an article, and also twenty-five for another; therefore I hold that Lucius Titius shall pay Seius a hundred sesterces;” because, as the mistake is one of computation, it is not necessary to appeal, and it can be corrected without doing so. If, however, the judge of this question should render a decision for a hundred sesterces, for the reason that he thought that fifty and twenty-five made a hundred, still, the same mistake is one of computation, and it is not necessary to appeal. But when the judge decides that there is another sum of twenty-five sesterces due, there will be ground for appeal. 2Likewise, when the decision is contrary to the Imperial Constitutions, the necessity for appeal does not exist. A decision is rendered against the constitutions when it is pronounced in compliance with the law as laid down by them, and not with reference to the rights of the litigant; for if the judge, in the case of a person desiring to be excused from the charge of a public office, or of a guardianship, on account of having children, or through age, or by reason of some privilege, should hold that neither children, nor age, nor any privilege will avail to excuse anyone from office, or from guardianship, he is understood to have decided with reference to the law as set forth in the constitutions. If, however, he should permit a person to establish his right, and then renders a decision against him because he did not prove his age, or the number of his children; he is understood to have decided with reference to the rights of the litigant, in which case an appeal will be necessary. 3Likewise when, under a peremptory Edict which has not been published, and of which the party has not been notified, he is convicted while absent, the constitutions declare that a decision of this kind is of no effect. 4If you and I both apply to the same judge, and neither of our petitions asks for interest, and the judge renders a decision against me before doing so against you, in order that you may be the first to have a judgment in your favor; it is not necessary for me to appeal on this ground, as, according to the Sacred Constitutions, you cannot ask for an execution against me before judgment has been rendered with reference to my claim; but the better opinion is that an appeal should be taken.

2Paulus, Opinions, Book III. Paulus held that he who was not alive at the time when judgment was rendered against him is understood to have been condemned to no purpose. 1He also held with reference to a person who was not alive at the time when the judge was appointed to decide his case that the appointment of the judge was void, and any decision rendered against him would be of no force or effect.

3The Same, Opinions, Book XVI. Paulus gave it as his opinion that a judicial order which is impossible was void. 1He also gave it as his opinion, that there was no ground for appeal where a decision had been rendered, which, in the nature of things, could not be complied with.
