Finally we have to treat of the duties of a judge; of which the first is not to judge contrary to statutes, the imperial laws, and custom.

1 Accordingly, if he is trying a noxal action, and thinks that the master ought to be condemned, he should be careful to word his judgement thus: 'I condemn Publius Maevius to pay ten aurei to Lucius Titius, or to surrender to him the slave that did the wrong.'

2 If the action is real, and he finds against the plaintiff, he ought to absolve the defendant; if against the latter, he ought to order him to give up the property in question, along with its fruits. If the defendant pleads that he is unable to make immediate restitution and applies for execution to be stayed, and such application appears to be in good faith, it should be granted upon the terms of his finding a surety to guarantee payment of the damages assessed, if restitution be not made within the time allowed. If the subject of the action be an inheritance, the same rule applies as regards fruits as we laid down in speaking of actions for the recovery of single objects. If the defendant is a mala fide possessor, fruits which but for his own negligence he might have gathered are taken into account in much the same way in both actions; but a bona fide possessor is not held answerable for fruits which he has not consumed or has not gathered, except from the moment of the commencement of the action, after which time account is taken as well of fruits which might have been gathered but for his negligence as of those which have been gathered and consumed.

3 If the object of the action be production of property, its mere production by the defendant is not enough, but it must be accompanied by every advantage derived from it; that is to say, the plaintiff must be placed in the same position he would have been in if production had been made immediately on the commencement of the action. Accordingly if, during the delay occasioned by trial, the possessor has completed a title to the property by usucapion, he will not be thereby saved from being condemned. The judge ought also to take into account the mesne profits, or fruits produced by the property in the interval between the commencement of the action and judgement. If the defendant pleads that he is unable to make immediate production, and applies for a stay, and such application appears to be in good faith, it should be granted on his giving security that he will render up the property. If he neither complies at once with the judge's order for production, nor gives security for doing so afterwards, he ought to be condemned in a sum representing the plaintiff's interest in having production at the commencement of the proceedings.

4 In an action for the division of a 'family' the judge ought to assign to each of the heirs specific articles belonging to the inheritance, and if one of them is unduly favoured, to condemn him, as we have already said, to pay a fixed sum to the other as compensation. Again, the fact the one only of two jointheirs has gathered the fruits of land comprised in the inheritance, or has damaged or consumed something belonging thereto, is ground for ordering him to pay compensation to the other; and it is immaterial, so far as this action is concerned, whether the jointheirs are only two or more in number.

5 The same rules are applied in an action for partition of a number of things held by joint-owners. If such an action be brought for the partition of a single object, such as an estate, which easily admits of division, the judge ought to assign a specific portion of each jointowner, condemning such one as seems to be unduly favoured to pay a fixed sum to the other as compensation. If the property cannot be conveniently divided—as a slave, for instance, or a mule—it ought to be adjudged entirely to one only of the jointowners, who should be ordered to pay a fixed sum to the other as compensation.

6 In an action for rectification of boundaries the judge ought to examine whether an adjudication of property is actually necessary. There is only one case where this is so; where, namely, convenience requires that the line of separation between fields belonging to different owners shall be more clearly marked than heretofore, and where, accordingly, it is requisite to adjudge part of the one's field to the owner of the other, who ought, in consequence, to be ordered to pay a fixed sum as compensation to his neighbour. Another ground for condemnation in this action is the commission of any malicious act, in respect of the boundaries, by either of the parties, such as removal of landmarks, or cutting down boundary trees: as also is contempt of court, expressed by refusal to allow the fields to be surveyed in accordance with a judge's order.

7 Wherever property is adjudged to a party in any of these actions, he at once acquires a complete title thereto.
