Canon 1600. Only in the following situations can the judge, after the conclusion of the case, still recall earlier witnesses or call new ones, or make provision for other evidence not previously requested:

1° in cases in which only the private good of the parties is involved if all the parties agree;

2° in other cases, provided that the parties have been consulted, that a grave reason exists, and that all danger of fraud or subornation is removed;

3° in all cases, whenever it is probable that, unless new evidence is admitted, the judgement will be unjust for any of the reasons mentioned in can. 1645 §2, nn. 1-3.

§2 The judge can, however, command or permit the presentation of a document which, even without fault of the interested party, could not be presented earlier.

§3 New evidence is to be published according to can. 1598 §1.

§1. Post conclusionem in causa iudex potest adhuc eosdem testes vel alios vocare aut alias probationes, quae antea non fuerint petitae, disponere tantummodo:

1° in causis, in quibus agitur de solo privato partium bono, si omnes partes consentiant;

2° in ceteris causis, auditis partibus et dummodo gravis exstet ratio itemque quodlibet fraudis vel subornationis periculum removeatur;

3° in omnibus causis, quoties verisimile est, nisi probatio nova admittatur, sententiam iniustam futuram esse propter rationes, de quibus in can. 1645, §2, nn. 1-3.

§2. Potest autem iudex iubere vel admittere ut exhibeatur documentum, quod forte antea sine culpa eius cuius interest, exhiberi non potuit.

§3. Novae probationes publicentur, servato can. 1598, §1.
