THE TRUSTWORTHINESS OF TESTIMONIES
Can. 1572 In evaluating testimony, the judge, after having requested testimonial letters if necessary, is to consider the following:
1/ what the condition or reputation of the person is;
2/ whether the testimony derives from personal knowledge, especially from what has been seen or heard personally, or whether from opinion, rumor, or hearsay;
3/ whether the witness is reliable and firmly consistent or inconsistent, uncertain, or vacillating;
4/ whether the witness has co-witnesses to the testimony or is supported or not by other elements of proof.
Can. 1573 The testimony of one witness cannot produce full proof unless it concerns a qualified witness making a deposition concerning matters done ex officio, or unless the circumstances of things and persons suggest otherwise.
