15 subject to the formalities required for testimonial evidence. However, their probative weight depends on whether they corroborate or refer to aspects of the specific case.36 Consequently, and given the general nature of the State’s opposition, the Court decides to admit them and will assess them, were appropriate, taking into account the body of evidence, the observations of the State, and the rules of sound judicial discretion. 35. Regarding the newspaper articles forwarded by the representatives, this Court has found that they may be assessed when they refer to well-known public facts or statements made by State officials,37 or when they corroborate aspects of the case.38 The Court has verified that it is not possible to distinguish the date of publication of some of these documents. Nevertheless, none of the parties objected to the documents on this basis or questioned their authenticity. The Court decides to admit the documents that are complete or that, at least, allow their source and date of publication to be determined, and will assess them taking into account the body of evidence, the State’s observations, and the rules of sound judicial discretion. 36. Likewise, the Court adds other documents to the body of evidence, in application of Article 47(1) of the Court Rules of Procedure, because it deems them useful to the resolution of this case.39 37. On the other hand, with regard to the documents provided by the representatives and the State following the submission of the brief on pleadings and motions and the brief in response to the application, respectively, the Court finds it opportune to recall that Article 46 of the Rules of Procedure, which regulates the admission of evidence, establishes: 1. Items of evidence tendered by the parties shall be admissible only if they are offered in the application of the Commission, in the pleadings, motions and evidence of the alleged victims, in the answer to the application and observations to the pleadings and motions filed by the State or, when appropriate, in the document setting out the preliminary objections and the answer thereto.
