21 * * * 50. The technical opinion that Mr. Bernales Ballesteros provided to the Commission was not challenged by the State; therefore, this Court, pursuant to the powers granted it by article 44 of its Rules of Procedure, considers it useful and incorporates it into the probative material as documentary evidence. 51. The documentation that the Commission submitted during the public hearing on merits included documents about supervening events dated after the application11 and, based on Article 43 of its Rules of Procedure, the Court decides to incorporate them into the probative evidence. 52. All but two of the newspaper clippings submitted by the Commission with its arguments on expenses and costs had already been submitted during the public hearing on merits (supra 38); accordingly, it is not necessary to include them in the probative evidence. 53. Furthermore, this Court has considered that, even though they are not really documentary evidence, the newspaper clippings submitted by the Commission (supra 37, 38 and 41) can be evaluated when they deal with well-known or public facts or statements made by State officials, or when they corroborate the contents of other documents or testimonies received during the proceeding12. Therefore, the Court adds them to the probative material as an appropriate means of verifying the truth of the facts of the case, in conjunction with the other evidence. 54. The documents submitted by the Commission during the merits stage were not contested or challenged, nor were any questions raised about their authenticity; therefore, the Court considers them to be valid. 55. The 1979 and 1993 Constitutions of Peru, the rules of procedure of the Congress of the Republic of Peru, published in the official gazette, El Peruano, on May 30, 1998 (supra 40), Law No. 26,301 promulgated on April 18, 1994, and published in the official gazette, El Peruano, on May 3, 1994, Law No. 26,430 published in the official gazette, El Peruano, on January 7, 1995, Law No. 23,506 (Habeas Corpus and Amparo Law), published in the official gazette, El Peruano, on December 8, 1982, and the evidence on expenses and costs submitted by the Commission are considered useful for deciding the instant case and are added to the probative evidence, pursuant to the provisions of Article 44(1) of the Rules of Procedure.
