(c) To be tried without undue delay;
(d) Subject to article 63, paragraph 2, to be present at the trial, to conduct the defence in person or through legal assistance of the accused's choosing, to be informed, if the accused does not have legal assistance, of this right and to have legal assistance assigned by the Court in any case where the interests of justice so require, and without payment if the accused lacks sufficient means to pay for it;
(e) To examine, or have examined, the witnesses against him or her and to obtain the attendance and examination of witnesses on his or her behalf under the same conditions as witnesses against him or her. The accused shall also be entitled to raise defences and to present other evidence admissible under this Statute;

(i) Not to have imposed on him or her any reversal of the burden of proof or any onus of rebuttal.
2. In addition to any other disclosure provided for in this Statute, the Prosecutor shall, as soon as practicable, disclose to the defence evidence in the Prosecutor's possession or control which he or she believes shows or tends to show the innocence of the accused, or to mitigate the guilt of the accused, or which may affect the credibility of prosecution evidence. In case of doubt as to the application of this paragraph, the Court shall decide.
Article 69. Before testifying, each witness shall, in accordance with the Rules of Procedure and Evidence, give an undertaking as to the truthfulness of the evidence to be given by that witness.
The testimony of a witness at trial shall be given in person, except to the extent provided by the measures set forth in article 68 or in the Rules of Procedure and Evidence.
Evidence obtained by means of a violation of this Statute or internationally recognized human rights shall not be admissible if:
(a) The violation casts substantial doubt on the reliability of the evidence; or
(b) The admission of the evidence would be antithetical to and would seriously damage the integrity of the proceedings.
Article 72. If a State learns that information or documents of the State are being, or are likely to be, disclosed at any stage of the proceedings, and it is of the opinion that disclosure would prejudice its national security interests, that State shall have the right to intervene in order to obtain resolution of the issue in accordance with this article.
If the Court determines that the evidence is relevant and necessary for the establishment of the guilt or innocence of the accused, the Court may undertake the following actions:
(a) Where disclosure of the information or document is sought pursuant to a request for cooperation under Part 9 or the circumstances described in paragraph 2, and the State has invoked the ground for refusal referred to in article 93, paragraph 4:
(i) The Court may, before making any conclusion referred to in subparagraph 7 (a) (ii), request further consultations for the purpose of considering the State's representations, which may include, as appropriate, hearings in camera and ex parte;
(ii) If the Court concludes that, by invoking the ground for refusal under article 93, paragraph 4, in the circumstances of the case, the requested State is not acting in accordance with its obligations under this Statute, the Court may refer the matter in accordance with article 87, paragraph 7, specifying the reasons for its conclusion; and
(iii) The Court may make such inference in the trial of the accused as to the existence or non-existence of a fact, as may be appropriate in the circumstances; or
(b) In all other circumstances:
(i) Order disclosure; or
(ii) To the extent it does not order disclosure, make such inference in the trial of the accused as to the existence or non-existence of a fact, as may be appropriate in the circumstances.
Article 74. All the judges of the Trial Chamber shall be present at each stage of the trial and throughout their deliberations. The Presidency may, on a case-by-case basis, designate, as available, one or more alternate judges to be present at each stage of the trial and to replace a member of the Trial Chamber if that member is unable to continue attending.
The Trial Chamber's decision shall be based on its evaluation of the evidence and the entire proceedings. The decision shall not exceed the facts and circumstances described in the charges and any amendments to the charges. The Court may base its decision only on evidence submitted and discussed before it at the trial.
Article 76. In the event of a conviction, the Trial Chamber shall consider the appropriate sentence to be imposed and shall take into account the evidence presented and submissions made during the trial that are relevant to the sentence.
The sentence shall be pronounced in public and, wherever possible, in the presence of the accused.
