49 Court’s power to exclude evidence under other laws Nothing in this Act shall limit any power a court may have under any other law to exclude or refuse to allow the giving of any evidence, whether by preventing the questioning of a witness or by refusing to allow the production of any thing or otherwise. 50 Court may examine evidence to deter admissibility or existence of privilege (1) For the purpose of determining whether or not any statement, matter or thing is or should be admissible in evidence or privileged from disclosure in terms of this Act, a court shall be entitled, but not obliged— (a) to examine the statement, matter or thing; and (b) to hear evidence or receive information concerning the statement, matter or thing or concerning its admissibility; and may make such order in respect thereof as the court considers appropriate. (2) If it is appropriate in the circumstances to do so, a court may conduct any examination or hear any evidence in terms of subsection (1) in private and may take such other steps as the court considers necessary to limit publication of the proceedings or disclosure of the statement, matter or thing concerned, whether in terms of the Courts and Adjudicating Authorities (Publicity Restriction) Act [Chapter 7:04] or otherwise. 51 Court not obliged to believe any evidence The fact that any evidence is rendered admissible by this Act shall not oblige the court to believe it or to rely on it. 52 Decision may be based on evidence of single witness Subject to any other law, a court may make a finding and base its decision on the evidence of a single competent and credible witness. 53 Power to take evidence on commission not limited by Act Nothing in this Act shall be construed as limiting the power of a court under any other enactment to order or allow the evidence of a witness to be taken on commission, nor as rendering any such evidence inadmissible. 54 Evidence admissible under more than one provision of Act Subject to section forty-four, where any evidence is rendered admissible in terms of two or more provisions of this Act, it may be admitted under any of those provisions. 55 Interpreters (1) Where a witness is unable to give evidence in the language in which the proceedings are being held, the party calling him as a witness shall cause him to be provided with the services of a properly qualified interpreter, approved by the court, to translate his evidence into that language. (2) Subject to rules of court, the court shall cause to be administered to an interpreter provided in terms of subsection (1) such oath as the court considers suitable for the occasion. (3) Subject to rules of court, the reasonable costs of an interpreter provided in terms of subsection (1) shall be allowed in the taxation of any costs that are awarded by the court. 56 Cases not provided for in Act Where an issue as to the admissibility of any evidence or the competence or compellability of any witness arises which is not provided for in this Act, the issue shall be determined according to the law applicable in similar cases before the Supreme Court of Judicature in England: Provided that nothing in this section shall give effect with Zimbabwe to any enactment passed by the Parliament of the United Kingdom after the 1st June, 1927.
