Official Languages Act 2003
Administration of justice.
8. —(1) A person may use either of the official languages in, or in any pleading in or document issuing from, any court.
(2) Every court has, in any proceedings before it, the duty to ensure that any person appearing in or giving evidence before it may be heard in the official language of his or her choice, and that in being so heard the person will not be placed at a disadvantage by not being heard in the other official language.
(3) For the purposes of ensuring that no person is placed at a disadvantage as aforesaid, the court may cause such facilities to be made available, as it considers appropriate, for the simultaneous or consecutive interpretation of proceedings from one official language into the other.
(4) Where the State or a public body is a party to civil proceedings before a court—
(a) the State or the public body shall use in the proceedings, the official language chosen by the other party, and
(b) if two or more persons (other than the State or a public body) are party to the proceedings and they fail to choose or agree on the official language to be used in the proceedings, the State or, as appropriate, the public body shall use in the proceedings such official language as appears to it to be reasonable, having regard to the circumstances.
(5) Notwithstanding any other provision of this section, a person shall not be compelled to give evidence in a particular official language in any proceedings.
(6) In choosing to use a particular official language in any proceedings before a court, a person shall not be put by the court or a public body to any inconvenience or expense over and above that which would have been incurred had he or she chosen to use the other official language.
