(1) This rule applies where under these Rules an oath is required to be administered to a person. (2) Sections 1 and 3 to 6 of the Oaths Act 1978 shall apply, as modified by paragraph (3), as they would apply if the person were required to take an oath in England and Wales. (3) Where section 1 or 6 of that Act applies by virtue of this rule, the reference in that section to the words of the oath prescribed by law is to be read as a reference to the words prescribed by Schedule 1 for a person of the class to which the person belongs.
