If evidence of a cultural or customary nature is to be given by way of singing, dancing, storytelling or in any way other than in the normal course of giving evidence, the party seeking to adduce the evidence must tell the Court, within a reasonable time before the evidence is proposed to be given:
(a) where, when and in what form it is proposed to give the evidence; and
(b) of any issues of secrecy or confidentiality relating to the evidence or part of the evidence.
