ZONDI AJ [22] Rule 31 of this Court‘s Rules permits any party to any proceedings before the Court including a properly admitted amicus curiae ―to canvass factual material which is relevant to the determination of the issues before the Court and which does not specifically appear on the record‖ provided that ―such facts are common cause or otherwise incontrovertible; or are of an official, scientific, technical or statistical nature capable of easy verification‖. [23] This Court in Prince held that, where the new evidence sought to be canvassed is disputed, it undoubtedly demonstrates that the new evidence is not ―capable of easy verification‖ and similarly is not incontrovertible.14 [24] The evidence which the WLC seeks to introduce should be admitted. None of the parties objected to its admission. The new evidence, which is entirely uncontested, sets out the effect of rape trauma on adult survivors reporting sexual assault and getting support thereafter. It is the only evidence we have that relates to adult trauma syndrome. The findings of this Court on the nature and extent of rape trauma syndrome would be a welcome addition to this Court‘s jurisprudence since its judgment in Bothma.15 Moreover in order to consider the full extent of the impact of section 18, and whether it serves an important public interest, it is necessary to have information on the prevalence of sexual offences against women in South Africa and the percentage of female survivors of sexual offences who elect not to formally report the offences to the South African Police Service (SAPS) and why they do not do so. This is what the new evidence seeks to highlight. For instance the new evidence shows that in the ―Victims of Crime Survey 2015/2016‖, a report by Statistics South Africa, only 35.5 percent of survivors reported sexual offences to SAPS, which is quite alarming.16 Failure to report 14 Prince v President, Cape Law Society of the Cape of Good Hope [2002] ZACC 1; 2002 (2) SA 794 (CC); 2002 (3) BCLR 231 (CC) at para 10.
