"In the sensitive and specific context of domestic abuse, the position, in our opinion, is very different to that advocated for by [counsel for Mr Barton]. It is that it will often not be unfair to allow the prosecution to adduce the res gestae evidence of a complainant where they are not called as a witness, and there is an absence of fear. As is now well understood it is not uncommon in such cases for there to be sufficient evidence to prosecute the alleged perpetrator of the abuse even where the complainant does not to support the prosecution. In our opinion, in such cases, the public interest may often demand the use of res gestae evidence, particularly recorded evidence, regardless of the cooperation of the complainant."
