In deciding what is in public interest, the courts have made some decisions that are difficult to reconcile- in r v wilson, it was decided that where a defendant branded his initials on his wife's buttocks with a hot knife at her request, this is not unlawful-- even if she had to seek medical attention. Here, it was held that it was not in the public interest that consensual behavior of this kind should be criminalized, as this was an issue of personal adornment like a tattoo.
