This is a case of sado-masochism where the group of men were engaged in act of violence against each other particularly on their genital parts, by branding or genital torture for sexual pleasure. The victims in each case consented to this ritual (activity) and didn't suffer any permanent injury. Each of the defendants faced assault ABH charges and unlawful wounding.

While in the case of R V brown the evidence showed that use of alcohol and drugs were employed to get consent. The victims were bound so the sadists could
