A MOTORCYCLE club had a rule that its members were not allowed to wear their colours while having sex with Aboriginal women, documents filed in the Northern Territory Supreme Court show.

The rules of the Blonks Motorcycle Club, filed with the NT's Registrar of Associations, stipulated that "due to past circumstances no colours to be worn when shafting gins and no gins to be brought to the house ever".

The term "gin" to describe an indigenous woman is highly offensive to Aborigines.

The club's rules were filed in the NT Supreme Court in an application by club member Paul Anthony Johnson to overturn an order of the NT Commissioner of Consumer Affairs that dissolved the club and seized its clubhouse and land.

The rules stipulated that "in the interests of peace among members, keep your hands off another woman if she is a member's woman".
