Yea, my memory and posting when drinking. it was actually 14yr old so old enough for consent (at the time), the case was in the BC Supreme court and was more of a reference case on the Constitutionality of Canada's polygamy laws.
The real problem is/was getting enough evidence to prosecute for sexual abuse. To quote the special prosecutor,
