@stgeorge no need to work any thing out. in the uk the justice system is carried in the name of the queen.
all prosecutions are in her name... she is above it all.
so its an impossibility... interesting... uh?
so an actions that can be considered repugnant... lets say she killed the child afterwards.... still she wouldnt face presecution... and all the people in the uk are under that arrangement.
lets say the prince did the horrible did of having sex with that cutie when she was 15 and 11 months... then he gets prosecuted and convicted.... the queen has the authority to pardon him... and anybody she wants... so what was considered a crime can be absolved if the soverigns wishes so.
i think the criminalization of sexual activities are absurd. but thats the world we live right now
