Quite a worrying story.
BBC NEWS | UK | Magazine | When does kinky porn become illegal?
The new law will outlaw pornography featuring any of the following:
- An act which threatens or appears to threaten a person's life
- An act which results in or appears to result in serious injury to a person's anus, breasts or genitals
- An act which involves or appears to involve sexual interference with a human corpse
- A person performing or appearing to perform an act of intercourse or oral sex with an animal
The most worrying part is in the explanitory notes for the bill which state that if an act is sufficiently extreme a judge can decide that, even if the participants consented, such consent is not valid in the eyes of the law and the activity is illegal.
For example, if you engage in consensual knife/cutting-play a judge can decide that because in his eyes a "reasonable" person would not consent to such activity that your or your partner's consent is not legally valid.
Mental.
