What's your opinion on this UK ruling involving gender and sexuality?

This article discusses a case in which a defendant was sentenced by a court in England to three years in prison and ordered to register as a sex offender for life as a result of the relationship in which she represented herself as male (I use “she” since the article states that the defendant self-identifies as female).

I find the decision questionable at best, but when I read that “Previous U.K. cases have found that concealing one’s marital status, wealth, age or HIV diagnosis from a sexual partner does not invalidate consent.”, that pretty much renders the entire case moot in my opinion.

Are there arguments that would put this in a non-homophobic, non-transphobic light?
