From the article -

Their rulings include statements condemning homosexuals to harsh beatings and ordering a wife to have sex with her husband "even if she is busy in the kitchen" at the time.

and then -

Decisions made by religious tribunals are legally binding and can be enforced in county courts and the high court if both parties have agreed to be ruled by sharia.

Er, really?

and later -

"The reality is that for many Muslims, sharia courts are in practice part of an institutionalised atmosphere of intimidation, backed by the ultimate sanction of a death threat."

British courts are enforcing death threats?

I feel the article lacks credibility.
