Times of London:

ISLAMIC law has been officially adopted in Britain, with sharia courts given powers to rule on Muslim civil cases.

The government has quietly sanctioned the powers for sharia judges to rule on cases ranging from divorce and financial disputes to those involving domestic violence. 

So what happens when a Muslim tries to sue a non-muslim in a sharia court?

Or maybe the guy who converts before a divorce, because sharia law favors men…

Or the fact that women just get the short end of just about everything…

Even leaving out the inherent troubles with sharia law, any time where you have 2 standards of justice, you are asking for trouble.
