@Croak: Brace yourself - I'm about to agree with you, at least to some extent.
Those articles are interesting - both from a general perspective, and to me personally as a legal scholar. Since you have got me thinking about this matter, I also came upon this article which you may find interesting:
http://www.concordatwatch.eu/topic-47562.843
Sharia "courts", like the Jewish religious "courts" which also exist in the UK, are of course not proper courts of law and it is important to understand that their rulings will generally not have legal force (nor should they - we are a secular country with a well-developed legal system).
However, it is a matter of concern, set out particularly clearly in the study by the Dutch academic quoted in the Independent article you linked, if people from the Muslim community here in the UK are being misled by these "courts" into believing that they have the ability to make binding judgements. There appears to be a particular concern that Muslim women are being told they need the approval of a Sharia "court" to get divorced - which of course is not actually the case. They should in fact bring divorce proceedings through the proper courts.
There seems to be a conflict here between having religious and cultural tolerance, on the one hand, and ensuring that the human rights of citizens, and more generally the rule of law, are upheld.
If it is the case that women from the Muslim community are being denied their human rights and, for example, being denied access to lawful divorce proceedings, then that would indeed be very worrying and something should be done about it.
It would appear that one British lawmaker, Baroness Cox, is attempting to do something about it. She has introduced a Bill called the Arbitration and Mediation Services (Equality) Bill. It appears the primary intention of this Bill is to ensure that religious courts (and other bodies) are prohibited from passing themselves off as legitimate providers of legal arbitration services when, in fact, they come nowhere near the standard required of such an arbitrator.
Information on the Bill is here:

I am inclined to hope that Baroness Cox will be successful and this may become law in future.
