Only if both parties agree to use this form of Arbitration.By very nature, Sharia violates the basic notion of equal protection under the law, because a woman's testimony is regarded as less than a man's.
As is any contractual obligation. If you agree to abide by it.Also, you are not telling the truth about the legality of such sharia court decisions in Britain. They ARE legally binding.
From my article:
In 1996, Parliament passed the Arbitration Act setting out rules under which parties in a dispute have the right to go to an impartial tribunal to get justice without expensive litigation. Muslims lawyers interpreted this as meaning that sharia courts could act as arbitration panels under the Act, they began in 2007, and their decisions are legally binding.
It bears mentioning that just in any form of arbitration, there is always recourse to the Court.
