It is impossible to reconcile this antiquated "law" with English law, so what could Lord Phillips mean when he says that Sharia law can be used in Muslim communities as long as such laws comply with English law? This will mean English law must become subordinate to Sharia law. This is Dhimmitude, an Islamic system of religious apartheid begun in the 7th century that forces all other religions and cultures to accept an inferior status once Muslims become the majority.
Maryland's Court of Appeals recently denied a Sharia divorce to a Pakistani man. The man's wife of 20 years had filed for divorce. To circumvent having to share their $2 million estate and other marital assets, he went to the Pakistani embassy and applied for an Islamic divorce. The man wanted to invoke what is known as talaq, in which the husband says, "I divorce you" three times and it's done.
The Maryland court said, "If we were to affirm the use of talaq, controlled as it is by the husband, a wife, a resident of this state, would never be able to consummate a divorce action filed by her in which she seeks a division of marital property" and the talaq "directly deprives the wife of the due process she is entitled to when she initiates divorce litigation. The lack and deprivation of due process is itself contrary to (Maryland's) public policy."
British Muslims who wish to live under Sharia law might have stayed in the countries from which they came - or return to them. But their objective appears to be domination of England, not assimilation. This also seems to be the goal for Muslims in other countries with large and growing Muslim populations.
There is no due process under Sharia law. Lord Phillips has signed the death warrant for his nation if his opinion becomes the law of England. It's one thing to fight a war and lose it. It's quite another to willingly surrender without a struggle.
