It took a ten year battle with the Labour Party before Raghib won. Guido has not noticed this well reported elsewhere. The full Law Lords ruling is here [pdf].
Lord Hoffman was absolutely damning of the Labour Party defence proffered, before he resigned, by Peter Watt -
…it seems to me unacceptable. It is nothing more than the old plea that you have nothing against employing a black person but the customers would not like it. In essence it is a defence of justification based on political expediency. It may salvage the purity of the personal motives of the selection panel but it does not in my opinion satisfy the terms of the 1976 Act, which does not allow any justification for “direct” discrimination. It simply says that one shall not discriminate on racial grounds.
