Extensive interpretation of race discrimination by UK courts

It is no secret that nationals from countries where their employer is domiciled often do - or at least appear to - get preferential treatment from their respective employers. This applies to banks and other financial institutions irrespective of their country of origin. This may well be considered unfair by some observers but could on the other hand be justified to some extent. How many Europeans working for a Japanese bank for example are fully conversant with the Japanese Language? And in the future we will have a tough time to find many seasoned professionals able to express themselves fluently in Mandarin, Russian or Arabic. So we noticed with quite some bewilderment that an English court can use legislation intended to fight race discrimination when sitting in judgement about an compensation claim by an English employee working for a French bank here in London. If the Gold Standard would have to be applied in every decision concerning promotion it would mean that in nearly every case the employee who loses out would have a case to sue. In addition, who determines which employee merits promotion more? Should every decision have to be submitted to a court or tribunal before it becomes effective? Politicians, the Courts and pressure groups all combine to make the UK a less efficient and less inviting place to locate a business and court cases such as this one are the worst possible advertisement for UK Plc.
