In November 2005 the Court of Appeal referred 10 questions to the ECJ in this case. An Advocate-General has now given his (non-binding) opinion to the effect that the eventual ECJ judgment should support union action to dissuade employers from relocating to another part of the EU to benefit from lower wage costs. In a separate (Swedish) case on the same day a different Advocate-General suggested that it can generally be lawful for a trade union to take action to compel firms supplying workers from one EU country to another to pay domestic rates of pay.
