Personally, I think that Mr Brown should give up now. The judgment is well reasoned and clear, and it reflects both the legislation and the intention behind it (both are important). Having read the judgment and relevant legislation, I suspect than an appeal will be futile.
Personally, the Judges view is well reasoned and clear but the judgement is flawed being based on what BW has invented over the years rather than law. An appeal is hardly likely to reverse everything but it may do better at actually clarifying what is legal. Else it looks like there will be more lime green boats.
