Oh yes there is no doubt that the BCA have been defamed. It's just that as it stands Simon would have been in an excelent position to justify this defamation.
You see according to
Jack of Kent all defamation means is that the publication of the passage complained of, has lowered the reputation of the BCA. The Court of Appeal couldn't very well say that the article's publication has had no negative effect on the reputation of the BCA, that would be absurd.
Thanks partly to the words Simon wrote and even more to the BCA's efforts in bringing them to the widest possible readership their reputation is now hugely damaged. Everyone who is anyone knows that they've been happily promoting bogus treatments for which there's not a jot of evidence.
The courts haven't denied that this is bad news for the BCA, they've just opened a big wide door marked "Just as it should be" and invited Simon to step through it.
