Stef sez, The British Chiropractic Association is using the libel laws to try and silence Simon Singh's discussion of some of the more, uh, unusual claims they make for Chiropractic treatments (such as curing Colic and Asthma).
They've sued Simon for libel for describing such claims as 'bogus', and in a preliminary hearing a judge has chosen a somewhat odd, harder to defend, definition of the word, even though Simon clarified his precise meaning in the very same article.
Dave Gorman has a good summary, and there's a lot more detail at Jack of Kent."
(Thanks, Stef!)
