Journalists, scientists and even a Liberal Democrat Member of Parliament met in a pub last night in support of science writer Simon Singh, who is fighting a libel case brought by the British Chiropractic Association, which Nature covered two weeks ago and last week.

The 7 May ruling, in which Justice David Eady spelled out how he would interpret Singh’s article if the case goes forward, will make it difficult for Singh to defend himself in a full trial.

The Skeptics Club, which meets at the Penderels Oak pub in London, invited speakers including comedian Dave Gorman, journalist Nick Cohen, and Lib Dem Dr. Evan Harris. The speakers decried English libel law, which is famously plaintiff-friendly, and warned of the dampening effect it is having on scientific discourse before welcoming Singh, who made jokes and thanked the crowd for its support.

Singh has until 28 May 2009 to decide whether to settle the case (for a cool £100,000+, he says), appeal the ruling, or fight the case under the current definition of his article. Lawyers from the Guardian, which was not sued, advised Singh that he was unlikely to win in an English court, but he and his personally retained counsel are still considering whether to appeal Eady’s ruling and how their appeal might fare in a European court, he said.

Asked what impact a ruling against him would have on his science writing career, Singh joked, “I’ll go back to writing cosmology and Fermat’s last theorem. Everyone was very nice about it.”

He added that he would not accept settlement terms that limited his ability to write about chiropractic in the future.
