Simon Singh at the Guardian‘s “Comment is Free” site explains just how much the chilling effect of English libel law can obstruct free speech:
. . . it is important to remember that for every case of a scientist or journal who dares to face the ordeal of a libel trial, there are dozens of (or probably hundreds of) others who immediately apologise and retract after a libel threat, or who self-censor in order avoid any risk of libel, which is the so-called chilling effect of libel.
For example, I gave an interview to an Australian medical correspondent at the Melbourne Age about the lack of evidence surrounding homeopathy, but he was unable to quote me in detail because his in-house lawyer was frightened of being sued for libel in London. The only reason this came to light was because the journalist in question wrote a blog describing how tough it was to be a health journalist in Australia when the vulture of English libel law was always circling above.
More worryingly, I recently received an email from an American researcher (whose name I cannot mention) who had worked with a librarian (whose name I cannot mention) to write a paper on the subject of impact factors, the scoring system often used by librarians and others to assess the quality of a research journal. The anonymous researchers cited one journal (whose name I cannot mention) which may be using certain techniques to boost its own impact factor. Impact factors are an important issue, so the paper was sent to a respected British journal (which I shall not name in order to avoid embarrassment) with an international readership. The journal replied: “We regret that we are unable to publish after all because unfortunately it has potential legal implications under UK libel law.”
The anonymous researchers then sent the paper to an American journal (which I shall not name), which also had an international readership and which did agree to publish the paper. Initially, there seemed to be no problem, because the in-house lawyer agreed that the paper did not breach US libel law. However, the lawyer went on to demand that edits were necessary or there would be a serious risk of being sued in London according to English libel law.
The British government is to introduce a new bill to (one hopes) address some of these concerns soon. Let’s hope that they’re paying attention.
