This one made me wonder: "Moreover, English libel law favors the claimant — the person who says he or she has been defamed — in several ways. [...] in English libel cases, the burden of proof is effectively on the defendant. In other words, the defamatory statement is presumed to be false unless the defendant can prove it is true."

Is there really a law system where it's the other way around? This would be slanderer's paradise. One could write libelous articles as long as one made them hard to disprove.
