The proceedings concerned a defamation claim arising from a tweet in which statements made by an unnamed Member of Parliament were described as dangerous, antisemitic, anti-scientific, and conspiratorial in the context of vaccinations. The antisemitism-related core issue was whether the tweet should be understood as attributing antisemitism as a matter of fact to an identifiable individual, or merely as a sharply worded political opinion about the nature of the statements made. The court held, as preliminary issues, that the tweet was predominantly an expression of opinion directed at the content of the statements rather than at the individual as an antisemite, with only the fact that something had been said being classified as a factual assertion.
