Defamation - Wilson v Mendelsohn concerns a dispute over offensive and defamatory posts on social media that arose from a personal dispute and were later disseminated publicly. The parties involved were engaged in a public debate on antisemitism, Israel and Zionism, to which the online posts referred. The High Court dealt exclusively with the civil law question of whether the publications were unlawful and did not make any decision on the substantive assessment of antisemitism.
