April 29 – The Court of King's Bench (England) decides on appeal the legal case Regina v. Hicklin on interpretation of the word "obscene" in the Obscene Publications Act 1857, applying the "Hicklin test": that any part of a publication with a "tendency... to deprave and corrupt those whose minds are open to such immoral influences, and into whose hands a publication of this sort may fall"[5] makes the whole publication obscene, regardless of the author's intentions.[6]
