His Majesty’s Attorney General v Elavi Dowie [2022] EWCA Civ 1574

The Court of Appeal ruled that Mr Dowie could have no possible complaint about his conviction and eight-month sentence but adjusted the costs order on account of Mr Dowie’s means. The Court of Appeal also helpfully noted that there was “considerable force” in the Attorney General’s position that (contrary to the decision in the court below) it was not an element of the mens rea of the category of contempt of court involved that the defendant needed to have an intention to interfere with the course of justice.
