In this week’s edition of Insight, we report on the recent Court of Appeal ruling in the case of Chell v Tarmac Cement and Lime Ltd. The Court of Appeal considered an appeal of the decision of His Honour Judge Rawlings sitting at Stoke-on-Trent County Court and appeal of the decision of Mr Justice Martin Spencer. The decision considers whether an employer can be held to be vicariously liable or in breach of duty for injury resulting from horseplay at work.
