The Ruling focuses on arrangements that are cancelled by or on behalf of a recipient or intended recipient and a fee is charged (including the forfeiture of all or part of the consideration for the intended supply). A supplier may also cancel an arrangement. However, in the latter case a cancellation fee is usually not charged. Therefore, the Ruling does not deal with cancellations made by a supplier except in relation to a ticketed arrangement for the supply of performances, events or similar arrangements.
