The U.K. Charity Commission has ruled that the Tate broke the law by buying art produced by serving artist-trustees, including a £600,000 work by Chris Ofili. According to a report in the Guardian today, "by law, trustees cannot receive monetary benefit from their charity without express permission, usually from the commission. The Tate failed to seek permission, not only in the case of the Ofili work, ... but in 17 previous purchases of work by artist-trustees going back 50 years."
