The Robert Rauschenberg Foundation is challenging a Florida judge’s $24.6 million award to three friends of the artist for overseeing his estate.

Christopher Rauschenberg, the foundation’s chairman, said he and other directors felt a responsibility to file the notice to appeal, on Wednesday, August 13. “Our job is to advance the best interests of the foundation and its charitable mission,” he said in a statement.

A year ago, Christopher Rauschenberg was quoted in the New York Times saying, “If a judge says $60 million is fair, we’ll put it behind us and continue with the charitable stuff.”
