Civil contempt is only appropriate when the imposed party has the power to comply with the underlying order. Controversial contempt rulings have periodically arisen from cases involving asset protection trusts, where the court has ordered a settlor of an asset protection trust to repatriate assets so that the assets may be made available to a creditor. A court cannot maintain an order of contempt where the imposed party does not have the ability to comply with the underlying order. This claim when made by the imposed party is known as the "impossibility defense".
