damming warrant
n.— «Napolitano said a practice known as “damming warrants” has resulted in the state seizing $15 million in the last year from 12,400 wire transfers. The name comes from the procedure which allows state prosecutors to get a court order to “dam” up wire transfers unless and until the person to whom the money was sent can show the cash is for a legal purpose.» —“Human smugglers’ $15M ‘dammed up'” by Howard Fischer in Phoeniz Arizona Daily Star (Tucson) Mar. 21, 2006.
