(Redirected from Enrolled Bill) The enrolled bill rule is a principle of judicial interpretation of rules of procedure in legislative bodies. Under the doctrine, once a bill passes a legislative body and is signed into law, the courts assume that all rules of procedure in the enactment process were properly followed. That is, f a legislative document is authenticated in regular form by the appropriate officials, the court treats that document as properly adopted.
After passage by both houses, a bill is enrolled and sent to the president for approval. The president may sign it making it law or veto it, perhaps returning it to Congress with his objections. A vetoed bill can still become law if each house of Congress votes to override the veto with a two-thirds majority.
