In just a few days the House of Representatives is expected to act on two different pieces of legislation: the Senate version of the health-care bill (the one that contains the special deals, "Cadillac" insurance plan taxes, and abortion coverage) and an amendatory bill making changes in the Senate bill. The House will likely adopt a "self-executing" rule that "deems" passage of the amendatory bill as enactment of the Senate bill, without an actual vote on the latter.
This enables the House to enact the Senate bill while appearing only to approve changes to it. The underlying Senate bill would then go to the president for signature, and the amendatory bill would go to the Senate for consideration under reconciliation procedures (meaning no filibuster).
This approach appears unconstitutional. Article I, Section 7 clearly states that bills cannot be presented to the president for signature unless they have been approved by both houses of Congress in the same form. If the House approves the Senate bill in the same legislation by which it approves changes to the Senate bill, it will fail that requirement.
