When a President executes a pocket veto, the President does nothing. No signature, no veto message, no bill returned to Congress. The bill simply sits on the President’s desk while the ten-day signing window runs out and Congress is adjourned, and at the end of that period the bill dies without ever becoming law. The whole mechanism is built out of inaction and timing.
The Mechanics of Doing Nothing
Three things have to line up. First, Congress passes a bill and delivers it to the White House. Second, the President neither signs it nor sends it back with objections. Third, Congress adjourns before the ten-day period (Sundays excluded) runs out, so there is no chamber available to receive a returned bill.1Constitution Annotated. Overview of Presidential Approval or Veto of Bills When those conditions come together, the bill fails. That failure is the pocket veto.
Timing is everything. If the President sits on a bill for ten days while Congress is still in session, the bill automatically becomes law without a signature. Inaction only kills a bill when it is paired with a congressional adjournment that blocks the return.1Constitution Annotated. Overview of Presidential Approval or Veto of Bills So the President’s “action” is really a decision to hold the bill and let the calendar do the work.
The Optional Memorandum of Disapproval
Presidents are not always literally silent. Many issue what is called a memorandum of disapproval, a written statement explaining why they chose not to sign. It is not constitutionally required and it does not function as a formal veto message. It has no procedural consequence. Its only role is to put the President’s policy objections on the public record. A regular veto message goes back to Congress and triggers a possible override vote; a memorandum of disapproval does neither.
Why Silence Is Enough: The Constitutional Basis
Article I, Section 7 sets three possible outcomes once a bill reaches the President. The President can sign it into law. The President can return it to the originating chamber with written objections, giving Congress a shot at overriding the veto with a two-thirds vote in both houses. Or, if the President neither signs nor returns the bill within ten days and Congress has adjourned during that window, the bill does not become law.2Constitution Annotated. Constitution Annotated – Article I Section 7 Clause 2 The Constitution never uses the phrase “pocket veto.” The term is informal shorthand for that third outcome: Congress left, the President could not return the bill even if the President had wanted to, and so the bill dies.3Constitution Annotated.

Why This Nothing Is Different From a Regular Veto
A regular veto is an active rejection. The President sends the bill back to its chamber of origin with written objections, and Congress can try to override with a two-thirds vote in both the House and the Senate.2Constitution Annotated. Constitution Annotated – Article I Section 7 Clause 2 If the override succeeds, the bill becomes law over the President’s objections.
A pocket veto removes that possibility. Because the bill is never returned, there is nothing for either chamber to vote on. Congress cannot override a pocket veto. If lawmakers still want the legislation, they have to start over: reintroduce the bill in a future session, pass it through both chambers again, and send it back to the President.3Constitution Annotated. ArtI.S7.C2.2 Veto Power That is the strategic weight behind doing nothing. A President facing a Congress with the votes to override a regular veto can kill a bill outright with a pocket veto, so long as the timing cooperates.
Which Adjournments Make Inaction Fatal
Not every congressional break turns silence into a pocket veto. The question is whether the adjournment actually prevents the President from delivering the bill back to the originating chamber.
The clearest case is a final adjournment at the end of a session. In The Pocket Veto Case (1929), the Supreme Court held that the qualifying adjournment is not limited to the end of an entire Congress. Any adjournment that prevents the President from returning the bill counts. The test is functional: can the originating chamber receive the bill, enter the objections on its journal, and reconsider it? If the chamber is dispersed and not sitting as an organized body, the President cannot return the bill, and the pocket veto stands.4Justia. The Pocket Veto Case
Shorter breaks are a different matter. In Wright v. United States (1938), the Supreme Court held that a temporary adjournment of a single chamber does not prevent the return of a bill; the President can deliver a vetoed bill to an appropriate officer of that chamber. The D.C. Circuit went further in Kennedy v. Sampson (1974), holding that no adjournment within a session prevents return so long as Congress has arranged for someone to receive presidential messages. In that case, the President attempted a pocket veto during a Christmas recess, and the court ruled the bill had actually become law because arrangements had been made and the recess did not truly block a return.5CaseMine. Kennedy v. Sampson, 511 F.2d 430
Some scenarios remain unsettled. The Supreme Court has never ruled on whether a pocket veto works when only one chamber has adjourned for an extended break between sessions while the other remains, or on pocket vetoes during longer within-session breaks. The Department of Justice has taken the position that pocket vetoes remain valid during intersession adjournments regardless of whether Congress appoints agents to receive messages, but lower courts have challenged that view.6U.S. Department of Justice.

Pro Forma Sessions Shrink the Window
Congress now uses pro forma sessions to stay technically in session even when most members are gone. A single lawmaker gavels in, often for under a minute, and gavels out. No legislative business happens. The practice was designed mainly to block recess appointments, but it also narrows the pocket veto window.
In NLRB v. Noel Canning (2014), the Supreme Court held that the Senate’s own determination of when it is in session deserves significant weight, though that deference is not absolute. The Court found the Senate retained the power to conduct business under its own rules during the pro forma sessions at issue and was therefore in session.7Justia U.S. Supreme Court Center. NLRB v. Canning That case dealt with recess appointments rather than pocket vetoes, but the logic carries over. If Congress is considered in session during pro forma periods, the President likely cannot pocket veto a bill during that time. A bill held unsigned for ten days across pro forma sessions would become law automatically instead of dying from inaction.
So the President’s role in a pocket veto stays what it has always been: hold the bill, sign nothing, send nothing, and let the ten days expire while Congress is away. The bill’s fate is settled by what the President does not do.
