A vetoed bill returns to the chamber when the legislature reconvenes to reconsider it. Lawmakers can then vote to override the veto; if the required threshold is reached, the bill becomes law despite the executive’s objection. If not, the veto stands.
The return is not simply a second chance to pass the same measure: it is a distinct vote with a higher bar than ordinary passage. Understanding how a vetoed bill returns to the chamber helps clarify who gets the final say when the legislature and the executive disagree.
| Situation | Procedure | Outcome |
|---|---|---|
| Regular veto | Returned with objections to chamber of origin | Chamber may reconsider |
| Originating chamber reaches two-thirds | Bill proceeds to the other chamber | Second override vote required |
| Either chamber falls short | Override attempt fails | Bill does not become law by override |
| Pocket-veto conditions apply | 10 days, Sundays excepted; adjournment prevents return | Bill does not become law |
- 2 chambers The House and Senate must each approve an override.
- 2/3 of members present The required override vote in each chamber under Article I, Section 7.
- 10 days, Sundays excepted The presidential action period relevant to the pocket-veto rule.
How does a vetoed bill return to the chamber?
A federal vetoed bill returns first to the chamber where it originated, along with the president’s objections; that chamber receives the veto message and may reconsider the bill. Article I, Section 7 of the U.S. Constitution sets this return procedure, so the other chamber does not act first.
For a federal bill, Congress can attempt an override only after the returned bill and the president’s objections are before the House or Senate that originated it. The sequence is therefore specific: the originating chamber receives the veto, considers the bill, and only then can Congress pursue an override.
State bills follow state rules
A state bill follows the return and reconsideration procedures in that state’s constitution, not a universal federal rule. Article I, Section 7 governs the federal process; the relevant state constitution determines how a vetoed state bill returns and what happens next.
What can the originating chamber do after the veto?
The first vote is in the chamber of origin.
The House or Senate that first passed a vetoed bill may reconsider it and vote on whether to override the president’s objections. To advance an override, that originating chamber must approve the bill by a two-thirds vote of members present, with a quorum present.
- If two-thirds is reached: The bill may proceed to the other chamber for its own override vote.
- If two-thirds is not reached: The override attempt fails, and the bill does not go to the other chamber for an override vote.
The chamber may stop before a vote.
The House or Senate may also decline to pursue an override, leaving the veto in place. The Constitution’s pocket-veto rule is a separate exception: whether it applies can affect what happens to the bill, rather than the chamber’s ordinary override process.
How does the two-thirds override vote work?
Article I, Section 7 requires two-thirds of the members present in each chamber of Congress to vote for a vetoed bill before it can become law. The threshold is based on members present—not two-thirds of the House’s or Senate’s full membership.
Both chambers must clear the threshold.
The chamber where the bill originated votes first: the House votes first on a House bill, and the Senate votes first on a Senate bill. If that chamber reaches the two-thirds threshold, the bill and the president’s veto message are sent to the other chamber for its vote.
The second chamber must independently secure two-thirds of its members present in favor of the bill. A successful vote in the first chamber is not enough: only when both the House and Senate meet that threshold does the bill become law over the president’s veto.
What happens if either chamber falls short?
If either chamber fails to reach the required two-thirds vote, the veto override fails, and a two-thirds vote in the other chamber cannot make up the shortfall. The bill therefore does not become law through that veto-overturn attempt: both chambers must meet the Constitution’s threshold.
For the override vote, the two-thirds threshold is calculated from members present, not from the chamber’s full membership. Attendance can therefore change the number of affirmative votes needed; the constitutional test is two-thirds of those present in each chamber.
What happens next
A failed override does not automatically send the vetoed bill back for another vote. Any reconsideration or further legislative action depends on the applicable chamber rules and the circumstances; neither chamber’s successful vote alone completes an override when the other falls short.
When does the ordinary return-and-vote process not apply?
Pocket veto: 10 days, Sundays excluded.
The ordinary return-and-vote process does not apply when a pocket veto takes effect: the president neither signs a bill nor returns it, and Congress adjourns in a way that prevents its return before the Constitution’s 10-day period, excluding Sundays, expires. Whether an adjournment has that effect depends on its timing and on whether the bill can be returned.
- Regular veto: The president returns the bill, with objections, to the chamber where it originated. Congress may then consider the veto under the applicable federal process.
- Pocket veto: The president does not return the bill through that ordinary procedure; when the conditions are met, the bill does not become law.
State veto rules require a separate check against the relevant state constitution. A state’s procedures may differ from the federal return process, and readers should not assume that the federal two-thirds threshold applies to a state legislature. The key distinction is therefore not simply whether the president or governor acted within 10 days: for a pocket veto, the effect of adjournment matters too.
What are the practical limits of an override?
A federal veto override is limited by a two-thirds vote in each chamber, making it harder than passing a bill under ordinary voting rules. The House of Representatives and the Senate must each reach that threshold independently; a strong vote in the chamber where the bill began cannot substitute for the second chamber’s approval.
Count members present, not the full chamber
Article I, Section 7 sets the federal threshold at two-thirds of the members present, provided a quorum is present. That is not automatically two-thirds of the full House or the full Senate: the required number depends on how many members are present when that chamber votes. Treating the threshold as a fixed fraction of total membership can therefore misstate the votes needed.
State veto overrides require a separate check. The federal rule in Article I, Section 7 does not by itself establish the procedure for a state legislature; the relevant state constitution and legislative rules determine the threshold and process. Before applying the federal two-thirds standard to a state bill, verify those state-specific requirements.
