Mr. Justice Sanford
delivered the opinion of the Court..
This case presents the question whether, under the second clause in Section 7 of Article I of the Constitution of the .United States, a bill which is* passed by both Houses' of Congress during the first regular sessio'n of a particular Congress and presented to the President less than ten days (Sundays excepted) before the adjournment of that session, but is neithér signed by the President nor returned by him to the House in which it originated, becomes a law in like manner as if he had signed it.
At the first session of the 69th Congress Senate Bill No. 3185, entitled “An Act authorizing certain Indian tribes and bands, or any of them, residing in the State of Washington, to present their claims to the Court of Claims,” having been passed by both Houses .of Congress and duly authenticated, was presented to the President on June 24, 1926. On July 3 the first session of the 69th Congress was adjourned, under a house concurrent resolution.
The Congress was not again in session until the commencement of the second session on the first Monday in December.
And neither House of Congress was in session on' July 6— the tenth day after the bill had been presented to the President (Sundays excepted).
The President neither signed the bill nor returned it to the Senate. And it was not published as a law.
Taking the position that the bill had become a law without the signature of the President, the. Okanogan and other Indian tribes residing in the State of Washington in' March, 1927, filed a petition in the Court of Claims setting up certain claims in accordance with the terms of the bill. The United States demurred to the petition. The court sustained the demurrer and dismissed the petition, on the ground that under the provisions of the Constitution the bill had hot become a law. 66 C. Cls. 26.
In view of the public importance of the question presented we granted the petitioners a writ of certiorari. 278 U. S. 597. And for like reason, at the request of the Committee on the Judiciary of the House of Representatives, we granted Mr. Sumners, a member of that Committee, leave to appear as
amicus curiae.
He has aided üsby a "comprehensive and forcible presentation of arguments against the conclusion of the court below.
The clause of the Constitution here in question reads as follows: “Every Bill which shall have passed the House of Representatives and the Senate, shall, before it become a Law, be presented to the President of the United States; If he approve he shall sign it, but if not he shall return it, with his Objections to that House-in which it shall have originated, who shall enter the Objections at large on their Journal, and proceed to reconsider it.' If after such Reconsideration two thirds of that House shall agree to pass the Bill, it shall be sent, together with the Objections, to the other House, by which it shall likewise be reconsidered; and if approved by two thirds of that House, it shall become a Law. ...
If any Bill shall not be returned by the 'President within ten Days (Sundays excepted) after it shall have been presented to him, the Same shall be a Law, in like Manner as if he had signed it,
unless the Congress by their Adjournmeñt prevent its Return, in which Case it shall not be a
Law.”
The specific question here presented is whether, within the meaning of the last sentence — which wé have italicized — Congress by the adjournment on July 3 prevented the President from returning the bill within ten days, Sundays excepted, after it had been presented to him. If the adjournment did not prevent him from returning the bill within the prescribed time, it became a law without his signature; but, if the adjournment prevented him from so doing, it did not become a law. This is unquestioned.
In support of the position that the adjournment did not prevent the President from returning the bill within the prescribed time, counsel for the petitioners and the
amicus curiae
urge that the only
“
adjournment ” which prevents' the President from returning a bill within the prescribed time is the final adjournment of the Congress, terminating its legislative existence and making it impossible for the President to return the bill for its reconsideration ;- and that an adjournment of the first session of the Congress-does not prevent the President from returning the bill within the prescribed time since the legislative existence of the Congress is not terminated, and he may within that.time return the bill to the House in which it originated, although not then in session, by delivering it, with his objections, to the Secretary, Clerk, or other appropriate agent of that House, to be held by such agent
and presented to the House when the Congress resumes its sitting at the next session — thereby enabling the Congress to proceed with the reconsideration of the bill a^ a part of the unfinished legislative business carried over from the first session. And it is also said, by counsel for the petitioners, that the “ ten days ” allowed for the return of the bill, may be construed as meaning “ legislative days,” that is, days on which the Congress is in legislative session, and not calendar days, thereby enabling the President to return the bill within ten days, Sundays excepted, exclusive of all days on which the Congress was not in legislative session, even although, by reason of an adjournment, this period does not expire until after the Congress has resumed its legislative sittings at the second session.
In support of the position that Congress by the adjournment on July 3 prevented the President from returning the bill within the prescribed time, the Attorney General maintains that the word “ adjournment ” includes an interim adjournment as well as the final adjournment at the end of a Congress; that the words “ ten days ” mean calendar days, and not legislative days; that the President cannot return a bill with his objections to' the House in which it originated except by returning it to the House while in session; that if, by reason of an adjournment taken by Congress within the prescribed time, the House in which the bill originated be not in session on the last of such days and the bill cannot be thus returned, the President is thereby prevented from returning the bill within the prescribed time; and that this view is supported by the practical construction given to the constitutional provision by the President through a long course of years, in which Congress has acquiesced.
No light is thrown on the meaning of the constitutional provision in the proceedings and debates of the Constitutional
Convention; and there has been no decision of
this Court dealing directly with its meaning and effect in respect to the precise question here involved. And while we have been cited to various decisions of state courts construing similar provisions in state constitutions, an examination of them discloses such a conflict of opinion— due in some part to differences in phraseology or their application to the procedure of the state legislatures— that, viewed as a whole, they furnish no substantial aid in the determination of the question here presented and a detailed consideration of them here would not be helpful. For that reason we shall cite in thiá opinion only some that seem most apposite and persuasive in their reasoning.
1. It is earnestly insisted by counsel for the petitioners and by the
amicus curiae,
as the underlying basis of their contentions, that since clause 2 gives the President merely a qualified negative over legislation and requires him, if he disapproves a bill, to return it with his objections to the House in which it originated so that Congress -may have an opportunity to reconsider it in the light of such objections and pass it by a two-thirds vote of each House, the provision as to the return of a bill within a specified time is to be construed in,a manner that will give effect to the reciprocal rights and duties of the President and of Congress and not enable him to defeat a bill of which he disapproves by a silent and “ absolute veto,” that is, a so-called “ pocket veto,” which neither discloses his objections nor gives Congress an opportunity to pass the bill over them. This argument involves a misconception of the reciprocal rights and duties of the President and of Congress and of the situation resulting from an adjournment of Congress which prevents the President from returning a bill with his objections within the specified time. This is illustrated in the use of the term “ pocket veto,” which does not acurately describe the situation, and is misleading in its implications in that it suggests that the
failure of the bill in such case is necessarily due to the disapproval of the President and the intentional withholding of the bill from reconsideration. The Constitution in giving the President a qualified negative over legislation — commonly called a veto — entrusts him with, an authority and imposes upon him an obligation that are of the highest importance, in the execution of which it is made his duty not only to sign bills that he approves in order that they may become law, but to return bills that he disapproves, with his objections, in order that they may be reconsidered by Congress. The faithfúl and effective exercise of this momentous duty necessarily requires time in which the President may carefully examine and consider a bill and determine, after due deliberation, whether he should approve or disapprove it, and if he disapproves it, formulate his objections for the consideration of Congress. To that end a specified time is given, after the bill has been presented to him, in which he may examine its provisions and either approve it or return it, not approved, for reconsideration. See
La Abra Silver Mining Co.
v.
United States,
175 U. S. 423, 455.
The power thus con
ferred upon the President cannot be narrowed or cut down by Congress, nor the time within which it is to be exercised lessened, directly or indirectly.
And it is just as essential a part of the constitutional provisions, guarding against ill-considered and unwise legislation, that the President, on his part, should have the full time allowed him for determining whether he should approve.or disapprove a bill, and if disapproved, for adequately formulate ing the objections that should be considered by Congress, as it is that Congress, on its part, should have an opportunity to re-pass the bill over his objections.
It will frequently happen — especially when many bills are presented to the President near the close of a session, some of which are complicated or deal with questions of great moment — that when Congress adjourns before the time allowed for his consideration and action has expired, he will not have been able to determine whether some of them should be approved or disapproved, or, if disapproved, to formulate adequately the objections which should receive the consideration of Congress. And it is plain that when the adjournment of Congress prevents the return of a bill within the allotted time, the failure of the bill to become a law cannot properly be ascribed to the disapproval of the President — who presumably would have returned it before the adjournment if there had been sufficient time in which to complete his consideration and
take such action — but is attributable solely to the action of Congress in adjourning before the time allowed the President for returning the bill had expired. Thus, in
La Abra Silver Mining Co.
v.
United States, supra,
454, this Court said that “ if by its action, after the presentation of a bill to the President during the time given him by the Constitution for an examination of its provisions and for approving it by his signature, Congress puts it out of his power to return it, not approved, within that time to the House in which it originated, then the bill falls, and does not become a law.”
2. There is plainly no warrant for adopting the suggestion of counsel for the petitioners — which is not urged by the
amicus curiae
— that the phrase
“
within ten Days (Sundays excepted),” may be construed as meaning, not calendar days, but “ legislative days,” that is, days during which Congress is in legislative session — thereby excluding all calendar days which are not also legislative days from the computation of the period allowed the President for returning a bill. The words used in the Constitution are to be taken in their natural and obvious sense,
Martin
v.
Hunter’s Lessee,
1 Wheat. 304, 326, and are to be given the meaning they have in common use unless there are very strong reasons to the contrary.
Tennessee
v.
Whitworth,
117 U. S. 139, 147. The word
“
days,” when not qualified, means in ordinary and common usage calendar days. This is obviously the' .meaning in which it is used in the constitutional provision, and is emphasized by the fact that
“
Sundays ” are excepted.- There is nothing whatever to justify changing this meaning by inserting the word legislative
”
as a qualifying adjective. And no President or Congress has ever suggested that the Pres
ident has ten “ legislative days ” in which to consider and return a bill, or proceeded upon that theory.
3. Nor can we agree with the argument that the word “ adjournment ” as used in the constitutional provision refers only to the final adjournment of the Congress. The word “ adjournment
”
is not qualified by the word “final; ” and there is nothing in the context which warrants the insertion of such a limitation. On the contrary, the fact that the word “ adjournment
”
as used in the Constitution is not limited to a final adjournment, is shown by the first clause in section 5 of Article I, which provides that a smaller number than a majority of each House may “ adjourn ” from day to day, and'by the fourth clause of the same Article, which provides that neither House, during'’the session of Congress, shall, without the consent of the other, “ adjourn ” for more than three days. And the Standing Rules of the Senate refer specifically to motions to “ adjourn to a day certain
”
(No. XXII); and the Rules of the House of Representatives, to an “adjournment ” at the end of one session (No. XXVI).
4. We think that under the constitutional provision the determinative question in reference to an
“
adjournment is not whether it is a final adjournment of Congress or an interim adjournment, such as an adjournment of the first session, but whether it is one that “ prevents ” the President from returning the bill to the House in which it originated within, the time allowed. It is clear, and, as
we understand, is not questioned, that since the President may return a bill at any time within the allotted period, he is prevented from returning it, within the meaning of the constitutional provision, if by reason of the adjournment it is impossible for him to return it to the House in which it originated on the last day of that period. It is also conceded, as we understand, that the President is necessarily prevented from returning a bill by a final adjournment of the Congress, since such adjournment terminates the legislative existence of the Congress and makes* it impossible to return the bill to either House. And the crucial question here presented is whether an interim adjournment of Congress at the end of the first session, as the result of which, although the legislative existence of the House in which the bill originated has not been terminated, it is not in session on the last day of the period allowed the President for returning the bill, likewise prevents him from returning it to such House. This brings us to the specific question whether, in order to return the bill to the House in which it originated, within the meaning o£ the constitutional provision, it is necessary, as the Attorney. General insists,' that it be returned to the House itself while it is in session, or whether, as urged by counsel for the petitioners and by the
amicus curiae,
it may be returned to the House, although not in session, by delivering it to an officer or agent of the House, to be held by him and delivered to the House when it resumes its sittings at the next session.
Clause 2 specifically provides that if the President doés not approve a bill
“
he shall return it, with his Objections to that House in which it shall have originated, who shall enter the Objections at large on their Journal, and proceed to reconsider it.” That is, it provides in the same phrase and with no change in definition, that the “ House ” to which the bill is to be returned is that which
is to enter the objections on its journal and proceed to reconsider the bill.
From a consideration of the entire clause we think that the “ House ” to which the bill is to be returned, is the House in session. In
Missouri Pac. Ry. Co.
v.
Kansas,
248 U. S. 276, 280, 281, 283, this Court, in holding that the provision in this clause requiring a vote of two-thirds of each House to pass a bill over the President’s objections, means two-thirds of a quorum of each House and not two-thirds of all its members, said
arguendo,
that “the context leaves no doubt that the provision was dealing with the two houses as organized and entitled to exert legislative power,” that is, the legislative bodies “ organized, conformably to law for the purpose of enacting legislation and, after stating that the identity between this provision and that in Article V of the Constitution, giving “ two-thirds of both Houses ” the power to submit amendments, makes the practice as to one applicable to the other, quoted with approval the “ settled rule . . . clearly and aptly stated ” by the Speaker, Mr. Reed, in the House, on the passage of the amendment to the Constitution providing for the election of Senators by the vote of the people, as follows: “What constitutes a House? A quorum of the membership, a majority, one-half and one more. That is all that is necessary to constitute a House to do all the business that comes before the House. Among the business that comes before the House is the reconsideration of a bill which has been vetoed by the President; another is a proposed amendment to the Constitution; and the practice is uniform in both cases that if a quorum of the House is present the House is constituted and two-thirds of those voting are sufficient in order to accomplish the object. . .
Since the bill is to be returned to the same “ House,” and none' other, that is to enter the President’s objections
on its journal
and proceeded to reconsider the bill — there being only one and the same reference to such House— it follows, in our opinion, that under "the constitutional mandate it is to be returned to the “ House ” when sitting in an organized capacity for the transaction of business, and having authority to receive the return, enter the President’s objections on its journal, and proceed to reconsider the bill; and that no return can be made to the House when it is not in session as a collective body and its members are dispersed. This is the view expressed in 1 Curtis’ Constitutional History of the United States, 486, n. 1, in which it is said: “ This expression, a ‘house,’ or ‘ each house,’ is several times employed in the Constitution with reference to the faculties and powers of the two chambers respectively, and it always* means, when so used, the constitutional quorum, assembled for the transaction of business, and capable of transacting business. This same expression was employed by the committee when-they provided for the mode in which a bill, once rejected by the president, should be again brought before the legislative bodies. They directed it to be returned ‘
to that House in which it shall have originated
’ — that is to say, to a constitutional quorum, a majority of which passed it in the first instance. ...”
This accords with the long established practice of both Houses of Congress to receive messages from the . President while they are in session. See Senate Standing Rule XXVIII, cl. 1; House Rule XL; 5 Hind’s Precedents of the House of Representatives, ch. CXXXVIII, especially sec. .6591, p. 812.
We find no substantial basis for the suggestion that although the House in which the bill originated is not in session the bill may nevertheless be returned, con
sistently with the constitutional mandate, by delivering it, with the President’s objections, to an officer or agent of the House, for subsequent delivery to the House when it resumes its sittings at the next session, with the same force and effect as if the bill had. been returned to the House on the day when it was delivered to
sndk
officer or agent. Aside from the fact that Congress has never enacted any statute authorizing any officer or agent of either House to receive for it bills returned by the President during its adjournment, and that there is no rule to that effect in either House, the delivery of the bill to such officer or agent, even if authorized by Congress itself, would not comply with the constitutional mandate. The House, not having been in session when the bill was delivered to the officer or agent, could neither have received the bill and objections at that time, nor have entered the objections upon its journal, nor have ..proceeded to reconsider the bill, as the Constitution requires; and there is nothing i'n the Constitution which authorizes either House to make a
nunc pro tunc
record of the return of a bill as of a date on which it had not, in fact, been returned. Manifestly it was not intended that, instead of returning the bill to the House itself, as required by the constitutional provision, the President should be authorized to deliver it, during an adjournment of the House, to some individual officer or agent not authorized to make any legislative record of its delivery, who should hold it in his own hands for days, weeks or perhaps months, — not only leaving open possible questions as to the date on which it had been delivered to him, or whether it-' had in fact been delivered to him at all, but-keeping the bill in the meantime in a state of suspended 'animation until the House resumes its sittings, with no certain knowledge on the part of-the public as to whether it had or had not been seasonably delivered, and necessarily causing delay in its. reconsideration which the Constitution’ evidently intended to avoid. In short, it was plainly the.object
of the constitutional provision that there should be a timely return of the bill, which should not only be a matter of official record definitely shown by the journal of the House itself, giving public, certain and prompt knowledge as to the status of the bill, but should enable Congress to proceed immediately with its reconsideration; and that the return of the bill should be an actual and public return to the House itself, and not a fictitious return by a delivery of the bill to some individual which could be given a retroactive effect at a later date when the time for the return of the bill to the House had expired.
Thus Attorney General Devens, in a memorandum to President Hayes, said: “All these provision's indicate that in order to enable the President to return a bill the Houses should be in session; and if by their own act they see fit to adjourn and deprive him of the opportunity to return the bill, with his objection, and are not present themselves to receive and record these objections and to act thereon, the bill can not become a law unless ten days shall have expired during which the President will have had the opportunity thus to return it. There is no suggestion that he may return it to the Speaker, or Clerk, or any officer of the House; but the return must be made to the House as an organized body.”
It is significant that only one attempt has ever been made in Congress to authorize the President to return a bill when the House in which it originated was not in session; and that this failed. In 1868 a bill was reported by the Senate Judiciary' Committee for regulating the return of bills by the President.
While this specifically declared that the constitutional provision allowed the President ten calendar days (Sundays excepted) in which to return' a bill not approved by him, and that the return
of a bill would be prevented by "the final adjournment of a session ” of Congress, although not by an adjournment' to a particular day, it provided that if at any time within such ten days the President désired to'return the bill to the house in which it originated when such house was not sitting, he might return it to the office of the Secretary of the Senate or Clerk of the House of Representatives, as the case might be, who should endorse thereon the day on which such return was made, and make an entry of the fact of such return in his journal of the proceedings, and that such return should be deemed a return of the bill to all intents and purposes. In the debate in the Senate, strong opposition was expressed to this feature of the bill on constitutional grounds;
and
although it passed the Senate by a majority vote, it was never reported from the Judiciary Committee of the House of Representatives, to which it was referred, and thus failed to pass the Congress., It does not appear that this suggestion has ever been renewed in Congress.
5. The views which we have expressed as to the construction and effect of the constitutional' provision here in question are confirmed by the practical construction that has been given to.it by the Presidents through a long
course of years, in which Congress has acquiesced. Long settled and established practice is a consideration of great, weight in a proper interpretation of constitutional provisions of this character. Compare
Missouri Pac. Ry. Co.
v.
Kansas, supra,
284;
Myers
v.
United States,
272 U. S. 52, 119, 136; and
State
v.
South Norwalk,
77 Conn. 257, 264, in which the court said that a practice of at least twenty, years duration “ on the part of the executive department, acquiesced in by the legislative department, while not absolutely binding on the judicial department, is entitled to great regard in determining the true construction of a constitutional provision the phraseology of which is in any respect of doubtful meaning.”
A memorandum prepared in the office of the Attorney General showing the results of an exhaustive research of governmental archives for the purpose of disclosing the practical construction placed upon the constitutional provision here involved in reference to so-called “ pocket vetoes,” was transmitted by the President to Congress in December 1928.
This memorandum — -the accuracy of which is not questioned — cites more than 400 bills and resolutions which were passed by Congress and submitted to the President less than’ten days before affinal or interim adjournment of Congress, which were not signed by the President nor returned with his disapproval. Of these, 119 were instances in which the adjournment was that at the end of a session of Congress, as distinguished from the final adjournment of the Congress. None of these bills or resolutions was placed upon the statute books or treated as having become a law; nor does it appear that there was any attempt to enforce them in the courts until the present suit was brought. Of these instances 11 oc
curred before the end of President Lincoln’s administration, and the remainder from the end of that administration to the present time. They arose under the administration of all the Presidents except ten. These 119 bills and resolutions are thus classified in the brief of the
amicus curiae:
Private relief bills, 36; pension bills, 19; obsolete purposes, 10; relating to District of Columbia, 9; relating to personal status, 8; right of way over Indian and government land, 8; river and harbor bills, 7; disposition of war stores and government property, 5; reduction of national debts, 3; and general legislation, .14. It does not appear that in any of these instances either House of Congress in any official manner questioned the validity and effect of the President’s action in not returning the bill after the adjournment of the session, or proceeded on the theory that it had become a law, although neither signed nor. returned, - tmtil the action was taken in the House Committee of the Whole in 1927 to which we have referred.
And in some instances new bills were introduced in place of those that had not been returned. Without analyzing these 119 instances in detail, we think they show that for a long series of years, commencing with President Madison’s administration and continuing until the action of the House Committee of the Whole in 1927, all the Presidents who have had occasion to deal with this question have adopted and carried into effect the construction of the constitutional provision that they were prevented from returning the bill to the House in which it originated by the adjournment of the session of Congress; and that this construction has been acquiesced in by both Houses of Congress until 1927.
6. For these reasons we conclude that the adjournment of the first session of the 69th Congress on July 3, 1926, prevented the President, within , the meaning of the con
stitutional provision, from returning Senate Bill
No.
3185 within ten days, Sundays excepted, after it had been presented to him, and that it did not become a law.
