CERTIORARI TO THE COURT OF APPEALS
OF THE DISTRICT OF COLUMBIA.
Syllabus
1. A citizen of the United States residing in a foreign country
continues to owe allegiance to the United States and is bound by
its laws made applicable to his situation. P.
284 U. S.
436.
2. The power to require the return of absent citizens in the
public interest is inherent in sovereignty, and what in England was
the sovereign prerogative in this respect pertains, under our
constitutional system, to the national authority, exercisable by
Congress, to prescribe the duties of the citizens of the United
States. P.
284 U.S.
437.
3. One of the duties of such absent citizens to the United
States is that of attending its courts to give testimony when
properly summoned, and Congress may provide for the performance of
this duty and prescribe penalties for disobedience. P.
284 U. S.
438.
4. Questions of authority in such cases are not questions of
international law, but of municipal law. P.
284 U.S. 437.
5. The Act of July 3, 1926, provides that, when the testimony of
a citizen of the United States residing in a foreign country is
needed by the Government in a criminal case, the court in which the
case is pending may issue a subpoena to be served upon him
personally by an American consul with a tender of money to cover
his necessary expenses of travel to and from, and attendance upon,
the court; that, if he refuse or neglect to appear as directed by
the subpoena, the same court, upon proof of service and default,
may issue its order directing him to appear before it at a
designated time to show cause why he should not be adjudged guilty
of contempt
Page 284 U. S. 422
and be punished; that this order may direct that property of the
witness in the United States be seized and held to satisfy any
judgment that may be rendered in the contempt proceeding; that,
after such seizure, the order to show cause and for sequestration
shall be served on the witness personally by such consul and shall
be published in some newspaper of general circulation in the
district where the court sits, and that, on the return day of the
order, or later, proof shall be taken, and if the charge of
recusancy shall be sustained, the court shall adjudge the witness
guilty of contempt and impose upon him a fine not exceeding
$100,000, which, with the costs, may be satisfied by sale of the
property levied upon, to be conducted upon notice and in the manner
provided for sales upon execution. In contempt proceedings for
failure to obey subpoenas,
held:
(1) The absent witness is bound with notice of the statute. P.
284 U. S.
438.
(2) The method provided by the Act for acquiring judicial
jurisdiction to render a personal judgment includes due notice and
opportunity to be heard, and satisfies the due process clause of
the Fifth Amendment. Pp.
284 U. S.
438-439.
(3) Service of the subpoena in a foreign country invades no
right of the foreign government, and the citizen has no standing to
invoke such supposed right. P.
284 U. S.
439.
(4) The function of a consul in serving the subpoena and the
order to show cause is merely that of an agent of the government
for conveying actual notice to one of its citizens; it need not be
sanctioned by a treaty. Pp.
284 U. S.
439-440.
(5) In criminal contempt proceedings, due process does not
require that the respondent be present at the hearing and
adjudication if he was duly notified and had adequate opportunity
to appear and be heard. P.
284 U. S. 440.
(6) The contempt proceeding being valid, the provisional remedy
of seizing and applying property to secure payment of the penalty
is also constitutional. P.
284 U. S. 441.
(7) The fact that enforcement of the penalty may depend on
seizure of property does not imply unconstitutional discrimination
between those contumacious absentee witnesses who have property in
this country and those who have not.
Id.
(8) A provisional or final levy on property, as provided in the
statute, to satisfy liability of the owner is not an unreasonable
search and seizure.
Id.
Page 284 U. S. 423
(9) The question whether the statute grants the right to
subpoena foreign residents in criminal cases to the government
only, and thereby violates the provision of the Sixth Amendment
guaranteeing accused persons compulsory process for witnesses, will
not be considered at the instance of a recalcitrant witness. P.
284 U. S.
442.
(10) Where the subpoena served was issued at the request of the
government upon a statement as to the materiality and importance of
the expected testimony sufficient to give the court jurisdiction to
issue it, it binds the witness unless set aside upon proper
petition, and the question whether the showing was otherwise
sufficient cannot be raised in defense against proceedings to
punish his disobedience as contempt.
Id.
(11) It is not necessary that the subpoena issued under the
statute show on its face that it was so issued.
Id.
(12) Where a witness has been served with subpoena under the
statute, and has defaulted, service of an order directing him to
show cause, at a time and place stated, why he should not be
adjudged guilty of contempt, and providing for seizure of his
property to be held to satisfy any judgment that may be rendered
against him in the proceeding, affords notice sufficient to inform
him of the character of the charge and of the hearing at which he
will have opportunity to present his defense. P.
284 U. S.
443.
(13) Where two subpoenas are issued for appearances at different
times, a seizure of property in connection with the first is not
vacated by the seizure of the same property in connection with the
second.
Id.
(14) A witness subpoenaed to attend on a day named, and not to
depart the court without leave of the court or the district
attorney, cannot excuse his refusal to come upon the ground that
the trial did not begin on the day specified in the writ, but on a
later day to which the case was continued.
Id.
60 App.D.C. 141, 49 F.2d 523, affirmed.
Certiorari to review decrees sustaining fines imposed on the
petitioner Blackmer as punishment for contemptuous disobedience of
two subpoenas in a criminal case. The judgments provided that the
fines be satisfied out of property seized after the subpoenas were
served.
Page 284 U. S. 433
MR. CHIEF JUSTICE HUGHES delivered the opinion of the Court.
The petitioner, Harry M. Blackmer, a citizen of the United
States resident in Paris, France, was adjudged guilty of contempt
of the Supreme Court of the District of Columbia for failure to
respond to subpoenas served upon him in France and requiring him to
appear as a witness on behalf of the United States at a criminal
trial in that court. Two subpoenas were issued, for appearances at
different times, and there was a separate proceeding with respect
to each. The two cases were heard together, and a fine of $30,000
with costs was imposed in each case, to be satisfied out of the
property of the petitioner which had been seizer by order of the
court. The decrees were affirmed by the Court of Appeals of the
District, 49 F.2d 523, and this Court granted writs of
certiorari.
The subpoenas were issued and served, and the proceedings to
punish for contempt were taken, under the provisions of the Act of
July 3, 1926, c. 762, 44 Stat. 835, U.S.C. Tit. 28,
§§ 711-718. [
Footnote 1]
The statute provided that,
Page 284 U. S. 434
whenever the attendance at the trial of a criminal action of a
witness abroad, who is "a citizen of the United States or domiciled
therein," is desired by the Attorney General or any assistant or
district attorney acting under him, the judge of the court in which
the action is pending may order a subpoena to issue, to be
addressed to a consul of the United States and to be served by him
personally
Page 284 U. S. 435
upon the witness with a tender of traveling expenses.
§§ 2, 3. Upon proof of such service and of
the failure of the witness to appear, the court may make an order
requiring the witness to show cause why he should not be punished
for contempt, and, upon the issue of such an order, the court may
direct that property belonging to the witness and within the United
States may be seized and held to satisfy any judgment which may be
rendered
Page 284 U. S. 436
against him in the proceeding. §§ 4, 5.
Provision is made for personal service of the order upon the
witness and also for its publication in a newspaper of general
circulation in the district where the court is sitting.
§ 6. If, upon the hearing, the charge is sustained, the
court may adjudge the witness guilty of contempt and impose upon
him a fine not exceeding $100,000, to be satisfied by a sale of the
property seized. § 7. This statute and the proceedings
against the petitioner are assailed as being repugnant to the
Constitution of the United States.
First. The principal objections to the statute are that
it violates the due process clause of the Fifth Amendment. These
contentions are: (1) that the "Congress has no power to authorize
United States consuls to serve process except as permitted by
treaty;" (2) that the Act does not provide "a valid method of
acquiring judicial jurisdiction to render personal judgment against
defendant and judgment against his property;" (3) that the Act
"does not require actual or any other notice to defendant of the
offense or of the government's claim against his property;" (4)
that the provisions "for hearing and judgment in the entire absence
of the accused and without his consent" are invalid, and (5) that
the Act is "arbitrary, capricious and unreasonable."
While it appears that the petitioner removed his residence to
France in the year 1924, it is undisputed that he was, and
continued to be, a citizen of the United States. He continued to
owe allegiance to the United States. By virtue of the obligations
of citizenship, the United States retained its authority over him,
and he was bound by its laws made applicable to him in a foreign
country. Thus, although resident abroad, the petitioner remained
subject to the taxing power of the United States.
Cook v.
Tait, 265 U. S. 47,
265 U. S. 54-56.
For disobedience to its laws through conduct abroad, he was subject
to punishment in the courts of the United States.
United
States v. Bowman,
Page 284 U. S. 437
260 U. S. 94,
260 U. S. 102.
With respect to such an exercise of authority, there is no question
of international law, [
Footnote 2] but solely of
the purport of the municipal law which establishes the duties of
the citizen in relation to his own government. [
Footnote 3] While the legislation of the Congress, unless
the contrary intent appears, is construed to apply only within the
territorial jurisdiction of the United States, the question of its
application, so far as citizens of the United States in foreign
countries are concerned, is one of construction, not of legislative
power.

213 U. S. 357;
United States v. Bowman, supra; Robertson v. Labor Board,
268 U. S. 619,
268 U. S. 622.
Nor can it be doubted that the United States possesses the power
inherent in sovereignty to require the return to this country of a
citizen, resident elsewhere, whenever the public interest requires
it, and to penalize him in case of refusal.
Compare Bartue and
the Duchess of Suffolk's Case, 2 Dyer's Rep. 176b, 73 Eng.Rep.
388;
Knowles v. Luce, Moore 109, 72 Eng.Rep. 473.
[
Footnote 4] What in England was the prerogative
of the sovereign
Page 284 U. S. 438
in this respect pertains under our constitutional system to the
national authority which may be exercised by the Congress by virtue
of the legislative power to prescribe the duties of the citizens of
the United States. It is also beyond controversy that one of the
duties which the citizen owes to his government is to support the
administration of justice by attending its courts and giving his
testimony whenever he is properly summoned.
Blair v. United
States, 250 U. S. 273,
250 U. S. 281.
And the Congress may provide for the performance of this duty and
prescribe penalties for disobedience.
In the present instance, the question concerns only the method
of enforcing the obligation. [
Footnote 5] The
jurisdiction of the United States over its absent citizen, so far
as the binding effect of its legislation is concerned, is a
jurisdiction
in personam, as he is personally bound to
take notice of the laws that are applicable to him, and to obey
them.
United States v. Bowman, supra. But, for the
exercise of judicial jurisdiction
in personam, there must
be due process, which requires appropriate notice of the judicial
action and an opportunity to be heard. For this notice and
opportunity, the statute provides. The authority to require the
absent citizen to return and testify necessarily implies the
authority to give him notice of the requirement. As his attendance
is needed in court, it is appropriate that the Congress should
authorize the court to direct the notice to be given, and that it
should be in the customary form of a subpoena. Obviously, the
requirement would be nugatory if provision could not be made for
its communication to the witness in the foreign country.
Page 284 U. S. 439
The efficacy of an attempt to provide constructive service in
this country would rest upon the presumption that the notice would
be given in a manner calculated to reach the witness abroad.
McDonald v. Mabee, 243 U. S. 90,
243 U. S. 92.
The question of the validity of the provision for actual service of
the subpoena in a foreign country is one that arises solely between
the government of the United States and the citizen. The mere
giving of such a notice to the citizen in the foreign country of
the requirement of his government that he shall return is in no
sense an invasion of any right of the foreign government, and the
citizen has no standing to invoke any such supposed right. While
consular privileges in foreign countries are the appropriate
subjects of treaties, [
Footnote 6] it does not
follow that every act of a consul, as,
e.g., in
communicating with citizens of his own country, must be predicated
upon a specific provision of a treaty. The intercourse of friendly
nations, permitting travel and residence of the citizens of each in
the territory of the other, presupposes and facilitates such
communications. In selecting the consul for the service of the
subpoena, the Congress merely prescribed a method deemed to assure
the desired result, but in no sense essential. The consul was not
directed to perform any function involving consular privileges or
depending upon any treaty relating to them, but simply to act as
any designated person might act for the government in conveying to
the citizen the actual notice of the requirement of his attendance.
The point raised by the petitioner with respect to the provision
for the service of the subpoena abroad is without merit.
As the Congress could define the obligation, it could prescribe
a penalty to enforce it. And as the default lay in disobedience to
an authorized direction of the court, it
Page 284 U. S. 440
constituted a contempt of court, and the Congress could provide
for procedure appropriate in contempt cases. The provision of the
statute for punishment for contempt is applicable only "upon
proof's being made of the service and default." § 4.
That proof affords a proper basis for the proceeding, and provision
is made for personal service upon the witness of the order to show
cause why he should not be adjudged guilty. For the same reasons as
those which sustain the service of the subpoena abroad, it was
competent to provide for the service of the order in like manner.
It is only after a hearing pursuant to the order to show cause, and
upon proof sustaining the charge, that the court can impose the
penalty. The petitioner urges that the statute does not require
notice of the offense, but the order to show cause is to be issued
after the witness has failed to obey the subpoena demanding his
attendance and the order is to be made by the court before which he
was required to appear. This is sufficient to apprise the witness
of the nature of the proceeding, and he has full opportunity to be
heard. The further contention is made that, as the offense is a
criminal one, it is a violation of due process to hold the hearing,
and to proceed to judgment, in the absence of the defendant. The
argument misconstrues the nature of the proceeding.
"While contempt may be an offense against the law and subject to
appropriate punishment, certain it is that, since the foundation of
our government proceedings to punish such offenses have been
regarded as
sui generis, and not 'criminal prosecutions'
within the Sixth Amendment or common understanding."

95,
264 U. S.
104-105.

194 U. S. 327,

266 U. S. 65-66;
Ex parte Grossman, 267 U. S. 87,
267 U. S.
117-118. The requirement of due process in such a case
is satisfied by suitable notice and adequate opportunity to appear
and to be heard.
Cf. Cooke v. United States, 267 U.
S. 517,
267 U. S.
537.
Page 284 U. S. 441
The authorization of the seizure of the property belonging to
the defaulting witness and within the United States, upon the issue
of the order to show cause why he should not be punished for
contempt (§ 5 of the Act) affords a provisional remedy,
the propriety of which rests upon the validity of the contempt
proceeding. As the witness is liable to punishment by fine if, upon
the hearing, he is found guilty of contempt, no reason appears why
his property may not be seized to provide security for the payment
of the penalty. The proceeding conforms to familiar practice where
absence or other circumstance makes a provisional remedy
appropriate.
See Cooper v.
Reynolds, 10 Wall. 308,
77 U. S. 318.
The order that is to be served upon the witness contains the
direction for the seizure. The property is to be held pending the
hearing, and is to be applied to the satisfaction of the fine if
imposed and unless it is paid. Given the obligation of the witness
to respond to the subpoena, the showing of his default after
service, and the validity of the provision for a fine in case
default is not excused, there is no basis for objection to the
seizure upon constitutional grounds. The argument that the statute
creates an unreasonable classification is untenable. The
disobedience of the defaulting witness to a lawful requirement of
the court, and not the fact that he owns property, is the ground of
his liability. He is not the subject of unconstitutional
discrimination simply because he has property which may be
appropriated to the satisfaction of a lawful claim.
Second. What has already been said also disposes of the
contention that the statute provides for an unreasonable search and
seizure in violation of the Fourth Amendment. It authorizes a levy
upon property of the witness at any place within the United States
in the manner provided by law or rule of court for levy or seizure
under execution. A levy in such a manner, either provisionally
Page 284 U. S. 442
or finally, to satisfy the liability of the owner, is not within
the constitutional prohibition.
The petitioner raises the further and distinct point that the
statute limits the availability of the subpoena to the government,
and that, "by excluding defendants in criminal prosecutions" from
the right to such a subpoena, it violates the provision of the
Sixth Amendment that the accused shall have "compulsory process for
obtaining witnesses in his favor." We need not consider whether the
statute requires the construction for which the petitioner
contends, as, in any event, the petitioner, a recalcitrant witness,
is not entitled to raise the question.
Nelson v. United
States, 201 U. S. 92,
201 U. S. 115;
Southern Railway Co. v. King, 217 U.
S. 524,
217 U. S. 534;
Jeffrey Manufacturing Co. v. Blagg, 235 U.
S. 571,
235 U. S. 576;
Blair v. United States, supra, at p.
250 U. S.
282.
Third. The statute being valid, the question remains as
to the procedure in its application against the petitioner. He
insists that the showing for the issue of the subpoenas requiring
him to attend was inadequate. But the "proper showing" required was
for the purpose of satisfying the court that the subpoenas should
issue. The petitions in the instant cases were presented to the
judge of the court by the official representatives of the
government, and their statement as to the materiality and
importance of the testimony expected from the witness was
unquestionably sufficient to give the court jurisdiction to issue
the subpoenas, and, unless they were vacated upon proper
application, the petitioner was bound to obey. Nor was it necessary
that the subpoenas should "identify" themselves with the statute
under which they were issued. The petitioner, as a citizen of the
United States, was chargeable with knowledge of the law under which
his attendance as a witness could be required. It was sufficient
that the subpoenas required his attendance to testify on behalf of
the United States at the time and place stated.
Page 284 U. S. 443
Equally unavailing is the objection that, after the petitioner
had refused to appear in response to the subpoenas, the orders to
show cause why he should not be punished for contempt did not
specify the offense. As the statute prescribed, he had been served
with the subpoenas and had defaulted, and he had also been served
with the order which directed him to show cause why he should not
be adjudged guilty of contempt and provided for the seizure of his
property to be held to satisfy any judgment that might be rendered
against him in the proceeding. The notice which he thus received
was sufficient to inform him of the character of the charge against
him and of the hearing at which he would have opportunity to
present his defense. The petitioner also insists that the seizure
which was made in case No. 200 was abandoned by virtue of the
seizure of the same property under the order issued in No. 201. But
the second levy was not antagonistic to the first. The proceedings
were consistent.
In No. 201, the contention is made that the petitioner was
subpoenaed to attend on April 2, 1928, and that the case in which
his testimony was desired was not tried until April 9, 1928. There
is no suggestion that the petitioner appeared on April 2, 1928, in
compliance with the subpoena, and the record shows that the case in
which he was subpoenaed was continued by the court until the later
date. The subpoena contained the usual provision that the witness
was "not to depart the court without leave of the court or district
attorney."
Cf. R.S. § 877, U.S.C. Tit. 28,
§ 655. It was the duty of the petitioner to respond to
the subpoena and to remain in attendance until excused by the court
or by the government's representatives.
Decrees affirmed.
MR. JUSTICE ROBERTS took no part in the consideration and
decision of this case.
[
Footnote 1]
The Act is as follows:
"
Be it enacted by the Senate and House of Representatives of
the United States of America in Congress assembled, That
whenever letters rogatory shall issue out of any court of the
United States, either with or without interrogatories addressed to
any court of any foreign country, to take the testimony of any
witness, being a citizen of the United States or domiciled therein,
and such witness, having been personally notified by it according
to the practice of such court, to appear and testify pursuant to
such letters rogatory and such witness shall neglect to appear, or
having appeared shall decline, refuse or neglect to answer to any
question which may be propounded to him by or under the authority
of such court, to which he would be required to make answer were he
being examined before the court issuing such letters, the court out
of which said letters issued may upon proper showing order that a
subpoena issue addressed to any consul of the United States within
any country in which such witness may be, commanding such witness
to appear before the said court at a time and place therein
designated."
"Sec. 2. Whenever the attendance at the trial of any criminal
action of a witness, being a citizen of the United States or
domiciled therein, who is beyond the jurisdiction of the United
States, is desired by the Attorney General or any assistant or
district attorney acting under him, its judge of the court before
which such action is pending, or who is to sit in the trial of the
same, may, upon proper showing, order that a subpoena issue,
addressed to any consul of the United States within any country in
which such witness may be, commanding such witness to appear before
the said court at a time and place therein designated."
"Sec. 3. It shall be the duty of any consul of the United States
within any country is which such witness may be at the request of
the clerk of the court issuing any subpoena under this Act or at
the request of the officer causing such subpoena to be issued, to
serve the same personally upon such witness and also to serve any
orders to show cause, rules, judgments, or decrees when requested
by the court or United States marshal, and to make a return thereof
to the court out of which the same issued, first tendering to the
witness the amount of his necessary expenses in traveling to and
from the place at which the court sits and his attendance thereon,
which amount shall be determined by the judge on issuing the order
for the subpoena and supplied to the consul making the
service."
"Sec. 4. If the witness so served shall neglect or refuse to
appear as in such subpoena directed, the court out of which it was
issued shall, upon proof being made of the service and default,
issue an order directing the witness to appear before the court at
a time in such order designated to show cause why he should not be
adjudged guilty of contempt and be punished accordingly."
"Sec. 5. Upon issuing such order, the court may, upon the giving
of security for any damages which the recusing witness may have
suffered, should the charge be dismissed (except that no security
shall be required of the United States), direct as a part of such
order that the property of the recusing witness at any place within
the United States, or so much thereof in value as the court may
direct shall be levied upon and seized by the marshal of said court
in the manner provided by law or the rule of the court for a levy
or seizure under execution, to be held to satisfy any judgment that
may be rendered against such witness in the proceeding so
instituted."
"Sec. 6. The marshal, having made such levy, shall thereupon
forward to the consul of any country where the recusing witness may
be a copy of the order to show cause why such witness should not be
adjudged guilty of contempt with the request that said consul make
service of the same personally upon the recusing witness, and shall
cause to be published such order to show cause and for the
sequestration of the property of such witness, in some newspaper of
general circulation in the district within which the court issuing
such order sits, once each week for six consecutive weeks."
"Sec. 7. On the return day of such order or any later day to
which the hearing may by the court be continued, proof shall be
taken, and if the charge of recusancy against the witness shall be
sustained, the court shall adjudge him guilty of contempt and,
notwithstanding any limitation upon the power of the court
generally to punish for contempt, impose upon him a fine not
exceeding $100,000 and direct that the amount thereof, with the
costs of the proceeding, be satisfied, unless paid, by a sale of
the property of the witness so seized or levied upon, such sale to
be conducted upon the notice required and in the manner provided
for sales upon execution."
"Sec. 8. Any judgment rendered pursuant to this Act upon service
by publication only may be opened for answer within the time and in
the manner provided in § 57 of the Judicial Code."
