Petitioner, a resident of New York, brought a libel suit against
respondent magazine publisher (hereafter respondent), an Ohio
corporation, in Federal District Court in New Hampshire, alleging
jurisdiction by reason of diversity of citizenship. Petitioner's
only connection with New Hampshire is the circulation there of a
magazine that she assists in producing. Respondent's contacts with
New Hampshire consist of monthly sales of some 10,000 to 15,000
copies of its nationally published magazine. The District Court
dismissed the suit on the ground that the Due Process Clause of the
Fourteenth Amendment forbade application of New Hampshire's
long-arm statute in order to acquire personal jurisdiction over
respondent. The Court of Appeals affirmed, holding that
petitioner's lack of contact with New Hampshire rendered that
State's interest in redressing the tort of libel to petitioner too
attenuated for an assertion of personal jurisdiction over
respondent, and that, in view of the "single publication rule,"
which would require an award of damages caused in all States, as
well as New Hampshire's unusually long (6-year) limitation period
for libel actions, it would be "unfair" to assert jurisdiction over
respondent.
Held: Respondent's regular circulation of magazines in
the forum State is sufficient to support an assertion of
jurisdiction in a libel action based on the contents of the
magazine. Pp.
465 U. S.
773-781.
(a) New Hampshire jurisdiction over a complaint based on this
circulation of magazines satisfies the Due Process Clause's
requirement that a State's assertion of personal jurisdiction over
a nonresident defendant be predicated on "minimum contacts" between
the defendant and the State. Pp.
465 U. S.
774-775.
(b) In judging minimum contacts, a court properly focuses on
"the relationship among the defendant, the forum, and the
litigation."
Shaffer v. Heitner, 433 U.
S. 186,
433 U. S. 204.
Thus, it is relevant to the jurisdictional inquiry here that
petitioner is seeking to recover damages suffered in all States in
one suit. The contacts between respondent and the forum must be
judged in light of that claim, rather than a claim only for damages
sustained in New Hampshire. P.
465 U. S.
775.
(c) The combination of New Hampshire's interest in redressing
injuries that occur within the State and its interest in
cooperating with other States in applying the "single publication
rule" demonstrates the propriety
Page 465 U. S. 771
of requiring respondent to answer a multistate libel action in
New Hampshire. Pp.
465 U. S.
775-778.
(d) Any potential unfairness in applying New Hampshire's statute
of limitations to all aspects of this nationwide suit has nothing
to do with jurisdiction to adjudicate the claim. And the chance
duration of statutes of limitations of nonforum States has nothing
to do with the contacts among respondent, New Hampshire, and the
suit. Pp.
465 U. S.
778-779.
(e) The fact that petitioner has very limited contacts with New
Hampshire does not defeat jurisdiction, since a plaintiff is not
required to have "minimum contacts" with the forum State before
that State is permitted to assert personal jurisdiction over a
nonresident defendant. A plaintiff's residence in the forum State
is not a separate jurisdictional requirement, and lack of residence
will not defeat jurisdiction established on the basis of the
defendant's contacts. The victim of a libel, like the victim of any
other tort, may choose to bring suit in any forum with which the
defendant has
"certain minimum contacts . . . such that the maintenance of the
suit does not offend 'traditional notions of fair play and
substantial justice.'"

S. 310,
326 U. S. 316.
Pp.
465 U. S.
779-781.
(f) Here, where respondent has continuously and deliberately
exploited the New Hampshire market, it must reasonably anticipate
being haled into court there in a libel action based on the
contents of its magazine. And, since respondent can be charged with
knowledge of the "single publication rule," it must anticipate that
such a suit will seek nationwide damages. There is no unfairness in
calling respondent to answer for the contents of its national
publication wherever a substantial number of copies are regularly
sold and distributed. P.

JUSTICE REHNQUIST delivered the opinion of the Court.
Petitioner Kathy Keeton sued respondent Hustler Magazine, Inc.,
and other defendants in the United States District Court for the
District of New Hampshire, alleging jurisdiction over her libel
complaint by reason of diversity of citizenship. The District Court
dismissed her suit because it believed that the Due Process Clause
of the Fourteenth Amendment to the United States Constitution
forbade the application of New Hampshire's long-arm statute in
order to acquire personal jurisdiction over respondent. The Court
of Appeals for the First Circuit affirmed, 682 F.2d 33 (1982),
summarizing its concerns with the statement that "the New Hampshire
tail is too small to wag so large an out-of-state dog."
Id. at 36. We granted certiorari, 459 U.S. 1169 (1983),
and we now reverse.
Petitioner Keeton is a resident of New York. Her only connection
with New Hampshire is the circulation there of copies of a magazine
that she assists in producing. The magazine bears petitioner's name
in several places crediting her with editorial and other work.
Respondent Hustler Magazine, Inc., is an Ohio corporation, with its
principal place of business in California. Respondent's contacts
with New Hampshire consist of the sale of some 10,000 to 15,000
copies of Hustler Magazine in that State each month.
See
App. 81a-86a. Petitioner claims to have been libeled in five
separate issues of respondent's magazine published between
September, 1975 and May, 1976. [
Footnote 1]
Page 465 U. S. 773
The Court of Appeals, in its opinion affirming the District
Court's dismissal of petitioner's complaint, held that petitioner's
lack of contacts with New Hampshire rendered the State's interest
in redressing the tort of libel to petitioner too attenuated for an
assertion of personal jurisdiction over respondent. The Court of
Appeals observed that the "single publication rule" ordinarily
applicable in multistate libel cases would require it to award
petitioner "damages caused in all states" should she prevail in her
suit, even though the bulk of petitioner's alleged injuries had
been sustained outside New Hampshire. 682 F.2d at 35. [
Footnote 2] The court also stressed New
Hampshire's unusually long (6-year) limitations period for libel
actions. New Hampshire was the only State where petitioner's suit
would not have been time-barred when it was filed. Under these
circumstances, the Court of Appeals concluded that it would be
"unfair" to assert jurisdiction over respondent. New Hampshire has
a minimal interest in applying its unusual statute of limitations
to, and awarding damages for, injuries to a nonresident occurring
outside the State, particularly since petitioner suffered such a
small proportion of her total claimed injury within the State.
Id. at 35-36.
We conclude that the Court of Appeals erred when it affirmed the
dismissal of petitioner's suit for lack of personal jurisdiction.
Respondent's regular circulation of magazines in the forum State is
sufficient to support an assertion of jurisdiction
Page 465 U. S. 774
in a libel action based on the contents of the magazine. This is
so even if New Hampshire courts, and thus the District Court, under
Klaxon Co. v. Stentor Co., 313 U.
S. 487 (1941), would apply the so-called "single
publication rule" to enable petitioner to recover in the New
Hampshire action her damages from "publications" of the alleged
libel throughout the United States. [
Footnote 3]
The District Court found that
"[t]he general course of conduct in circulating magazines
throughout the state was purposefully directed at New Hampshire,
and inevitably affected persons in the state."
App. to Pet. for Cert. 5a. Such regular monthly sales of
thousands of magazines cannot by any stretch of the imagination be
characterized as random, isolated, or fortuitous. It is, therefore,
unquestionable that New Hampshire jurisdiction over a complaint
based on those contacts would ordinarily satisfy the requirement of
the Due Process Clause that a State's assertion of personal
jurisdiction over a nonresident defendant be predicated on "minimum
contacts" between the defendant and the State.
See World-Wide
Volkswagen Corp. v. Woodson, 444 U. S. 286,
444 U. S.
297-298 (1980);
International Shoe Co. v.
Washington, 326 U. S. 310,
326 U. S. 317
(1945). And, as the Court of Appeals acknowledged, New Hampshire
has adopted a "long-arm" statute authorizing service of process on
nonresident corporations whenever permitted by the Due Process
Clause. 682 F.2d at 33. [
Footnote
4] Thus, all the requisites for personal jurisdiction
Page 465 U. S. 775
over Hustler Magazine, Inc., in New Hampshire are present.
We think that the three concerns advanced by the Court of
Appeals, whether considered singly or together, are not
sufficiently weighty to merit a different result. The "single
publication rule," New Hampshire's unusually long statute of
limitations, and plaintiff's lack of contacts with the forum State
do not defeat jurisdiction otherwise proper under both New
Hampshire law and the Due Process Clause.
In judging minimum contacts, a court properly focuses on "the
relationship among the defendant, the forum, and the litigation."
Shaffer v. Heitner, 433 U. S. 186,
433 U. S. 204
(1977).
See also Rush v. Savchuk, 444 U.
S. 320,
444 U. S. 332
(1980). Thus, it is certainly relevant to the jurisdictional
inquiry that petitioner is seeking to recover damages suffered in
all States in this one suit. The contacts between respondent and
the forum must be judged in the light of that claim, rather than a
claim only for damages sustained in New Hampshire. That is, the
contacts between respondent and New Hampshire must be such that it
is "fair" to compel respondent to defend a multistate lawsuit in
New Hampshire seeking nationwide damages for all copies of the five
issues in question, even though only a small portion of those
copies were distributed in New Hampshire.
The Court of Appeals expressed the view that New Hampshire's
"interest" in asserting jurisdiction over plaintiff's multistate
claim was minimal. We agree that the "fairness" of
Page 465 U. S. 776
haling respondent into a New Hampshire court depends to some
extent on whether respondent's activities relating to New Hampshire
are such as to give that State a legitimate interest in holding
respondent answerable on a claim related to those activities.
See World-Wide Volkswagen Corp. v. Woodson, supra, at
444 U. S. 292;
McGee v. International Life Ins. Co., 355 U.
S. 220,
355 U. S. 223
(1957). But insofar as the State's "interest" in adjudicating the
dispute is a part of the Fourteenth Amendment due process equation,
as a surrogate for some of the factors already mentioned,
see
Insurance Corp. of Ireland v. Compagnie des Bauxites de
Guinee, 456 U. S. 694,
456 U. S.
702-703, n. 10 (1982), we think the interest is
sufficient.
The Court of Appeals acknowledged that petitioner was suing, at
least in part, for damages suffered in New Hampshire. 682 F.2d at
34. And it is beyond dispute that New Hampshire has a significant
interest in redressing injuries that actually occur within the
State.
"'A state has an especial interest in exercising judicial
jurisdiction over those who commit torts within its territory. This
is because torts involve wrongful conduct which a state seeks to
deter, and against which it attempts to afford protection, by
providing that a tortfeasor shall be liable for damages which are
the proximate result of his tort.'"
Leeper v. Leeper, 114 N.H. 294, 298, 319 A.2d 626, 629
(1974) (quoting Restatement (Second) of Conflict of Laws § 36,
Comment c (1971)). This interest extends to libel actions brought
by nonresidents. False statements of fact harm both the subject of
the falsehood and the readers of the statement. New Hampshire may
rightly employ its libel laws to discourage the deception of its
citizens. There is "no constitutional value in false statements of
fact."
Gertz v. Robert Welch, Inc., 418 U.
S. 323,
418 U. S. 340
(1974).
New Hampshire may also extend its concern to the injury that
in-state libel causes within New Hampshire to a nonresident.
Page 465 U. S. 777
The tort of libel is generally held to occur wherever the
offending material is circulated. Restatement (Second) of Torts
§ 577A, Comment a (1977). The reputation of the libel victim
may suffer harm even in a State in which he has hitherto been
anonymous. [
Footnote 5] The
communication of the libel may create a negative reputation among
the residents of a jurisdiction where the plaintiff's previous
reputation was, however small, at least unblemished.
New Hampshire has clearly expressed its interest in protecting
such persons from libel, as well as in safeguarding its populace
from falsehoods. Its criminal defamation statute bears no
restriction to libels of which residents are the victim. [
Footnote 6] Moreover, in 1971, New
Hampshire specifically deleted from its long-arm statute the
requirement that a tort be committed "against a resident of New
Hampshire." [
Footnote 7]
New Hampshire also has a substantial interest in cooperating
with other States, through the "single publication rule," to
provide a forum for efficiently litigating all issues and damages
claims arising out of a libel in a unitary proceeding. [
Footnote 8] This rule reduces the
potential serious drain of libel cases on judicial resources. It
also serves to protect defendants from harassment resulting from
multiple suits. Restatement (Second) of Torts § 577A, Comment
f (1977). In sum, the combination of New Hampshire's
interest in redressing injuries that occur within the State and its
interest in cooperating
Page 465 U. S. 778
with other States in the application of the "single publication
rule" demonstrates the propriety of requiring respondent to answer
to a multistate libel action in New Hampshire. [
Footnote 9]
The Court of Appeals also thought that there was an element of
due process "unfairness" arising from the fact that the statutes of
limitations in every jurisdiction except New Hampshire had run on
the plaintiff's claim in this case. [
Footnote 10] Strictly speaking, however, any potential
unfairness in applying New Hampshire's statute of limitations to
all aspects of this nationwide suit has nothing to do with the
jurisdiction of the court to adjudicate the claims. "The issue is
personal jurisdiction, not choice of law."
Hanson v.
Denckla, 357 U. S. 235,
357 U. S. 254
(1958). The question of the applicability of New Hampshire's
statute of limitations to claims for out-of-state damages presents
itself in the course of litigation only after jurisdiction over
respondent is established, and we do not think that such choice of
law concerns should complicate or distort the jurisdictional
inquiry.
Page 465 U. S. 779
The chance duration of statutes of limitations in nonforum
jurisdictions has nothing to do with the contacts among respondent,
New Hampshire, and this multistate libel action. Whether Ohio's
limitations period is six months or six years does not alter the
jurisdictional calculus in New Hampshire. Petitioner's successful
search for a State with a lengthy statute of limitations is no
different from the litigation strategy of countless plaintiffs who
seek a forum with favorable substantive or procedural rules or
sympathetic local populations. Certainly Hustler Magazine, Inc.,
which chose to enter the New Hampshire market, can be charged with
knowledge of its laws, and no doubt would have claimed the benefit
of them if it had a complaint against a subscriber, distributor, or
other commercial partner.
Finally, implicit in the Court of Appeals' analysis of New
Hampshire's interest is an emphasis on the extremely limited
contacts of the plaintiff with New Hampshire. But we have not to
date required a plaintiff to have "minimum contacts" with the forum
State before permitting that State to assert personal jurisdiction
over a nonresident defendant. On the contrary, we have upheld the
assertion of jurisdiction where such contacts were entirely
lacking. In
Perkins v. Benguet Mining Co., 342 U.
S. 437 (1952), none of the parties was a resident of the
forum State; indeed, neither the plaintiff nor the subject matter
of his action had any relation to that State. Jurisdiction was
based solely on the fact that the defendant corporation had been
carrying on in the forum "a continuous and systematic, but limited,
part of its general business."
Id. at
342 U. S. 438.
In the instant case, respondent's activities in the forum may not
be so substantial as to support jurisdiction over a cause of action
unrelated to those activities. [
Footnote 11] But
Page 465 U. S. 780
respondent is carrying on a "part of its general business" in
New Hampshire, and that is sufficient to support jurisdiction when
the cause of action arises out of the very activity being
conducted, in part, in New Hampshire.
The plaintiff's residence is not, of course, completely
irrelevant to the jurisdictional inquiry. As noted, that inquiry
focuses on the relations among the defendant, the forum, and the
litigation. Plaintiff's residence may well play an important role
in determining the propriety of entertaining a suit against the
defendant in the forum. That is, plaintiff's residence in the forum
may, because of defendant's relationship with the plaintiff,
enhance defendant's contacts with the forum. Plaintiff's residence
may be the focus of the activities of the defendant out of which
the suit arises.
See Calder v. Jones, post at
465 U. S.
788-789;
McGee v. International Life Ins. Co.,
355 U. S. 220
(1957). But plaintiff's residence in the forum State is not a
separate requirement, and lack of residence will not defeat
jurisdiction established on the basis of defendant's contacts.
It is undoubtedly true that the bulk of the harm done to
petitioner occurred outside New Hampshire. But that will be true in
almost every libel action brought somewhere other than the
plaintiff's domicile. There is no justification for restricting
libel actions to the plaintiff's home forum. [
Footnote 12] The victim of a libel, like the
victim of any other tort, may choose to bring suit in any forum
with which the defendant has
"certain minimum contacts . . . such that the maintenance of the
suit does not offend 'traditional notions of fair play and
substantial
Page 465 U. S. 781
justice.'
Milliken v. Meyer, 311 U. S.
457,
311 U. S. 463 [(1940)]."
International Shoe Co. v. Washington, 326 U.S. at
326 U. S.
316.
Where, as in this case, respondent Hustler Magazine, Inc., has
continuously and deliberately exploited the New Hampshire market,
it must reasonably anticipate being haled into court there in a
libel action based on the contents of its magazine.
World-Wide
Volkswagen Corp. v. Woodson, 444 U.S. at
444 U. S.
297-298. And, since respondent can be charged with
knowledge of the "single publication rule," it must anticipate that
such a suit will seek nationwide damages. Respondent produces a
national publication aimed at a nationwide audience. There is no
unfairness in calling it to answer for the contents of that
publication wherever a substantial number of copies are regularly
sold and distributed.
The judgment of the Court of Appeals is reversed, [
Footnote 13] and the cause is
remanded for proceedings consistent with this opinion.
It is so ordered.
Page 465 U. S. 782
[
Footnote 1]
Initially, petitioner brought suit for libel and invasion of
privacy in Ohio, where the magazine was published. Her libel claim,
however, was dismissed as barred by the Ohio statute of
limitations, and her invasion of privacy claim was dismissed as
barred by the New York statute of limitations, which the Ohio court
considered to be "migratory." Petitioner then filed the present
action in October, 1980.
[
Footnote 2]
The "single publication rule" has been summarized as
follows:
"As to any single publication, (a) only one action for damages
can be maintained; (b) all damages suffered in all jurisdictions
can be recovered in the one action; and (c) a judgment for or
against the plaintiff upon the merits of any action for damages
bars any other action for damages between the same parties in all
jurisdictions."
Restatement (Second) of Torts § 577A(4) (1977).
[
Footnote 3]
"It is the general rule that each communication of the same
defamatory matter by the same defamer, whether to a new person or
to the same person, is a separate and distinct publication, for
which a separate cause of action arises."
Id. § 577A, Comment a. The "single publication
rule" is an exception to this general rule.
[
Footnote 4]
New Hampshire Rev.Stat.Ann. § 300:14 (1977) provides in
relevant part:
"If a foreign corporation . . . commits a tort in whole or in
part in New Hampshire, such ac[t] shall be deemed to be doing
business in New Hampshire by such foreign corporation and shall be
deemed equivalent to the appointment by such foreign corporation of
the secretary of the state of New Hampshire and his successors to
be its true and lawful attorney upon whom may be served all lawful
process in any actions or proceedings against such foreign
corporation arising from or growing out of such . . . tort."
This statute has been construed in the New Hampshire courts to
extend jurisdiction over nonresident corporations to the fullest
extent permitted under the Federal Constitution.
See, e.g., Roy
v. North American Newspaper Alliance, Inc., 106 N.H. 92, 95,
205 A.2d 844, 846 (1964).
[
Footnote 5]
We do not, therefore, rely for our holding on the fact that
petitioner's name appears in fine print in several places in a
magazine circulating in New Hampshire.
[
Footnote 6]
New Hampshire Rev.Stat.Ann. § 644:11(1) (1974) makes it a
misdemeanor for anyone to
"purposely communicat[e] to
any person, orally or in
writing, any information which he knows to be false and knows will
tend to expose any other living person to public hatred, contempt
or ridicule."
(Emphasis added.)
[
Footnote 7]
See N.H.Rev.Stat.Ann. § 300:14 (1977),
History.
[
Footnote 8]
The great majority of the States now follow the "single
publication rule." Restatement (Second) of Torts § 577A,
Appendix, Reporter's Note (1977).
[
Footnote 9]
Of course, to conclude that petitioner may properly seek
multistate damages in this New Hampshire suit is not to conclude
that such damages should, in fact, be awarded if petitioner makes
out her case for libel. The actual applicability of the "single
publication rule" in the peculiar circumstances of this case is a
matter of substantive law, not personal jurisdiction. We conclude
only that the District Court has jurisdiction to entertain
petitioner's multistate libel suit.
[
Footnote 10]
Under traditional choice of law principles, the law of the forum
State governs on matters of procedure.
See Restatement
(Second) of Conflict of Laws § 122 (1971). In New Hampshire,
statutes of limitations are considered procedural.
Gordon v.
Gordon, 118 N.H. 366, 360, 387 A.2d 339, 342 (1978);
Barrett v. Boston & Maine R. Co., 104 N.H. 70, 178
A.2d 291 (1962). There has been considerable academic criticism of
the rule that permits a forum State to apply its own statute of
limitations regardless of the significance of contacts between the
forum State and the litigation.
See, e.g., R. Weintraub,
Commentary on the Conflict of Laws § 9.2B, p. 517 (2d
ed.1980); Martin, Constitutional Limitations on Choice of Law, 61
Cornell L.Rev. 185, 221 (1976); Comment, The Statute of Limitations
and the Conflict of Laws, 28 Yale L.J. 492, 496-497 (1919). But we
find it unnecessary to express an opinion at this time as to
whether any arguable unfairness rises to the level of a due process
violation.
[
Footnote 11]
The defendant corporation's contacts with the forum State in
Perkins were more substantial than those of respondent
with New Hampshire in this case. In
Perkins, the
corporation's mining operations, located in the Philippine Islands,
were completely halted during the Japanese occupation. The
president, who was also general manager and principal stockholder
of the company, returned to his home in Ohio, where he carried on
"a continuous and systematic supervision of the necessarily limited
wartime activities of the company." 342 U.S. at
342 U. S. 448.
The company's files were kept in Ohio, several directors' meetings
were held there, substantial accounts were maintained in Ohio
banks, and all key business decisions were made in the State.
Ibid. In those circumstances, Ohio was the corporation's
principal, if temporary, place of business, so that Ohio
jurisdiction was proper even over a cause of action unrelated to
the activities in the State.
[
Footnote 12]
As noted in
Calder v. Jones, post at
465 U. S.
790-791, we reject categorically the suggestion that
invisible radiations from the First Amendment may defeat
jurisdiction otherwise proper under the Due Process Clause.
[
Footnote 13]
In addition to Hustler Magazine, Inc., Larry Flynt, the
publisher, editor, and owner of the magazine, and L. F. P., Inc.,
Hustler's holding company, were named as defendants in the District
Court. It does not, of course, follow from the fact that
jurisdiction may be asserted over Hustler Magazine, Inc., that
jurisdiction may also be asserted over either of the other
defendants. In
Calder v. Jones, post at
465 U. S. 790,
we today reject the suggestion that employees who act in their
official capacity are somehow shielded from suit in their
individual capacity. But jurisdiction over an employee does not
automatically follow from jurisdiction over the corporation which
employs him; nor does jurisdiction over a parent corporation
automatically establish jurisdiction over a wholly owned
subsidiary.
Consolidated Textile Co. v. Gregory,
289 U. S. 85,
289 U. S. 88
(1933);
Peterson v. Chicago, R. I. & P. R. Co.,
205 U. S. 364,
205 U. S. 391
(1907). Each defendant's contacts with the forum State must be
assessed individually.
See Rush v. Savchuk, 444 U.
S. 320,
444 U. S. 332
(1980) ("The requirements of
International Shoe . . . must
be met as to each defendant over whom a state court exercises
jurisdiction"). Because the Court of Appeals concluded that
jurisdiction could not be had even against Hustler Magazine, Inc.,
it did not inquire into the propriety of jurisdiction over the
other defendants. Such inquiry is, of course, open upon remand.
JUSTICE BRENNAN, concurring in the judgment.
I agree with the Court that
"[r]espondent's regular circulation of magazines in the forum
State is sufficient to support an assertion of jurisdiction in a
libel action based on the contents of the magazine."
Ante at
465 U. S.
773-774. These contacts between the respondent and the
forum State are sufficiently important and sufficiently related to
the underlying cause of action to foreclose any concern that the
constitutional limits of the Due Process Clause are being violated.
This is so, moreover, irrespective of the State's interest in
enforcing its substantive libel laws or its unique statute of
limitations. Indeed, as we recently explained in
Insurance
Corp. of Ireland v. Compagnie des Bauxites de Guinee,
456 U. S. 694
(1982), these interests of the State should be relevant only to the
extent that they bear upon the liberty interests of the respondent
that are protected by the Fourteenth Amendment.
"The restriction on state sovereign power described in
World-Wide Volkswagen Corp. [v. Woodson, 444 U. S.
286,
444 U. S. 291-292 (1980)]
must be seen as ultimately a function of the individual liberty
interest preserved by the Due Process Clause. That Clause is the
only source of the personal jurisdiction requirement and the Clause
itself makes no mention of federalism concerns."
