delivered the opinion of the Court.
This case arose from an animal welfare dispute. At issue is the fate of certain monkeys used for medical experiments funded by the Federal Government. The case comes before us, however, on a narrow jurisdictional question: whether a suit filed in state court challenging the treatment of these monkeys was properly removed to the federal court by respondent National Institutes of Health (NIH), one of the defendants. We hold that removal was improper and that the case should be remanded to state court.
1 — I
Petitioners, who are organizations and individuals seeking the humane treatment of animals, filed this suit in Louisiana civil district court; the monkeys are housed at a primate research center in that State. Three defendants were named *75 and are respondents here. Respondent Institutes for Behavior Resources (IBR) is a private entity that owns the monkeys. 1 Respondent NIH now maintains custody of the monkeys, with IBR’s consent. Respondent Administrators of the Tulane Educational Fund (Tulane) is the governing body for the primate research center that, in 1986, entered into an agreement with NIH to care for the monkeys. The suit sought to enjoin further experimentation on the monkeys and to obtain custody over them. Petitioners based their claim for this relief upon Louisiana law, including provisions that (1) impose criminal sanctions for cruelty to animals, La. Rev. Stat. Ann. §14:102.1 (1986 and Supp. 1991); (2) permit officers of humane societies to remove, to a “stable,” animals being subjected to cruelty or that are “bruised, wounded, crippled, abrased, sick, or diseased,” La. Rev. Stat. Ann. §3:2431 (1987); (3) authorize tort damages for “[ejvery act whatever of man that causes damage to another,” La. Civ. Code Ann., Art. 2315 (1979 and Supp. 1991); and (4) direct courts to “proceed according to equity” in situations not covered by “legislation or custom,” La. Civ. Code Ann., Art. 4 (Supp. 1991). See App. to Pet. for Cert. A-35 to A-37.
Shortly after the suit was filed, NIH removed the case to federal court pursuant to 28 U. S. C. § 1442(a)(1), which authorizes removal of state suits by certain federal defendants. The federal District Court then granted a temporary re *76 straining order barring NIH from carrying out its announced plan to euthanize three of the remaining monkeys and, in the process, to complete some of the medical research by performing surgical procedures. The court extended this order beyond its 10-day limit, see Fed. Rule Civ. Proc. 65(b), and NIH accordingly appealed the court's action under 28 U. S. C. § 1292(a)(1), which permits appellate review of preliminary injunctions.
On appeal, NIH argued, inter alia, that petitioners were not entitled to the injunction because they lacked standing to seek protection of the monkeys. Petitioners, in turn, argued that the District Court had no juris~1iction over the case because 28 U. S. C. § 1442(a)(1) permits only federal officials-not federal agencies such as NIH-to remove cases in which they are named as defendants. The Court of Appeals for the Fifth Circuit agreed with NIH that petitioners could not satisfy the requirements under Article III of the United States Constitution for standing. It also held that federal agencies have the power to remove cases under § 1442(a)(1). Accordingly, the Court of Appeals vacated the injunction and dismissed the case. See
II
We confront at the outset an objection raised by NIH to our jurisdiction over the removal question. NIH argues that, because the Court of Appeals found that petitioners lack Article III standing to seek protection of the monkeys, petitioners also lack standing even to contest the removal of *77 their suit. We beli,eve NIH misconceives both standing doctrine and the scope of the lower court’s standing ruling.
Standing does not refer simply to a party’s capacity to appear in court. Rather, standing is gauged by the specific common-law, statutory or constitutional claims that a party presents. “Typically, . . . the standing inquiry requires careful judicial examination of a complaint’s allegations to ascertain whether the particular plaintiff is entitled to an adjudication
of the particular claims asserted.
”
Allen
v.
Wright,
It is well established that a party may challenge a violation of federal statute in federal court if it has suffered “injury that fairly can be traced to the challenged action of the defendant,”
Simon
v.
Eastern Kentucky Welfare Rights Org.,
Nothing in the Court of Appeals’ decision undermines this conclusion. The court below found that petitioners did not have standing to protest “disruption of their personal relationships with the monkeys,”
*79 III

Section 1442(a)(1) permits a defendant in a civil suit filed in state court to remove the action to a federal district court if the defendant is “[a]ny officer of the United States or any agency thereof, or person acting under him, [in a suit challenging] any act under color of such office . . . 28 U. S. C. § 1442(a)(1).

The question before us is whether this provision permits agencies to remove. “‘[T]he starting point in every case involving construction of a statute is the language itself.’”
Watt
v.
Alaska,
Several features of § 1442(a)(1)’s grammar and language support this reading. The first is the statute’s punctuation. Cf.
United States
v.
Ron Pair Enterprises, Inc.,
Secondly, the language that follows “[a]ny officer of the United States or any agency thereof” confirms our reading of that clause. The subsequent grant of removal authority to any “person acting under him” makes little sense if the immediately preceding words — which ought to contain the antecedent for “him” — refer to an agency rather than to an individual. Finally, the phrase in § 1442(a)(1) that limits exercise of the removal power to suits in which the federal defendant is challenged for “any act under color of such office” reads very awkwardly if the prior clauses refer not only to persons but to agencies. An agency would not normally be described as exercising authority “under color” of an “office.” In sum, IBR’s interpretation of § 1442(a)(1) simply does not accord with the statute’s language and structure.
IBR tries to rescue its argument by invoking the well-established principle that each word in a statute should be given effect. See 2A N. Singer, Sutherland on Statutory *81 Construction §46.06 (C. Sands 4th rev. ed. 1984). IBR contends that any officer of an agency is also an officer of the United States and therefore that the reference to “agency thereof” in § 1442(a)(1) is redundant unless it signifies the agency itself. IBR notes, in support of this contention, that when Congress enacted § 1442(a)(1) it also defined “agency” as “any department, independent establishment, commission, administration, authority, board or bureau of the United States or any corporation in which the United States has a proprietary interest.” 28 U. S. C. §451. Since the words “of the United States” modify all of the entities listed in § 451, IBR concludes that an officer of an agency is necessarily an “officer of the United States.” Brief for Respondent IBR 16-17.
We find this argument unpersuasive. IBR’s broad definition of “officer of the United States” may well be favored today. Cf.
Buckley
v.
Valeo,
B
Respondent NIH finds an alternative basis for agency removal power in the subsequent clause of § 1442(a)(1) that grants removal authority to any “person acting under him.” In NIH’s view, since the word “him” refers to an officer of the United States, an agency would be a “person acting under him” because each agency is administered or directed by such an officer. This is a rather tortured reading of the language. We doubt that, if Congress intended to give removal authority to agencies, it would have expressed this intent so obliquely, referring to agencies merely as entities “acting under” the agency heads.
NIH faces an additional hurdle, moreover, in arguing that the word “person” in the phrase “person under him” should refer to an agency. As we have often noted, “in common usage, the term ‘person’ does not include the sovereign, [and]
*83
statutes employing the [word] are ordinarily construed to exclude it.”
Will
v.
Michigan Dept. of State Police,
Nevertheless, “there is no hard and fast rule of exclusion” of the sovereign,
United States
v.
Cooper Corp.,
During the 15 years prior to enactment of § 1442(a)(1) in 1948, Congress created several independent agencies that it authorized to “sue and be sued” in their own names in both state and federal courts. In NIH’s view, these selective waivers of sovereign immunity gave Congress a reason to extend the removal authority to include agencies. Thus, NIH argues, the word “person” in the removal statute should be read as referring to such agencies. Although none of these early “sue and be sued” statutes involved major departments of the Federal Government,
6
we agree that those laws
could have
prompted Congress to change its removal policy. However, we find no persuasive evidence that Congress actually made such a change when it revised the removal statute in
*84
1948. NIH concedes that each of the nine preceding versions of the removal statute, extending as far back as 1815, limited the removal authority to some subset of federal
officers.
See Brief for Respondent NIH 21-23, and n. 18; see also
Willingham
v.
Morgan,
C
NIH argues, finally, that even if a literal reading of § 1442(a)(1) would exclude agencies from the removal power, we should reject that construction because it produces absurd results. See,
e. g., Public Citizen
v.
Department of Justice,
We think Congress could rationally have made such a distinction. As we have already noted, for more than 100 years prior to 1948, Congress expressly limited whatever removal power it conferred upon federal defendants to individual officers. NIH does not suggest that any of these earlier statutes produced absurd results; indeed, it acknowledges that, “[i]n drafting these removal provisions, Congress referred to federal officers because they, and not federal agencies, were the ones being sued in state courts.” Brief for Respondent NIH 23. The reason agencies were not being sued, of course, was that Congress had not consented to such suits and the agencies were therefore shielded by sovereign immunity. See,
e. g., Larson
v.
Domestic & Foreign Commerce Corp.,
By contrast, the question of the immunity of federal officers who were named as defendants was much more complicated. Such immunity hinged on “the crucial question . . . whether the relief sought in a suit nominally addressed to the officer [was] relief against the sovereign.”
Larson
v.
Domestic & Foreign Commerce Corp.,
The situation in the present case is no different from what would have obtained under the pre-1948 statutes. NIH’s defense in this case is precisely that it is not amenable to suit in state court by reason of sovereign immunity.
7
As noted, there is nothing irrational in Congress’ determination that adjudication of that defense may be safely entrusted to a state judge. The only question remaining, then, is whether the distinction Congress initially drew between agencies and officers continued to be rational in 1948, when Congress revised the removal statute. Although by then Congress had waived the immunity to suit of several independent agencies,
8
see
supra,
at 83, and n. 6, we find no fatal inconsis
*87
tency in Congress’ determination that these few agencies’ other federal defenses (i. e., those aside from immunity) could be adjudicated in state courts. A crucial reason for treating federal officers differently remained: because of the manipulable complexities involved in determining their immunity, federal officers needed the protection of a federal forum. See
Willingham
v.
Morgan, supra,
at 407 (“[0]ne of the most important reasons for removal is to have the validity of the defense of official immunity tried in a federal court”); see also
Arizona
v.
Manypenny,
IV
Having concluded that NIH lacked authority to remove petitioners’ suit to federal court, we must determine whether the case should be remanded to state court. Section 1447(c) of Title 28 provides that, “[i]f at any time before final judgment it appears that the district court lacks subject matter jurisdiction [over a case removed from state court], the case shall be remanded.” Since the district court had no original jurisdiction over this case, see n. 4,
supra,
a finding that removal was improper deprives that court of subject matter jurisdiction and obliges a remand under the terms of § 1447(c). See, e. g.,
Brewer
v.
Department of Housing and Urban Development,
Notwithstanding the clear requirements of § 1447(c), NIH asks us to affirm the Court of Appeals’ dismissal of this suit on the ground that a remand of petitioners’ claims to Louisiana court would be futile. NIH reasons that it is an indispensable party to the suit and thus that petitioners will be required, on remand, to retain NIH as a defendant (in which case the suit will have to be dismissed, since NIH cannot be *88 sued in state court) or to substitute an NIH official as defendant (who presumably will then remove the case pursuant to § 1442(a)(1)). Alternatively, NIH argues that even if the suit can proceed without an NIH defendant, Tulane will be able to remove the case under § 1442(a)(1) since, in caring for the monkeys, Tulane is a “person acting under” an NIH officer. See Tr. of Oral Arg. 30, 33. Obviously, if any of these events is certain to occur, a remand would be futile.
NIH finds authority for a futility exception to the rule of remand in
Maine Assn. of Interdependent Neighborhoods
v.
Commissioner, Maine Dept. of Human Services,
The purported grounds for the futility
of
a remand in
M. A. I. N.
were (1) the plaintiff’s lack of standing, (2) the state Commissioner’s declared intent to remove the case (following remand) in his capacity as a “person acting under” the Secretary of Health and Human Services (HHS), and (3) the ability of the Secretary of HHS (a third-party defendant) also to effect removal, as an “officer of the United States.” The First Circuit concluded that none of these anticipated barriers to suit in state court was sufficiently certain to render a remand futile. To begin with, plaintiff’s lack of Article III
*89
standing would not necessarily defeat its standing in state court. Secondly, plaintiff’s suit challenged an action by the state Commissioner that was not necessarily an “act under color of [federal] office,” a prerequisite to the exercise of removal power under § 1442(a)(1). Finally, the First Circuit doubted whether the Secretary of HHS would be an indispensable party in state court.
Similar uncertainties in the case before us preclude a finding that a remand would be futile. Whether NIH is correct in arguing that either it or one of its officers will be deemed an indispensable party in state court turns on a question of Louisiana law, and we decline to speculate on the proper result. Similarly, whether Tulane will be able to remove the remanded case requires a determination whether it is a “person acting under” the Director of NIH within the meaning of § 1442(a)(1). This mixed question of law and fact should not be resolved in the first instance by this Court, least of all without an appropriate record. We also take note, as did the First Circuit, of “the literal words of § 1447(c), which, on their face, give ... no discretion to dismiss rather than remand an action.” Id., at 1054. The statute declares that, where subject matter jurisdiction is lacking, the removed case “shall be remanded.” 28 U. S. C. § 1447(c) (emphasis added). We therefore reverse the decision of the Court of Appeals and remand the case to the District Court with instructions that the case be remanded to the Civil District Court for the Parish of Orleans, Louisiana.
It is so ordered.
Notes
IBR conducted the original research on these monkeys, testing their ability to regain use of their limbs after certain nerves had been severed. This research was carried out with NIH funds at IBR’s facilities in Silver Spring, Maryland. In 1981, however, Maryland police seized the monkeys and arrested the scientist supervising the research on charges of cruelty to animals in violation of state law. While those charges were pending, a Maryland court gave NIH temporary custody of the monkeys. That arrangement continues to this day, although the State’s charges have been resolved in the scientist’s favor and the Maryland court’s custody order has expired. After the Maryland prosecution had terminated, NIH moved the monkeys to Louisiana. See
See Lowell Manufacturing v. Export-Import Bank of the United States,
The question whether the Court of Appeals erred in applying Article Ill’s standing requirements to these claims is not before us. See n. 4, infra.
Nor does the Court of Appeals’ decision that petitioners lack Article III standing to protect the monkeys render the dispute surrounding NIH’s removal moot. If removal was improper, the case must be remanded to state court, where the requirements of Article III plainly will not apply.
Our grant of certiorari did not extend to the Court of Appeals’ determination that petitioners lacked standing to protect the monkeys. We therefore leave open the question whether a federal court in a § 1442(a)(1) removal case may require plaintiffs to meet Article Ill’s standing requirements with respect to the state-law claims over which the federal court exercises pendent jurisdiction. See
Mesa
v.
California,
Section 1442(a) reads in pertinent part:
“(a) A civil action or criminal prosecution commenced in a State court against any of the following persons may be removed by them to the district court of the United States for the district and division embracing the place wherein it is pending:
“(1) Any officer of the United States or any agency thereof, or person acting under him, for any act under color of such office or on account of any right, title or authority claimed under any Act of Congress for the apprehension or punishment of criminals or the collection of the revenue.”
Agencies that could sue and be sued in state court included the Federal Crop Insurance Corporation, 52 Stat. 72, 73 (1938); the Farmers Home Corporation, 50 Stat. 522, 527 (1937); and the Reconstruction Finance Corporation, 47 Stat. 5, 6 (1932).
We disregard NIH's other defense that petitioners lack Article III standing. That defense could not be raised in state court, and thus the removal statute is not concerned with its protection. Cf.
Mesa
v.
California,
See,
e. g., FHA
v.
Burr,
Because the case in M. A. I. N. was removed to federal court pursuant to § 1441(b) (original jurisdiction removal) rather than § 1442(a)(1) (federal officer removal), the application of constitutional standing requirements was appropriate. Cf. n. 4, supra.
