  Justice Powell
  delivered the opinion of the Court.
  This case requires us to determine whether federal courts have exclusive jurisdiction over personal injury and indemnity cases arising under the Outer Continental Shelf Lands Act, 67 Stat. 462, as amended, 43 U. S. C. § 1331 et seq. (1976 ed. and Supp. III). We also consider whether the rule of Norfolk & Western R. Co. v. Liepelt, 444 U. S. 490 (1980), that the jury be instructed that personal injury damages awards are not subject to federal income taxation, is applicable to such a case.
  I
  Respondent, Mobil Oil Corp., contracted with petitioner, Gulf Offshore Co., for the latter to perform certain completion operations on oil drilling platforms offshore of Louisiana. As part of the agreement, petitioner promised to indemnify Mobil for all claims resulting directly or indirectly from the work. While the work was in progress in September 1975, the advent of Hurricane Eloise required that workers be evacuated from oil platforms in the Gulf of Mexico.
  Steven Gaedecke was an employee of petitioner working on an oil drilling platform above the seabed of the Outer Continental Shelf. As the storm approached, a boat chartered by Mobil took him safely aboard. Shortly thereafter, while assisting crewmen attempting to evacuate other workers from the platforms in turbulent sea, he was washed across the deck of the vessel by a wave. He suffered injuries primarily to his back.
  Gaedecke brought this suit for damages in the District Court of Harris County, a Texas state court, alleging negligence by Mobil and the boatowner. Mobil filed a third-party complaint for indemnification against petitioner. In its third-party answer, petitioner denied that the state court had subject-matter jurisdiction over the third-party complaint. Petitioner argued that Mobil’s cause of action arose under the Outer Continental Shelf Lands Act (OCSLA), and that OCSLA vested exclusive subject-matter jurisdiction in a United States district court. The Texas trial court rejected this contention, and the case went to trial before a jury.
  In submitting the case to the jury, the trial court denied a request by petitioner to instruct them that personal injury damages awards are not subject to federal income taxation and that they should not increase or decrease an award in contemplation of tax consequences. The jury found Mobil negligent and awarded Gaedecke $900,000 for his injuries. The jury also found, however, that Gaedecke sustained his injuries while performing work subject to the contract of indemnification. Based on the two verdicts, the trial judge entered judgment against petitioner in the amount of $900,000.
  The Texas Court of Civil Appeals affirmed. 594 S. W. 2d 496 (1979). It held that the Texas state courts had subject-matter jurisdiction over the causes of action. It acknowledged that OCSLA governed the case, but found no explicit command in the Act that federal-court jurisdiction be exclusive. The court also observed that exclusive federal-court jurisdiction was unnecesary because the Act incorporates as federal law in personal injury actions the laws of the State adjacent to the scene of the events, when not inconsistent with other federal laws. 43 U. S. C. § 1333 (a)(2). Thus, the court reasoned, “[t]he end result would be an application of the same laws no matter where the forum was located, whether state or federal.” 594 S. W. 2d, at 502. The court also held that the trial court did not err in refusing to instruct the jury that damages awards are not subject to federal income taxation. The Texas Supreme Court denied review.
  We granted certiorari to resolve a conflict over whether federal courts have exclusive subject-matter jurisdiction over suits arising under OCSLA and to consider whether an instruction that damages are not taxable is appropriate in such a case. 449 IT. S. 1033 (1980).
  II
  A
  The general principle of state-court jurisdiction over cases arising under federal laws is straightforward: state courts may assume subject-matter jurisdiction over a federal cause of action absent provision by Congress to the contrary or disabling incompatibility between the federal claim and state-court adjudication. Charles Dowd Box Co. v. Courtney, 368 U. S. 502, 507-508 (1962); Claflin v. Houseman, 93 U. S. 130, 136 (1876). This rule is premised on the relation between the States and the National Government within our federal system. See The Federalist No. 82 (Hamilton). The two exercise concurrent sovereignty, although the Constitution limits the powers of each and requires the States to recognize federal law as paramount. Federal law confers rights binding on state courts, the subject-matter jurisdiction of which is governed in the first instance by state laws.
  In considering the propriety of state-court jurisdiction over any particular federal claim, the Court begins with the presumption that state courts enjoy concurrent jurisdiction. See California v. Arizona, 440 U. S. 59, 66-67 (1979); Charles Dowd Box Co. v. Courtney, 368 U. S., at 507-508. Congress, however, may confine jurisdiction to the federal courts either explicitly or implicitly. Thus, the presumption of concurrent jurisdiction can be rebutted by an explicit statutory directive, by unmistakable implication from legislative history, or by a clear incompatibility between state-court jurisdiction and federal interests. See ibid.; Claflin, supra, at 137. See also Garner v. Teamsters, 346 U. S. 485 (1953) (grievance within jurisdiction of National Labor Relations Board to prevent unfair labor practice not subject to relief by injunction in state court).
  B
  No one argues that Congress explicitly granted federal courts exclusive jurisdiction over cases arising under OCSLA. Congress did grant United States district courts “original jurisdiction of cases and controversies arising out of or in connection with any operations conducted on the outer Continental Shelf . . . 43 U. S. C. § 1333 (b). It is black letter law, however, that the mere grant of jurisdiction to a federal court does not operate to oust a state court from concurrent jurisdiction over the cause of action. United States v. Bank of New York & Trust Co., 296 U. S. 463, 479 (1936).
  OCSLA declares the Outer Continental Shelf to be an area of “exclusive federal jurisdiction.” 43 U. S. C. § 1333 (a) (1). Chevron Oil Co. v. Huson, 404 U. S. 97, 100 (1971). Petitioner does contend that the assertion of exclusive political jurisdiction over the Shelf evinces a congressional intent that federal courts exercise exclusive jurisdiction over controversies arising from operations on the Shelf. See Fluor Ocean Services, Inc. v. Rucker Co., 341 F. Supp. 757, 760 (ED La. 1972). This argument is premised on a perceived incompatibility between exclusive federal sovereignty over the Outer Continental Shelf and state-court jurisdiction over controversies relating to the Shelf. We think petitioner mistakes the purpose of OCSLA and the policies necessitating exclusive federal-court jurisdiction.
  OCSLA extends the “Constitution and laws and civil and political jurisdiction of the United States” to the subsoil and seabed of the Outer Continental Shelf and to “artificial islands and fixed structures” built for discovery, extraction, and transportation of minerals. 43 U. S. C. § 1333 (a)(1). All law applicable to the Outer Continental Shelf is federal law, but to fill the substantial “gaps” in the coverage of federal law, OCSLA borrows the “applicable and not inconsistent” laws of the adjacent States as surrogate federal law. § 1333 (a) (2); Rodrigue v. Aetna Casualty Co., 395 U. S. 352, 355-359 (1969). Thus, a personal injury action involving events occurring on the Shelf is governed by federal law, the content of which is borrowed from the law of the adjacent State, here Louisiana. See id., at 362-365. Cf. United States v. Kimbell Foods, Inc., 440 U. S. 715 (1979) (state law incorporated as federal common law concerning priority of liens created by federal law).
  The OCSLA plan is not inimical to state-court jurisdiction over personal injury actions. Nothing inherent in exclusive federal sovereignty over a territory precludes a state court from entertaining a personal injury suit concerning events occurring in the territory and governed by federal law. Ohio River Contract Co. v. Cordon, 244 U. S. 68 (1917). See 16 U. S. C. § 457 (personal injury and wrongful-death actions involving events occurring “within a national park or other place subject to the exclusive jurisdiction of the United States, within the exterior boundaries of any State” shall be maintained as if the place were under the jurisdiction of the State). Cf. Evans v. Cornman, 398 U. S. 419, 424 (1970) (residents of an area of exclusive federal jurisdiction within a State are “subject to the process and jurisdiction of state courts”). “The judiciary power of every government looks beyond its own local or municipal laws, and in civil cases lays hold of all subjects of litigation between parties within its jurisdiction, though the causes of dispute are relative to the laws of the most distant part of the globe.” The Federalist No. 82, p. 514 (H. Lodge ed. 1908) (Hamilton), quoted in Claflin v. Houseman, 93 U. S., at 138. State courts routinely exercise subject-matter jurisdiction over civil cases arising from events in other States and governed by the other States’ laws. See, e. g., Dennick v. Railroad Co., 103 U. S. 11 (1881). Cf. Allstate Ins. Co. v. Hague, 449 U. S. 302 (1981). That the location of the event giving rise to the suit is an area of exclusive federal jurisdiction rather than another State, does not introduce any new limitation on the forum State’s subject-matter jurisdiction. Ohio River Contract Co. v. Gordon, supra, at 72.
  Section 1333 (a) (3) provides that “adoption of State law as the law of the United States shall never be interpreted as a basis for claiming any interest in or jurisdiction on behalf of any State for any purpose over the seabed and subsoil of the outer Continental Shelf, or the property and natural resources thereof or the revenues therefrom.” Petitioner argues that state-court jurisdiction over this personal injury case would contravene this provision. This argument again confuses the political jurisdiction of a State with its judicial jurisdiction. Section 1333 (a)(3) speaks to the geographic boundaries of state sovereignty, because Congress primarily was concerned in enacting OCSLA to assure federal control over the Shelf and its resources. See n. 7, supra. The language of the provision refers to “any interest in or jurisdiction over” real property, minerals, and revenues, not over causes of action. Indeed, opponents of OCSLA urged Congress to extend the political boundaries of the States seaward over the Shelf, at least for some purposes. See 99 Cong. Rec. 7230 (remarks of Sen. Ellender), 7232 (remarks of Sen. Long) (1953). The Senate Report explains that § 1333 (a)(3) was intended to make plain that the adoption of state law as federal law cannot be the basis for a claim by the State “for participation in the administration of or revenues from the areas outside of State boundaries.” 1953 S. Rep., at 23.
  We do not think the legislative history of OCSLA can be read to rebut the presumption of concurrent state-court jurisdiction, given Congress’ silence on the subject in the statute itself. Petitioner relies principally on criticisms by the two Senators from Louisiana, Ellender and Long, who opposed the bill that eventually became OCSLA. Yet “[t]he fears and doubts of the opposition are no authoritative guide to the construction of legislation.” Schwegmann Bros. v. Calvert Distillers Corp., 341 U. S. 384, 394 (1951). Moreover, the amendments offered by the Senators sought to confer political control over the Shelf and its mineral wealth on the States, not jurisdiction on the state courts over OCSLA cases. See 99 Cong. Rec. 7230 (Sen. Ellender), 7232 (Sen. Long) (1953).
  C
  The operation of OCSLA will not be frustrated by state-court jurisdiction over personal injury actions. The factors generally recommending exclusive federal-court jurisdiction over an area of federal law include the desirability of uniform interpretation, the expertise of federal judges in federal law, and the assumed greater hospitality of federal courts to peculiarly federal claims. These factors cannot support exclusive federal jurisdiction over claims whose governing rules are borrowed from state law. There is no need for uniform interpretation of laws that vary from State to State. State judges have greater expertise in applying these laws and certainly cannot be thought unsympathetic to a claim only because it is labeled federal rather than state law.
  Allowing personal injury and contract actions in state courts will advance interests identified by Congress in enacting OCSLA. A recurring consideration in the deliberations leading to enactment was “the special relationship between the men working on these [platforms] and the adjacent shore to which they commute to visit their families.” Rodrigue v. Aetna Casualty Co., 395 U. S., at 365. Allowing state-court jurisdiction over these cases will allow these workers, and their lawyers, to pursue individual claims in familiar, convenient, and possibly less expensive fora. See Chevron Oil Co. v. Huson, 404 U. S., at 103 (state statute of limitations applies to personal injury actions arising under OCSLA).
  In summary, nothing in the language, structure, legislative history, or underlying policies of OCSLA suggests that Congress intended federal courts to exercise exclusive jurisdiction over personal injury actions arising under OCSLA. The Texas courts had jurisdiction over this case.
  Ill
  The Court of Civil Appeals held that petitioner was not entitled to an instruction cautioning the jury that personal injury damages awards are not subject to federal income taxation, § 104 (a) (2) of the Internal Revenue Code of 1954, 26 U. S. C. §104 (a)(2). In so ruling the court relied on Johnson v. Penrod Drilling Co., 510 F. 2d 234, 236-237 (CA5) (en banc) (per curiam), cert. denied, 423 U. S. 839 (1975), a Jones Act case where the Court of Appeals prohibited presenting evidence or instructing the jury as to the impact of taxes on damages awards based on lost wages. This Court subsequently held that a defendant in a suit brought under the Federal Employers’ Liability Act (FELA), 45 U. S. C. § 51 et seq., is entitled to an instruction that damages for lost future wages are not subject to federal income taxation. Norfolk & Western R. Co. v. Liepelt, 444 U. S. 490 (1980). Petitioner now argues that Liepelt applies to an OCSLA personal injury action and that this case should be remanded for a new trial on damages before a properly instructed jury.
  Our first task is to determine the source of law that will govern whether such an instruction must be available in an OCSLA case. OCSLA, as discussed above, mandates that state laws apply as federal laws “[t]o the extent that they are applicable and not inconsistent with this subchapter or with other Federal laws.” 43 U. S. C. § 1333 (a)(2). In any particular case, the adjacent State’s law applies to those areas “which would be within the area of the State if its boundaries were extended seaward to the outer margin of the outer Continental Shelf . . . Ibid. The statute thus contains air explicit choice-of-law provision. See n. 8, supra. The parties agree that the substantive law of Louisiana applies to this case, unless it is inconsistent with federal law.
  To apply the statutory directive a court must consider the content of both potentially applicable federal and state law. Subsequent to the decision of the Texas court, as noted above, we held in Liepelt, supra, that a defendant in an FELA case is entitled to an instruction that damages awards are not subject to federal income taxation. As FELA afforded no guidance on this issue, the holding articulated a federal common-law rule. The purpose was to eliminate from the deliberations of juries “an area of doubt or speculation that might have an improper impact on the computation of the amount of damages.” 444 U. S., at 498. Thus, the instruction furthers strong federal policies of fairness and efficiency in litigation of federal claims. If Congress had been silent about the source of federal law in an OCSLA personal injury case, Liepelt would require that the instruction be given.
  But Congress was not silent. It incorporated for this case the applicable law of Louisiana, but only “[t]o the extent [it is] not inconsistent” with federal law. The statute does not distinguish between federal statutory and judge-made law. It would seem then that if Louisiana law is “inconsistent,” Liepelt controls. Doubt arises, however, because in OCSLA Congress borrowed a remedy provided by state law and thereby “specifically rejected national uniformity” as a paramount goal. Chevron Oil v. Huson, 404 U. S., at 104. In Chevron, we held that Louisiana rather than federal common law provided the federal statute of limitations for personal injury damages actions under OCSLA. We recognized that “Congress made clear provision for filling the ‘gaps’ in federal law; it did not intend that federal courts fill those 'gaps’ themselves by creating new federal common law.” Id., at 104M05. In this case, we face an analogous question: does the incorporation of state law preclude a court from finding that state law is “inconsistent” with a federal common-law rule generally applicable to federal damages actions?
  We need answer this question only if Louisiana law would not require that the instruction be given upon timely request. The court below never addressed this question but relied solely on federal case law now superseded. Under these circumstances it is the better practice to remand this case to the Texas Court of Civil Appeals for a determination of whether Louisiana law requires the instruction and, if it does not, whether Liepelt displaces the state rule in an OCSLA case. If the court decides that it was error to refuse the instruction, it may then address respondents’ argument that petitioner was not prejudiced by the error.
  Affirmed in part, vacated in part, and remanded.
  Justice Stewart took no part in the consideration or decision of this case.
  Mobil claimed indemnification on the grounds of both its contract with petitioner and the allegation that petitioner’s negligence caused the accident. Prior to trial Gaedecke entered into a conditional settlement agreement with Mobil, which limited his potential recovery against Mobil to $200,000; in return Mobil agreed to proceed against petitioner for indemnification only on the basis of the contract. Gaedecke also settled his claim with the boatowner.
  Texas had in personam jurisdiction over Mobil and petitioner, each of whom does business in Texas. Gaedecke was a resident of Harris County, Tex.
  See Pool v. Kemper Ins. Group, 386 So. 2d 1006 (La. App. 1980) ; Friedrich v. Whittaker Corp., 467 F. Supp. 1012 (SD Tex. 1979); Gravois v. Travelers Indemnity Co., 173 So. 2d 550 (La. App. 1965). See also Fluor Ocean Services, Inc. v. Rucker Co., 341 F. Supp. 757, 760 (ED La. 1972).
  Permitting state courts to entertain federal causes of action facilitates the enforcement of federal rights. If Congress does not confer jurisdiction on federal courts to hear a particular federal claim, the state courts stand ready to vindicate the federal right, subject always to review, of course, in this Court. See Martin v. Hunter’s Lessee, 1 Wheat. 304, 346-348 (1816). This practical concern was more important before the statutory creation in 1875 of general federal-question jurisdiction.
  Congress amended and recodified the jurisdictional provisions of OCSLA in 1978, without effecting any change that casts light on the issue of exclusive federal-court jurisdiction before us today. Pub. L. 95-372, Title II, §208 (b), 92 Stat. 657. See S. Conf. Rep. No. 95-1091, p. 114 (1978). But cf. Pub. L. 95-372, Title II, §208 (a)(2)(B), 92 Stat. 657 (contemplating suit by the Attorney General in state court to remedy violations of the Act). The grant of jurisdiction to a federal district court is now codified at 43 U. S. C. § 1349 (b)(1) (1976 ed., Supp. III). In this opinion, we employ the Code citations prior to the recodification.
  This principle defeats petitioner’s reliance on the provision in § 1333 (a) (2): “All of such applicable laws shall be administered and enforced by the appropriate officers and courts of the United States.” The phrase “such applicable laws” refers to the laws of the adjacent States, which § 1333 (a) (2) incorporates as federal law for the Outer Continental Shelf. See infra, at 480-481. The language relied upon merely makes clear that these borrowed state laws are to be enforced like other federal laws, and nothing indicates an intent to exclude state courts from the subject-matter jurisdiction they exercise generally over federal claims.
  The legislative history confirms that the purpose of OCSLA was “to assert the exclusive jurisdiction and control of the Federal Government of the United States over the seabed and subsoil of the outer Continental Shelf, and to provide for the development of its vast mineral resources.” S. Rep. No. 411, 83d Cong., 1st Sess., 2 (1953) (hereinafter 1953 S. Rep.). Congress enacted OCSLA in the wake of decisions by this Court that the Federal Government enjoyed sovereignty and ownership of the seabed and subsoil of the Outer Continental Shelf to the exclusion of adjacent States. See United States v. Texas, 339 U. S. 707 (1950); United States v. Louisiana, 339 U. S. 699 (1950). See also United States v. California, 332 U. S. 19 (1947). See generally Maryland v. Louisiana, 451 U. S. 725, 730 (1981). Congress chose to retain exclusive federal control of the administration of the Shelf because it underlay the high seas and the assertion of sovereignty there implicated the foreign policies of the Nation. See 1953 S. Rep., at 6. Much of OCSLA provides a federal framework for the granting of leases for exploration and extraction of minerals from the submerged lands of the Shelf. See 43 U. S. C. §§ 1334^1343.
  Congress was not unaware, however, of the close, longstanding relationship between the Shelf and the adjacent. States. See 1953 S. Rep., at 6. This concern manifested itself primarily in the incorporation of the law of adjacent States to fill gaps in federal law. See Rodrigue v. Aetna Casualty Co., 395 U. S. 352, 365 (1969). It should be emphasized that this case only involves state-court jurisdiction over actions based on incorporated state law. We express no opinion on whether state courts enjoy concurrent jurisdiction over actions based on the substantive provisions of OCSLA.
  OCSLA does supersede the normal choice-of-law rules that the forum would apply. See Chevron Oil Co. v. Huson, 404 U. S. 97, 102-103 (1971). It also provides where proper venue will be found: “in the judicial district in which any defendant resides or may be found, or in the judicial district of the State nearest the place the cause of action arose.” 43 U. S. C. §1349 (b)(1) (1976 ed., Supp. III).
  Petitioner also relies on a report made to the Senate Committee by the Department of Justice, which argued that the Federal Government should “have the exclusive control of lawmaking and law enforcement” on the Shelf. 1953 S. Rep., at 6. But Congress rejected the Department’s premise that the Shelf is “not comparable to . . . federally owned areas within a State.” Ibid. See Rodrigue v. Aetna Casualty Co., 395 U. S., at 365. Section 1333 (a)(1) rather provides that the federal laws apply to the Shelf “to the same extent as if the outer Continental Shelf were an area of exclusive Federal jurisdiction located within a State.”
  Senator Long did express the fear that OCSLA placed exclusive jurisdiction over all civil suits in federal district courts. 1953 S. Rep., at 66 (minority report); 99 Cong. Rec. 7233 (1953).
  Most of the Senators’ statements regarding OCSLA’s effect on state-court jurisdiction criticize placing exclusive criminal jurisdiction in federal courts. See, e. g., id., at 7231-7232 (Sen. Ellender). But the statute that gives federal courts exclusive jurisdiction over federal crimes, 18 U. S. C. § 3231, has no relevance to this case.
  Exclusive federal-court jurisdiction over a cause of action generally is unnecessary to protect the parties. The plaintiff may choose the available forum he prefers, and the defendant may remove the case if it could have been brought originally in a federal court. 28 U. S. C. § 1441 (b). Also, exclusive federal jurisdiction will not prevent a state court from deciding a federal question collaterally even if it would not have subject-matter jurisdiction over a case raising the question directly. See Note, Exclusive Jurisdiction of Federal Courts in Private Civil Actions, 70 Harv. L. Rev. 509, 510 (1957).
  See Redish & Muench, Adjudication of Federal Causes of Action in State Court, 75 Mich. L. Rev. 311, 329-335 (1976); Note, 70 Harv. L. Rev., supra n. 12, at 511-515.
  Liepelt also found error in the trial court’s refusal to allow the defendant to introduce evidence showing the effect of income taxes on the plaintiff’s future earnings. 444 U. S., at 493-496. This case does not present the question whether this second holding is applicable to OCSLA cases.
  Respondents argue that we cannot address the necessity of giving the requested instruction because petitioner did not preserve its objection in the trial court in the manner required by Texas law. This argument is incorrect. The Texas Court of Civil Appeals held on the merits that petitioner was not entitled to the instruction.
  We also reject respondents’ contention that we are foreclosed from deciding the issue because petitioner did not introduce any evidence about the effect of taxation on Gaedecke’s future earnings. No evidentiary predicate is required to instruct a jury not to consider taxes.
  Respondents’ argument that Liepelt should apply prospectively only is insubstantial. Here, we address a change in the law occurring while the case is on direct appeal. "[A]n appellate court must apply the law in effect at the time it renders its decision.” Thorpe v. Housing Authority of City of Durham, 393 U. S. 268, 281 (1969); see United States v. Schooner Peggy, 1 Cranch 103 (1801). While there well might be an exception to the rule to prevent “manifest injustice,” Bradley v. Richmond School Board, 416 U. S. 696, 717 (1974), this equitable exception does not reach a private civil suit where the change does not extinguish a cause of action but merely requires a retrial on damages before a properly instructed jury. Lang v. Texas & Pacific R. Co., 624 F. 2d 1275, 1279-1280, and n. 9 (CA5 1980). Indeed, considerations of fairness support retroactive application: failure to give the instruction may lead to the plaintiff recovering a windfall award. Norfolk & Western R. Co. v. Liepelt, supra, at 497-498.
  The overwhelming weight of authority supports retroactive application of this decision. See O’Byrne v. St. Louis Southwestern R. Co., 632 F. 2d 1285 (CA5 1980); Flanigan v. Burlington Northern Inc., 632 F. 2d 880 (CA8 1980); Lang v. Texas & Pacific R. Co., supra; Crabtree v. St. Louis-San Francisco R. Co., 89 Ill. App. 3d 35, 411 N. E. 2d 19 (1980). Other eases have applied Liepelt retroactively without comment. Cazad v. Chesapeake & Ohio R. Co., 622 F. 2d 72 (CA4 1980); Seaboard Coast Line R. Co. v. Yow, 384 So. 2d 13 (Ala. 1980). But see Ingle v. Illinois Central Gulf R. Co., 608 S. W. 2d 76 (Mo. App. 1980), cert. denied, 450 U. S. 916 (1981).
  The general applicability of Liepelt is indicated by the Court’s quotation with approval of the explanation of need for the instruction in Domeracki v. Humble Oil & Refining Co., 443 F. 2d 1245, 1251 (CA3), cert. denied, 404 U. S. 883 (1971), a longshoreman’s action based on the unseaworthiness of a vessel.
  “ ‘We take judicial notice of the “tax consciousness” of the American public. Yet, we also recognize, as did the court in Dempsey v. Thompson, 363 Mo. 339, 251 S. W. 2d 42 (1952), that few members of the general public are aware of the special statutory exemption for personal injury awards contained in the Internal Revenue Code.
  “ ‘ “[T]here is always danger that today’s tax-conscious juries may assume (mistakenly of course) that the judgment will be taxable and therefore make their verdict big enough so that plaintiff would get what they think he deserves after the imaginary tax is taken out of it.”
  “TI Harper & James, The Law of Torts §25.12, at 1327-1328 (1956).’” Liepelt, supra, at 497.
  None of the Court’s reasoning was directed particularly at FELA.
  The Louisiana eases that have come to our attention do not provide conclusive guidance. Compare the earlier case of Guerra v. Young Construction Corp., 165 So. 2d 882 (La. App. 1964) (not error to deny the instruction), with the later cases of DeBose v. Trapani, 295 So. 2d 72 (La. App. 1974), and Francis v. Government Employers’ Ins. Co., 376 So. 2d 609 (La. App. 1979) (proper to give the instruction). These Louisiana cases were considered by the Court of Appeals for the Fifth Circuit in a diversity case, Croce v. Bromley Corp., 623 F. 2d 1084 (1980), cert. denied sub nom. Bromley Corp. v. Cortese, 450 U. S. 981 (1981), and it followed the holding in Guerra.
