428 U.S. 1 (1976)
Twenty-two coal mine operators brought this suit in the United States District Court for the Eastern District of Kentucky against the Secretary of Labor and the Secretary of Health, Education, and Welfare.1
The operators sought declaratory and injunctive relief challenging the constitutionality of Title IV of the Federal Coal Mine Health and Safety Act of 1969, as amended by the Black Lung Benefits Act of 1972.2 The operators faced potential liability under the amended Act to compensate certain miners, former miners, and their survivors for death or total disability due to pneumoconiosis arising out of coal mine employment.3
Coal workers' pneumoconiosis, also known as black lung disease, is caused by long-term inhalation of coal dust.4 It affects a high percentage of American coal miners with severe chronic respiratory impairment.5 The disease is diagnosed primarily through X-ray opacities.6 Post-mortem examinations have shown greater prevalence than X-rays indicate.7 It is classified as simple or complicated.8 The complicated form involves progressive massive fibrosis that produces significant pulmonary impairment.9 It may lead to death by cardiac failure or contribute to other causes.10 The disease is irreversible.11 Its symptoms may appear only after a miner has left the mines.12
Congress responded to the prevalence of the disease by enacting Title II of the 1969 Act to limit dust levels in mines.13 Congress also enacted Title IV to provide benefits to afflicted miners and survivors.14 The benefit provisions were later broadened in 1972.15 Under the amended Act, Part B covers claims filed from December 30, 1969, to June 30, 1973, with benefits paid by the United States.16 Part C covers claims filed after December 31, 1973.17 Those claims are processed under approved state programs or, if none, by the Secretary of Labor with payment by responsible mine operators.18 A transition period from July 1 to December 31, 1973, involves adjudication by the Secretary of Labor with initial federal payment followed by operator liability.19
The Act defines total disability.20 It establishes several presumptions for determining compensable disability.21 These include an irrebuttable presumption under section 411(c)(3) for miners with complicated pneumoconiosis.22 They also include rebuttable presumptions based on years of employment for causation and disability due to the disease.23 The Act limits the use of negative chest X-ray evidence as the sole basis for denying claims.24 It restricts rebuttal evidence in certain cases to showings that the miner does not have pneumoconiosis or that the impairment did not arise from coal mine employment.25
On cross-motions for summary judgment, a three-judge district court upheld most provisions.26 The court found the irrebuttable presumption and the limitation on rebuttal evidence unconstitutional.27 It enjoined the Secretary of Labor from applying them.28 The operators appealed the upheld provisions.29 The federal parties cross-appealed the invalidations.30 The Supreme Court noted probable jurisdiction after granting a stay of the district court's order.31
Whether Title IV of the Federal Coal Mine Health and Safety Act of 1969, as amended by the Black Lung Benefits Act of 1972, violates the Due Process Clause by requiring coal mine operators to compensate miners and survivors for disabilities arising from employment terminated before the Act's enactment?32
Legislative acts adjusting the burdens and benefits of economic life come to the Court with a presumption of constitutionality.33 The burden is on one complaining of a due process violation to establish that the legislature has acted in an arbitrary and irrational way.34 Retrospective aspects of legislation must meet the test of due process.35 The justification for retrospective imposition of liability must take into account possibilities that operators may not have known of the danger and may have relied on the prior state of the law.36
No. The imposition of liability for the effects of disabilities bred in the past is justified as a rational measure to spread the costs of the employees' disabilities to those who have profited from the fruits of their labor.37 Congress could rationally choose to impose the burden on early operators whose profits may have been increased at the expense of employees' health rather than on all operators including new entrants.38
The Due Process Clause poses no bar to requiring an operator to provide compensation for a former employee's death or disability due to pneumoconiosis arising out of employment in its mines, even if the former employee terminated employment before the Act was passed.39

Justice Powell concurred in the judgment but viewed the rationality of retrospective liability as a considerably closer question than the majority suggested.40 He noted that the coal industry is highly competitive and prices are determined by market forces.41 This makes it unlikely that operators enjoyed excess profits in the pre-enactment period that could now be recaptured.42
Powell observed that firms burdened with retroactive payments must meet that expense from current production in a market where prices must be competitive with firms not so burdened.43 The reduced scale of current employment combined with liability to former miners means obligations will be disproportionate to current operations.44 He ultimately concurred because the Operators failed to make factual showings on summary judgment sufficient to override the presumption of constitutionality.45
Whether the Act's definition of total disability is unconstitutionally arbitrary because it compensates miners who may remain employable in other work?46
A miner is totally disabled when pneumoconiosis prevents him from engaging in gainful employment requiring the skills and abilities comparable to those of any employment in a mine or mines in which he previously engaged with some regularity and over a substantial period of time.47 Whether interferences with health and adapted work merit compensation is a public policy matter left primarily to the legislature.48 The Court cannot say they are so insignificant as not to be a rational basis for compensation.49
No. A miner disabled under the statutory standards has suffered in at least two ways.50 His health is impaired.51 He has been rendered unable to perform the kind of work to which he has adapted himself.52 The Court long ago upheld against similar attack a workmen's compensation scheme providing benefits for injuries not depriving the employee of his ability to work.53
It is patent that the attack on the definition must fail because destruction of earning capacity is not the sole legitimate basis for compulsory compensation of employees by their employers.54
The definition of total disability set up in the Act is not unconstitutionally arbitrary or irrational.55
Whether the irrebuttable presumption of total disability due to pneumoconiosis based on clinical evidence of complicated pneumoconiosis denies due process?56
If a miner is suffering or suffered from a chronic dust disease of the lung which when diagnosed by chest roentgenogram yields one or more large opacities or by biopsy or autopsy yields massive lesions, then there shall be an irrebuttable presumption that he is totally disabled due to pneumoconiosis or that his death was due to pneumoconiosis.57 In a statute regulating purely economic matters, Congress' choice of statutory language cannot invalidate the enactment when its operation and effect are clearly permissible.58
No. The effect of the irrebuttable presumption is simply to establish entitlement in the case of a miner who is clinically diagnosable as extremely ill with pneumoconiosis arising out of coal mine employment.59 Were the Act phrased simply to provide that operators were bound to provide benefits for all miners clinically demonstrating their affliction with complicated pneumoconiosis arising out of employment in the mines, there could be no due process objection.60 Since Congress can clearly draft a statute to accomplish precisely what it has accomplished through the presumption, the argument that it has accomplished its result in an impermissible manner fails in a statute regulating purely economic matters.61
The irrebuttable presumption of total disability due to pneumoconiosis based on clinical evidence of complicated pneumoconiosis does not deny due process.62
Whether the rebuttable presumptions of causation and disability based on ten or fifteen years of mine employment are rationally connected to the facts proved?63
A legislative presumption of one fact from evidence of another may not constitute a denial of due process if there is some rational connection between the fact proved and the ultimate fact presumed.64 The inference shall not be so unreasonable as to be a purely arbitrary mandate.65 The process of making the determination of rationality is highly empirical.66 Significant weight should be accorded the capacity of Congress to amass the stuff of actual experience and cull conclusions from it.67
Yes. It is agreed that pneumoconiosis is caused by breathing coal dust.68 The likelihood of developing the disease rests upon both the concentration of dust and the duration of exposure.69 Against this scientific background, it was not beyond Congress' authority to refer to exposure factors in establishing a presumption that throws the burden of going forward on the operators.70
In view of the medical evidence before Congress indicating the noticeable incidence of pneumoconiosis in cases of miners with ten years' employment, it was not purely arbitrary for Congress to select the ten-year figure.71 The fifteen-year point marks the beginning of linear increase in the prevalence of the disease with years spent underground.72
The rebuttable presumptions of causation and disability based on ten or fifteen years of mine employment are constitutionally valid because they rest on a rational connection between the fact proved and the ultimate fact presumed.73
Whether the statutory limitation precluding denial of claims solely on the basis of negative chest X-ray results denies operators due process?74
No claim for benefits shall be denied solely on the basis of the results of a chest roentgenogram.75 Congress has plenary authority over the promulgation of evidentiary rules for the federal courts.76 When it comes to evidentiary rules in matters not within specialized judicial competence, it is primarily for Congress to amass the stuff of actual experience and cull conclusions from it.77
No. Congress was presented with significant evidence demonstrating that X-ray testing that fails to disclose pneumoconiosis cannot be depended upon as a trustworthy indicator of the absence of the disease.78 Autopsy frequently disclosed pneumoconiosis where X-ray evidence had disclosed none.79 Pneumoconiosis may be masked from X-ray detection by other disease.80 Congress addressed the problem by adopting a rule which, while preserving some of the utility, avoided the worst dangers of X-ray evidence.81
The prohibition is only against sole reliance upon negative X-ray evidence in rejecting a claim.82 Negative X-ray evidence remains admissible when taken together with other factors.83
The statutory limitation precluding denial of claims solely on the basis of negative chest X-ray results does not deny operators due process.84
Whether the limitation on rebuttal evidence in section 411(c)(4) applies to operators in transition-period and Part C cases and, if so, is constitutional?85
The Secretary may rebut the presumption only by establishing that the miner does not or did not have pneumoconiosis or that his respiratory or pulmonary impairment did not arise out of or in connection with employment in a coal mine.86 By the language of the section, the limitation applies only to the Secretary and not to an operator seeking to avoid liability.87 This plain language is fortified by the legislative history.88
No. The limitation on rebuttal evidence in section 411(c)(4) is inapplicable to operators.89 The plain language of the section provides that the limitation applies only to the Secretary.90 The reference to the Secretary in Part B means the Secretary of Health, Education, and Welfare, not the Secretary of Labor.91 Even assuming the limitation may bind the Secretary of Labor insofar as he was required to pay benefits for which the United States was liable during the transition period, nothing in the statute or legislative history suggests that an operator is similarly bound.92
The Act does not itself limit the evidence with which an operator may rebut the presumption.93
The limitation on rebuttal evidence in section 411(c)(4) does not apply to operators in transition-period and Part C cases, and the District Court's order invalidating the limitation is vacated.94

Justice Stewart, joined by Justice Rehnquist, dissented from the conclusion that the limitation on rebuttal evidence in section 411(c)(4) is inapplicable to transition determinations under section 415 insofar as those determinations bind operators.95 He argued that section 430 provides that the amendments made by the Black Lung Benefits Act of 1972 to part B shall, to the extent appropriate, also apply to part C.96 The Senate Report stated that new section 430 requires that amendments to part B be applied, wherever appropriate, to part C.97
Stewart contended that the limitation on rebuttal is part and parcel of an elaborate reallocation of the burden of proving disability resulting from pneumoconiosis.98 It is difficult to believe that Congress would have used the phrase to the extent appropriate in section 430 to withdraw the protection of the rebuttal limitation under part C while retaining the rebuttable presumption of which it is an integral part.99
