Validity and Influence of ADA Regulations (PDF, 141K)

June 4, 2003

In the modern American governmental system, Congress often shares some of its lawmaking powers with the executive branch. Congress commonly delegates to executive agencies the power to fill in gaps and to develop more precise standards for carrying out the laws it enacts. A primary way in which executive branch agencies exercise this delegated authority is by issuing regulations. In the Americans with Disabilities Act (ADA), Congress assigned several federal agencies the task of issuing regulations for carrying out the Act's requirements. The Equal Employment Opportunity Commission (EEOC) was directed to issue regulations for implementing Title I, the employment provisions of the ADA.1 As the head of the Department of Justice (DOJ), the Attorney General was charged with issuing regulations both for carrying out Title II's requirements regarding state and local government entities,2 and for implementing the requirements Title III places on public accommodations.3 The Secretary of Transportation was made responsible for issuing regulations for the implementation of the ADA's transportation requirements both for state and local government entities under Title II4 and public accommodations under Title III..5 The Federal Communications Commission (FCC) was directed to issue and enforce regulations for carrying out Title IV's requirements regarding telephone relay services.6

The Supreme Court has fluctuated greatly in the degree of respect it has accorded the regulations these agencies have issued in fulfillment of their ADA responsibilities. This policy brief in the National Council on Disability's (NCD) Righting the ADA series examines the status the Court has conferred on the various sets of ADA regulations and how solicitous or dismissive it has been in following the standards established in the regulations. It is important at the outset to understand the difference between the level of deference the Court deems appropriate for a particular set of regulations and the extent to which the Court follows or applies a particular regulatory requirement or interpretation.

Traditionally, courts have recognized that "considerable weight should be accorded to an executive department's construction of a statutory scheme it is entrusted to administer ...."7 In its decision in the case of Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc.8 in 1984, the Supreme Court offered more specific guidance regarding the extent to which courts should defer to policy choices in regulations. The Court said that whenever Congress, in enacting a statute, expressly directs an executive agency to issue regulations to fill in gaps in the statutory provisions, the regulatory provisions issued by the agency are to be "given controlling weight unless they are arbitrary, capricious, or manifestly contrary to the statute."[9 In situations where the congressional delegation to an executive agency to fill in a statutory gap is only implicit, the agency's regulatory provisions are still entitled to considerable weight. According to the Court inChevron, courts may not substitute their own construction of a statutory provision "for the reasonable interpretation made by the administrator of an agency."10 These high degrees of authoritativeness of regulations have subsequently come to be called "Chevron deference."

But even if a provision in regulations is entitled to Chevron deference, courts still do not always have to follow it. A court should not defer to a regulatory provision that is contrary to the statute; that is unreasonable, arbitrary, or capricious; or that is beyond the scope of the jurisdiction of the agency that issued the regulation. Accordingly, although the two are often interrelated, the level of deference a court assigns to a regulation is a separate issue from whether the court ultimately accepts and applies a regulatory provision's position on a specific policy matter.

The Supreme Court's treatment of ADA regulatory provisions interpreting the definitions found at the beginning of the Act has been dramatically different from its treatment of provisions addressing substantive requirements of the Act. For this reason, these two categories of regulations will be discussed separately in this policy brief.


After preliminary sections of the Act presenting the short title of the Act, a table of contents, congressional findings, and a statement of the purposes of the law, the first provisions of the ADA are definitions of three important terms used in the statute: "auxiliary aids and services," "disability," and "state.11 As many of the prior policy briefs in NCD's Righting the ADA series have discussed, the Supreme Court has devoted considerable attention to the definition of the term "disability." In doing so, the Court has been highly inconsistent in its attitude toward regulations implementing this definition.

Level of Deference

In Bragdon v. Abbott, 524 U.S. 624 (1998), the Court considered whether asymptomatic HIV infection met the Act's definition of disability. Among other authorities that the Court looked to to resolve this issue were the regulations issued by the Department of Justice under Title III of the ADA. The Court said that these regulations should be accorded Chevrondeference.12 The specific regulatory provisions the Court was referring to in Bragdon were those addressing the definition of disability. The Court also was able to "draw guidance from the views of the agencies authorized to administer other sections of the ADA," and cited EEOC's Title I regulations, DOJ's Title II regulations, and DOT's regulations implementing the transportation-related provisions of Titles II and III.13 In each instance, the Court was discussing the regulations and regulatory guidance of those agencies clarifying elements of the definition of disability.

In Sutton v. United Airlines, 527 U.S. 471 (1999), on the other hand, the Court accorded considerably less value to the provisions in EEOC's ADA regulations addressing the definition of disability. The Court discussed the various delegations of authority to issue regulations under Titles I to V of the ADA, and then declared that "[n]o agency, however, has been given authority to issue regulations implementing the generally applicable provisions of the ADA, ... which fall outside Titles I-V. Most notably, no agency has been delegated authority to interpret the term `disability.'"14 However, because both parties in Sutton accepted the EEOC regulations defining "disability" as valid, and the Court determined that the validity of the regulations was not necessary to decide the case, it declined to determine "what deference they are due, if any."15

In his dissenting opinion in Sutton, Justice Breyer contended that the majority's questioning of EEOC's authority was unnecessarily and inappropriately technical:

There is no reason to believe that Congress would have wanted to deny the EEOC the power to issue such a regulation, at least if the regulation is consistent with the earlier statutory definition and with the relevant interpretations by other enforcement agencies. The physical location of the definitional section seems to reflect only drafting or stylistic, not substantive, objectives. And to pick and choose among which of [Title I's] words the EEOC has the power to explain would inhibit the development of law that coherently interprets this important statute.16

Actually, the placement of the ADA's definitions section at the beginning of the Act rather than within one of the substantive Titles serves what one would have thought is a fairly obvious purpose. The terms defined there are ones that are used in more than one of the substantive Titles of the Act; this is in contrast to other terms, such as "employer," "public entity," "public accommodation," "TDD," and a number of others that are defined within the particular Title in which they are used. The term "disability" in particular is used in various provisions throughout the Act. Rather than repeating the identical statutory definition of disability within each of the Titles in which it is used, Congress considered it much more efficient to include the definition at the beginning.

At the same time, since the term "disability" is used within different Titles with differing contexts, histories, and complexities, it was appropriate for Congress to authorize the agency charged with issuing regulations implementing each of the Titles to include within its regulations provisions making the definition of disability clear to covered entities, and to add regulatory clarifications or interpretive guidance that might arise from the differing contexts and purposes of the particular Title. This approach had the advantage of adopting a single definition of disability while leaving open the possibility of variations on its application tailored to the particular regulatory setting. The conclusion of the Court in Suttonthat Congress did not delegate authority for regulations interpreting the definition of disability to any agency seems to ignore the seemingly evident congressional objective in organizing the statute the way it did.

In Murphy v. United Parcel Service, 527 U.S. 516 (1999), the Court followed the Sutton opinion in assuming without deciding that EEOC's Title I regulations are valid.17 Likewise, in Albertson's, Inc. v. Kirkingburg, 527 U.S. 555 (1999), the Court declared:

As the parties have not questioned the regulations and interpretive guidance promulgated by the EEOC relating to the ADA's definitional section, for the purposes of this case, we assume, without deciding, that such regulations are valid, and we have no occasion to decide what level of deference, if any, they are due, see Sutton v. United Airlines, Inc.18

In Toyota Motor Manufacturing, Kentucky, Inc. v. Williams, 122 S.Ct. 681 (2002), the Court again followed its approach inSutton, Murphy, and Kirkingburg in reiterating that the ADA did not assign any agency authority to issue regulations interpreting the term "disability," but deciding, since the parties had accepted the EEOC ADA regulations as reasonable, to assume without deciding that they were valid, without deciding "what level of deference, if any," they were due.19Ironically, the Court stated that regulations interpreting the Rehabilitation Act of 1973 were entitled to considerable persuasive authority in interpreting the ADA. The Court noted that the ADA's definition of disability was drawn nearly verbatim from the definition of "handicapped individual" in the Rehabilitation Act, 29 U.S.C. § 706(8)(B), and observed that "Congress' repetition of a well-established term generally implies that Congress intended the term to be construed in accordance with pre-existing regulatory interpretations."20 But having recognized the significance of Rehabilitation Act regulations in interpreting the ADA, the Court considered the persuasive authority of the EEOC's ADA regulations regarding the definition of disability as "less clear."21

In its Sutton, Murphy, Kirkingburg, and Williams decisions, the Court took pains to declare that it was assuming, without deciding, that the regulatory provisions interpreting the definition of disability were valid, and that, if valid, it was not deciding what level of deference, if any, they should be accorded. This dubious, begrudging recognition of the regulations' authority is in sharp contrast to the Court's opinion in Bragdon where the Court held the regulations entitled to a high level of judicial deference.

Acceptance and Application of Regulatory Standards

The Court has been equally variable in the extent to which it has followed the specific standards issued by the ADA regulatory agencies interpreting the definition of disability. It has flatly rejected the agencies' position on mitigating measures. In its decision in the Sutton case, the Court repudiated the position taken in regulatory guidance of both the EEOC and DOJ - that persons are to be evaluated in their uncorrected state without taking mitigating measures into account. The Court ruled that "by its terms, the ADA cannot be read in this manner" and concluded that the agencies' view was "an impermissible interpretation of the ADA."22 The Court's decisions in Murphy and Kirkingburg followed the Suttonruling in rejecting the EEOC's and DOJ's position on mitigating measures.23 The Court's problematic analysis of the mitigating measures issue is discussed in another policy brief in NCD's Righting the ADA series; it is found

Ironically, in its Sutton decision, after questioning the EEOC's authority to issue regulations implementing the definition of disability and rejecting the EEOC's position on the mitigating measures issue, the Court accepted (though without ruling on their validity) EEOC's regulatory provisions and regulatory guidance providing (as part of the disability determination) that inability to perform a single, particular job does not constitute a substantial limitation in the major life activity of working.24Likewise, in the Murphy case, the Court followed the EEOC's position on the necessity of demonstrating inability to perform a broad range or class of jobs.25 In Williams, the Court again recited the EEOC not-just-one-job standard, but held that the criterion of inability to perform a class or broad range of activities should not be applied to major life activities other than working.26 The Court's treatment of this issue is discussed in another policy brief in NCD's Righting the ADAseries; it is found at

The Court has been indecisive and somewhat inconsistent about whether it will accept the position of the ADA regulatory agencies on a third issue - recognition of working as a major life activity. In Bragdon v. Abbott, all the members of the Court, in various opinions, discussed working as a major life activity.27 Yet in Sutton the Court indicated that it was "[a]ssuming without deciding that working is a major life activity ....," and added that it had certain misgivings:

We note, however, that there may be some conceptual difficulty in defining "major life activities" to include work, for it seems "to argue in a circle to say that if one is excluded, for instance, by reason of [an impairment, from working with others] ... then that exclusion constitutes an impairment, when the question you're asking is, whether the exclusion itself is by reason of handicap." Tr. of Oral Arg. in School Bd. of Nassau Co. v. Arline, O.T. 1986, No. 85-1277, p. 15 (argument of Solicitor General).

In Murphy v. United Parcel Service, 527 U.S. 516, 523 (1999), the Court again stated that it would assume without deciding that regulations delineating "working" as a major life activity are valid. And in Toyota Motor Manufacturing, Kentucky, Inc. v. Williams, 122 S.Ct. 681 (2002), although the Court initially stated that it would "express no opinion" on the contention that working was a major life activity,28 the Court again asserted its reluctance to recognize working as a major life activity. The Court declared:

Because of the conceptual difficulties inherent in the argument that working could be a major life activity, we have been hesitant to hold as much, and we need not decide this difficult question today. Id. at 692.

The Court's wavering and skeptical positions on the issue of working as a major life activity is discussed in another policy brief in the National Council on Disability's Righting the ADA series; it is found

On a fourth issue arising under the definition of disability - the meaning of the term "substantially limits" - the Court has substituted its own formulation for the one established in the Title I regulations issued by the EEOC. In its decision inToyota Motor Manufacturing, Kentucky, Inc. v. Williams, the Court announced that to have a disability an individual must have an impairment that "prevents or severely restricts" the individual from performing major life activities. The Court's phrasing represents a more restrictive standard than the EEOC phrasing that required only a "significant restriction" which the Court had previously accepted in Kirkingburg. This redefinition is discussed in more detail in another policy brief in NCD's Righting the ADA series; it is found at

Accordingly, while the Court has fluctuated somewhat, particularly in retrenching from its initial broad view of the definition of disability in Bragdon, it ultimately has tended not to follow the administrative agencies on issues in which they have taken a more inclusive view of the definition. In four issues arising under the definition, the Court has rejected the regulatory agencies' position on one (mitigating measures), questioned their stance on a second (working as a major life activity), adopted its own more restrictive definition in preference to the EEOC's definition in a third (substantial limitation), and accepted the regulatory agencies' position on the fourth (EEOC's restrictive one-job-is-not-enough standard).


The Court has usually accorded the ADA regulations relatively favorable treatment when the regulatory provisions at issue are ones issued to implement the substantive and procedural mandates of the Act.

Level of Deference

In a few cases, the Court has expressly considered the question of Chevron deference for such regulations. As noted previously, in Bragdon v. Abbott the Court declared that the regulations issued by the Department of Justice under Title III of the ADA should be accorded Chevron deference
