RICHARD DAHILL vs. POLICE DEPARTMENT OF BOSTON.

MARSHALL, C.J. This case is here on certification from the United States District Court for the District of Massachusetts, pursuant to S.J.C. Rule 1:03, as appearing in 382 Mass. 700 (1981). The question certified, which concerns the definition of the term "handicap" in the Massachusetts antidiscrimination statute, G. L. c. 151B, is as follows: "Whether Massachusetts

Page 234

General Laws c. 151B requires consideration of mitigating or corrective devices in determining whether a person has a handicap." [Note 1]

I

The relevant background is contained in the memorandum and order of the District Court judge in which he denied in pall and granted in part a motion for summary judgment of the police department of Boston. See S.J.C. Rule 1:03, s. 3 (2). We summarize only those facts that illuminate our resolution of the certified question.

Richard Dahill was born with a severe hearing impairment. At the age of three he began receiving medical care for his hearing loss and wearing hearing aids. He continued to receive medical care until the age of thirteen, when his hearing stabilized. Without the use of hearing aids, Dahill's hearing remains significantly impaired. With the use of hearing aids, his hearing is corrected to within normal limits. It is his use of hearing aids that raises the question we must answer.

Despite his severe hearing impairment, Dahill has achieved a wide range of academic and vocational success. His childhood medical records, which document extensive audiological evaluations and assessments, report above-average performance in school. He is a certified high school English teacher, and has worked as a lifeguard and health club worker. Dahill attended and has graduated from college and law school.

In 1996, he applied for a position as a Boston police officer. In February, 1997, he received a conditional offer of employment, subject to meeting the medical standards promulgated by the Commonwealth's human resources division. After conducting an auditory examination, the department's physician, Dr. Luther Arnold, determined that Dahill had a "Category B Condition," which does not automatically disqualify a person from

Page 235

employment as a police officer. [Note 2] Dr. Arnold certified that Dahill met the Commonwealth's hearing requirements with the use of his hearing aids. [Note 3]

Dahill subsequently entered the Boston Police Academy for a twenty-six week training program required of all new police officers. At the academy, several episodes occurred that raised concerns on the part of the department that Dahill's hearing might make him unfit to be a police officer. In one incident Dahill did not respond to an oral instruction to retrieve water bottles after a training run. On another occasion he did not respond to a radio call. He also did not hear a gunshot during a firearms training exercise. Dahill has offered explanations for these incidents, but they are not germane to the issue before us.

After receiving reports of the episodes, Dr. Arnold again evaluated Dahill's hearing, and sent Dahill to another specialist for auditory tests. [Note 4] On the basis of his examination, the specialist's report, and the instructors' reports of Dahill's training, Dr. Arnold sent a report to the police commissioner of Boston stating that "[t]here remains a major question [of] safety" regarding Dahill's ability to perform the duties of a police officer. The department then terminated Dahill, explaining to him that his "auditory deficiencies" rendered him "incapable of effectively and safely performing the essential duties of a Police Officer."

Dahill sued, claiming that his termination violated the Massachusetts antidiscrimination statute, G. L. c. 151B, s. 4; the

Page 236

Massachusetts equal rights statute, G. L. c. 93, s. 103; the Federal Rehabilitation Act, 29 U.S.C. s. 794 (2000), and the Americans with Disabilities Act (ADA), 29 U.S.C. s.s. 12101 et seq (2000).

We are asked to decide only whether a person who brings a claim pursuant to G. L. c. 151B, s. 4 (16), [Note 5] has a "handicap" as defined by G. L. c. 151B, s. 1 (17) [Note 6] if the person's impairment has been or can be alleviated by the use of corrective devices or other mitigating measures.

The department urges that we be guided by the decision of the United States Supreme Court in Sutton v. United Air Lines, Inc., 527 U.S. 471 (1999), where the Court concluded that, under the ADA, "if a person is taking measures to correct for, or mitigate, a physical or mental impairment, the effects of those measures - both positive and negative - must be taken into account when judging whether that person is 'substantially limited' in a major life activity and thus 'disabled.' " Id. at 482. The ADA defines "disability," [Note 7] in part, as: "a physical or mental impairment that substantially limits one or more of the major life activities of such individual." 42 U.S.C. s. 12102 (2).

Page 237

Because the definition of "handicap" contained in G. L. c. 151B, s. 1 (17) ("a physical or mental impairment which substantially limits one or more . . . major life activities"), is essentially identical, the department suggests that the interpretation of the Federal statute by the Supreme Court compels a similar reading of the Massachusetts statute. We must first ascertain what the Massachusetts Legislature intended in 1983 when it amended our antidiscrimination statute to prohibit unlawful employment discrimination of handicapped persons, G. L. c. 151B, s. 1 (17), s. 4 (16), inserted by St, 1983, c. 533, s.s. 2, 6, before we consider the Supreme Court's interpretation of a Federal statute enacted in 1990, seven years later. See Pub. L. 101-336, s. 2, 104 Stat. 328 (1990).

The language of the Massachusetts statute is not dispositive. Cf. Acting Superintendent of Bournewood Hosp. v. Baker, 431 Mass. 101, 104 (2000). The statute draws a distinction between persons who have a physical or mental impairment, and those whose impairment "substantially limits" a "major life" activity. G. L. c. 151B, s. 1 (17) (a). Only the latter are protected by the Massachusetts statute. But the statute is silent as to whether mitigating measures or corrective devices must be considered in determining whether a person with an impairment falls into the protected or nonprotected category. A person with a hearing impairment might experience no "substantial limit" of a "major life activity," even though he uses no corrective device: he would not be protected under the statute. A person with a hearing impairment might, even while using his corrective hearing aids, still suffer a "substantial limit," and thus would be protected. Finally, a person with a hearing impairment might experience a "substantial limit" of a "major life activity" when not using his hearing aids, but not experience any such "substantial limit" while the corrective devices were in use. The statute does not resolve whether this last person would be protected.

Because the language of the statute does not end our inquiry, we turn to other sources to discern the Legislature's intent. Acting Superintendent of Bournewood Hosp. v. Baker, supra at 104. The legislative history of G. L. c. 151B is instructive. In 1983, when the Legislature amended G. L. c. 151B to extend

Page 238

protection from unlawful employment discrimination to "handicapped" persons, St. 1983, c. 533, s. 2, the Legislature explicitly patterned the definition of "handicap" on the definition of "handicap" contained in a Federal statute enacted ten years earlier, the Federal Rehabilitation Act of 1973, 29 U.S.C. s. 706 (6) (2000). See Talbert Trading Co. v. Massachusetts Comm'n Against Discrimination, 37 Mass. App. Ct. 56, 60 (1994). [Note 8] At that time no court had determined, or, to our knowledge considered, whether "handicapped" referred to a person's impairment in its corrected or mitigated condition; corrective devices or other mitigating measures were simply not relevant. See, e.g., Strathie v. Department of Transp., 716 F.2d 227, 228-230 (3d Cir. 1983) (bus driver with controlled hearing impairment assumed to be "handicapped"); Davis v. Ohio Barge Line, Inc., 535 F. Supp. 1324, 1325 (W.D. Pa. 1982), vacated on other grounds, 697 F.2d 549 (3d Cir. 1983) ("controlled epileptic" assumed to be handicapped). We presume that in 1983 the Legislature was aware of the then-existing case law interpreting the Federal statute, and that it must have intended the term "handicap" in the Massachusetts statute to be interpreted in a manner that was consistent with the then-existing Federal jurisprudence. [Note 9] See Duarte v. Healy, 405 Mass. 43, 47 (1989) (Legislature presumed to be aware of United

Page 239

States Supreme Court case interpreting 42 U.S.C. s. 1983 when it patterned Civil Rights Act after s. 1983).

Guidance provided by the Massachusetts Commission Against Discrimination (MCAD) on this issue is also illuminating. In 1998, the MCAD issued guidelines that provide that "[t]he existence of an impairment is generally determined without regard to whether its effect can be mitigated by measures such as medication, auxiliary aids or prosthetic devices." Massachusetts Commission Against Discrimination Guidelines: Employment Discrimination on the Basis of Handicap Chapter 151B s. II.A.7 (1998). The guidelines explain that "an employee who is legally blind, but whose vision is correctable with glasses, may be considered 'handicapped' because his impairment substantially limits his ability to perform the major life activity of seeing." Id. The Legislature has delegated to the MCAD the authority to "formulate policies to effectuate the purposes" of G. L. c. 151B and to "adopt, promulgate, amend and rescind rules and regulations" to implement those policies. G. L. c. 151B, s. s. 2, 3 (5). The guidelines represent the MCAD's interpretation of G. L. c. 151B, and are entitled to substantial deference, even though they do not carry the force of law. See Berrios v. Department of Pub. Welfare, 411 Mass. 587, 595 (1992), quoting A. Cella, Administrative Law and Practice s. 747 (1986) (administrative agency "has considerable leeway in interpreting a statute it is charged with enforcing"); Bynes v. School Comm. of Boston, 411 Mass. 264, 269 (1991) (interpretations of G. L. c. 151B offered by MCAD are "entitled to substantial deference"); Rock v. Massachusetts Comm'n Against Discrimination, 384 Mass. 198, 206 (1981) (MCAD, not courts, has primary responsibility to determine scope of G. L. c. 151B). It is particularly appropriate to defer to the MCAD's interpretation where, as here, the legislative policy is

Page 240

"only broadly set out in the governing statute." Id. at 204, quoting School Comm. of Wellesley v. Labor Relations Comm'n, 376 Mass. 112, 116 (1978).

The public policies underlying G. L. c. 151B, s. 4 (16), are clear: to protect "handicapped individuals from deprivations based on prejudice, stereotypes, or unfounded fear, while giving appropriate weight to such legitimate concerns of [employers] as avoiding exposing others to significant health and safety risks." Cox v. New England Tel. & Tel. Co., 414 Mass. 375, 383-384 (1993), quoting School Bd. of Nassau County v. Arline, 480 U.S. 273, 287 (1987). An interpretation that the term "handicap" does not require consideration of corrective devices is consistent with that broad mandate. An alternative interpretation excludes from the statute's protection numerous persons who may mitigate serious physical or mental impairments to some degree, but who may nevertheless need reasonable accommodations to fulfil the essential functions of a job. [Note 10]

The Legislature has directed that the provisions of G. L. c. 151B "shall be construed liberally" for the accomplishment of the remedial purposes of the statute. G. L. c. 151B, s. 9. Surely one aspect of that remedial purpose is to encourage impaired persons to overcome or mitigate their disabilities. [Note 11] Advancements in medicine and the biological sciences, as well as rehabilitative technologies, now offer new hope to many individuals who previously may have been totally or significantly incapacitated by an impairment. The broad prohibition against the discrimination of qualified handicapped individuals contained in the 1980 amendment to the Massachusetts Constitu-

Page 241

tion [Note 12] and the enactment three years later of legislation extending protection in employment to handicapped persons are recognition that persons who are physically or mentally impaired are nevertheless capable of becoming productive and successful members of the workforce. We construe G. L. c. 151B, s. 4, to give the fullest effect to that recognition.

The department suggests that the interpretation we find persuasive is not compelled because a handicapped person, such as Dahill, who has availed himself of corrective measures may nevertheless seek protection from discrimination under the third prong of the definition of "handicap," as one who is "regarded as" having an "impairment that substantially limits one or more major life activities." The Legislature identified three avenues by which a person can establish that he falls within the statute's protection: the person (a) has an "impairment" that substantially limits a major life activity, (b) has a "record" of such impairment, or (c) is "regarded" as having such impairment. See note 6, supra. Loosely speaking, the first prong protects only those persons with actual physical of mental limitations, while the third prong protects those persons who, whether actually impaired or not, may be the victims of stereotypic assumptions, myths, and fears regarding such limitations. A plaintiff may prove that he is a handicapped person under one, two, or all of the three statutory definitions. [Note 13] The question we are asked to answer is whether our antidiscrimination statute requires

Page 242

"consideration of mitigating or corrective devices in determining whether a person has a handicap." It does not, regardless of whether a plaintiff can prevail under the first prong of the definition, as well as under the third.

We return to the holding of the Supreme Court in Sutton v. United Air Lines, Inc., 527 U.S. 471 (1999). There are sound reasons why our interpretation of the Massachusetts statute diverges from the Court's interpretation of similar language in the Federal statute. First, the Supreme Court attributed little weight to guidelines issued by the Equal Employment Opportunity Commission (EEOC) that "the determination of whether an individual is substantially limited in a major life activity [should] be made without regard to mitigating measures [under the ADA]" (emphasis added). Sutton v. United Air Lines, Inc., supra at 481, citing 29 C.F.R. Part. 1630, App. at 1630.2(j) (1998). Because Congress has not granted to the EEOC the authority to issue regulations interpreting or implementing the generally applicable provisions of the ADA, including the statutory definition of "disability," the Court said that it had no need to decide what deference the regulations were due. Sutton v. United Air Lines, Inc., supra at 479-480. [Note 14] In contrast, as we have explained, the General Court has expressly authorized the MCAD to interpret and implement the provisions of the Massachusetts antidiscrimination statute.

Second, in the preamble to the Federal legislation, Congress had estimated that forty-three million Americans have disabilities. See id. at 484-485. This number would have been far larger, the Supreme Court reasoned, if Congress had intended the ADA to cover people with "corrected physical limitations." See id. at 487. The Massachusetts statute, in contrast, contains no such estimate of the number of people in the Commonwealth

Page 243

with handicaps, nor does it contain any analogous provision suggesting that the Legislature intended to exclude from coverage the many persons with significant, but correctable, impairments. While Federal precedents can be "most helpful" in the resolution of cases involving G. L. c. 151B, Cox v. New England Tel. & Tel. Co., 414 Mass. 375, 384 (1993), because the Massachusetts nondiscrimination statute differs from the ADA in at least the two critical respects we have discussed, it is not appropriate to follow the Federal jurisprudence in this case. [Note 15]

We are not persuaded that our decision today will open the floodgates of litigation, as the department fears. Our interpretation of G. L. c. 151B, s. 1 (17), heralds no change in Massachusetts jurisprudence: since 1983, when the Legislature made the relevant amendment to G. L. c. 151B, judges and litigants in Massachusetts have assumed that a person with a significant physical or mental impairment met the threshold definition of "handicap," whether the person used corrective devices or took other mitigating measures. See, e.g., Labonte v. Hutchins & Wheeler, 424 Mass. 813 (1997) (no discussion of mitigation); Wooster v. Abdow Corp., 46 Mass. App. Ct. 665, 667 (1999) (controlled asthma); Handrahan v. Red Roof Inns, Inc., 43 Mass. App. Ct. 13, 15-16 (1997) (controlled epilepsy).

Additionally, the determination whether Dahill has a "handicap" is a threshold inquiry under G. L. c. 151B: does he fall within the class of persons the Legislature sought to protect? If he meets that threshold test, he must still prove that he can perform the essential functions of a police officer, with or without reasonable accommodations. See Cox v. New England Tel. & Tel. Co., supra at 383. Reasonable accommodation by the department to his handicap need only be made if it would impose no "undue hardship" on the employer. G. L. c. 151B, s. 4 (16). Dahill must also demonstrate that his handicap was the cause of the department's allegedly unlawful discrimination. See Labonte v. Hutchins & Wheeler, supra at 821. These legislative criteria constrain any possibility that recovery for Dahill

Page 244

will be automatic. [Note 16] See Arnold v. United Parcel Serv., Inc., 136 F.3d 854, 861 (1st Cir. 1998) (under analogous Federal provisions, even with earlier "broad view" of disability, concerns and interests of employers are still "amply protected").

We answer the certified question, "No."
