Pennsylvania Manufacturers Association v. William Cree, et al.
No. 730, September Term 2022. Opinion by McDonald, J.

Workers’ Compensation Act – Occupational Disease – Last Injurious Exposure Rule.
The Maryland Workers’ Compensation Act provides compensation to workers and their
dependents for a worker’s death or disability from an occupational disease contracted as a
result of and during the course of employment. If the worker contracted the disease as a
result of hazardous exposures while employed at more than one employer, a bright-line
rule in the statute assigns that liability to the last employer chronologically – and, if that
employer was insured by more than one insurer during that time, to the last insurer
chronologically of that employer – during the period of hazardous exposure. That
provision is known as the last injurious exposure rule.

Workers’ Compensation Act – Occupational Disease – Occupational Hearing Loss –
Applicability of Last Injurious Exposure Rule. While certain provisions of the
Maryland Workers’ Compensation Act, including the last injurious exposure rule, apply
generally to occupational disease claims, the Act treats claims of occupational hearing loss
differently in certain respects. In particular, when a claimant was exposed to harmful noise
while working for more than one employer, liability may be apportioned among those
employers either in equal shares or based on the amount of the worker’s exposure at each
employer. However, the statute is silent as to how liability is assigned among insurers, if
any of those employers was insured by more than one insurer during the period of
hazardous exposure. In the absence of specific direction in the statute, the same method of
allocation of liability should be applied to insurers as to the employers that they insure.

Gregory Hilton, Clerk
       The Maryland Workers’ Compensation Act (“Act”) provides benefits to employees

who suffer disability or death from an occupational disease – a disease contracted as a

result of and during the course of employment. An occupational disease may result from

exposure to workplace hazards over a period of time. That period may encompass the

individual’s employment with more than one employer and, even if there is only one

employer, that employer may have obtained workers’ compensation insurance from

different insurers over that period. The General Assembly has provided a bright-line

general rule in the statute that assigns liability for an occupational disease claim entirely to

the employer and insurer that are last in chronological order during the relevant period.

This provision is known as the “last injurious exposure rule” – an all-or-nothing rule that

furthers the efficient processing of claims because it dispenses with any need to allocate

liability based on causation.

        Hearing loss attributable to exposure to noise in the workplace may be compensable

as an occupational disease under the Act, but is subject to certain specific rules. Among

the provisions specific to occupational hearing loss, the Act provides that, when there are

multiple employers over the period of the employee’s exposure to harmful noise in the

workplace, liability may be apportioned among those employers either in equal shares or

in some other manner warranted by the evidence. Thus, the last injurious exposure rule

does not apply. The statute is silent on the allocation of liability among the insurers of

those employers.
       This case presents the question whether the last injurious exposure rule applies,

solely as to the apportionment of liability among an employer’s insurers, when a workers’

compensation claim is based on occupational hearing loss.

       For the reasons set forth in this opinion, we hold that it does not.

                                              I

                                        Background

A.     Legal Landscape

       1.     Workers Compensation Act – Generally

       Benefits and Insurance

       The Maryland Workers’ Compensation Act provides compensation for death or

disability suffered by an individual as a result of an accidental injury or an occupational

disease related to the individual’s employment. Maryland Code, Labor & Employment

Article (“LE”) §9-101 et seq. The Act requires employers, including governmental entities,

to provide workers’ compensation benefits, either by maintaining insurance with an

authorized insurer or by self-insuring in accordance with the statute. LE §9-402(b).

       Uninsured Employers’ Fund

       On occasion, an employer fails to comply with its statutory obligation to obtain

insurance or to self-insure. The liability of an uninsured employer, or of a self-insured

employer that becomes insolvent, may be assigned to the Uninsured Employers’ Fund

(“UEF”), a State entity created for that purpose. LE §§9-405(g), 9-1002; LE §10-301 et

seq.

                                              2
       Last Injurious Exposure Rule

       In many cases involving occupational diseases, the disease may be the result of

hazardous exposures that occurred during the claimant’s employment with more than one

employer. In that situation, liability for a workers’ compensation claim is allocated by

statute according to what is known as the “last injurious exposure rule.” Under that rule,

the entire liability for the occupational disease is assigned to the last of those employers

chronologically and, in turn, to that employer’s last insurer chronologically. LE §9-502(b).

No liability is apportioned to prior employers or insurers. This provides the Workers’

Compensation Commission (“Commission”) with an arbitrary bright-line rule that is

simpler to administer than attempting to apportion liability among employers or insurers

and that eliminates disputes over relative causation. See Lowery v. McCormick Asbestos

Co., 300 Md. 28, 48 (1984).

       2.     Benefits and Liability for Occupational Hearing Loss

       In provisions separate from those that generally concern accidental injuries and

occupational diseases, the Act provides that, in some circumstances, a loss of hearing due

to exposure to harmful noise at the workplace – sometimes referred to in the statute as

“occupational deafness” or “occupational hearing loss” – is compensable under the Act. 1

LE §9-505; see Green v. Carr Lowery Glass Co., 398 Md. 512, 516-18 (2007). The Act

includes special provisions concerning the measurement of hearing loss and the extent and

       1
        A claim of occupational hearing loss may result from either an accidental injury
or an occupational disease. Yox v. Tru-Rol Co., 380 Md. 326, 332 (2004).
                                             3
allocation of liability related to such a claim. LE §9-505, §9-649 et seq.; see generally

Montgomery County v. Cochran, 471 Md. 186, 194-95, 211-17 (2020).

       At issue in this case are special provisions concerning the extent and allocation of

liability for occupational hearing loss claims. Under those provisions, the claimant must

have worked for the employer in a job that exposed the claimant to harmful noise for at

least 90 days. LE §9-505(b). If so, the employer is liable for the “full extent” of the

claimant’s occupational hearing loss. LE §9-651(a). However, the employer’s liability

may be limited if the employer can establish “by competent evidence” the extent of the

claimant’s hearing deficit prior to the claimant’s exposure to harmful noise at the

employer’s workplace. LE §9-651(b). Moreover, an employer may implead into the

workers’ compensation proceeding “any other employer in whose employment the

employee was exposed to harmful noise.” LE §9-652(a). If the Commission finds that an

impleaded employer would also be liable to the employee, the employer against whom the

claim was filed may obtain contribution from the impleaded employer. LE §9-652(c).

Liability is then allocated among the employers by a bright-line rule – equal shares – or

otherwise if “the evidence warrants a different apportionment.” Id.

       Thus, unlike the treatment of claims involving other occupational diseases, liability

in occupational hearing loss cases is allocated among employers in accordance with a

determination of causation, or a bright-line rule quite different from that of the last injurious

exposure rule. At least that is the case with respect to employer liability; the occupational

hearing loss provisions do not explicitly refer to insurers.

                                               4
B.     Factual and Procedural Background

       1.       Work History and Hearing Loss Diagnosis

       Appellee William Cree worked as a police officer for almost 25 years. 2 His career

spanned police departments in three Maryland jurisdictions: (1) the Town of Riverdale 3

(“the Town”) during 1971 to 1974; (2) the City of Laurel (“the City”) during 1974 to 1980;

and (3) Prince George’s County (“the County”) during 1980 to 1995. The City is an

Appellee in this appeal.

       On August 31, 2018, an audiologist evaluated Mr. Cree’s hearing and determined

that his hearing had deteriorated to the extent that it met the criteria for compensation under

LE §9-650 of the Act.

       2.       The Claim

       On February 6, 2019, Mr. Cree filed a claim with the Commission against the

County, alleging binaural hearing loss 4 with a date of disablement of August 31, 2018.

The County contested the claim. In addition, the County impleaded both of Mr. Cree’s

       2
         Although Mr. Cree is the first-named Appellee in this appeal, he did not file a brief
or otherwise participate in the appeal. Presumably that is because the issue on appeal does
not concern the merits of his claim or the amount of compensation, but rather the allocation
of part of that liability to an insurer of one of his past employers.
       3
           The Town changed its official name to “Riverdale Park” in 1998.
       4
         “Binaural” means relating to both ears. See, e.g., Merriam-Webster.com
Dictionary, Merriam-Webster, https://www.merriam-webster.com/dictionary/binaural.
(last accessed July 24, 2023). Binaural hearing loss is calculated by measuring an
individual’s hearing ability in each ear and applying a statutory formula. See LE §9-650(d).
                                              5
prior police department employers – the Town and the City, which is one of the Appellees

in this appeal.

         The City in turn impleaded Appellant Pennsylvania Manufacturers Association

(“PMA”), which had insured the City during roughly half of the period that Mr. Cree had

worked in the City’s police department during the 1970s. 5 Because the City was unable to

determine how it had been insured during the rest of that period, the City was considered

to be uninsured during that time. Appellee UEF was therefore impleaded as an additional

party.

         3.       Proceedings before the Commission

         On April 30, 2021, the Commission held a remote hearing concerning issues related

to Mr. Cree’s claim. In addition to Mr. Cree, all three employers (the Town, the City, and

the County) and various insurers participated in the hearing.

         Among the issues raised by the parties was whether PMA should be considered the

City’s insurer during Mr. Cree’s employment with its police department. 6 Pertinent to that

issue, Mr. Cree testified that his exposure to industrial noise while employed by the City’s

police department was consistent over the six years that he worked there – including the

period after the PMA policy expired. PMA argued that it would not be considered the last

         5
             PMA insured the City during the period from August 12, 1976 to July 28, 1979.
         6
          The Commission conducted other proceedings and resolved other issues
concerning Mr. Cree’s claim. There is no need to describe those in detail for purposes of
this opinion.
                                               6
insurer chronologically of the City and should therefore be relieved of any liability under

the last injurious exposure rule.

       On June 7, 2021, the Commission issued an order in which it found that Mr. Cree

had sustained a disability in the form of binaural hearing loss as a result of an occupational

disease, with a date of disablement of August 31, 2018. Pertinent to this appeal, the

Commission also held that the last injurious exposure rule under LE §9-502(b) did not

apply to Mr. Cree’s claim. Instead, in accordance with the statute concerning occupational

hearing loss, the Commission apportioned liability for the claim among the three police

departments that had employed him during the period of exposure to industrial noise. In

particular, with respect to the City, it found that the City was responsible for 25% of the

claim and further found that PMA was liable as it had insured the City during the period of

Mr. Cree’s exposure to industrial noise. 7

       4.     Judicial Review

       PMA initiated an on-the-record appeal in the Circuit Court for Prince George’s

County. The sole issue raised by PMA was whether the last injurious exposure rule should

be applied to eliminate any liability of PMA. 8 The Circuit Court heard oral argument

       7
         The Commission found that the County was liable for 63% of Mr. Cree’s claim
and that the Town was liable for 12% of the claim. That allocation corresponds to the
approximate percentage of his police career that Mr. Cree spent with each jurisdiction. The
allocation of liability among the three employers is not at issue in this appeal.
       8
          PMA has not asserted that it is liable for only a proportionate share of the City’s
liability; rather, it argued that it should have no liability at all with respect to Mr. Cree’s
claim.
        The Town raised a separate issue in a cross-petition for judicial review. The Circuit
Court’s resolution of that issue is not at issue in this appeal.
                                              7
during April 2022. On May 2, 2022, the court affirmed the Commission’s decision in an

oral opinion, which the court later incorporated in a written order.

       PMA filed a timely notice of appeal to this Court. The Town and UEF have

appeared in opposition and filed briefs as Appellees.

                                              II

                                         Discussion

       As outlined earlier, in a typical workers’ compensation claim based on an

occupational disease, the “last injurious exposure rule” assigns liability for the claim solely

to the employer who last employed the claimant during the period of exposure to workplace

hazards that resulted in that disease. However, that rule does not apply when the claim is

based on occupational hearing loss; instead, liability may be assigned in full to any

employer where the claimant’s exposure to hazardous noise met a statutory threshold or

may be allocated in part to each employer for which the claimant worked during the period

of exposure to hazardous noise.

       In this appeal, it is undisputed that, in light of Mr. Cree’s testimony that he was

consistently exposed to industrial noise during his career as a police officer, each of his

three police employers – the Town, the City, and the County – may be allocated a portion

of the liability on his claim.

       The sole issue raised by PMA is whether, in the context of an occupational hearing

loss claim, the “last injurious exposure rule” governs whether an insurer is liable for a

claim against an insured employer when the employer had more than one insurer during

the period of the claimant’s exposure to hazardous noise. If that rule governs an insurer’s

                                              8
liability, PMA would not be liable because its policy covering the City terminated before

Mr. Cree experienced his last injurious exposure during his tenure with the City. If the rule

does not apply, PMA is liable.

A.     Standard of Review

       The issue raised by PMA is a question of law. In a workers’ compensation case, an

appellate court reviews a determination of a question of law de novo, without deference to

the decision of the Commission or the decision of a circuit court. Long v. Injured Workers’

Ins. Fund, 225 Md. App. 48, 57 (2015).

B.     Whether the Last Injurious Exposure Rule Applies to Hearing Loss Claims

       The question whether the last injurious exposure rule applies is an issue of statutory

construction. The method for resolving such a question is well established. “The goal of

statutory interpretation is to ascertain and effectuate the real and actual intent of the

Legislature. One begins with the text of the statute and the statutory scheme of which it is

part. An examination of the legislative history helps to confirm conclusions drawn from

the text or to resolve ambiguities. [C]onsideration is given to the consequences of

alternative interpretations of the statute in order to avoid constructions that are absurd or

unreasonable and to ground the court’s interpretation in reality.” Westfield Ins. Co. v.

Gilliam, 477 Md. 346, 370 (2022) (internal quotation marks and citations omitted). Prior

case law concerning the statute may also be informative. Aleman v. State, 469 Md. 397,

421 (2020). Finally, because the Act is a remedial statute, “it must be construed as liberally

in favor of injured employees as its provisions will permit in order to effectuate its

                                              9
benevolent purposes.” Reger v. Washington Co. Board of Education, 455 Md. 68, 96

(2017); see also LE §9-102 (stating principles of construction for the Act).

       The first task, then, is to examine the statutory text.

       1.     Statutory Text

       The issue in this appeal requires an analysis of the relationship between the statutory

provisions that establish general rules regarding occupational disease claims – in particular,

those set forth in LE §9-502 – and those provisions that specifically govern claims of

occupational hearing loss – which are set forth in LE §9-505 and §9-649 through §9-652.

       LE §9-502(b)

       As the heading of Subtitle 5 of the Act indicates, that subtitle provides general rules

concerning the entitlement to, and liability for, compensation under the statute. 9 Certain

general rules concerning claims based on occupational diseases are set forth in LE §9-502.

The obligation of an employer (and the employer’s insurer) to provide compensation for

disability or death caused by an occupational disease is set forth in subsection (c) of LE

§9-502. Subsection (b) of the statute in turn states another general rule – that the obligation

to provide compensation is subject to the last injurious exposure rule:

       9
         That heading is “Entitlement to and Liability for Compensation.” While many
headings in the Maryland Annotated Code were originally devised by legal publishers, this
particular heading was enacted by the General Assembly and thus is part of the law. See
Chapter 8, §2, Laws of Maryland 1991 at p. 845; cf. Maryland Code, General Provisions
Article, §1-208 (providing that the captions or catchlines that may appear in sections or
subsections of the code are not to be considered as titles, “[u]nless otherwise provided by
law”).
                                              10
       Subsection (c) of this section applies only to:

       (1)    the employer in whose employment the covered employee was last
              injuriously exposed to the hazards of the occupational disease; and

       (2)    the insurer liable for the risk when the covered employee, while
              employed by the employer, was last injuriously exposed to the hazards
              of the occupational disease.

LE §9-502(b). Critically, however, subsection (c), and perforce subsection (b) stating the

last injurious exposure rule, is qualified by the phrase “except as otherwise provided.” This

proviso indicates that there are exceptions to these general rules.

       Occupational Hearing Loss Provisions

       As indicated earlier, among the more extensive exceptions to the general rules on

occupational diseases are a number of provisions concerning occupational hearing loss.

For example, LE §9-505 sets specific threshold requirements for compensation for

occupational hearing loss. 10 Moreover, a completely separate part of the statute – Part VII

of Subtitle 6 of the statute – states certain rules peculiar to work-related claims of hearing

loss. See LE §9-649 through §9-652. 11 Those provisions allow for the imposition of

liability, to the “full extent” of the claim, on any employer for which the threshold

       10
           In particular, hearing loss is compensable if suffered with respect to frequencies
of 500, 1,000, 2,000, and 3,000 hertz. LE §9-505(a); see also LE §9-650. (“Hertz” is a
measure of sound frequency, perceived by the ear as the pitch of the sound.) The claimant
must have been exposed to harmful noise for at least 90 days during the claimant’s
employment with the employer. LE §9-505(b). The claimant must also meet the additional
criteria in LE §9-650 to have a compensable claim. See Green v. Carr Lowery Glass Co.,
398 Md. 512, 525-26 (2007).
       11
         As enacted by the General Assembly, Subtitle 6 of the Act is entitled “Benefits”
and Part VII of that subtitle is entitled “Occupational Deafness.”
                                             11
requirements are met – not just the last employer chronologically. Those provisions also

create a process for an employer that receives such a claim to implead other employers of

the claimant and for the allocation of liability among those employers equally or as

otherwise warranted by the evidence – for example, evidence that permits a determination

of causation. 12 The hearing loss provisions obviously conflict with the last injurious

      12
           The relevant provisions read as follows:

      §9-651. Extent of liability

               (a) In general. Except as provided in subsection (b) of this section,
      an employer is liable for the full extent of the occupational deafness of a
      covered employee if:
               (1) the employment of the covered employee by the employer has
      contributed to any extent to the occupational deafness of the covered
      employee; and
               (2) the employer otherwise is liable under this section and §9-505 of
      this title.

             (b) Limitation on liability. An employer is liable only for the part of
      the deafness attributable to the employment by the employer if the employer
      establishes by competent evidence, including the results of a professionally
      controlled hearing test, the extent of the deafness of the covered employee
      that existed before exposure to harmful noise in the employment of the
      employer.

      § 9-652. Impleader

             (a) Right of employer. In a proceeding for compensation on the claim
      of a covered employee, an employer who is liable for the full extent of the
      occupational deafness of the covered employee may implead any other
      employer in whose employment the covered employee was exposed to
      harmful noise.

             (b) Notice of impleader. To implead another employer, the employer
      shall give to the impleaded employer and to the Commission notice on the
      form that the Commission requires.

                                             12
exposure rule and therefore prevail over that rule under the “except as otherwise provided”

proviso in LE §9-502(c). However, in discussing the party liable to provide benefits for a

claim for occupational hearing loss, the provisions specific to that disease use the term

“employer”; the term “insurer” does not appear in them.

       Textual Analysis

       PMA asserts that the “plain language” of the statute unambiguously requires

application of the last injurious exposure rule to insurers in occupational hearing loss cases

– and therefore requires reversal of the Commission decision with respect to PMA in this

case. PMA’s position has two prongs. First, PMA argues that the absence of the word

“insurer” in LE §§9-651 and 9-652 of the occupational hearing loss provisions means that

those apportionment and procedural provisions do not apply to insurers. Second, PMA’s

position is premised on the notion that the tabulation of the last injurious exposure rule in

two paragraphs of LE §9-502(b) – one concerning employers (paragraph (1)) and one

concerning insurers (paragraph (2)) – means that the last injurious exposure rule applies

independently to insurers even when it does not apply to the employers that they insure.

              (c) Liability of impleaded employer

                     (1) If the Commission finds that the impleaded employer
              would have been liable to the employee had the employee proceeded
              against the impleaded employer under the claim being adjudicated,
              the employer liable to the employee is entitled to an award that:
                            (i) is against the impleaded employer; and
                            (ii) may be enforced in the same manner as an award in
              favor of a covered employee.
                     (2) Unless the evidence warrants a different apportionment, the
              impleaded employer and the employer liable to the covered employee
              shall have equal liability to the employee.
                                             13
       Regarding PMA’s first argument, does the absence of the word “insurer” in the

provisions concerning liability for occupational hearing loss mean that, while liability for

such a claim is allocated among multiple employers equally or on the basis of causation,

any liability of insurers is still governed by the last injurious exposure rule?          Not

necessarily. A review of the entire Act reveals that, while it frequently refers to the

obligation of an “employer or its insurer” to pay compensation, 13 it also often describes the

liability to pay compensation solely with reference to an “employer” without mentioning

an insurer. 14 In other instances, liability and the obligation to pay compensation are stated

in the passive voice with no specific reference to an “employer” or an “insurer.” 15

Nevertheless, as a general rule, an award against an employer under the Act is also binding

on the employer’s insurer.       See Maryland Code, Insurance Article, §19-402(b)(5)

(requiring workers’ compensation insurance policies to contain a provision requiring the

insurer to cover the employer’s liability for workers’ compensation claims). Given the

       13
          See, e.g., LE §9-605 (“If an employer or its insurer … pays compensation…”);
LE §9-615(b) (“The employer or its insurer shall pay the weekly compensation …”); LE
§9-621(b) (“The employer or its insurer shall pay …”); LE §9-627(a) (“… the employer or
its insurer shall pay …”); LE §9-660(b) (“The employer or its insurer shall provide …”);
LE §9-667 (“… the employer or its insurer shall reimburse …”).
       14
           See, e.g., LE §9-501(a) (“… each employer of a covered employee shall provide
compensation …”); LE §9-504(a) (“… an employer shall provide compensation …”); LE
§9-505(a) (“… an employer shall provide compensation …”); LE §9-509(a) (“… the
liability of an employer under this title is exclusive.”); LE §9-651(a) (“… an employer is
liable …”).
       15
         See, e.g., LE §9-635 (A covered employee … shall be paid compensation …”);
LE §9-643 (“A covered employee … shall be paid compensation …”); LE §9-683(d)(1)
(“Death benefits shall be paid to 1 or more of the dependents …”).
                                             14
general requirement in the Act that an employer obtain insurance or satisfy the

requirements to self-insure, the absence of the word “insurer” in many of these provisions

does not necessarily mean that an insurer is beyond their purview. 16

       The word “insurer” does not appear at all in any of the provisions that specifically

address liability for claims of occupational hearing loss; all speak only in terms of liability

of the claimant’s employer(s). See LE §§9-505, 9-649, 9-650, 9-651 & 9-652. But that

does not mean that an employer’s insurer is somehow exempt from liability for an

occupational hearing loss claim. For example, the fact that LE §9-505 states that “an

employer shall provide compensation to a covered employee for loss of hearing by the

covered employee …,” but makes no reference to an insurer, does not mean that the

employer’s insurer is absolved from liability for such a claim.

       As to PMA’s second argument drawn from statutory text – that the format of the

two paragraphs of LE §9-502(b) necessarily means that they operate independently of one

another – the statutory language does not explicitly endorse that interpretation. That

argument, too, is inconclusive at best.

       In short, a textual analysis alone does not unambiguously yield the conclusion urged

by PMA. We next turn to the legislative history of the Act for any indication that the

       16
         Without specifically analyzing the question, a treatise on Maryland workers’
compensation law appears to assume that the allocation and procedural provisions of LE
§§9-651 and 9-652 apply to insurers as well as the employers that they insure. See Clifford
B. Sobin, 1 Maryland Workers’ Compensation §9.4 (Oct. 2022 update) (referring to those
provisions as applying to “employer/insurers’ liability”).

                                              15
General Assembly intended to apply the last injurious exposure rule independently to

insurers in a situation where that rule does not apply to employers.

       2.     Legislative history

       Now more than a century old, the Maryland Workers’ Compensation Act has a long

lineage. The key provisions at issue in this case were first enacted before the General

Assembly began preserving legislative bill files in 1975. Nonetheless, it is useful to review

the development of the provisions governing occupational hearing loss in the context of

the Act as a whole. 17

       1914 – Act applies to accidental injuries in the workplace

       As originally enacted in 1914, the Maryland Workers’ Compensation Act provided

compensation for accidental injuries that arose out of and in the course of employment.

Chapter 800, Laws of Maryland 1914. The Act created a no-fault system to provide

employees who experienced work-related accidental injuries “with a certain, efficient, and

dignified form of compensation” without regard to fault in lieu of certain common law

remedies that would otherwise be available to injured workers. Polomski v. Mayor & City

Council, 344 Md. 70, 76-79 (1996) (describing the history of the statute).

       1939 – Act extended to occupational diseases with a last injurious exposure rule

       In 1939, the statute was amended to also provide compensation for injuries arising

from 34 listed occupational diseases in addition to accidental injuries. Chapter 465, Laws

       17
         An excellent summary of the history of the hearing loss provisions of the statute
appears in Yox v. Tru-Rol Co., 380 Md. 326, 330-36 (2004) (Wilner, J.).
                                             16
of Maryland 1939, codified at Maryland Code (1924), Article 101, §§32A through 32J. 18

Occupational hearing loss was not among the listed diseases. 19 See id., Article 101, §32A.

       Claims based solely on occupational diseases potentially presented a new question

concerning the allocation of liability under the Act. While an accidental injury generally

would occur on a particular date while the claimant was working for a particular employer

that presumably was insured by a particular insurer on that date, an occupational disease

could result from the individual’s exposure to hazards over a period of time during which

the individual had various employers. Even if the claimant’s injurious exposure occurred

over time at only one employer’s workplace, that employer may have insured the risk with

different insurers for different parts of that period. This raised the question as to how to

allocate responsibility for providing compensation among employers and the insurers of

those employers.

       In the 1939 amendments, the Legislature chose to adopt a “last injurious exposure

rule” to eliminate any need to parse out relative fault among all of those potential parties.

As one commentator observed at that time, in avoiding the need to litigate the extent to

       18
         Shortly after enactment of these provisions, the 1939 compilation of the Maryland
Code recodified the occupational disease provisions as Article 101, §§34 through 43. Like
other such code revisions between 1888 and the early 1970s, the 1939 code compilation of
Maryland statutes was accomplished by private editors and a legal publisher. (In contrast,
the 1888 code and the most recent code revision that began in the early 1970s were
accomplished by legislative enactments of the General Assembly.) See Alan M. Wilner,
Blame It All On Nero: Code Creation and Revision in Maryland (February 14, 1984),
available at https://perma.cc/ZS6G-RB8J.
       19
          As indicated earlier, hearing loss was compensable if it resulted from a traumatic
injury and was therefore part of an accidental personal injury. See footnote 1 above; see
also, e.g., Maryland Code (1924), Article 101, §36(3).
                                             17
which each employer should be held responsible for an occupational disease, the last

injurious exposure rule was “very practical, although undoubtedly some injustice must be

done in its application.” J. Nicholas Shriver, Jr., The Maryland Occupational Disease Law,

4 Md. L. Rev. 133, 143 (1940). The theory appears to be that, although that rule assigns

liability somewhat arbitrarily, an employer held liable in one case may escape liability in

the next and things will average out over the long run while eliminating a need to ascertain

causation in every case. See Lowery v. McCormick Asbestos Co., 300 Md. 28, 39 (1984)

(“The operation of the rule … provides certainty in a way which is somewhat arbitrary. …

It is fair to employers only if it is applied consistently so that liability is spread

proportionately among employers by operation of the law of averages.”) (internal quotation

marks and citation omitted).

       The 1939 amendments of the Act concerning occupational diseases included the last

injurious exposure rule in the following language:

              Where compensation is payable for an occupational disease, the
       employer in whose employment the employee was last injuriously exposed
       to the hazards of such disease, and the insurance carrier, if any, on the risk
       when such employee was last so exposed under such employer, shall be liable
       therefor; …

Chapter 465, Laws of Maryland 1939, as codified in the 1924 version of the Maryland

Code, Article 101, §32C. It was later recodified, in essentially identical language, as

Article 101, §23(b) in the 1957 version of the Maryland Code. 20 The language and

       20
         In the interim, the provision was recodified several times without any change in
language as §36, and later §23, of the 1939 version of Article 101 of the Maryland Code,
and as §22(b) of Article 101 of the 1951 version of the Maryland Code. In the 1957 version
                                            18
codification of the last injurious exposure rule then remained unchanged until the early

1990s. 21

       As is evident from the language of this provision, it created a two-step analysis to

establish a single payor of the liability on a claim: first, determine the “last employer”

during the period of the claimant’s exposure to the hazardous conditions; second, once the

last employer has been identified, determine the last insurer “if any” on the risk during the

claimant’s exposure with the last employer. The end result was that there would be only

one payor of liability for a typical occupational disease claim – either the “last employer”

if self-insured or the “last insurer” of that employer if not self-insured. The last injurious

exposure rule thus came into play as to insurers only after a determination that the last

employer was not self-insured.

       1951 – Occupational disease includes occupational hearing loss

       As noted above, the 1939 amendments adding occupational diseases to the Act listed

specific occupational diseases, but that list did not include occupational hearing loss. In

1951, the Legislature amended the statute to delete the limitation to a specific list of

of the code, the introductory word “where” in §23(b) was replaced by “when,” presumably
because the last injurious exposure rule relates to chronology rather than location.
       21
          In 1980, as part of a bill making substantive changes in other provisions of the
law, the word “such” in §23(b) was replaced in the four instances in which it appeared in
that provision with the word “the.” Chapter 706, Laws of Maryland 1980. This appears to
have been a minor stylistic change, as the same substitution was made throughout the bill
in many instances in which the word “such” appeared. Presumably, this was because
modern standards for legislative drafting discourage the use of “such” as a demonstrative
adjective. See Maryland Style Manual for Statutory Law (2008) at 80; see also Bryan A.
Garner, The Redbook: A Manual on Legal Style (3d ed. 2013) at 223 (recommending the
substitution of “the,” “this,” or “that” in place of “such” as an adjective).
                                             19
covered ailments.     The Act was thus extended to all diseases, thereby including

occupational hearing loss. Chapter 287, Laws of Maryland 1951; see Yox, 380 Md. at 332.

       1961 – Case law limits liability for occupational hearing loss

       Subsequent to the 1951 amendment, the Court of Appeals of Maryland, now known

as the Supreme Court of Maryland, held that occupational hearing loss was compensable

as an occupational disease only if the claimant was incapacitated by the disease and unable

to perform the regular work for which the claimant was employed. Belschner v. Anchor

Post, 227 Md. 89, 93 (1961). That holding was based on the definition of “disablement”

in the Act’s provisions concerning occupational diseases. 227 Md. at 93. The Court invited

the General Assembly to overturn that holding and liberalize the law with respect to

occupational hearing loss, if it wished to do so. Id. at 95.

       1967 – Special provisions concerning occupational hearing loss added to Act

       A few years later, the General Assembly did liberalize the law. In 1967, at the

recommendation of a gubernatorial commission, the General Assembly enacted special

provisions relating to occupational hearing loss. Chapter 155, Laws of Maryland 1967; see

Seventh Report of the Governor’s Commission to Study Maryland Workmen’s

Compensation Laws at p. 2, recommendation 4 (February 14, 1967). A key purpose of that

legislation was to overturn the holding in Belschner and to allow a worker to obtain benefits

for occupational hearing loss, even if the worker could still perform the worker’s job. See

Yox, 380 Md. at 333-35; Crawley v. General Motors Corp., 70 Md. App. 100, 102-08, cert.

denied, 310 Md. 147 (1987). The legislation included specific criteria for measuring

hearing loss and a specification as to when such hearing loss was compensable. See

                                             20
Maryland Code (1957), Article 101, §25A(a)-(f), (i)-(j), now codified in LE §§ 9-505, 9-

650.

       Pertinent to this appeal, the 1967 legislation also added other provisions specific to

occupational hearing loss, including the substantive and procedural provisions for the

allocation of liability when the claimant was exposed to harmful industrial noise while

employed by more than one employer. See Maryland Code (1957), Article 101, §25A(h),

now codified in LE §§9-651, 9-652. As the title to the 1967 bill indicated, the purpose of

the amendments was, among other things, “to provide workmen’s compensation benefits

for occupational deafness due to industrial noise” and “to allocate liability for such

occupational deafness among employers.”

       The liability allocation provisions were apparently based on the fact that

occupational hearing loss presents a situation where causation may be more readily

determined than is the case with other occupational diseases. See Annotation, Workers’

compensation: liability of successive employers for disease or condition allegedly

attributable to successive employments, 34 ALR4th 958 (1984 & Cum. Supp.), §2(a)

(“[T]he main theoretical basis for [the last injurious exposure rule] – that the precise degree

of contribution by each employer to the final disability must be conjectural – is defeated

by the rare circumstance where the precise degree of such contribution by each employer

may indeed be measured, such as where a series of hearing tests has been administered to

one suffering hearing loss in a series of employments …”); see also Clifford B. Sobin, 1

Maryland Workers’ Compensation §9.1 (Oct. 2022 update), n.11 (noting that, in many

                                              21
instances where there is exposure to harmful noise in a workplace, the employer will

require that employees take periodic hearing tests).

       The 1967 legislation replaced the bright-line last injurious exposure rule as to

employers with a regime that incorporates an opportunity to allocate liability based on

evidence and, in the absence of such evidence, a different bright-line default rule (equal

shares) for the allocation of liability. As a threshold requirement, the claimant must have

been exposed to harmful noise while employed with an employer for at least 90 days for

the employer to be liable. Maryland Code (1957), Article 101, §25A(j). If so, that

employer could be held liable for the entire claim, but could limit its liability if it was able

to show “by competent evidence” that the employee’s hearing was already impaired at

outset of exposure during that employment. Id., §25A(h). Even if that employer was liable

for the full extent of hearing loss, it could implead other employers in whose employment

the claimant was exposed to harmful noise and essentially obtain contribution.               Id.

Liability was to be shared equally unless the “evidence warrants a different

apportionment.” Id.

       Thus, in contrast to the provisions governing other occupational diseases, the 1967

amendments concerning occupational hearing loss established: (1) a threshold period of

claimant exposure for an employer to be liable; (2) full liability for any employer for whom

that threshold is met – not just the last employer; (3) if a liable employer can prove that the

claimant’s hearing was already impaired before employment, partial liability; (4) the

availability to a liable employer of contribution from other liable employers; and (5)

                                              22
allocation of liability among multiple liable employers in equal shares or differently, if

evidence supports a different apportionment.

       This was a very different approach from the bright-line last injurious exposure rule,

which places responsibility for the entire liability on a specific employer and in turn a

specific insurer of that employer, does not provide for apportionment in any manner, and

does not contemplate any determination of relative causation.

       1991 – Recodification in the new Labor & Employment Article

       In 1991, as part of the code revision bill that created the Labor & Employment

Article, the last injurious exposure rule was codified in its current language as LE §9-

502(b). Chapter 8, §2, Laws of Maryland 1991, at pp. 846-47. In its new codification, the

last injurious exposure rule was tabulated for the first time, a tabulation that consisted of

two paragraphs – the first relating to employers (LE §9-502(b)(1)) and the second relating

to insurers (LE §9-502(b)(2)). Id. at 847. However, as indicated in the Revisor’s Note,

this revision was not intended to effect a substantive change in the statute. Id., Revisor’s

Note at p. 848.

       The special provisions concerning occupational hearing loss that had appeared in a

single section of the law – most recently, §25A of Article 101 – were also recodified,

without substantive change, but were now split between Subtitle 5 and Subtitle 6 of Title

9 of the new Labor & Employment Article. Id. at pp. 897-99; see Yox, 380 Md. at 335.

Provisions defining the circumstances under which hearing loss would be compensable

now appeared in LE §9-505 and §9-650. Provisions concerning the allocation of liability

                                             23
in hearing loss cases involving multiple employers were recodified as LE §§9-651 and 9-

652.

       Analysis

       The legislative history does not support the two premises of PMA’s textual

argument. The first prong of PMA’s argument is that the absence of the word “insurer” in

the special provisions concerning the allocation of liability in occupational hearing loss

cases means that those provisions did not displace the last injurious exposure rule generally

applicable to occupational disease claims. However, the Legislature decided in 1967 to

enact a new rule, applicable only to hearing loss claims, as a substitute for the bright-line

rule applicable to other occupational disease claims. In place of that bright-line rule, the

1967 amendments substituted an opportunity for an apportionment of liability and a

different bright-line default rule (equal shares) for the bright-line rule applicable to other

occupational diseases. Nothing in the legislative history of the 1967 amendments indicates

that the use of the word “employer” in those provisions signaled a separate method for

allocating liability among an employer’s insurers in those cases.

       The second premise of PMA’s argument is its assumption that the tabulation of the

current codification of the last injurious exposure rule in two paragraphs of LE §9-502(b)

means that they function independently of each other, such that the last injurious exposure

rule may apply to insurers even when it does not apply to employers. That assumption is

contradicted by the legislative history.

       From the inception of the last injurious exposure rule in 1939 to its most recent

recodification 52 years later, it has been evident that the employer and insurer parts of the

                                             24
rule were to function sequentially, not independently, to identify a single payor of liability.

In PMA’s interpretation of the statute, the 1991 code revision that created the tabulation

effected a substantive change in the rule such that insurers would be governed by it even

when employers were not. But there is no indication in the legislative history that the

tabulation created by the 1991 recodification of the rule was intended to change the

operation of the rule. To the contrary, as explained above, the Revisor’s Note to LE §9-

502(b) in the 1991 recodification explicitly states that it was not intended to effect a

substantive change in the rule.

       The sequential operation of the last injurious exposure rule makes sense in the

context of the workers’ compensation law. An insurer is not independently liable to a

claimant without a contractual relationship with an employer of the claimant. Thus, as it

applies in the case of a typical occupational disease, the last injurious exposure rule

necessarily first requires identification of the liable employer – i.e., the last employer

chronologically. Only then does the rule’s provision concerning insurers come into play.

Only the last insurer, chronologically, that has contracted to cover the liability of that last

employer is implicated by the rule. An insurer of a prior employer – whether first, last, or

somewhere in between – is not implicated at all by the rule. Thus, under the last injurious

exposure rule, in most occupational disease cases, liability to the claimant is initially

assigned to only one employer and, if that employer is not self-insured, ultimately to only

one insurer. Only one entity is liable, regardless of the number of potentially liable

                                              25
employers and insurers. However, that is not the case for an occupational hearing loss

claim – even under PMA’s view of the statute. 22

       In essence, PMA argues that LE §9-502(b)(2) relating to insurers in the last injurious

exposure rule should be applied out of context of the rest of that rule and the Act. The

legislative history and purpose of the Act do not support that argument.

       3.      Consequences of Alternative Interpretations

       PMA argues that an interpretation of the Act that does not apply the last injurious

exposure rule to insurers in occupational hearing loss cases will lead to absurd results.

PMA posits an example of a case involving a single employer with three different insurers

over the period of the claimant’s employment. Arguing that it is unclear how liability

would be allocated among those insurers, PMA asserts that the problem would be

compounded in a situation where there are multiple employers, each with multiple insurers,

with the result that there would be onerous litigation over how to allocate liability among

those insurers. 23

       As indicated earlier, however, the allocation challenges that other occupational

diseases pose – notably, the difficulty of identifying the degree to which each set of

injurious exposures over a period of years caused the disease – are not necessarily present

       22
         In PMA’s view, only one insurer may be held liable for a claim of occupational
hearing loss against an employer. But PMA does not dispute that more than one employer
may be liable on such a claim with separate insurers covering the liability of each of those
employers.
       23
          At the same time, PMA concedes that dispensing with the last injurious exposure
rule in a case like this one promotes the availability of insurance for a particular claim.
                                             26
in occupational hearing loss cases. In hearing loss cases, the availability of audiological

testing may allow for a determination of the extent to which a claimant’s hearing has

deteriorated at different points in time. Apparently for that reason, the Legislature did not

deem it absurd to supersede the last injurious exposure rule and provide for the allocation

of liability (when the proof allows) and for the sharing of liability by an alternative bright-

line rule (equal shares) when it does not.

       A conclusion that not every general rule in LE §9-502 concerning occupational

diseases applies to an occupational hearing loss claim is also not absurd in light of the

interpretation of that statute by the State’s highest court. Although there is no case law on

the precise issue presented by this case, 24 the Court of Appeals addressed an analogous

issue in Yox v. Tru-Rol Co., 380 Md. 326 (2004).

       In Yox, the Court faced the question of when the statute of limitations began to run

for an occupational hearing loss claim. Under LE §9-711(b), the general deadline for filing

a claim based on an occupational disease is two years from the date of “disablement” or

the date when the employee first had actual knowledge that the disablement was caused by

the employment.      In turn, LE §9-502, setting out the general provisions governing

       24
          The last injurious exposure rule has been adopted in the workers’ compensation
laws of many other jurisdictions – sometimes, as in Maryland, by statute and sometimes
by case law. E.g., Travelers Insurance Co. v. Cardillo, 225 F.2d 137, 145 (2d Cir.), cert.
denied, 350 U.S. 913 (1955) (adopting last injurious exposure rule for purposes of federal
Longshore & Harbor Workers’ Compensation Act); see also 14 Larson’s Workers’
Compensation Law §153.01 et seq. (2023). However, there is no model act that is the
source of the various statutory provisions; case law in other jurisdictions, which necessarily
relates to the specific provisions of the local law, would offer limited guidance in
construing the Maryland version. Perhaps for that reason, none of the parties has cited case
law from other jurisdictions.

occupational diseases, defines “disablement” to mean that the employee has become

“incapacitated,” as a result of the disease, from performing work in the last occupation

involving the injurious exposure that resulted in the disease. LE §9-502(a). The issue in

Yox was whether the definition of “disablement” in subsection (a) of LE §9-502 applied to

occupational hearing loss claims.

       In deciding that issue, the Court noted that applying the general definition of

“disablement” to occupational hearing loss claims would lead to the same result as in

Belschner – that is, any hearing loss claim for which the claimant could not show

incapacitation would be denied. However, as noted above, the 1967 amendments that

created the special occupational hearing loss provisions were intended to take up the

Belschner Court’s invitation to overturn its holding by liberalizing the statute. In Yox, the

Court recognized that purpose and held that, although the specific provisions regarding

occupational hearing loss that had been enacted in reaction to Belschner did not contain a

separate definition of “disablement,” the general definition of “disablement” in LE §9-

502(a) “does not and cannot apply, because it is wholly inconsistent with the substance and

avowed purpose” of the addition of the occupational hearing loss provisions in 1967. Yox,

380 Md. at 336-37. The Court looked to the specific criteria for compensation in LE §9-

505 and LE §9-650 of the occupational hearing loss provisions for an implicit definition of

“disablement” that would trigger the beginning of the period of limitations in such cases.

Id. at 337-38.

       Thus, despite an argument that the “plain meaning” of the Act required that the

definition of “disablement” generally applicable to occupational disease claims must also

                                             28
apply to claims of occupational hearing loss, 25 the Court held that the special provisions

concerning occupational hearing loss enacted in 1967 required that a different

understanding of the term be applied. In particular, while the general definition of

disablement required that the claimant be incapacitated from performing the claimant’s

job, the legislative history of the 1967 amendments made clear that the primary purpose of

that law was to overturn a case that held just that.

       In the instant case, it is even clearer than in Yox that the General Assembly has

superseded a general provision of LE §9-502 – this time, subsection (b) – in the specific

provisions concerning occupational hearing loss. The consequence that PMA posits as

absurd is thus precisely the consequence that the General Assembly intended.

       4.       Summary

       When the specific provisions relating to occupational hearing loss were added to the

Act in 1967, they did not include a last injurious exposure rule. Indeed, the statutory

sections providing for the impleading of multiple employers and the allocation of liability

directly contradicted that rule. The arbitrary bright-line rule of the last injurious exposure

rule was superseded by a different bright-line allocation rule (equal shares) that was subject

to modification if there was evidence that supported modification of an equal-share

allocation. In the context of the entire Act, the fact that the occupational hearing loss

provisions express liability on a claim by reference to employers and do not specifically

mention insurers does not exempt insurers from those provisions.

       The legislative history of the last injurious exposure rule in Maryland indicates that

it operates sequentially – first applied to employers to identify the liable employer and then,

if that employer is not self-insured, to its insurer(s) to identify the one insurer to be

responsible for paying the claim.       This is antithetical to the regime created by the

occupational hearing loss provisions, both substantively (apportionment) and procedurally

(impleader). Further, there is no indication in the available legislative history that the

General Assembly believed that a claim for occupational hearing loss would be subject to

the last injurious exposure rule. Finally, as the State’s highest court held in Yox, a general

provision governing occupational diseases in LE §9-502 must give way when inconsistent

with the approach that the General Assembly has specified for claims of occupational

hearing loss.

                                         Conclusion

       For the reasons set forth above, we agree with the Commission and the Circuit Court

that the last injurious exposure rule does not apply in allocating liability among insurers of

liable employers for claims of occupational hearing loss under the Act. Accordingly, PMA

may not invoke that rule to deny its appropriate share of liability for Mr. Cree’s claim.
