The federal Court of Appeals for the Fourth Circuit certified to this Court the following question of law:
We answer the certified question in the negative. For reasons to be explained, we hold that § 19-501 of the Maryland Security Guards Act is a codification of Maryland's common law doctrine of respondeat superior and does not broaden the scope of vicarious liability of the employers of security guards for their employees' acts beyond these principles.
I. FACTUAL AND PROCEDURAL BACKGROUND.
A summary of the certified facts of this case deserve mention.
Aaron Speed, one of the arsonists, had been hired originally by SSA in November 2003, without the benefit of checking his references. Speed quit his employment with SSA in August 2004, after being reprimanded for "careless and aggressive conduct." One of Speed's supervisors placed a recommendation in Speed's personnel file that he not be considered for rehire. Despite this recommendation, Speed was rehired by SSA in November 2004.
As part of the conspiracy to set fire to the homes, Speed left his guard post at the development on 3 December 2004 in order to stash fuel that would be used by the others to set fire to the homes. While on-duty, Speed created also a map of the neighborhood, indicating which houses were owned or contracted for by racial minorities.
William Fitzpatrick, another SSA employee, was alleged also to have conspired to commit the arson.
Appellants asserted ultimately various civil claims in the U.S. District Court for the District of Maryland against SSA, two of its corporate affiliates, and the five convicted arsonists. One of Appellants' theories of SSA's liability contended that Maryland Code (2000, 2010 Repl.Vol.), Business Occupations & Professions Article, § 19-501 (hereinafter the Maryland Security Guards Act § 19-501) established a basis for SSA's strict liability.
Deciding a motion for summary judgment filed by SSA, Judge Alexander Williams, Jr. of the U.S. District Court held that the Maryland Security Guards Act § 19-501 was merely a codification of the common law and did not expand the doctrine of respondeat superior, contrary to the plaintiffs' contentions regarding SSA's strict liability for Speed's and Fitzpatrick's intentional torts and civil rights violations. Antonio v. Sec. Servs. of Am., LLC, 701 F.Supp.2d 749, 766 (D.Md.2010). After concluding that any intentional acts of Speed and Fitzpatrick were, considering the facts in the light most favorable to
On appeal, Appellants asked the federal Court of Appeals for the Fourth Circuit to reverse the District Court's decisions: (1) granting summary judgment in SSA's favor as to the negligence claims; (2) granting summary judgment in SSA's favor as to the claims premised on strict liability under the Maryland Security Guards Act § 19-501; and, (3) denying the request to certify to us the question regarding the interpretation of the Maryland Security Guards Act § 19-501. The federal appellate court, after affirming the District Court's grant of summary judgment as to the negligence claims, turned to the question requiring interpretation of the Maryland Security Guards Act.
Appellants argued, as they do now, that the Maryland Security Guards Act extends the vicarious liability of security guard agencies beyond the Maryland common law doctrine of respondeat superior. The federal appellate court considered the text of the statute and, after applying Maryland's cannons of statutory construction, concluded that there were conflicting indications as to the meaning of the Maryland Security Guards Act § 19-501. Thus, the Court certified the question to us to resolve the uncertainty.
II. OUR ANALYSIS.
We may answer questions certified to us by a United States court or the appellate court of another state or of a tribe if the answer might be determinative of an issue before the certifying court and there is no controlling Maryland authority. Md.Code (1974, 2013 Repl.Vol.), Courts & Judicial Proceedings Art., § 12-603. The Maryland Security Guards Act § 19-501 has not been interpreted by Maryland's appellate courts before and its application could be dispositive of whether Appellants' strict liability contentions will allow certain of its claims to survive summary judgment.
The District Court dismissed several of Appellants' claims because the alleged torts and fair housing violations committed by SSA's employees were beyond the scope of their employment. Appellants argued before the federal District Court, the federal Court of Appeals, and now us that the Maryland Security Guards Act § 19-501 imposes liability on SSA for the actions of Speed and Fitzpatrick beyond those for which SSA would be liable under Maryland's common law doctrine of respondeat superior.
The relevant portion of the Act, § 19-501, provides: "A licensed security guard agency is responsible for the acts of each
When interpreting statutes, our overarching goal is to ascertain and implement the intention of the Legislature. Witte v. Azarian, 369 Md. 518, 525, 801 A.2d 160, 165 (2002). We turn first to the words of the statute. If, in pursuit of the North Star of intent, the words of the statute, given their common and ordinary meaning, are unambiguous and express a plain meaning, our inquiry stops normally and we interpret the statute as written. Oaks v. Connors, 339 Md. 24, 35, 660 A.2d 423, 429 (1995). If the text is ambiguous, however, we look to other evidence of the Legislature's intent, including the relevant statute's legislative history, the structure of the statute, the relationship of the statute to other laws, and the relative rationality of competing constructions. Witte, 369 Md. at 525-26, 801 A.2d at 165.
There is, however, one important and particularly relevant interpretive principle reining-in our quest to elucidate the will of the Legislature: we will not presume abrogation of the common law unless the Legislature's intent to do so is clear. Suter v. Stuckey, 402 Md. 211, 232, 935 A.2d 731, 743-44 (2007) (citing Robinson v. State, 353 Md. 683, 693, 728 A.2d 698, 702 (1999); Lutz v. State, 167 Md. 12, 15, 172 A. 354, 355-356 (1934)). When the intent of the Legislature is unclear with regard to abrogation, we will interpret the statute to be congruent with the common law.
A. Abrogation Here of the Common Law?
Maryland's common law doctrine of respondeat superior holds employers liable "for the tortious conduct of ... [an] employee committed while the servant was acting within the scope of the employment relationship." Barclay v. Briscoe, 427 Md. 270, 283, 47 A.3d 560, 567 (2012) (quoting Embrey v. Holly, 293 Md. 128, 134, 442 A.2d 966, 969 (1982)). For employee conduct to be within the scope of employment, "the acts must have been in furtherance of the employer's business and authorized by the employer." Barclay, 427 Md. at 283, 47 A.3d at 567-68 (quoting S. Mgmt. Corp. v. Taha, 378 Md. 461, 481, 836 A.2d 627, 638 (2003)). Expanding the vicarious liability of security guard agencies by statute to include all on-duty acts of employees (strict liability) would alter significantly the common law scheme of respondeat superior and amount to an abrogation of the common law.
The common law doctrine of respondeat superior not only holds employers liable for the actions of their employees in furtherance of the employer's business, but also limits an employer's liability to those situations. It is central to the doctrine that an employee's acts committed outside the scope of employment, i.e., not in the furtherance of the employer's
A temporal interpretation of the Maryland Security Guards Act § 19-501 would eliminate the distinction between employees' acts within the scope of employment and those outside the scope of employment. Rather than turning on the character of employee acts, the focus would be on when the acts happened and whether the security guard was on duty. Security guard agencies would be liable for a broader set of acts of their employees, including, according to Appellants, even acts in direct opposition to the employers' interests. Such a change in employer liability would alter fundamentally the common law.
Contrary to Appellants' arguments, interpreting the Maryland Security Guards Act § 19-501 to impose vicarious liability on security guard agencies for all on-duty acts of their employees would operate more than to supplement the common law. Statutes we have held to supplement, rather than abrogate, the common law provide typically alternative remedies or criminal sanctions. See, e.g., Nickens v. Mount Vernon Realty Grp., LLC, 429 Md. 53, 74-75, 54 A.3d 742, 755-56 (2012) (holding that a Baltimore City ordinance providing for a statutory eviction scheme supplemented, rather than abrogated, the common law remedy of peaceable self-help); Genies v. State, 426 Md. 148, 159, 43 A.3d 1007, 1013 (2012) (holding that a statute creating a separate criminal offense for inmates exposing their private parts to correctional officers of the opposite sex as a means to abuse corrections officers did not abrogate the pre-existing common law crime of indecent exposure). Appellants' interpretation of the Maryland Security Guards Act § 19-501, in contrast, would not create a new cause of action, but rather would modify the liability of security guard agencies for existing torts committed by their employees.
The common law doctrine of respondeat superior answers the question: When is an employer liable for the torts of its employee? The Maryland Security Guards Act § 19-501 answers the same question with specific reference to employers who are security guard agencies. To change the answer amounts to an abrogation of the common law. Therefore, we look for an abundantly clear intent on the part of the Legislature to change the common law by its adoption of § 19-501.
B. Plain Language of the Statute
The Maryland Security Guards Act § 19-501 holds clearly and unambiguously licensed security guard agencies liable civilly for some acts of their employees. The parties disagree which acts of employees come within the statute. At issue is whether the Legislature intended the phrase "while the employee is conducting
Appellants' major premise revolves around the temporal meaning of "while." When used grammatically as a conjunction, as it is in the Maryland Security Guards Act § 19-501, "while" means typically "during," "throughout the time that," or "as long as." Webster's New Universal Unabridged 2084 (1983).
The Maryland Security Guards Act defines "conducting the business of the agency." A licensed security guard agency is defined as "a person who is licensed by the Secretary to conduct a business that provides security guard services." Maryland Security Guards Act § 19-101(g). Security guard services are defined as "any activity that is performed for compensation as a security guard to protect any individual or property...." Maryland Security Guards Act § 19-101(l).
Combining these terms, Appellants arrive at the following meaning of the Maryland Security Guards Act § 19-501: A licensed security guard agency is liable for the actions of its employees occurring during the time that the employee is performing any activity for compensation to protect an individual or property.
SSA argues, in response, that if the General Assembly intended a temporal construction, extending liability to all acts of on-duty employees, it would have done so explicitly.
The language of the Maryland Security Guards Act § 19-501 is subject to differing reasonable interpretations. Although Appellants' argument may sound logical, when taken as a whole, the phase "while the employee is conducting the business of the agency" could be understood as well as having the same meaning as the common law doctrine of respondeat superior. The common law doctrine imposes liability only for acts by an employee furthering the employer's business, Hopkins Chem. Co. v. Read Drug & Chem. Co., 124 Md. 210, 214, 92 A. 478, 479-480 (1914) (stating that employers are liable if an employee's acts were "within the scope of his employment; not whether they were done while prosecuting
C. Context of the Statute
The crux of the Maryland Security Guards Act is the licensing scheme of security guard agencies, not the imposition of civil liability. The majority of the Act governs how an agency applies for and obtains the required licensure from the State to conduct a security guard agency. The "Miscellaneous Provisions" of the Act, of which § 19-501 is a part, however, contain sections addressed to the civil liability of security guard agencies. See the Maryland Security Guards Act §§ 19-504 (requiring a minimum amount of general liability insurance for agencies with more than five employees); 19-505(a)-(b) (requiring consent to venue); 19-505(f) (allowing for service of legal process under certain circumstances on Maryland Secretary of State). The internal structure of the Maryland Security Guards Act contributes nothing to illumination of the intentions of the General Assembly.
The broader context of the Maryland Code provides some support for the Appellants' interpretation of the Maryland Security Guards Act § 19-501. In other statutory schemes within the Code, the General Assembly uses the common law term "scope of employment." See, e.g., Md. Code (1999, 2007 Repl.Vol.), Agriculture Art., § 4-127 ("when construing or enforcing any provision of this subtitle, every act, omission, or failure of any person acting within the scope of employment or office and acting for or employed by another person is the act, omission, or failure of that person as well as of the person committing the act"); Md.Code (1999, 2007 Repl.Vol.), Business Occupations & Professions Art., § 12-501(b)(2) (using the term "scope of employment" regarding insurance requirements for licensed plumbers); Md.Code (1992, 2010 Repl.Vol.), Business Regulation Art., § 9A-402(b)(2) (using the term "scope of employment" regarding insurance requirements for licensed heating, ventilation, and air-conditioning workers); Md.Code (1974, 2013 Repl.Vol.), Courts & Judicial Proceedings Art., § 5-303(b) ("a local government shall be liable for any judgment against its employee for damages resulting from tortious acts or omissions committed by the employee within the scope of employment with the local government"); Md.Code (2002, 2012 Repl. Vol.), Criminal Law Art., § 10-108 (creating an exception to the criminal statute for possession of "a tobacco product or cigarette rolling paper by a minor who is acting as the agent of the minor's employer within the scope of employment"); Md. Code (1978, 2014 Repl.Vol.), Education Art., § 6-111(a) (providing for full pay for employees absent due to disability resulting from an assault "while in the scope of board employment"); Md.Code (2007), Human Services Art., § 3-406 (prohibiting the State from paying judgments awarded against an employee under the section for acts or omissions occurring "outside the scope of employment"); Md.Code (1988, 2010 Repl. Vol.), Tax-General Art., § 1-101 (defining "Comptroller" to include "an employee of the Comptroller acting within the scope of employment"). It seems from
Considering the language of the Maryland Security Guards Act §§ 19-501 in the foregoing context of the Maryland Code adds some weight to the Appellants' interpretation. One might anticipate that the General Assembly would use the term "scope of employment" here if it intended to codify common law respondeat superior. In isolation, however, the absence of this term in § 19-501 does not provide sufficiently clear evidence of the General Assembly's intent to abrogate the common law.
D. Legislative History
The language of the Maryland Security Guards Act § 19-501 has its genesis in Senate Bill 968 of the 1986 session, which codified a regulatory scheme as Md.Code (1999, 2007 Repl.Vol.), Business Occupations & Professions Art., § 13-601 (hereinafter the Maryland Private Detectives Act § 13-601). Security guard agencies remained regulated as private detectives under the Business Occupations & Professions Article of the Maryland Code until 1996 when House Bill 42 separated the Code's treatment of security guard agencies into its own title. 1996 Maryland Laws Ch. 602 (which established the current regulatory scheme). The same language regarding liability was used in House Bill 42 as existed in the prior Article. Id. Thus, the legislative history of § 13-601 of the Business Occupations & Professions Article of the Maryland Code, which covered civil liability for private detective agencies and security guard agencies before the reorganization, is informative regarding the analogous § 19-501 of the Maryland Security Guards Act.
Senate Bill 968 of 1986 was introduced as a bill separate from a recodification initiative of the Maryland Code then underway. The separate bill was necessary because the General Assembly wished to address perceived substantive problems regarding the laws pertaining to private detectives. Department of Legislative Reference, Report on Senate Bill 968 at 1 (1986) (hereinafter "Report on Senate Bill 968"). Several issues with the pre-existing statutory language regarding the licensing and provision of private detective services were identified in the Report on Senate Bill 968. The Report did not identify any problem with the regime of vicarious liability of private detective agencies or security guard agencies then in force. Notably, it stated: "[F]or the most part, the proposals under the bill find their basis in actual law and practice and do not deviate substantially from the current law as it is now is applied. There is no attempt under the revision to change existing underlying policy." Report on Senate Bill 968 at 2.
The Report highlighted elements of Senate Bill 968 warranting special attention by the General Assembly, but in doing so did not mention § 591 of the Bill, the language of which would be codified later as Maryland Private Detectives Act § 13-601 and even later replicated in the Maryland Security Guards Act § 19-501. Of the part of Senate Bill 968 which contained the relevant language, the Report noted:
Report on Senate Bill 968 at 8. In the opinion of the authors of the Report, the
The Bill Analysis of the Senate Economic and Environmental Affairs Committee interpreted similarly the "while the employee is conducting the business of the agency" language of Senate Bill 968. The Bill Analysis noted that "[t]he substantive changes are included for the limited purpose of clarifying existing law." Department of Legislative Reference, Bill Analysis, Senate Economic and Environmental Affairs Committee at 1 (1986) (hereinafter Bill Analysis). Each section of the Bill was discussed in the Bill Analysis. For § 591, it observed that the Bill "[s]pecifies that the agency is responsible for the acts of its employees by clarifying provisions of Article 56, Section 81(a)(1)." Bill Analysis at 7.
The Summary of Committee Report on Senate Bill 968 did not note anything of consequence regarding the vicarious liability of security guard agencies or private detective agencies. The Summary reiterated that "[t]he purpose of the bill is to clarify the current law without changing existing underlying policy." Department of Legislative Affairs, Summary of Committee Report, Senate Economic and Environmental Affairs Committee at 2 (1986) (hereinafter Summary of Committee Report). The Summary further noted that Senate Bill 968 "clarifies current law and sets forth explicit processes that are not included under current law." Summary of Committee Report at 1. The legislative history of the Bill indicates overwhelmingly to us, at every turn, that the intent of the Legislature was to reiterate the law regarding security guard agencies' vicarious liability as it existed at that time.
Appellants argue that the law prior to Senate Bill 968 imposed strict liability on security guard agencies. They point also to the rejection of a proposed amendment to reword the relevant section of the Bill to incorporate the common law term "scope of employment" as evidence of the General Assembly's rejection of SSA's interpretation of the statute.
Prior to adoption of Senate Bill 968 of 1986, Md.Code (1957, 1979 Repl.Vol., 1983 Cum.Supp.), Article 56, § 81(a), enacted originally in 1951, governed the vicarious liability of security guard agencies for the acts of their employees. Section 81(a) provided:
Id. According to the legislative history, the General Assembly intended to incorporate the meaning of this statute into Senate Bill 968 of 1986, which later segued into the Maryland Security Guards Act § 19-501. There is little evidence, however, from which we could uncover the intent of the Legislature regarding the 1951 Act.
The text of the 1951 statute does not establish, on its face, the General Assembly's clear intention to abrogate the common law. The exact meaning of that statute is as ambiguous, in its fashion, as is the present § 19-501. The text holding the
Appellants make a more nuanced additional argument for reading the predecessor and current statutes as abrogating the common law. They point out that the 1951 Act was enacted two years after Apex Smelting Co. v. Burns, 175 F.2d 978 (7th Cir.1949). In Apex Smelting, the federal Court of Appeals for the Seventh Circuit upheld a directed verdict in favor of a security guard agency, finding that under Illinois' negligence and respondeat superior jurisprudence the agency was not liable for an employee's act of arson. Id. at 981. Appellants claim that the Maryland General Assembly reacted to the Seventh Circuit case by enacting the 1951 Act, intending that a case similar to Apex Smelting would come to a different result in Maryland as a consequence.
After Apex Smelting, the Illinois Legislature formulated a statute similar to Maryland's 1951 Act. The Illinois statute read:
Stewart Warner Corp. v. Burns Int'l Sec. Servs., Inc., 353 F.Supp. 1387, 1389 (N.D.Ill.1973). Applying the statute in Stewart Warner Corp. v. Burns Int'l Sec. Servs., Inc. (involving a Chicago arson committed by an on-duty security guard), the U.S. District Court for the Northern District of Illinois held that the statute broadened the scope of vicarious liability of security guard agencies to include all wrongful acts of employees "so long as they were committed while the employee was actually on the job." Id.
Appellants' argument continues by pointing out that subsequently the "good conduct" language (similar to both Maryland's 1951 Act and the Illinois statute) became controversial nationally. Some courts interpreted broadly similar statutes as the Stewart Warner court did. See, e.g., Simmons, Inc. v. Pinkerton's, Inc., 762 F.2d 591, 596-97 (7th Cir.1985). Other courts, construed the "good conduct in the business" language to merely codify merely the common law. Knouse Foods Co-op., Inc. v. Burns Int'l Sec. Servs., Inc., 519 F.Supp. 867, 869 (E.D.Pa.1981); Hoover Ball & Bearing Co. v. Pinkerton's, Inc., 500 F.Supp. 673, 675 (W.D.Mich. 1980).
Although Appellants advance an alluring causation narrative spanning decades and weaving through multiple related statutes and acts of the General Assembly, under close scrutiny it amounts ultimately to nothing more than plausible conjecture. It is equally likely that a general desire for implementation of a licensing regime for private detective and security guard agencies provided the motivation for the 1951 Act, with the Legislature unaware of or unconcerned with the Seventh Circuit's decision in Apex Smelting.
Appellants point also to a failed amendment to Senate Bill 968 that proposed to clarify that private detective and security guard agencies would be liable only for the acts of employees within the scope of employment. The Maryland Association of Contract Guard Services, a trade group, proposed to the Senate Committee on Economic and Environmental Affairs to change the language of § 591 of Senate Bill 968 to read: "A private detective agency is responsible for the acts of each of its employees if the acts are within the scope of the employment." Loughlin Security Agency, Inc., Proposed Changes to Senate Bill 968 `Maryland Private Detectives Act', Senate Committee on Economic and Environmental Affairs (1986) (hereinafter Proposed Changes to Senate Bill 968). Senator Francis Kelly sponsored the amendment before the Committee. Francis Kelly & Maryland Association of Contract Guard Services, Amendment to Senate Bill No. 968 (1968).
The trade group's written testimony explaining the proposed change justified it as desirable because the extant phrase imposing liability — "while the employee is conducting the business of the agency" — was ambiguous. Proposed Changes to Senate Bill 968. The proposed change, it was contended, would make clear that security guard agencies were subject to common law vicarious liability for acts of employees. Id. The Committee declined to recommend favorably to the floor the proposed amendment for the second reading of the Bill. The Bill file maintained by the
Consideration of failed amendment proposals can be useful sometimes in ascertaining or confirming legislative intent. State v. Bell, 351 Md. 709, 721, 720 A.2d 311, 317 (1998); NCR Corp. v. Comptroller of the Treasury, Income Tax Div., 313 Md. 118, 125, 544 A.2d 764, 767 (1988); see also Ishola v. State, 404 Md. 155, 166, 945 A.2d 1273, 1279 (2008) (using the rejection of a proposed amendment as evidence of legislative intent). Failed efforts to amend a proposed bill, however, are not conclusive proof usually of legislative will. City of Baltimore Dev. Corp. v. Carmel Realty Associates, 395 Md. 299, 329, 910 A.2d 406, 424 (2006); Auto. Trade Ass'n of Maryland, Inc. v. Ins. Com'r, 292 Md. 15, 24, 437 A.2d 199, 203 (1981). This is because there can be a myriad of reasons that could explain the Legislature's decision not to incorporate a proposed amendment. City of Baltimore Dev. Corp., 395 Md. at 329, 910 A.2d at 424.
Absent a clear indication in the legislative record, it is as likely that the effort to amend Senate Bill 968 in committee failed because, in the Committee's view, the Bill reflected already common law vicarious liability as it is that the Committee intended to abrogate the common law by reporting an unamended version of the Bill to the floor. Overall, the legislative history of Senate Bill 968 does not illuminate any clear understanding of the Maryland Security Guards Act § 19-501 as abrogating the common law.
E. Policy Considerations
Consideration of the practical consequences of divergent interpretations of an ambiguous statute may provide insight into its meaning. When "confronted with ambiguity regarding legislative intent, it is our duty to announce a rule that we are convinced is best supported by sound jurisprudential policy germane to the pursuit of legislative intent." Haas v. Lockheed Martin Corp., 396 Md. 469, 493, 914 A.2d 735, 749 (2007). In some cases, policy considerations may outweigh other principles of statutory construction. Id.
Appellants urge that their interpretation of the Maryland Security Guards Act § 19-501 — that it imposes liability vicariously on security guard agencies for all acts of their employees committed while the employee is on-duty — represents the best policy, and the one that the Legislature aimed to enact. As this theory proceeds, security guard agencies are in a better position to screen their employees and manage them to ensure that they do not cause harm to others. The inherent ability of security guards to inflict harm on others, in part because of the trust placed in them as a result of Maryland's licensing scheme, justifies the additional responsibility placed on security guard agencies. Moreover, security guard agencies, as opposed to injured persons, are in a better position to plan for and absorb any harm caused by their employees. Appellants idealize their reading of the statute as leading to a more fair allocation of burdens, assigning responsibility to the party with greater information, and, implicitly, resulting in better management of security guards.
Appellant's policy arguments are appealing, but, as SSA offers, there are countervailing considerations. Most convincing of them is the wide range of potential acts for which security agencies could become liable were Appellants' interpretation to be endorsed. Security guard agencies would be liable for an employee's acts unrelated completely to their employment or the special trust placed in them. A security guard agency could become liable, for example,
As noted earlier, Appellants, in their reply brief, propose a limitation on their interpretation of the statute that would prevent the kind of absurd results of which SSA warns. They would add the requirement of a nexus between an employee's on-duty wrongdoing and his or her provision of security services (such that the alleged tort is incident to the employee conducting the agency's business) before liability could arise under the Maryland Security Guards Act § 19-501. Appellants provide, beyond mere benevolence, no principled support for this additional requirement in the text of the statute or any indicia of legislative intent.
Although the requirement of such a nexus might dissipate the problematic hypotheticals suggested by SSA, that it was even proposed stands in opposition to the policy considerations underlying our rule of construction by which we interpret statutes in accordance with the common law, absent clear intent of abrogation. Ultimately, these policy considerations overcome whatever benefits might arise from the interpretation of the Maryland Security Guards Act § 19-501 as proposed by Appellants.
Even seemingly small changes to the law, though motivated by conciliation and good intentions, often require future clarification, as Appellants' offered interpretation of the Maryland Security Guards Act § 19-501 demonstrates. Courts would have to determine eventually what "nexus" between employees' on-duty wrongdoing and providing security services is sufficient to impose vicarious liability on employers. Because neither the statute nor its legislative history provides guidance on that score, courts would be developing the nexus analysis from whole cloth, resulting in uncertainty in the public and business arenas until fleshed out. The one nexus that is well understood by lawyers and judges — within the scope of employment — would be entombed were we to accept Appellants' offer in this regard.
The common law doctrine of respondeat superior has its genesis in 17th and 18th Century England. Christine W. Young, Comment, Respondeat Superior: A Clarification and Broadening of the Current "Scope of Employment" Test, 30 Santa Clara L.Rev. 599, 601 (1990). The doctrine was adopted by courts in the United States and, over time, broadened to incorporate more acts of the employee. See generally id. (describing the adoption of respondeat superior by American courts and outlining its expansion in California). The common law has the advantage of the collective wisdom of a multitude of courts refining the doctrine over centuries. We are not convinced that the policy considerations that Appellants offer in support of their interpretation of the Maryland Security Guards Act § 19-501 are more desirable than (or an improvement over) those underlying the common law.
Considering the ambiguity of the Maryland Security Guards Act § 19-501, its context in the Maryland Code, its legislative history, and the policy considerations of alternative interpretations, we conclude that the Legislature has not indicated to our satisfaction a clear intent to abrogate the common law. We hold therefore that the Maryland Security Guards Act § 19-501 has the same meaning as Maryland's common law doctrine of respondeat superior. Thus, we answer the certified question in the negative.
Appellants' reasoning is misguided. Their interpretation would change the core of Maryland's common law principles of vicarious liability of employers of security guards. Even if there were some remaining vestiges of the common law scheme of vicarious liability, this would not diminish the significant changes advanced by Appellants that would amount to abrogation.
