Negligent Hiring, Retention, and Supervision: A Trust-Building Studio Visit Alone Does Not Establish the Employment Nexus

1. Introduction

In M.P. v Cosby, a divided First Department addressed when an employee’s use of an employer’s premises to gain another person’s trust sufficiently connects later alleged misconduct to the employment relationship. The court held that an allegedly trust-building visit to a television studio, without tortious conduct there or direct use of employer resources in committing the alleged assaults, did not establish the necessary connection for negligent hiring, retention, and supervision liability.

The plaintiff, identified as M.P., sued William Cosby, Jr., and other defendants, including The Carsey-Werner Company, LLC (“CW”), the company associated with producing The Cosby Show. According to the allegations recounted in the dissent, plaintiff first met Cosby on the show’s set in approximately 1987, at his invitation. He allegedly told her that the show wanted to hire her to appear, and potentially sing, in a special episode. She alleged that, on multiple occasions between 1987 and 1990, he gave her drugged beverages and sexually assaulted her while she was unconscious.

Plaintiff sought to hold CW responsible for its own alleged negligence in hiring, retaining, and supervising Cosby. She alleged that CW knew or should have known of his propensity to sexually abuse women and permitted him to exploit the show’s premises and resources without adequate supervision.

The central appellate issue was not whether the alleged assaults occurred or whether Cosby was liable. It was whether the complaint adequately connected those alleged assaults to CW’s employment of Cosby and its provision of premises or resources. By a three-to-two vote, the court found that connection insufficient.

2. Summary of the Opinion

Procedural result

Supreme Court, New York County, had denied CW’s motion to dismiss the negligent hiring, retention, and supervision claim. The First Department reversed that ruling on the law, without costs, granted the motion, and directed entry of judgment dismissing the complaint against CW. The decision did not resolve the claims against the remaining defendants.

The majority’s holding

The majority applied the framework established in Moore Charitable Found. v PJT Partners, Inc. and its recent decision in B.B. v Cosby. It concluded that plaintiff’s single studio visit did not meaningfully distinguish her claim from the claim dismissed in B.B. v Cosby.

The majority emphasized that plaintiff did not allege:

• That Cosby assaulted or even touched her on CW’s premises;
• That he directly used CW property or resources to commit the alleged assaults; or
• That any CW personnel other than Cosby met or spoke with her or knew of her existence.

Allegedly using the studio to impress or “bait” plaintiff was insufficient. The majority distinguished that use from employing company premises or resources as the location or instrumentality of independently tortious or illegal conduct. It also clarified that the significance of a workplace visit depends on its nature, not simply its occurrence or frequency.

The dissent’s position

Justice Gesmer, joined by Justice Kennedy, would have affirmed the denial of dismissal. The dissent considered the studio invitation and purported employment opportunity sufficient to plead that Cosby used resources available through his employment to gain plaintiff’s trust and facilitate the alleged assaults.

In the dissent’s view, the majority drew an unwarranted distinction between using employer resources to make a fraudulent investment proposal appear legitimate and using an employer’s studio and apparent hiring authority to make an alleged grooming process appear legitimate.

3. Analysis of the Precedents Cited

Moore Charitable Found. v PJT Partners, Inc., 40 NY3d 150 (2023)

Moore Charitable Found. v PJT Partners, Inc. supplies the controlling Court of Appeals framework. Ordinary negligence requires a duty owed to the plaintiff, breach of that duty, and an injury proximately resulting from the breach. For employer retention and supervision claims, the complaint must also allege:

1. The employer’s actual or constructive knowledge of the employee’s propensity for the type of conduct that caused the harm;
2. The employer’s knowledge, actual or constructive, of its ability to control the employee and the necessity and opportunity to do so; and
3. Tortious conduct on employer premises or using property or resources available to the employee through employment, including intellectual property and confidential information.

As described in the opinion, the employee in Moore Charitable Found. v PJT Partners, Inc. used his investment bank’s email account, documentation, letterhead, and information about legitimate transactions to perpetrate fraud. Those allegations supported a duty to supervise him for the plaintiff’s benefit.

The majority understood that decision to require more than employer-enabled credibility or access. The company materials in the investment case were used in perpetrating conduct that was itself independently illegal. Here, by contrast, the majority found no allegation of independently tortious conduct during the studio visit or direct use of company resources in committing the assaults.

The dissent understood the same precedent more functionally. In its view, company email, letterhead, and business information mattered because they gave the fraudulent solicitation an appearance of legitimacy. The studio and apparent opportunity to work on the show allegedly served a comparable purpose: they made Cosby seem trustworthy and enabled his subsequent conduct.

The dissent also relied on two additional aspects of the precedent. First, an employer’s notice can be pleaded through allegations that it “should have known” of an employee’s misconduct, including behavior generally known in the community. Second, a special relationship or contractual privity between the employer and the injured person is not required.

Accordingly, the disagreement was not over whether employer resources can support liability for off-premises wrongdoing. Both opinions recognized that possibility. They differed over how closely the resources must be connected to the wrongful conduct at the pleading stage.

B.B. v Cosby, 245 AD3d 498 (1st Dept 2026)

B.B. v Cosby was the majority’s closest factual precedent. It involved similar sexual-misconduct allegations against Cosby and a negligent hiring, retention, and supervision claim against CW. The court had dismissed that claim because the alleged assaults were insufficiently connected to CW’s employment of Cosby.

The earlier complaint did not allege that CW introduced the plaintiff to Cosby or fostered their relationship; that assaults occurred on CW premises; that company property was used in the assaults; that the plaintiff auditioned, worked for the show, or visited its studio; or that company resources facilitated or concealed the misconduct.

The present majority made an important clarification: that list of missing allegations was not a checklist under which pleading any one item necessarily establishes liability. A studio visit could be relevant, but its presence alone was not sufficient.

The majority further characterized the earlier decision as implicitly rejecting the proposition that celebrity authority and influence, standing alone, constitute employer “property” or “resources.”

The dissent disputed that reading. It maintained that the earlier decision established only that the alleged interactions were too attenuated from the employment relationship. Because the present plaintiff alleged an actual studio visit tied to a potential role on the show, the dissent considered the cases materially different.

The new decision therefore extends and clarifies the earlier precedent: mere access to the workplace does not cure an otherwise insufficient employment nexus.

Waterbury v New York City Ballet, Inc., 205 AD3d 154 (1st Dept 2022)

In Waterbury v New York City Ballet, Inc., the plaintiff was a student at the corporate defendant’s official ballet school, and employee defendants allegedly shared intimate images of her during working hours and on work premises.

The majority distinguished that case because the employer’s workplace was connected to the commission of the alleged tortious acts themselves. The present complaint, in its view, alleged only an innocuous studio visit preceding later assaults.

The dissent relied on the precedent’s broader recognition that employer liability can arise where employees cause harm through employer resources or where an employer fails to prevent foreseeable workplace harm. It also invoked the connection between an employer’s control of its premises and its responsibility to regulate conduct there.

Although the plaintiff’s institutional connection in that case helped distinguish its facts, the dissent correctly identified the precedent’s express statement that negligent hiring and retention liability does not require a special relationship with the victim. The present majority’s references to plaintiff’s lack of a relationship with CW should therefore be understood as contextual, not as establishing a new categorical relationship requirement.

C. R. v Episcopal Diocese of New York, 248 AD3d 1 (1st Dept 2025)

The dissent cited C. R. v Episcopal Diocese of New York for the governing dismissal standard: courts accept pleaded facts as true, give the plaintiff every possible favorable inference, and determine whether those facts fit a cognizable legal theory.

The dissent also relied on that decision’s recognition that negligent hiring, retention, and supervision claims are not subject to a statutory requirement of heightened factual specificity. That principle supported its view that allegations of open and notorious abuse known to CW’s employees adequately pleaded notice.

This precedent framed the dissent’s methodological objection. It considered the pleaded grooming-related use of the studio sufficient when evaluated favorably to plaintiff. The majority, however, treated the alleged connection as legally inadequate even assuming the pleaded events.

J.K. v City of New York, 223 AD3d 565 (1st Dept 2024)

The dissent cited J.K. v City of New York alongside the preceding case to address information asymmetry before discovery. Relevant details about an employer’s knowledge and internal supervision may be exclusively within the employer’s possession.

Its significance was limited but important: it supported allowing adequately pleaded claims to proceed without demanding detailed internal information that a plaintiff could not yet obtain. It did not independently resolve the disputed connection between the studio visit and the alleged assaults.

4. Legal Reasoning: The Boundary Between Background Facilitation and Tortious Use

Notice alone does not establish liability

Plaintiff alleged that CW knew or should have known of Cosby’s propensity to abuse women. The majority’s dismissal nevertheless turned on the insufficient employment nexus, not on an express rejection of those notice allegations.

The decision thus separates knowledge of dangerous tendencies from a legally sufficient basis for holding the employer responsible for a particular injury. An employer’s alleged awareness does not automatically make it liable for every subsequent act committed by the employee.

The employment nexus must be substantive

The majority focused on whether CW’s premises or resources were sufficiently involved in the alleged wrongdoing. Its approach distinguishes between resources that create an opportunity to impress someone and resources used as the location or means of committing wrongful conduct.

On that reasoning, the studio’s contribution to Cosby’s credibility was too remote. Plaintiff alleged a visit, but not an assault there or direct use of company resources in the assaults. His celebrity status likewise did not supply the missing connection.

This is not a rule that all actionable misconduct must occur at work. The majority’s discussion of the investment-fraud precedent recognizes that employer resources can connect an employer to wrongdoing elsewhere. Rather, the holding requires a stronger connection than the trust-building role alleged here.

The dissent viewed grooming as part of the causal process

The dissent resisted separating the studio encounter from the alleged assaults. It treated the invitation and purported job opportunity as steps in a continuous process through which Cosby obtained plaintiff’s trust.

It also identified possible measures within CW’s control: regulating meetings on its premises, restricting unsupervised interactions connected with the show, and enforcing protective rules despite alleged notice of misconduct. For the dissent, those allegations connected employer control, foreseeable risk, and eventual harm sufficiently to permit discovery.

The decision concerns pleading, not proof

No trial findings established whether the assaults occurred, what CW actually knew, or whether supervision would have prevented harm. The majority held the complaint legally insufficient against CW. The dissent would have allowed the claim to proceed; it did not conclude that CW had already been proven liable.

Nor did the opinion separately analyze distinct factual theories concerning initial hiring, later retention, and ongoing supervision. It resolved the grouped claim through the common employment-nexus deficiency.

5. Potential Impact

A narrower path for trust-building and grooming allegations

Within the First Department, the decision strengthens an employer’s argument that workplace access, prestige, or credibility alone does not establish negligent hiring, retention, and supervision liability. Plaintiffs relying on preparatory interactions will need to identify why the nature of those interactions creates a legally sufficient connection to the eventual wrongdoing.

Merely adding an allegation that the plaintiff visited the workplace is unlikely to distinguish a claim from B.B. v Cosby. The present opinion expressly makes the nature of the visit more important than its number.

Greater attention to concrete use of employer resources

Future litigation will likely focus on whether premises, communications systems, documents, staff, or other resources were actually used in committing or facilitating actionable misconduct, rather than simply providing its background. The earlier decision’s list of absent facts may guide that inquiry, but this opinion warns that no single listed fact automatically establishes liability.

Because the ruling rests on insufficient nexus, additional allegations of employer notice alone may not overcome its reasoning.

A continuing interpretive dispute

The dissent exposes a substantial question about the reach of Moore Charitable Found. v PJT Partners, Inc.: must employer resources be directly involved in independently wrongful conduct, or can their use to obtain trust sufficiently connect the employer to a later tort?

The division may influence later appellate arguments concerning grooming, recruitment, apparent employment authority, and off-premises misconduct. Nevertheless, this decision does not establish immunity for celebrity employers, require contractual privity with the victim, or make workplace location an indispensable condition of liability.

6. Complex Concepts Simplified

Negligent hiring, retention, and supervision

Claims that an employer’s own unreasonable hiring, continued employment, or oversight contributed to an employee’s harmful conduct.

Actual or constructive knowledge

Actual knowledge means the employer knew. Constructive knowledge means it should have known under the circumstances.

Employment nexus

A sufficiently meaningful connection between the employment relationship, employer premises or resources, and the injury. Employment alone is not enough.

Proximate cause

A legally sufficient connection between the defendant’s alleged negligence and the injury, rather than a merely remote contribution.

Situs and instrumentality

“Situs” means the place where wrongdoing occurred; “instrumentality” means a means or resource used to carry it out.

Independent tortious or illegal conduct

Conduct that is itself a civil wrong or unlawful act, as opposed to conduct alleged only to have created trust or an opportunity for later wrongdoing.

Direct negligence versus vicarious liability

This case concerns CW’s alleged negligence in managing an employee, not automatic responsibility merely because the alleged wrongdoer was its employee.

7. Conclusion

M.P. v Cosby clarifies that a trust-building workplace visit, without more, does not establish the employment nexus necessary for negligent hiring, retention, and supervision liability. The majority required a closer connection between employer premises or resources and independently wrongful conduct than plaintiff’s allegations supplied.

The dissent’s competing view highlights the decision’s broader significance: whether employer-enabled grooming should be evaluated as part of the causal mechanism of later abuse or as insufficiently connected preparatory conduct. The binding holding adopts the latter approach on these pleaded facts, while preserving liability where employer premises or resources are sufficiently involved in the wrongdoing.
