Vicarious Liability: When One Party Answers for Another's Conduct — Respondeat Superior Explained

By Steve Levine · Updated July 2, 2026 · 8 min read

Quick Answer

Vicarious liability is legal responsibility for someone else's wrongful act, imposed on a party that did nothing wrong itself. The core form is respondeat superior (“let the superior answer”): an employer is liable for torts its employees commit within the scope of their employment. The doctrine rests on agency principles — actual authority, apparent authority, and ratification — and those same principles let plaintiffs hold a company liable under the TCPA for robocalls placed by third-party marketers on its behalf. It contrasts with direct claims like negligent hiring or supervision, where the employer's own carelessness is the wrong. In class actions and mass torts, vicarious liability is often what connects a solvent defendant to conduct carried out by individuals, agents, franchisees, or vendors.

What Vicarious Liability Is

Tort law usually requires fault: you pay for the harms you negligently or intentionally cause. Vicarious liability is the major exception — a form of strict, imputed responsibility in which one party answers for another's wrongful act because of the relationship between them, not because of anything blameworthy it did itself. The paradigm relationships are employer–employee and principal–agent.

The policy rationale is old and practical. The enterprise that profits from an activity, selects and controls the people who carry it out, and can spread the cost of accidents through pricing and insurance should bear the losses that the activity predictably generates — rather than leaving an injured person to collect from a judgment-proof individual. In litigation terms, vicarious liability is frequently what makes a case viable at all: the driver, caller, or clerk who committed the act rarely has the assets to compensate a class, while the enterprise behind them does.

Respondeat Superior & Scope of Employment

Respondeat superior — Latin for “let the superior answer” — makes an employer liable for torts committed by employees acting within the scope of their employment. The employee remains personally liable too, but the plaintiff can recover from the employer, which is where recovery realistically comes from. Everything turns on the scope-of-employment test, which courts commonly frame around three factors: whether the conduct was of the kind the employee was hired to perform; whether it occurred substantially within the authorized time and space of the job; and whether it was motivated, at least in part, by a purpose to serve the employer.

A delivery driver who causes a crash while running a route is squarely in scope. The classic gray areas get their own vocabulary: a detour (a minor deviation — stopping for coffee mid-route) usually stays within scope, while a frolic (abandoning the job for a purely personal errand) falls outside it. Intentional wrongdoing pursued for purely personal reasons is generally outside the scope, though some jurisdictions extend liability where the job itself created the risk of the misconduct. When an act falls outside the scope, plaintiffs pivot to the direct-liability theories discussed below.

Agency Principles: Authority & Ratification

Respondeat superior is one application of the broader law of agency — the body of rules governing when a principal is bound by the acts of an agent. Outside the employment setting, courts ask whether an agency relationship existed and whether the agent acted with authority. The three recurring theories are:

  1. Actual authority. The principal, expressly or implicitly, directed or authorized the agent's conduct — instructions, contracts, scripts, campaign approvals.
  2. Apparent authority. The principal's own words or conduct led third parties reasonably to believe the actor was acting on the principal's behalf — letting a marketer use the company's name, branding, pricing, or customer systems.
  3. Ratification. The principal accepted the benefits of the agent's conduct after the fact, knowing (or deliberately avoiding knowing) the material facts — keeping the sales an unlawful campaign generated.
These theories matter enormously in modern consumer litigation, because companies increasingly act through layers of vendors, lead generators, resellers, and franchisees. Agency is the legal thread plaintiffs use to connect the brand at the top to the conduct at the bottom — and whether that thread holds is a fact-intensive question about control, knowledge, and benefit.

TCPA Vicarious Liability for Telemarketing

The highest-volume application of agency law in class actions is the Telephone Consumer Protection Act (TCPA). The company whose product a robocall pitches almost never dials the call itself — third-party telemarketers, lead generators, and independent agents do. In a 2013 declaratory ruling involving DISH Network, the FCC concluded that a seller, while not directly liable for calls it did not initiate, may be held vicariously liable under federal common-law agency principles — actual authority, apparent authority, or ratification — for TCPA violations committed by third-party telemarketers acting on its behalf. Courts applying that framework examine who supplied the calling lists and scripts, who controlled the campaign, and who kept the resulting sales.

That is why TCPA class actions name the brand being marketed, not just the call center — the complaint alleges the callers were the brand's agents. Settlements in this space resolve those agency allegations without adjudicating them (and typically without any admission of wrongdoing). Current examples on OCA include the Farmers Insurance TCPA do-not-call settlement, which resolves claims over telemarketing calls placed by agents marketing Farmers products, and the Motive Technologies prerecorded-call settlement.

Franchisors, Staffing Agencies & Contractors

The same control-based logic governs three other recurring contexts. Franchising: a franchisor is not automatically liable for a franchisee's torts or employment violations; liability generally depends on how much control the franchisor retains over the specific day-to-day conduct at issue (or on apparent-agency reliance by customers who reasonably thought they were dealing with the brand itself). Uniform branding alone usually is not enough. Staffing: when a staffing agency supplies workers to a client, both entities can face responsibility — wage-and-hour law uses joint employer tests keyed to control over hiring, pay, schedules, and supervision, which is why wage-and-hour class actions often name the agency and the client together.

Independent contractors: the general rule is that respondeat superior does not extend to a true independent contractor's torts — which is precisely why worker classification is so hotly contested. The exceptions swallow much of the rule: retained control over the manner of the work, non-delegable duties, inherently dangerous activities, apparent agency, and — most importantly for class litigation — the argument that the “contractors” are really employees under the governing test. That fight is covered in our companion guide to independent-contractor misclassification.

Vicarious vs. Direct Liability in Class Actions

Vicarious liability should be distinguished from the employer's direct liability for its own negligence. Negligent hiring, retention, and supervision claims allege the company itself was careless — it hired someone with disqualifying red flags, kept them on after complaints, or failed to supervise — and those claims can reach conduct outside the scope of employment, where respondeat superior stops. Plaintiffs commonly plead both: imputed liability for in-scope conduct, direct negligence for the employer's own failures. In mass torts, the distinction shapes discovery (agency theories demand proof of control and knowledge) and can matter for insurance coverage and punitive-damages exposure.

For class actions, agency theories carry a structural advantage and a structural risk. The advantage: they aim at a single enterprise-level defendant, which fits the classwide-proof model — one campaign, one set of scripts, one principal. The risk: agency is fact-intensive, and defendants argue that authority and control varied caller-by-caller or location-by-location, making individualized issues predominate. How that tension resolves often decides whether a vicarious-liability class gets certified at all. As always, allegations that an agency relationship existed are just allegations until proven, and settlements resolve those claims without admissions.

Frequently Asked Questions

What is vicarious liability?

Vicarious liability is legal responsibility for someone else's wrongful act, imposed without any personal fault by the party held liable. The most familiar form is respondeat superior — 'let the superior answer' — under which an employer is liable for torts its employees commit while acting within the scope of their employment. The rationale is that the business that benefits from an activity, and is best positioned to control and insure against its risks, should bear the losses that activity causes.

What does 'scope of employment' mean for respondeat superior?

An employer is vicariously liable only for employee conduct within the scope of employment — generally, acts of the kind the employee was hired to perform, occurring substantially within authorized time and space limits, and motivated at least in part by a purpose to serve the employer. A delivery driver causing a crash on a route is a classic in-scope example; courts distinguish minor deviations ('detours,' still in scope) from purely personal errands ('frolics,' outside it). Intentional misconduct pursued for purely personal reasons usually falls outside the scope.

Can a company be liable under the TCPA for calls made by a third-party telemarketer?

Yes, under agency principles. The FCC has ruled that a seller may be vicariously liable under the TCPA for calls placed on its behalf by third-party marketers under federal common-law agency theories — actual authority, apparent authority, or ratification — even though the seller did not physically dial the calls. Plaintiffs in TCPA class actions routinely allege that the brand being marketed controlled or accepted the benefits of the calling campaign; whether an agency relationship actually existed is a fact question in each case.

Is a company liable for the acts of an independent contractor?

Generally no — respondeat superior applies to employees, not independent contractors, which is one reason worker classification is fought over so intensely. But the rule has significant exceptions: a hiring party can be liable where it retains control over the manner of the work, where the work involves non-delegable duties or is inherently dangerous, where the contractor acts with apparent authority, or where the 'contractor' is actually a misclassified employee under the applicable legal test.

How is vicarious liability different from negligent hiring or supervision?

Vicarious liability is imputed: the employer is responsible for the employee's tort even though the employer itself did nothing wrong. Negligent hiring, retention, and supervision are direct claims: the employer's own carelessness — hiring someone with known red flags, ignoring complaints, failing to supervise — is the wrong. The two are often pleaded together, and direct claims matter most where the underlying act falls outside the scope of employment, where respondeat superior would not reach.
