1. Respondeat Superior and Scope of Employment

Kind of work Was the employee doing the type of task hired to perform or an act reasonably incidental to it? Time and place Did the conduct occur substantially within authorized work time and space?

Purpose to serve Was the employee motivated, at least in part, to serve the employer? Foreseeable deviation A slight personal detour may remain within scope; a substantial frolic for purely personal ends usually does not.

The going-and-coming rule usually excludes ordinary commuting, but the outlines recognize exceptions where a work-created danger or special mission makes the trip sufficiently related to employment.

2. Contractors, Enterprises, and Immunity Rules

Employers generally are not vicariously liable for independent contractors because they do not control the manner of work. The exceptions focus on duties that cannot be avoided by delegation or on reasonable appearances that the contractor acts for the principal.

Issue General rule Important qualification

Independent contractor No ordinary vicarious liability. Possible liability for apparent authority, negligent selection or supervision, nondelegable duties, or inherently dangerous work.

Joint enterprise Members may answer for one another's torts. Usually requires common purpose, shared pecuniary interest, and equal right of control.

Family-car doctrine Some jurisdictions impose liability on an owner for family-purpose use with consent. The rule is jurisdiction-specific and depends on statutory or common-law formulation.

Workers' compensation Workplace injury is usually handled through the compensation system without proof of employer fault. Intentional employer torts may fall outside exclusivity.

Government Sovereign immunity applies unless waived. Waiver statutes, discretionary-function exclusions, public-duty rules, and proprietary operations determine exposure.

Family immunity Modern law often permits interspousal claims. Parental immunity may remain for negligent parenting or supervision but not independent duties or willful misconduct.

Key Takeaway

The outlines distinguish protected policy or discretionary decisions from routine implementation or ministerial acts. General police protection may be immune under the public-duty rule, while a specific undertaking and reliance can create a special duty.

Direct negligence remains separate

Even when vicarious liability fails, a plaintiff may allege the principal's own negligent hiring, supervision, entrustment, maintenance, or failure to perform a nondelegable duty.

Immunity must come from law

Do not infer immunity simply because a defendant is charitable, governmental, parental, or connected to employment. Identify the precise statute or doctrine and its exceptions.

3. Analyze Relationship Liability Step by Step

1 Prove the underlying tort committed by the employee, contractor, family member, or other actor. 2 Classify the relationship and identify the person from whom liability is sought. 3 Apply scope-of-employment, control, common-purpose, or consent requirements. 4 For an independent contractor, test apparent authority, nondelegable duty, and direct negligence. 5 If immunity is asserted, identify the source, protected function, and exceptions. 6 Separate vicarious liability from contribution, indemnity, and the principal's own negligence.

Key Takeaway

An employee driving between work sites stops briefly for coffee and negligently causes a crash while returning to the assigned route. A slight-deviation analysis asks about the purpose, duration, location, and foreseeability of the stop. If the deviation remains a detour rather than a frolic, the employer may be vicariously liable.

Common Mistake

Do not equate employment with automatic liability. The employee must act within the scope of employment, and the underlying tort must still be proved.

Primary Authorities

  • • Bussard v. Minimed, Inc. (work-related danger during commute).

  • • O'Shea v. Welch (slight deviation and scope of employment).

  • • Popovich v. Allina Health System (apparent authority).

  • • Maloney v. Rath (nondelegable duty).

  • • Riss v. City of New York and DeLong v. County of Erie (public duty and special relationship).

  • • Zellmer v. Zellmer (parental immunity for negligent supervision).

Exam-ready conclusion

Vicarious liability turns on relationship and scope; immunity turns on protected status and legal exceptions. Analyze each as a separate layer after establishing the underlying tort.
