18.1 Intentional Infliction of Emotional Distress

Key Takeaways

  • IIED requires extreme and outrageous conduct, intent or recklessness as to causing distress, causation, and severe emotional distress.
  • Conduct is extreme and outrageous where it exceeds all bounds tolerated in a civilised society, and mere insults, indignities, or annoyances do not qualify.
  • Ordinary conduct can become outrageous where the defendant abuses a position of authority, targets a known vulnerable plaintiff such as a child or pregnant woman, or exploits a known sensitivity.
  • The distress must be severe, and unlike the other intentional torts IIED requires actual damages, with no nominal recovery available.
  • Transferred intent does not apply to IIED, so a bystander plaintiff must generally be present, be a close relative of the victim, and have their presence known to the defendant, or else prove bodily harm resulting from the distress.

Intentional Infliction of Emotional Distress

Exam Snapshot: Emotional distress torts appear frequently on the California First-Year Law Students' Examination (FYLSE). The examiners routinely test the sharp doctrinal boundaries between Intentional Infliction of Emotional Distress (IIED) and Negligent Infliction of Emotional Distress (NIED). Examinees must master two recurring testing pivots: (1) the mental state requirement (IIED permits recklessness, which distinguishes it from all other intentional torts, whereas NIED requires negligence), and (2) the damage thresholds (IIED requires severe distress without requiring physical symptoms, whereas traditional NIED demands objective physical manifestation). Furthermore, bystander recovery rules under both torts feature strict multi-element tests designed to prevent fraudulent or unlimited claims.


1. Intentional Infliction of Emotional Distress (IIED)

Historically, the common law refused to recognize standalone claims for mental anguish unless the emotional suffering accompanied an independent, established physical tort (known as "parasitic damages" appended to battery, assault, or false imprisonment). During the mid-twentieth century, the American Law Institute formulated Intentional Infliction of Emotional Distress to bridge this gap, establishing a cause of action for purely psychic injury caused by intolerable misconduct (Restatement (Second) of Torts § 46).

Prima Facie Elements of IIED

To establish a prima facie cause of action for IIED, the plaintiff must prove four distinct legal elements by a preponderance of the evidence:

[ Extreme & Outrageous Conduct ] + [ Intent or Recklessness ] + [ Causation ] + [ Severe Emotional Distress ] = IIED Liability
ElementCommon Law Definition & Legal BenchmarkBar Exam Traps & Nuances
1. Outrageous ConductConduct so extreme in degree as to go beyond all possible bounds of decency, regarded as atrocious and utterly intolerable in a civilized community.Mere insults, bad manners, profanities, name-calling, and petty indignities are insufficient as a matter of law.
2. Mental StateThe actor acted with the specific desire to cause severe emotional distress, knew with substantial certainty that it would result, or acted with reckless disregard of a high risk of causing distress.Recklessness satisfies IIED. It is the only intentional tort on the FYLSE where conscious disregard of a high risk substitutes for purpose or substantial certainty.
3. CausationThe defendant's conduct was the actual (but-for) and proximate cause of the plaintiff's distress.Pre-existing emotional distress must be aggravated or superseded by defendant's specific acts.
4. Severe DistressEmotional distress of such substantial quantity and enduring quality that no reasonable person in a civilized society could be expected to endure it.Physical symptoms or bodily harm are NOT required for IIED at common law (unlike traditional NIED).

Doctrinal Breakdown: Extreme & Outrageous Conduct

The core battleground in an IIED claim is whether the defendant's behavior crosses the high legal threshold of "extreme and outrageous." The standard is purely objective: would an average member of the community, upon hearing the facts, exclaim, "Outrageous!" (Restatement (Second) of Torts § 46, comment d).

The Rule of Non-Actionable Insults

The law expects citizens to have reasonably thick skins. Liability never attaches for mere insults, bad manners, hurtful slurs, offensive name-calling, petty oppressions, or trivial indignities alone. Even if the speaker acts with malicious subjective intent to wound the plaintiff's feelings, offensive speech without more is legally non-actionable.

Four Aggravating Factors That Transform Conduct into Outrageousness

Conduct that would otherwise be classified as mere insults or ordinary dispute can become actionable outrageous conduct if one or more recognized aggravating factors are present:

  1. Abuse of a Position of Power or Authority: When the defendant occupies a position of legal, economic, or custodial leverage over the plaintiff and abuses that authority to intimidate, demean, or coerce the victim. Recognized relationships include:
    • Landlords harassing vulnerable tenants to coerce illegal self-help evictions;
    • Employers engaging in sustained, humiliating workplace hazing or predatory coercion;
    • Creditors and commercial debt collection agencies utilizing abusive, threatening, late-night collection tactics;
    • Police officers or security guards abusing badge authority to terrorize citizens.
  2. Exploitation of Known Vulnerability: If the defendant possesses actual knowledge that the plaintiff suffers from a specific, peculiar susceptibility or fragility—such as advanced age, young childhood, pregnancy, or a diagnosed cardiac or psychiatric disorder—and deliberately targets or exploits that vulnerability, conduct that is otherwise ordinary becomes extreme and outrageous.
  3. Continuous, Repetitive Conduct: A single isolated insult or offensive remark is non-actionable. However, continuous, repetitive harassment conducted over weeks or months (such as stalking, repeated midnight hang-up calls, or relentless public ridicule) crosses the threshold into actionable outrageousness.
  4. Special Status Defendants (Common Carriers & Innkeepers): Common carriers (airlines, passenger trains, municipal transit) and commercial innkeepers (hotels, motels) owe a special public utility duty to their patrons. In traditional jurisdictions, common carriers and innkeepers are liable for gross, unprovoked insults directed at paying passengers or guests, even if the conduct falls short of extreme and outrageousness required for private citizens.

The Damage Element: Severe Emotional Distress

To recover, the plaintiff must prove that the emotional distress suffered was severe:

  • Intensity and Duration: The distress must be substantial, debilitating, and enduring rather than transient or minor (e.g., profound depression, disabling panic attacks, chronic insomnia, inability to work or engage in daily life activities, necessity of psychiatric medical intervention).
  • Physical Manifestation Not Required: A critical bar examination rule: bodily harm or objective physical symptoms are NOT required to sustain an IIED action. While evidence of physical symptoms (e.g., ulcers, vomiting, weight loss) is admissible to corroborate the severity of distress, psychic suffering alone satisfies the damage element.

Bystander Recovery for IIED (Conduct Directed at a Third Party)

When an actor directs extreme and outrageous conduct at a third party (such as brutally assaulting or murdering someone in the presence of others), a bystander who witnesses the event can recover for IIED only under strict Restatement rules (Restatement (Second) of Torts § 46(2)):

Defendant Directs Outrageous Conduct at Third Party
├── Category A: Plaintiff is an Immediate Family Member
│   ├── Must be present at the scene at the time of the conduct; AND
│   ├── Defendant must have actual knowledge of plaintiff's presence; AND
│   └── Plaintiff suffers severe emotional distress (NO bodily harm required).
└── Category B: Plaintiff is a Non-Relative Bystander
    ├── Must be present at the scene at the time of the conduct; AND
    ├── Defendant must have actual knowledge of plaintiff's presence; AND
    └── Plaintiff must suffer severe emotional distress that RESULTS IN BODILY HARM.

Exam Tip: On the FYLSE, verify whether the defendant had actual knowledge of the bystander's presence. If a defendant beats a husband to death in an alleyway, unaware that the victim's wife is hiding silently behind a dumpster fifty feet away, the wife cannot recover for bystander IIED because the defendant lacked knowledge of her presence, defeating the required mental state of intent or recklessness toward her.

Emotional Distress Liability Pathways: IIED vs. NIED
Test Your Knowledge

A commercial landlord who wants to evict an elderly tenant who has lived in an apartment for thirty years knows that the tenant has a severe cardiac condition and is under doctor's orders to avoid emotional shock. To force the tenant out without filing an eviction action, the landlord arranges for the tenant's apartment water and electricity to be shut off repeatedly during cold winter nights, repeatedly bangs on the tenant's door at 3:00 a.m. shouting vulgar profanities, and falsely claims that the building has been condemned and the police will arrive in hours to throw the tenant into the street. The tenant suffers intense, debilitating fright, profound anxiety, and sleeplessness, and seeks psychiatric counseling, but suffers no heart attack or other physical bodily injury. The tenant sues the landlord for intentional infliction of emotional distress (IIED). Will the tenant prevail?
