Trespass to Land (Scope of License) * **Black Letter Law:** A trespass action will lie if a defendant enters land with permission (a license) but overstays the duration of the permission or fails to remove an object from the land after the license has expired. * **License Definition:** Permission/authority to enter upon the land of another. * **Key Case:** *Rogers* * **Facts:** Defendant had a license to place a snow fence on the decedent's land during winter but failed to remove the post after the season/license expired. The husband died when his mower struck the post. * **Holding:** The failure to remove the object after the license expired reverted the defendant to the status of a trespasser. ### 2. Trespass to Chattel vs. Conversion * **Black Letter Law:** * **Trespass to Chattel:** Requires either (1) some harm/damage to the chattel OR (2) dispossession of the chattel for a long enough period that the dispossession itself constitutes damage. * **Distinction from Conversion:** The difference is the **degree of interference**. * **Trespass to Chattel:** Shorter duration or less interference (e.g., taking a bike for an hour). * **Conversion:** substantial interference or total destruction (e.g., taking a bike for a month). * **Key Cases:** * *Liden* (1949): Statutory strict liability for dog bites existed unless the plaintiff was trespassing. The court found a child playing with a dog did not commit trespass to chattel because there was no harm to the dog and no dispossession. * *CompuServe v. Cyber Promotions* (1997): Defendant sent unsolicited spam email using CompuServe’s routers. The court held that electronic signals are sufficiently physically tangible to support a trespass cause of action, and damages were satisfied by "intermeddling" that interfered with the possessor's interest. * *Pearson v. Dodd:* Former employees removed files, copied them, and returned the originals. Court held this was **not conversion** because the documents were returned before the owner could use them, and the information was not proprietary property. *** # Affirmative Defenses to Intentional Torts **General Procedural Rule:** * Plaintiff must prove the prima facie elements of the tort (Case in Chief). Attacking the sufficiency of the plaintiff's case is *not* an affirmative defense. * If the plaintiff meets their burden, the burden shifts to the defendant to raise affirmative defenses. * **Legal Effect:** A valid affirmative defense is a **complete bar to recovery**. ### 1. Shopkeeper's Privilege * **Black Letter Law:** A shopkeeper is privileged to detain a person if three elements are met: 1. **Reasonable Belief:** There must be a reasonable belief as to the theft. 2. **Reasonable Manner:** The detention must be conducted in a reasonable manner, and **no deadly force** can be used. 3. **Reasonable Time:** The detention must be only for a reasonable period of time to complete the investigation. ### 2. Consent * **Black Letter Law:** Consent is a defense to intentional torts (e.g., Battery). * **Express Consent:** Exists where plaintiff has expressly submitted (written or oral) to defendant's conduct. * *Vitiation:* **Fraud** and **Duress** vitiate (nullify) consent. * **Implied Consent:** * **Apparent Consent:** Exists when a reasonable person would infer consent from the plaintiff's conduct. * **Consent Implied by Law:** Exists where action is necessary to save a person's life or an important interest in property (e.g., emergency surgery on an unconscious patient). * **Key Cases:** * *Hackbart (Cincinnati Bengals):* Players imply consent to conduct within the rules of the game (Apparent Consent) but do not consent to intentional blows/conduct outside the rules. * *O'Brien (1891):* Plaintiff stood in line and held out her arm for a vaccination. Court held this was **apparent consent** manifested by her conduct. * *De May v. Roberts (1881):* A man falsely claiming to be a doctor's assistant held a woman's hand during childbirth. Any implied consent was invalid because it was obtained through **fraud** regarding his identity/qualifications. ### 3. Self-Defense & Defense of Others * **Self-Defense Rule:** When a person has a reasonable belief that they are about to be attacked, they may use **reasonable force** for protection. * *Proportionality:* Force must be reasonable. Deadly force can only be used to counter deadly force. * **Defense of Others Rule:** One may use force to defend another person **only when the other person could have used force**. * *Standard:* The defender steps into the shoes of the victim. ### 4. Defense of Property * **Black Letter Law:** One may use reasonable force to prevent the **commission** of a tort against their property. * **Limitations:** * Force can only be used while the tort is in progress (hot pursuit). Once the tort is completed (e.g., thief has escaped), force is no longer privileged. * **Deadly force** can **never** be used solely to defend property. ### 5. Public Necessity * **Black Letter Law:** Where the act is for the public good, the defense is absolute. * **Damages:** Those whose property is destroyed by an act of public necessity will **not** have the right to recover. * **Examples:** Fire department smashing a car window to access a hydrant during a fire. Blowing up a house to create a firebreak during a city-wide conflagration. ### 6. Private Necessity * **Black Letter Law:** A defendant acting out of private necessity is relieved of the technical tort of trespass but **must compensate** the plaintiff for any actual damage done. * **Hypothetical:** A person seeks shelter under a stranger's porch during a severe lightning storm. * *Trespass:* The landowner cannot eject the person while the danger (storm) persists. * *Damages:* If the person breaks a vase or damages the floor while sheltering, they are liable for those damages. ### 7. Justification * **Black Letter Law:** A "catch-all" defense used when other defenses do not fit, but it would be unjust to hold the defendant liable. * **Elements:** Actions taken were reasonable and done to protect others from injury or to protect property. ### 8. Statute of Limitations * **Definition:** A specific time period within which a legal action must be filed. * **Nature:** It is an affirmative defense. A plaintiff can file a lawsuit after the period expires; the defendant must actively **raise** the statute of limitations defense. * **Legal Effect:** If valid, it is a complete bar to recovery. *** # Exam Writing Technique * **Structure:** 1. Identify Parties. 2. Identify Cause of Action (e.g., Battery). 3. State Rule. 4. Analysis (Apply facts to Prima Facie elements). 5. Conclusion. 6. **Affirmative Defenses:** Always address this section. If no defenses apply, explicitly state: "The facts do not give rise to any affirmative defenses".
