Notes on Negligence: Duty, Breach, Evidence, and Statutory Breach (RI L, Breach per se)

How We Figure Out If Someone Was Careless (Negligent Breach)

We're looking at negligence, which is when someone acts carelessly and causes harm. Our main focus here is on breach – meaning the defendant didn't act like a "reasonable person" would have. We use a few main methods to figure this out, especially when it's not obvious:

• "What's Normal?" (Custom): Did they follow standard practices for their job or industry?

• "Is It Worth It?" (Cost-Benefit Analysis / HENS-style thinking): Did the cost of taking a safety step outweigh the risk of harm if they didn't take it?

• "Things Speak for Themselves" (Res ipsa loquitur - RI L): Sometimes, an accident is so unusual that it just looks like someone had to be careless, even if we don't know exactly what happened.

• "Against the Rules!" (Breach per se / Negligence per se): If someone breaks a safety law, they're often automatically considered careless in a legal sense.

• Important Things to Remember:

  • Custom is strong evidence, but not the final word. Just because everyone does it doesn doesn't mean it's safe, and not doing it doesn't always mean you were careless.

  • Cost-Benefit Analysis is a good guide, but it's hard to put exact numbers on things like serious injury or death, so it's not a strict rule.

  • The HENS formula (which is a type of Cost-Benefit Analysis) is a helpful trick, but it struggles with severe harms because the numbers are too hard to pin down.

  • RI L and Breach per se are just ways to help prove carelessness; they don't automatically mean the defendant is responsible for all the harm or that they caused it.

• For Your Exams: Think about "Issue, Rule, Analysis, Conclusion" (IRAC) and break down big problems into smaller, clearer questions.

Quick Look: Duty and Breach

• Duty: What you should do, based on what a "reasonable person" would do to keep others safe.

• Breach: When your actions fall short of that "reasonable person" standard.

• These tools (Custom, CBA, RI L, Breach per se) help us figure out if a breach happened, especially when we don't have perfect evidence or when a law/custom points to a clear safety standard.

Tools to Prove Carelessness: A Closer Look

• "What's Normal?" (Custom)

  • If you follow the usual way of doing things, it suggests you were careful.

  • If you don't follow the usual way, it suggests you were careless.

  • Still, it's not a definite answer. Courts look at everything!

• "Is It Worth It?" (Cost-Benefit Analysis - CBA)

  • Goal: To see if someone should have spent money or effort on a safety step.

  • Good for: Shows how people logically think about safety.

  • Problem: It's often hard to get exact numbers for the cost of prevention versus the seriousness of potential harm. It's more of a general idea than a hard rule.

  • Restatement Third, Torts §3: Explains how reasonable people consider safety costs versus risks.

  • Judge Posner's idea: This tool works less well when the potential harm is very serious, like death.

  • Takeaway: CBA is one piece of the puzzle, not the whole answer, unless you have super clear numbers in a business deal.

• "Things Speak for Themselves" (Res ipsa loquitur - RI L)

  • This isn't a type of injury; it's a rule of evidence that helps you prove carelessness when you don't have direct proof.

  • Basic Idea: If an accident happens that usually doesn't happen without carelessness, and the defendant was in charge of what caused it, plus the injured person didn't cause it, then a jury can guess that the defendant was careless.

  • Direct evidence vs. Indirect evidence: Direct means you saw it (e.g., someone saw a barrel fall). Indirect means you have clues that let you figure out what happened (e.g., long skid marks tell you the car was going fast).

  • Big Challenge: RI L doesn't automatically prove carelessness; it just allows the jury to infer (guess) it. The judge decides if the jury can use RI L.

  • Three-Part Test (simplified):
    1) The event wouldn't normally happen unless someone was careless.
    2) The thing that caused the injury was controlled by the defendant.
    3) The injured person didn't do anything to cause their own injury.

  • Who Does What: The judge decides if RI L can even be considered. The jury then decides if they want to use it to infer carelessness.

  • "Exclusive Control": This doesn't always mean absolute control. Courts often accept it if it's highly likely the defendant was in charge.

  • Takeaway: RI L lets a jury use circumstantial evidence to decide if carelessness happened when there's no direct proof.

• "Against the Rules!" (Breach per se / Negligence per se)

  • Rule (from Restatement Third, Torts §14): You're considered careless if you, without good reason, break a law that was made to prevent the exact kind of accident that happened, and the hurt person was exactly who the law was trying to protect.

  • If someone proves all this, then the defendant is considered careless as a matter of law. But, the injured person still has to prove that this carelessness caused the harm and what their damages (losses) are.

  • Key Points:

    • The law itself sets the standard for carefulness.

    • Breaking that law leads to "breach per se" if the injured person is in the protected group and the accident matches what the law aimed to prevent.

    • This doesn't automatically mean the defendant caused the injury or owes money. Those are separate steps.

  • Takeaway: Breaking a safety law is a very strong way to show carelessness, but you still need to prove that the broken law actually led to the injury.

Direct vs. Indirect Evidence: Simple Terms

• Direct Evidence

  • Proof of a fact that you don't need to think about or guess (e.g., someone says they saw a barrel fall and hit someone, or they found a surgical pad that looks exactly like the ones used in that hospital).

  • It's only as good as the person giving the testimony.

• Indirect Evidence (Circumstantial Evidence)

  • You prove one fact, and from that fact, you can guess or infer another fact (e.g., long skid marks suggest speeding, but there might be other reasons; you have to put more clues together to be sure).

  • RI L uses this type of evidence to infer carelessness when you don't have direct proof of what went wrong.

• Takeaway: Both RI L and breach per se often use a mix of direct and indirect clues to help a jury decide if someone was careless.

Case examples: How these ideas are used

Burn v Bodle (Falling flour barrels)

• What Happened: A barrel fell from a flour dealer's window and hit someone. No one saw how it fell.

• Evidence: Witnesses saw the barrel fall. There was a cart (suggesting movement) nearby. The defendant was a flour dealer, so the barrels were theirs.

• Court's Decision: The court said the jury should have been allowed to use RI L (Things Speak for Themselves) to infer that the flour dealer was careless. Barrels don't usually just fall on their own from a shop window without someone being careless.

• Lesson: RI L is good for proving carelessness using indirect clues when direct evidence is missing. The defendant being in control of the barrel was key.

Combat v. Saint Francis (Surgical pads left inside)

• What Happened: After surgery, an 18-inch surgical pad was found inside a patient, leading to a fatal infection.

• Evidence: The pad was found, it matched the hospital's pads, and these pads are only used in surgery. The hospital said they followed procedures, but experts rejected the idea that the patient swallowed it.

• Court's Decision: The appellate court said the trial court should have told the jury about RI L. It's the kind of thing that doesn't usually happen without carelessness, and the hospital had control during surgery.

• Lesson: RI L can help when specific proof of carelessness in a complex setting (like surgery) is hard to get, allowing the jury to infer it.

Victor v. Hedges (Car parked on sidewalk)

• What Happened: A car was parked on a sidewalk during construction, breaking a local law against parking there. A pedestrian was injured.

• Arguments: The injured person said breaking the law (parking on the sidewalk) automatically meant the driver was careless (breach per se). The driver argued the law was meant to prevent cars blocking the sidewalk, not to make them responsible for every sidewalk injury.

• Court's Decision: The court said that breaking the law didn't automatically make the driver responsible in this specific case because it wasn't clear that parking the car there directly caused this injury. The court reminded everyone that the "reasonable person" standard is always there, even if "breach per se" doesn't fully apply.

• Lesson: Breach per se is powerful, but you still need to prove that breaking the law actually caused the injury.

Martin v Herzog (Carelessness vs. Causation)

• Lesson: This case reminds us that just because someone was careless (breach) doesn't automatically mean that carelessness caused the harm. These are two separate things to prove.

Tips for Figuring Things Out (and for Exams)

• When to Use Which Tool:

  • Use Custom if there's a clear industry standard and someone didn't follow it.

  • Use CBA if you have clear numbers for costs and risks; otherwise, treat it as a general idea.

  • Use RI L when you have an accident that strongly suggests carelessness but no direct proof, as long as the three-part test fits.

  • Use Breach per se when a safety law was broken, the law protects people like the injured person, and it was meant to prevent this type of accident. But always remember to prove it caused the harm!

• Important Cautions:

  • RI L isn't a guarantee; it just allows a jury to think about inferring carelessness, not forcing them to decide it.

  • Breach per se proves carelessness, but you still need to prove the carelessness caused the harm and what the damages are.

  • Always separate carelessness (breach) from causation. Breaking a rule doesn't automatically mean it caused the accident.

• Exam Strategy: Always start with the big question, then get more specific. Use IRAC (Issue, Rule, Analysis, Conclusion) to explain your logic clearly.

• Simple Math for Cost-Benefit (HENS-style):

  • Imagine the chance of harm is p and the possible loss is L. The expected cost of not taking a precaution is E = p \times L.

  • Example: If there's a 0.5% chance (p=0.005) of losing 300{,}000 (L=300{,}000), the expected cost is 0.005 \times 300{,}000 = 1{,}500.

  • General Rule: If the expected harm is more than the cost of a safety step, then taking that safety step is probably what a reasonable person would do. This is a guide, not a strict calculator.

• Why This Matters (Real-World & Ethics):

  • These ideas help us understand what a "reasonable person" should do.

  • They guide businesses and organizations to manage risks better, making things safer when costs and risks make sense.

  • Ethically, these rules push for responsibility and make sure people don't just rely on vague "common sense" without thinking clearly about safety.

Quick Summary: Important Cases

• Burn v Bodle (Falling barrel): Teaches that RI L helps juries guess carelessness when there's no direct proof, based on the three-part test.

• Combat v Saint Francis (Surgical pad left inside): Shows that judges must let juries consider RI L when the facts point to carelessness through indirect evidence.

• Victor v Hedges (Car on sidewalk): Reminds us that even if a law is broken (breach per se), you still need to prove it caused the injury. The "reasonable person" standard is always there.

• Martin v Herzog (Carelessness vs. Cause): Highlights that being careless is one thing; actually causing the injury is another.

In a Nutshell

We figure out if someone was careless (breach) using direct evidence (what we saw) and indirect evidence (clues), guided by these tools. Always refer back to what a "reasonable person" would do. Remember to clearly separate being careless, causing the harm, and the resulting damages in your thinking. Use RI L and breach per se when they fit, but know they are just tools to prove carelessness, not the whole story of who is responsible.
