Negligence Flashcards
Rule statement for negligence
Negligence is carelessness. In order to determine liability, the plaintiff must prove, by a preponderance of the evidence, that the defendant owed a legal duty to the plaintiff, which the defendant breached, and the breach was both the factual cause and proximate cause of the plaintiff’s damages.
General rule statement for duty
At first, there was no duty. However, over time, policy changes led to the idea that a general duty exists upon everyone not to act carelessly so as to harm another. More specifically, duty is an obligation, based on special relationship between the parties or a relationship imposed by law, that one person will not place the other in risk of foreseeable and unreasonable harm.
General rule statement for breach
Once a duty is established, the plaintiff must prove that the defendant breached that duty. A breach is a defendant’s failure to exercise reasonable care through nonconformance with the applicable standard of care.
Duty
Failure to Act
Generally, there is no duty and no liability for a failure to act.
Duty
Exceptions to failure to act (6)
- Relationship to victim: family; carriers, innkeepers, utilities; custody; employment; property ownership
- Relationship to tortfeasor: children; mental health patients
- Entrustment of dangerous instrumentalities
- Involvement in the accident
- Voluntary assumption of duty
- Statutory duties
Duty
Duty to aid others in emergency
Generally, there is no duty at common law to warn, protect, or rescue a stranger where the defendant is not at fault
Duty
Duty to aid others in emergency found (6)
- Special relationship between defendant and victim
- Defendant induces reliance or interferes with other rescuers
- Defendant aused the plaintiff’s injury
- Statutes may impose duty
- Special relationship between defendant and harmer
- Where defendant has understaken aid to the plaintiff
Duty
If the defendant voluntarily undertakes to aid the plaintiff . . .
The defendant must exercise due care. The defendant can abandon her efforts, but the condition in which she may leave the plaintiff varies based on jurisdiction (no worse, no comparable peril, or no imminent peril of serious bodily harm). Many states exempt physicians who render aid in an emergency from negligence liability.
Duty
Duty to protect and control
There is no duty to control a third person to prevent him from causing harm to another unless (a) a special relationship exists between the defendant and the third person which imposes a duty to control the third person’s conduct or (b) a special relationship exists between the defendant and the other which gives the other a right to protection.
Breach
5 ways a plaintiff can prove the defendant failed to use reasonable care
- Common sense (reasonable, prudent person)
- Balancing of costs and benefits (hand formula)
- Custom
- Negligence per se
- Res Ipsa Loquitor
Breach
Negligene may be proven by . . .
direct or circumstantial evidence. Direct evidence is evidence of the fact in question while circumstantialevidence is evidence from which the fact in question may be inferred.
Breach
Notice requirement
Notice is only required if a dangerous condition is out of the ordinary. If the defendant’s mode of operation makes injury otherwise foreseeable, the failure to take precautions may give rise to liability, even in the absence of notice of specific conditions which caused harm to the plaintiff.
Breach
Actual notice
Actual notice is when the defendant is explicitly informed of the risk of harm.
Breach
Constructive notice
Constructive notice is established by evidence that the danger existed so long that it should have been discovered through the exercise of reasonable care.
Breach
Spoliation
The information is in the hands of the defendant. They are required to maintain the information for a specific period of time. Generally, courts will handle spoliation through sanctions. However, in cases of spoliation by a third-party, there is a stronger case for recognizing spoliation as an independent cause of action.
Breach
Reasonable, prudent person
Once a duty is established, breach can be determined if the person that owes the duty fails to act as a reasonable, prudent person would under the circumstances. The reasonable, prudent person is neither super cautious, nor inattentive to risks.
Breach
Emergency & reasonable, prudent person standard
The existence of an emergency does not change the standard of care, but is a factor bearing upon whether a defendant acted reasonably, unless the defendant created the emergency.
Breach
Physical handicap/intoxication & reasonable, prudent person standard
A person with a physical handicap is expected to act as a reasonable, prudent person with the same handicap would. There are generally no allowances for voluntary intoxication, but involuntary intoxication is held to the same standard as physical handicap.
Breach
Religious beliefs & reasonable, prudent person standard
A person’s religious beliefs are a relevant factor in determining whether that person acted reasonably, but do not change the standard of care.
Breach
Children/age & reasonable, prudent person standard
The standard of care for a child is measured by the degree of care which would ordinarily be observed by children of the same age, intelligence, and experience under similar circumstances. Children are held to an adult standard when they engage in adult activities that are inherently dangerous. Generally, children 5 year and under are not liable for negligence.
Breach
Mental deficiency & reasonable, prudent person standard
Generally, metnal deficiency does not excuse a person from liability for conduct which does not conform to the standard of a reasonable, prudent person under the circumstances, unless the mental state is so low the person lacks the capacity to understand a danger exists. Mental deficiency is always relevant to the issue of contributory negligence.
Breach
Superior knowledge, training, or skill & reasonable, prudent person standard
If the actor is a member of a profession, the standard of care will be defiend with reference to that group. The actor will be found negligence for failing to perform with the degree of knowledge, skill and diligence of an ordinary, minimally competent member of that profession.
Breach
Race, gender, ethnicity & reasonable, prudent person
The majority rule is that an actor’s race, gender, or ethnicity does not change the standard of care or is even a relevant circumstance in determining whether ordinary care was exercised.
Breach
Judge-made standards of care
The conduct of a reasonable person may also be established by judicial decision without reliance on legislation. This somtimes yields inflexible results.
Breach
Hand formula
Once a duty is established, courts may employ a negligence balancing test to determine if the defendant’s conduct is unreasonable. The hand formula provides that if the burden on the defendant to prevent the risk is less than the probability the event will occur combined with the magnitude of the loss, the defendant will be liable.
B<PxL
Breach
Custom
Custom does not determine the standard of care (except for doctors). Conformance with custom raises a rebuttable inference of reasonableness. Departure from custom raises a rebuttable inference of unreasonableness.
Breach
Custom exception
An exception to custom raising an inference of reasonableness arises in cases where the custom is negligent as a matter of law.
Breach
Negligence established by statute
A statute defines the standard of care if the legislature says it does or the court nevertheless says it does.
Breach
Negligence Per Se
Negligence per se leads to a conclusive finding of negligence if the plaintiff can prove that the defendant, without excuse, violated a criminal statute that is designed to protect against the type of harm caused by the defendant and the plaintiff is wihtin the class of persons to be protected.
Breach
Excusable violations of statutes (negligence per se)
In majority jurisdictions, a violation only raises a preumption of negligence which the defendant can rebut with evidence of an adequate excuse or reasonable care. If rebutted properly, the jury may disregard the violation as evidence of negligence.
Breach
Excuses for statute violations (6)
- Violation is reasonable in light of the defendant’s childhood or physical diability/incapacitation
- The defendant exercised reasonable care in attempting to comply with the statute
- The defendant does not know nor should know of the factual circumstances that render the statute applicable
- Violation is due to the confusing way in which the statute’s requirements are explained
- Where it was safer, under the circumstances, to disobey
- Other excuses worthy of recognition
Breach
Not excuses for violation of statute (3)
- An actor’s personal opinion that the statute is excessive or unwise
- Ignorance of the law
- People customarily violate the law
Breach
Compliance with statute
Compliance with a statute does not necessarily establish that a defendant acted reasonably. If the situation is more hazardous than usual, precautions beyond the statutory minimum may be required.
Breach
Statutes allowing no excuse or defense
Certain types of statutes are commonly interpreted to permit no excuse, imposing a form of strict liability. If laibility is imposed under this theory, no excuse is permitted and thus comparative fault and assumption of the risk are not available.
Breach
Special standards of care
Courts have sometimes attempted to implement degrees of negligence through gradations: slight, ordinary, and gross. These are typically avoided because they are impractical in application because they are highly fact-specific, time consuming, and subject to dispute. They are rarely employed, except in connection with bailments, common carriers, innkeepers, and utilities, and some statutes.
Breach
Res ipsa loquitor: type of evidence and when used
Res ipsa loquitor (“the thing speaks for itself”) allows a plaintiff to use circumstantial evidence to prove negligence, a duty and a breach, and recover. It is used in situations where there are no witnesses or the witnesses aren’t talking.
Breach
Res ipsa loquitor: reason for doctrine
One of the reasons for res ipsa loquitor is cases in which the defendants are in control of all of the evidence.
Breach
Res ipsa loquitor: rule statement
The plaintiff must prove that the incident would not normally occur without someone’s negligence; that the incident was of a type that the defendant had a duty to guard against; the instrumentality causing the injury was under the defendant’s exclusive control; and that neither the plaintiff nor any third party contributed to or caused the plaintiff’s injuries.
Breach
Res ipsa loquitor: exclusive control
Control is not a rigid requirement. All that is required is that the instrumentality is under the defendant’s control at the time the injury occurred, not necessarily that the defendant was in possession of the instrumentality.
Breach
Res ipsa loquitor: greater access to information
It is not necessary that the defendant possess superior knowledge or superior opportunity to obtain knowledge of how the injury occurred. However, it is often present in res ipsa loquitor cases as evidence of negligence where companies have greater knowledge of and access to information regarding hazards or risks and potential contributors to such risks.
Breach
Res ipsa loquitor: rebuttal evidence
In cases in which the plaintiff asserts res ipsa loquitor, the defendant often respons by producing evidence that due care was in fact exercised. If the defendant’s evidence does not prove such, the plaintiff is entitled to a reasonable inference of negligence.
Breach
Res ipsa loquitor: multiple defendants
Res ipsa loquitor may be used if there are multuple defendants and it would be unreasonable to expect the plaintiff, due to no fault of their own, to be able to identify which defendant caused the harm. The defendant must stand in special relationship to each other and that all had responsibility for the plaintiff’s safety. The doctrine typically will not apply in cases where the defendants are strangers to one another. Many cases in non-medical scenarios have required the key test of whether the defendants had joint control over what caused the injury.
Legal Malpractice
Duty
An attorney owes a duty of care to anyone who becomes a client. The duty of care extends as far as the scope of representation. Limited obligations may arise to prosective clients, third-party beneficiaries, or nonclients who would reasonably rely on the attorney.
Legal Malpractice
Breach
A lawyer, because of her superior knowledge and professional experience, is held to a higher standard of care, that is ,to act as a reasonable, prudent and minimally competent lawyer of the same state would under the circumstances. The standard of care is reasonableness, not good faith. Liability is imposed only if the defendant did what no attorney could do or failed to do what every attorney must do. Expert witnesses from the same state would need to testify as to the state standard.
Legal Malpractice
Exercise of discretion
There is no liability for exercise of discretion, including reasonable errors of judgment, failure to predict the resolution of unsettled questions, failure to question well-settled law, or reasonable failure to assert a novel topic.
Medical Malpractice
Duty
For a claim of medical malpractice, the plaintiff must prove that a doctor/patient relationship was establishe, such as proving there was an in-person, physical examination.
Medical Malpractice
Breach
A physician, because of her superior knowledge and professional experience, is held to a higher standard of care, that is, to act as a reasonable, prudent, and minimally competent physician within the United States would under the circumstances.
Medical Malpractice
Proving breach
For physicians, custom is dispositive. Breach of standard of care is usually only provable by expert testimony to establish the threshold at which the physician failed to act properly or the adoption, however skillfully administered, of the wrong method. If the breach is so obvious that a lay person could easily determine there has been a breach, expert testimony is not required.
Medical Malpractice
Informed consent: broadly
The doctrine of informed consent requires an adequate disclosure of risks to a patient. The failure to obtain informed consent is professional negligence, even if the treatment is skillfully rendered.
Medical Malpractice
Informed consent: rule statement
The plaintiff must prove that the doctor did not disclose all material risks and/or treatment alternatives that a reasonable, prudent, miniminally competent doctor would have disclosed under the circusmtances and in accordance with the recognized standard of acceptable professional practices, which will likely require expert testimony to establish.
Medical Malpractice
Informed consent: material risk
A material risk is anything that might change a plaintiff’s decision in whether or not to undergo the treatment. The plaintiff must show that a reasonable, prudent person probably would have declied the treatment had there been full disclosure.
Medical Malpractice
Informed consent: exceptions (3)
- If the information is, or should be, known to the patient
- Disclosure would be detrimental to the patient’s best interest
- There is an emergency and the plaintiff cannot give consent
Factual cause
Factual cause: general rule
Once the plaintiff has shown that the defendant has acted negligently, he/she must prove that the negligence was the factual cause of the injury and resulting damages.
Factual cause
But for test
The plaintiff must show that but for the defendant’s negligence, the injury would not have occurred. There can be multiple but for causes for an event.
Factual cause
Substantial factor test
If the plaintiff sustains an injury as the result of the negligent conduct of two or more tortfeasors, and it appears that the conduct of either one alone would have been sufficient to cause the injury, both are liable if each of their acts was a substantial factor in causing the injury.
Factual cause
Substantial factor?
A substantial factor is one which multiplies the odds of the incident occurring from possible to probable.
Factual cause
Concurrent causes test
Where the separate negligent acts of the defendant and a party concur to cause a single injury, and it appears that the plaintiff would not have been injured but for the concurrence, then both defendants are actual causes and jointly liable.
Factual cause
Loss of chance
Loss of chance is the loss of ability to secure a correct diagnosis and earlier treatment which might have extended the patient’s life. The plaintiff must prove that the physician’s negligence caused the plaintiff’s likelihood of achieving a more favorable outcome to be diminished.
Factual cause
Formula for loss of chance
(1) Total amount of damages allowed under wrongful death statute; (2) % chance of survival prior to malpractice; (3) % chance of survival after malpractice; (4) subtract (3) from (2); multiple (4) by (1)
Factual cause
Multiple fault and alternative liability
Where a plaintiff cannot show whether one of two defendants’ negligence was the actual cause of the injuries, the burden of proof shifts to the defendant to show his/her negligence was not the actual cause. If the defendants cannot decide amongst themselves who is liable, they will be held jointly liable.
Factual cause
Market share laibility: broad applications
Market share liability is a limited liability theory and, in the vast majority, only applies to fungible goods.
Factual cause
Market share liability: requirements (4)
- All named defendants are potential tortfeasors
- Alleged products of all tortfeasors are identical
- Plaintiff, through no fault of her own, cannot identify which defendant caused the injury
- Defendants represent a substantial share of the market. (each defendant is liable for damages representing only its share of the market at the relevant time)
Factual cause
California market share
The burden shifts to the defendants if the number sued is sufficiently substantial to prevent injustice. Defendants may exculpate themselves by proving they did not make the particular item in question.
Factual cause
New York market share
Defendant who engaged in a particular type of conduct is liable even if it neither caused the plaintiff’s harm nor acted in concert with the one who did. Enforced a national market measure.
Factual cause
Enterprise liability
Enterprise liability requires that multiple manufacturers cooperated in the production and design of a faulty product based on an industry-wide standard. The buden shifts to the defendants if they jointly controlled the risk and it is virtually certain that the responsible party is in court.
Factual cause
Concerted action liability: broad, general rule
A concerted actoin is a common plan or design to commit, aid, or otherwise further a tortious act.
Factual cause
Concerted action liability: rule statement
A person is subject to liability for harm resulting to a third person from the tortious conduct of another if the person (1) commits a tortious conduct as a part of a common scheme or design with the other; (2) gives substantial assistance to the other knowing that the other’s is a breach of duty; or (3) gives substantial assistance to the other to accomplish a tortious result while also acting in a manner that is a breach of duty to the third person.
Factual cause
Concerted action: common scheme or design
Some level of knowledge or awareness of pertinent attendant circumstances is required. The focus is on the defendant’s knowledge of the conditions that resulted in harm to the plaintiff. Merely acting in concert is not enough if the plan or scheme itself is not tortious, unless there is knowledge of some aspect of circumstances that creates a foreseeable risk.
Factual cause
Concerted action: aiding and abetting
Aiding and abetting is providing substantial assistance or encouragement to someone committing a tortious act
Factual cause
Concerted action: civil conspiracy
Civil conspiracy is an agreement to act together and requires intent to accomplish an unlawful purpose or a lawful purpose by unlawful means
Proximate cause
Proximate cause: general rule statement
After proving factual causation, the plaintiff must prove that the defendant was the proximate cause, or legal cause, of the harm. The question is whether the harm to the plaintiff was so remote, so unforeseeable, so bizarre that holding the defendant liable is unfair.
Proximate cause
Foreseeability: rule statement
A defendant is generally only liable for consequences qhich are reasonably foreseeable. Foreseeability focuses on whether the defendant should have reasonably foreseen, as a risk of her conduct, the general type of harm suffered by the plaintiff. However, the result must be within the risk created by the defendant’s conduct and foreseeability is not sufficient to create liability if the harm is too tenuous and remote.
Proximate cause
Intervening cause
An intervening cause is a new force which joins with the defendant’s conduct to cause the plaintiff’s injuries. An intervening cause can be human, animal, mechanical, or natural. If the defendant should have foreseen the possibility that the cause might occur or the type of harm was foreseeable, the defendant’s conduct is nonetheless the proximate cause.
Proximate cause
Superseding intervening cause
The defendant is relieved from liability if there is a superseding intervening cause. [Intervening cause]. An intervening cause is considered superseding only when unforeseeable and its occurrence appears extraordinary under the circumstances. If the intervening cause is foreseeable, liability is still superseded if the defendant’s conduct in no way increases the likelihood of the harm occurring.
Proximate cause
Must be foreseen (3)
- General class of persons
- General type of harm
- Only a remote possibility of harm
Proximate cause
Does not have to be foreseen (3)
- Exact maner of harm
- Full extent of harm
- Ordinary rescue measures
Proximate cause
Pure economic loss
In general, there is no liability for negligent interferences with economic interests.
Proximate cause
Exceptions to pure economic loss rule
- Where negligence relates to legal or accounting malpractice
- Misrepresentation
- Failure to settle an insurance claim within policy limits
- Spoliation of evidence
- Breach of fiduciary duty
Proximate cause
Criminal or intentionally tortious acts as intervening causes
An intentional tort or a criminal act will cut off foreseeability and will relieve the liability of the tortfeasor, except where the intentional tort and criminal act is in fact forseeable.
Proximate cause
Rescue doctrine
Danger invites rescue. Rescue is presumed reasonably foreseeable, and the defendant is liable for any injury to a rescuer, so long as the rescue was not undertaken carelessly. The rescue doctrine requires imminent peril, an act of intervention, and an underlying tortious conduct by the defendant.
Proximate cause
Rescue: Peril created by victim
The rescue doctrine applies where the peril has been created by the victim
Proximate cause
Rescue: liability for losses when?
The doctrine governs liability for losses subsequent to intervention.
