In common law, duty refers to a requirement to perform a certain action that is mandated by law, custom, or morality. This obligation often creates a right in another person for the duty to be fulfilled, and a breach of such duty can result in legal consequences. For example, a doctor has a duty of care towards their patients, which means they are required to provide the best possible treatment. If they fail to do so, they can be held liable for medical malpractice. The concept of duty in common law also extends to landowners, who have a duty of care to those on their premises, and businesses, where managers have a duty of care in their decision-making and supervisory functions.

|---|---|
| Definition | Duty refers to a requirement to perform some conduct that is demanded by law, custom, morality, or personal commitment. |
| Duty of care | At common law, duties were formerly limited to those with whom one was in privity one way or another. In the early 20th century, judges began to recognize that enforcing the privity requirement had harsh results in many product liability cases. |
| General duty of care | The idea of a general duty of care that runs to all who could be foreseeably affected by one's conduct first appeared in the judgment of William Brett (later Lord Esher), Master of the Rolls, in Heaven v Pender (1883). |
| Specific circumstances | There are significant differences among common law jurisdictions concerning the specific circumstances under which that duty of care exists. |
| Reasonable limit | Courts cannot impose unlimited liability and hold everyone liable for everyone else's problems. There must be some reasonable limit to the duty of care. |
| Landowners | In the case of landowners, the extent of their duty of care to those who came on their premises varied depending on whether a person was classified as a trespasser, licensee, or invitee. |
| Statutory duty | A statute must clearly specify the conduct or duty required, who is required to undertake the conduct or perform the duty, and what qualifies as a breach of that duty. |
| Class of persons/class of harm | The legislature was trying to protect car accident victims from further injury that might be caused by oncoming traffic. |
| No excuse | There must be a lack of excuse on the defendant's part for their behavior. |
| Public duty doctrine | The public duty doctrine does not apply in tort cases where a plaintiff’s claim is based on a common law duty as opposed to a statutory duty. |

Duty of care
Duty, in the context of common law, refers to a legal obligation to perform a certain action, and a failure to do so can result in legal consequences. Duty of care, in particular, is not always defined by law but often develops through the jurisprudence of common law. It is the requirement to act with reasonable care to refrain from causing foreseeable harm in interactions with others. For example, a doctor has a duty of care towards their patients, which means they are required to provide the best possible care. If they fail to do so, they can be held liable for medical malpractice.
In the context of landowners, the extent of their duty of care to those who came onto their premises varied depending on whether a person was classified as a trespasser, licensee, or invitee. This rule was eventually abolished in some common law jurisdictions. For instance, the Colorado Premises Liability Act of 1986 enacted a statutory version of the common law classifications and displaced all common law remedies against landowners to prevent state courts from expanding their liability. In the Republic of Ireland, under the Occupiers' Liability Act of 1995, the duty of care to trespassers, visitors, and "recreational users" can be restricted by the occupier, provided reasonable notice is given.
In product liability cases, the idea of a general duty of care towards all those who could be foreseeably affected by one's conduct emerged in the 19th century. This implied that manufacturers had a duty of care to end users, even if they were several parties removed from the original manufacturer. Similarly, in Scots and English law, a manufacturer who sells a product in a form that will reach the ultimate consumer with no intermediate examination owes a duty of care to that consumer.
In the context of tort law, the public duty doctrine has been interpreted to mean that government entities are subject to the same tort liability as private entities. This doctrine does not apply when the alleged breach is based on common law duties rather than statutory duties. For example, in Norg v. City of Seattle (2023), the Court ruled that the public duty doctrine did not apply when the plaintiff's claim was based on a common law duty of care, and the city was found to have breached its duty by failing to take reasonable care.

Landowner duty
In common law, the duty of care owed by landowners to those entering their land is based on a classification system. This classification is based on the benefit provided to the landowner by the entrant. The categories are trespassers, licensees, and invitees. Invitees are owed the highest standard of care, as they are on the land for the benefit of the landowner. Invitees include business invitees, who enter the land for a purpose connected with the premises, and public invitees, who are invited to enter or remain on the land for a purpose for which the land is held open to the public.
Landowners must make the land reasonably safe for invitees and warn them about potential dangers. They must also notify licensees of hidden dangers and may need to repair dangerous conditions for them. The lowest duty of care is owed to adult trespassers, to whom landowners generally do not owe a duty of care. However, landowners may not intentionally injure trespassers, and if frequent trespassers are known, they must be warned of any dangers, especially those that are unlikely to be discovered.
Landowners owe child trespassers a greater duty of care under the "attractive nuisance doctrine," which requires landowners to take reasonable measures to protect children from artificial conditions that may lure them into danger. Some jurisdictions have moved away from the classification system towards a more general duty of care owed by the landowner. This system is based on a duty of reasonable care for foreseeable risks.
Landowners also owe a duty to those outside their land, such as refraining from activities that may cause harm to people or property outside their land.

Duty to rescue
Exceptions to the Rule
Some common law jurisdictions have created statutes that mandate a general duty to rescue under certain conditions. For example, in Yania v. Bigan, a 1959 Pennsylvania Supreme Court case, the court found that strip-mine operators who encouraged a visitor to jump into a deep body of water had a duty to rescue the visitor when he jumped and drowned. In Zelenko v. Gimbel Bros., Inc., a 1935 New York State case, shop owners who began rendering medical assistance to an ill customer but then left her alone for many hours were found liable for her death under a standard of negligence.
Certain U.S. states have modified the common law aversion to creating a duty to rescue. For example, Minnesota law states that "a person at the scene of an emergency who knows that another person is exposed to or has suffered grave physical harm shall, to the extent that the person can do so without danger or peril to self or others, give reasonable assistance to the exposed person." Similarly, in Ontario, Canada, a person who voluntarily provides assistance during an emergency without expecting compensation is generally not liable for damages unless gross negligence is established.
Ethical Justifications
There are ethical justifications for role-specific or skill-specific duties of rescue. These justifications are rooted in the idea that the best rescues are done by those with special skills. For example, firefighters are trained to safely evacuate people from burning buildings, and healthcare professionals such as physicians, nurses, and EMTs are equipped to provide medical rescue. In such cases, the ethical argument for a duty to rescue is stronger, as these skilled professionals can maximise the good more effectively than a regular stranger.
Civil Law Systems
Civil law systems, common in Continental Europe, Latin America, and much of Africa, impose a far more extensive duty to rescue. This duty is usually limited to doing what is "reasonable," without substantially endangering oneself. For example, after a traffic accident that causes injury, other drivers and passers-by must help or summon emergency assistance if they can do so without endangering themselves.

Duty and negligence
In common law, the concept of duty is integral to understanding negligence. Negligence refers to the failure to act with a reasonable level of care that a prudent person would typically exercise under similar circumstances. This can include both actions and omissions, where the omission of an action is considered negligent when there is a duty to act, such as a duty to prevent harm arising from one's previous conduct.
The determination of negligence often involves assessing whether a legal duty was owed by the defendant to the plaintiff, and if this duty was breached. This duty of care is a general principle that holds individuals and entities accountable for their actions and their potential impact on others. The existence of a duty of care depends on various factors and can arise from different relationships and situations.
For example, certain relationships, such as business owner-customer, doctor-patient, or manufacturer-consumer, inherently create a duty of care. In these cases, the defendant has a responsibility to act reasonably and avoid causing harm to the plaintiff. This duty of care is not unlimited and is shaped by the specific circumstances of each case, including the foreseeability of harm and the potential severity of any resulting injury.
To establish negligence, the plaintiff must typically prove that the defendant breached the duty of care by failing to meet the standard of a reasonable person in similar circumstances. This standard can vary depending on the specific facts of the case and the nature of the relationship between the parties involved. The plaintiff must also demonstrate that the breach of duty directly caused them harm, considering any intervening factors that may have contributed to the harm.
The concept of "negligence per se" arises when a defendant's violation of a criminal statute is used as evidence of their breach of a civil duty. In such cases, the plaintiff must prove that the statutory duty was clear and specific, outlining the required conduct, the responsible party, and the consequences of any breach. This concept highlights the interplay between criminal and civil law in establishing negligence and the breach of a duty of care.

Duty and tort law
In common law, the concept of duty is integral to understanding tort law. A duty of care, though not always defined by law, often develops through the jurisprudence of common law. This duty of care is owed by a party to those who could be foreseeably affected by their conduct. For instance, in the context of product liability, a manufacturer owes a duty of care to consumers to ensure their products are reasonably safe. This duty extends to all those in the distribution chain, including sellers. Similarly, in the case of landowners, their duty of care to those entering their premises varied depending on whether the person was a trespasser, licensee, or invitee.
Tort law deals with civil wrongs, aiming to compensate victims for their losses rather than punish the wrongdoer. While tort law varies across states, many courts refer to the Restatement of Torts as a guide. Torts can be categorised as intentional, negligent, or strict liability torts. Intentional torts refer to wrongs the defendant knew or should have known would result from their actions or omissions. Negligent torts occur when the defendant's actions are unreasonably unsafe. Strict liability torts, such as product liability, focus on the harm or result rather than the degree of care exhibited by the defendant.
The duty concept is also relevant in tort defences, such as self-defence against intentional torts. In New York State (NYS), for example, a person generally has a duty to retreat or leave a situation instead of using physical force in self-defence, except when defending their home. Additionally, government officials may be immune to certain lawsuits under the doctrine of sovereign immunity, which varies between states.
Furthermore, tort law intersects with criminal law in some cases, such as battery, which can be addressed through both criminal and tort law. In such instances, tort law provides monetary compensation to the plaintiff, while criminal law focuses on rehabilitating the defendant and benefiting society. Additionally, torts can be distinguished from contract law, as a breach of contract is typically not considered a tortious act.
