Key Takeaways
- Failure to act occurs when a person or entity has a legal duty to take action but fails to do so, which can result in civil or criminal liability.
- Legal obligations to act often arise from special relationships (e.g., doctor-patient, employer-employee) or statutory duties (e.g., mandated reporting laws).
- Negligence by omission can be established if there is a duty of care, a breach of that duty, causation, and damages.
- Good Samaritan Laws in some jurisdictions protect those who provide voluntary assistance but may also impose a duty to act in emergencies.
- Corporate and governmental responsibilities can lead to large-scale consequences, such as infrastructure failures due to negligence or underinvestment.
- Failure to act in business law can include breaches of fiduciary duty, contract violations, and regulatory non-compliance.
- Possible defenses to failure-to-act claims include lack of duty, lack of foreseeability, and intervening causes.
A failure to act definition is when a person or party has a duty to perform a certain act but does not end up doing so.
A duty to act, within the scope of personal injury law or tort cases, generally refers to one of two things:
- People have a duty to act in a manner as to not cause direct harm to others. Should an individual fail to do so, then he or she may be liable for negligence.
- People are not necessarily obligated to intervene when they see someone else doing harm. Even though someone may say that they will do something, words alone are often not enough to bring on a duty to act.
As humans, we have two obligations towards our fellows: acting in accordance with the law, which is known as statutory duties, and moral duties, which are not legally upheld. Moral duties are considered the act of a good citizen and might include breaking up a fight or reporting a child or animal locked in a hot car. This is also known as a common law duty.
To establish a prima facie case for negligence, there are four elements that must exist:
- The existence of a legal obligation owed by one party to another
- Proof of breach of the aforementioned duty
- Proof that the wronged party (also known as the plaintiff) suffered an injury
- Evidence that it was the acts of the defendant that caused the plaintiff’s injury
Generally, within the scope of personal injury law, the negligent conduct involves some sort of action, such as a motorist hitting a cyclist or pedestrian with a car. With that said, inaction can also be considered negligent behavior, thus failure to act. An example of this may be if you are a teacher, nurse, social worker, or other vocation that is considered to be a mandated reporter, and you fail to report a case of domestic violence, sexual assault, or child abuse.
Additionally, a business owner may be liable for negligence (failure to act) if he refuses to make repairs to what could reasonably be considered a hazardous work environment, such as faulty elevator or a staircase that is falling apart.
Legal Consequences of Failure to Act
Failing to act when legally required can lead to both civil and criminal consequences, depending on the circumstances:
- Civil Liability: In cases involving personal injury, breach of duty, or financial harm, the responsible party may be required to compensate the victim for losses.
- Criminal Charges: If the failure to act results in serious harm, criminal charges such as manslaughter (e.g., failing to report child abuse) may be filed.
- Professional Disciplinary Actions: Doctors, lawyers, and other professionals may face disciplinary action, including license suspension, if they fail to fulfill their duties.
The severity of consequences depends on factors such as intent, duty owed, and the resulting harm.
Failure to Act and Legal Responsibilities in Different Contexts
Failure to act can have consequences in multiple areas of law, including personal injury, contract law, and business law. Some of the most common contexts in which a failure to act results in legal action include:
-
Personal Injury and Negligence:
- If a property owner fails to remove a hazardous condition, such as a wet floor, and someone is injured, they may be held liable.
- Employers who fail to implement workplace safety regulations can be held responsible for workplace injuries.
-
Medical Malpractice:
- A doctor failing to diagnose a patient’s illness when a reasonable medical professional would have done so may be liable for malpractice.
- Nurses or hospital staff failing to provide necessary emergency care may also be held responsible.
-
Contract Law:
- When a party to a contract fails to perform an agreed-upon duty, it may be considered a breach of contract.
- Businesses that fail to deliver goods or services as promised could face lawsuits.
-
Government and Infrastructure:
- A government's failure to maintain roads, bridges, or water supplies can lead to large-scale harm and economic consequences.
- Public agencies may be liable for failing to enforce safety regulations that result in injury or environmental harm.
-
Fiduciary Duty Violations:
- Corporate executives, financial advisors, or trustees may be liable for failing to act in the best interests of clients, shareholders, or beneficiaries.
Additional Information
Most criminal cases have two types of elements at play. First, there is men's rea, which means that there was intent to commit a crime. There is then actus rea, which lacks the burden of intent, although a crime was still committed. If you watch “Law & Order,” you may know the difference between homicide and manslaughter; manslaughter generally lacks intent (think a car accident in which someone was killed), making it actus rea. However, homicide is against the law, as is reckless driving.
While moral duties are not necessarily able to be legally upheld, in some cases, laws change to better reflect the morals of society. Examples of this are changes in laws regarding marital rape, meaning that a husband cannot forcibly engage in sexual relations with his wife unless she consents.
In some countries, such as France, there exist Good Samaritan Laws, which may hold you in failure to act, should you, for example, come across a parent hurting their child, and you do nothing to stop it.
As you prepare to review your insurance claim or speak with a personal injury attorney, it is important to understand the specifics involved with failure to act, negligence, statutory duties, and common law duties.
Defenses Against Failure to Act Claims
A defendant in a failure-to-act case may have several legal defenses, including:
- No Legal Duty: If there was no legal obligation to act, a failure to intervene cannot constitute negligence or wrongdoing.
- Unforeseeable Harm: If the harm was not foreseeable, a defendant may argue they could not have reasonably taken action to prevent it.
- Intervening Causes: If another party's actions were the direct cause of the harm, the defendant may not be held responsible.
Understanding the nuances of duty and liability can help individuals and businesses protect themselves from failure-to-act claims.
Exceptions
As with most things, there are some exceptions where there may not otherwise be a duty to act. For example, if you come across an injured person, while you are not obligated to assist them, should you begin doing so, then you are obligated to continue helping them or stay with them until medical assistance arrives; you cannot just then abandon the person.
Additionally, if you in some way, encourage someone to commit a crime which injures people in the process, then you may be held responsible for those injuries, even if you were not directly involved in causing them. The Mafia could be a good example of this; if you are a boss who orders a hit, then you can be ultimately held responsible, even though you are not the one who committed the act.
