Causation is the legal link between a wrongful act and the harm a person suffers. In a negligence case, it is not enough to show that someone behaved carelessly. The careless conduct must be connected to the injury. Causation is the element that establishes that connection.
This guide explains how causation works under Georgia law, the two forms of causation Georgia recognizes, and the concepts that limit how far legal responsibility extends. It is general educational information about how the law works, not advice about any particular case.
Causation Within a Negligence Claim
In Georgia, a negligence claim has four elements: a duty of care owed to the injured party, a breach of that duty, a causal connection between the breach and the resulting harm, and damages. Causation is the third element, and it is often the most heavily contested.
A defendant may have clearly acted carelessly, and the plaintiff may clearly be injured, yet the claim still fails if the carelessness did not cause the injury. Georgia courts treat causation as a real and separate hurdle, not a formality. The injured party generally carries the burden of proving causation by a preponderance of the evidence.
The Two Forms of Causation
Georgia law divides causation into two distinct concepts that both must be satisfied: cause in fact and proximate cause.
Cause in fact, also called actual cause, asks whether the defendant’s conduct actually produced the injury as a matter of physical fact. Georgia courts commonly apply the but-for test. The question is whether the injury would have occurred but for the defendant’s conduct. If the harm would have happened anyway, even without the defendant’s negligence, then the defendant’s conduct was not the cause in fact.
Proximate cause, also called legal cause, asks a different question. Even when conduct is a cause in fact, the law does not hold a defendant responsible for every remote or unforeseeable consequence that can be traced back to it. Proximate cause limits liability to harms that are the natural and probable consequence of the negligent act and that a reasonable person could have foreseen. Georgia courts describe the inquiry as whether the harm was a reasonably foreseeable result of the conduct.
Both forms must be present. A defendant whose conduct was a cause in fact but not a proximate cause is generally not liable, and a defendant whose conduct was foreseeably dangerous but did not actually produce the injury is also not liable.
Foreseeability and the Limits of Liability
Foreseeability is central to proximate cause in Georgia. The law draws a line between consequences that are within the reasonably anticipated risk of the conduct and consequences that are too remote.
Georgia courts have long recognized that the determination of proximate cause depends on the particular facts of each case. There is no fixed formula. A jury, applying the foreseeability standard, decides whether the connection between the wrongful act and the injury is close enough to support liability. In some cases the connection is so clear, or so plainly absent, that a court can decide proximate cause as a matter of law, but in most cases it is a question for the jury.
O.C.G.A. § 51-12-9 reflects this concern with remoteness. It provides that when damages are too remote to be the natural and proximate consequence of a wrong, they are not recoverable. The statute confirms that Georgia law ties recovery to a genuine, non-remote causal connection.
Intervening and Superseding Causes
A recurring causation issue is what happens when something occurs between the defendant’s conduct and the plaintiff’s injury. Such an event is called an intervening cause.
Under Georgia law, an intervening cause can break the chain of causation and relieve the original wrongdoer of liability. This is sometimes called a superseding cause. However, an intervening cause does not automatically cut off liability. Georgia courts have held that if the intervening act and its consequences could have been reasonably foreseen by the original wrongdoer, the chain of causation is not broken, and the original defendant may still be liable.
The key question is again foreseeability. An intervening event that a reasonable person could have anticipated does not necessarily relieve the original defendant. An intervening event that is genuinely unforeseeable and independent is more likely to be treated as a superseding cause that ends the original defendant’s responsibility.
Concurrent Causes
Causation does not require that the defendant’s conduct be the only cause of the harm. Georgia law recognizes that an injury can have more than one proximate cause.
When two or more separate acts of negligence combine to produce a single injury, each may be a proximate cause. The fact that another person also contributed to the harm does not, by itself, excuse a defendant whose negligence was also a proximate cause. This principle connects causation to Georgia’s apportionment framework under O.C.G.A. § 51-12-33, which allows a jury to assign percentages of fault among multiple responsible parties.
Proving Causation
Causation must be proven with evidence, not speculation. Georgia courts have stated that the causal connection between the wrongful act and the injury must be established by evidence, whether through direct testimony or the opinion of qualified experts, and must not rest on conjecture or guesswork.
In cases involving medical questions, such as whether an accident caused a particular physical condition, expert testimony is often necessary. A jury generally cannot infer a medical cause from common experience alone when the question requires specialized knowledge. In simpler cases, the causal connection may be obvious enough that lay testimony is sufficient. Whether expert proof is required depends on the nature of the injury and the complexity of the causal question.
Summary
Causation is the element that connects wrongful conduct to harm in a Georgia negligence case. It has two parts: cause in fact, tested by the but-for inquiry, and proximate cause, governed by foreseeability and the limits on remote consequences reflected in O.C.G.A. § 51-12-9. Intervening events may or may not break the causal chain depending on whether they were foreseeable, and a single injury may have several concurrent proximate causes. Because causation must be proven with real evidence rather than guesswork, it often becomes the decisive issue in a negligence dispute.
