Can a superseding cause break the chain of causation and defeat my claim?

· 3 min read

A later event can sometimes cut off a defendant’s responsibility, but Georgia law sets a high bar before that happens. The question is whether the intervening event was so independent and unforeseeable that it, rather than the defendant’s original carelessness, became the true legal cause of the harm.

How Georgia separates a mere intervening act from a superseding one

Not every event that occurs between the defendant’s conduct and the injury breaks the causal chain. Georgia distinguishes an ordinary intervening act, which leaves the original wrongdoer on the hook, from a superseding cause, which relieves that wrongdoer of liability. The dividing line is foreseeability. If the later event was a reasonably foreseeable consequence of the defendant’s negligence, the defendant generally remains liable even though something else also contributed. Only when the intervening act is a separate, unforeseeable force that the defendant could not reasonably have anticipated does it qualify as superseding and become the sole proximate cause.

Courts often describe the superseding event as one that is independent of the original negligence and sufficient by itself to produce the result. A defendant raising this defense is essentially arguing that the connection between the original act and the injury is too remote to support fault.

Why most intervening events do not defeat a claim

Because foreseeability is judged generously toward the injured party, many events a defendant points to fail to qualify. A few principles tend to control:

  • Ordinary medical treatment, including a complication that flows from injuries the defendant caused, is usually treated as foreseeable rather than superseding.
  • The negligent acts of a third party can be foreseeable when the defendant’s conduct created the very risk that the third party would act carelessly.
  • The injured person’s own predictable reactions to a dangerous situation generally do not break the chain.

Whether an event was foreseeable is normally a question for the jury, not something a court decides as a matter of law, except in plain and undisputed cases. That means a superseding-cause argument frequently survives only to the point of letting the jury weigh it.

It is also worth separating this defense from comparative fault. If the injured person’s own conduct contributed, Georgia’s apportionment rule under O.C.G.A. § 51-12-33 scales the recovery down by that share and cuts it off once the share hits half, but that operates on a different track from a superseding cause that severs liability outright.

The bottom line

A superseding cause can defeat a Georgia claim, but only when an independent, unforeseeable event becomes the real legal cause of the injury. Foreseeable complications, predictable third-party conduct, and ordinary follow-on events usually keep the original defendant responsible, and in close cases the jury decides whether the chain of causation held.
