Proximate cause is the legal idea that a defendant is liable only for harms that are closely enough connected to the wrongful conduct.
Why It Matters
This concept matters because not every consequence of a careless or wrongful act leads to legal liability. Courts use proximate cause to place reasonable limits on how far responsibility should extend.
Where It Appears
Proximate cause appears in negligence cases, personal injury disputes, and other tort claims where a plaintiff must connect the defendant’s conduct to the injury in a legally meaningful way.
Practical Example
A careless driver causes a crash that directly injures another motorist. That immediate injury is much more likely to satisfy proximate cause than a distant and unusual chain of later events.
How It Differs From Nearby Terms
Causation in fact asks whether the harm would have happened without the defendant’s conduct. Proximate cause asks whether the connection is close enough for legal responsibility. Duty of care is different because it concerns whether the defendant owed an obligation in the first place.
