Causation
In every personal injury case, the injured party must prove more than just the fact that they were hurt. To recover compensation under Colorado law, the plaintiff must show that the defendant’s actions were not only negligent but also the cause of their injuries. This legal requirement is known as causation, and it is one of the most contested elements in many personal injury claims.
Understanding how causation works in Colorado personal injury cases is essential to building a strong legal argument, especially when the defense tries to shift blame or deny responsibility altogether.
What Is Causation in a Personal Injury Case?
Causation refers to the connection between the defendant’s conduct and the plaintiff’s injury. It is not enough to prove that the defendant acted negligently—there must be evidence that the negligence directly caused or contributed to the harm the plaintiff suffered.
Colorado courts recognize two key components of causation:
- Cause in fact (also known as “actual cause”): The injury would not have occurred “but for” the defendant’s actions.
- Proximate cause (also known as “legal cause”): The harm was a foreseeable result of the defendant’s conduct.
Both elements must be present for a plaintiff to recover damages. If either is missing or challenged successfully, the case can fail, even if the injury is serious.
Examples of Causation in Personal Injury Claims
The concept of causation applies to nearly every type of personal injury case.
Some common scenarios include:
- A distracted driver rear-ends another vehicle, causing whiplash and a herniated disc. The driver’s inattention is both the actual and proximate cause of the injury.
- A store owner fails to clean a spill, leading to a customer’s slip and fall. The owner’s failure to maintain the premises is the cause of the customer’s broken wrist.
- A construction site lacks proper barriers, resulting in a pedestrian being struck by falling debris. The absence of safety measures is the cause of the injury.
In each of these cases, the connection between the defendant’s negligence and the plaintiff’s injuries must be clear and supported by evidence.
How Is Causation Proven in Colorado?
To prove causation, plaintiffs must present evidence that links the defendant’s actions to the resulting injury.
This may include:
- Medical records documenting the injury and how it occurred
- Expert testimony from doctors or accident reconstruction specialists
- Eyewitness statements describing the incident
- Photos or video footage from the accident scene
- Incident reports from police, first responders, or property owners
Causation can be straightforward in some cases, such as when a driver admits fault at the scene. But in many instances—especially those involving complex injuries, multiple parties, or pre-existing conditions—the defense may argue that something else caused the harm.
Challenges to Causation in Injury Cases
Defense attorneys often target causation to avoid or reduce liability.
Common tactics include:
- Arguing the injury was pre-existing: Claiming the plaintiff already had the condition before the accident.
- Pointing to an intervening cause: Blaming a third party or an unrelated event for the injury.
- Disputing medical evidence: Challenging the connection between the incident and the current symptoms.
Even if the defendant’s negligence is obvious, these arguments can weaken a case if not rebutted effectively with expert analysis and thorough documentation.
Causation and Comparative Fault in Colorado
Colorado uses a modified comparative negligence rule with a 50% bar.
This means:
- You can still recover damages if you are less than 50% at fault.
- Your total compensation will be reduced by your percentage of fault.
- If you are 50% or more at fault, you cannot recover damages.
Causation plays a role here, too. If the defense can successfully argue that your actions were a major contributing cause of your own injuries, your recovery may be reduced or eliminated entirely.
Why Causation Matters in Settlement and Trial
Causation is often one of the most heavily litigated issues in personal injury cases, particularly those involving:
- Traumatic brain injuries
- Soft tissue injuries
- Delayed-onset symptoms
- Medical malpractice claims
- Accidents involving multiple liable parties
Insurance companies and defense attorneys will often try to break the chain of causation to avoid full payment. Proving a clear, direct connection between the defendant’s negligence and your injury helps strengthen your negotiating position and improve your chances at trial.
