Proving Causation in Challenging Personal Injury Cases

In every personal injury case the plaintiff must be able to prove that the defendant’s actions (or inactions) was the legal (or “proximate”) cause of the plaintiff’s injuries. Causation is always an issue, even if it is relatively simple. Not every case is as straightforward as “A struck B and B was hurt.”

When connecting the dots from the defendant’s negligence to the plaintiff’s injury is not easy, the plaintiff’s attorneys must focus on establishing a strong case for causation. Tracing the consequences of a defendant’s negligence can be difficult for a number of reasons. That is because causation is complicated by a number of related factors:

  • Time. When time passes between a defendant’s negligent action and the resulting injury, showing causation can be more difficult. This is partly because important evidence can be lost to time, as physical evidence can be destroyed, memories can fade, and important witnesses cease to be available (for example, if a key employee of a business defendant is no longer working there).
  • Intervening causes. For a defendant to be held liable for an injury there must not be an intervening act of negligence that could also have caused the injury. Sometimes the plaintiff’s own negligence may have contributed to some or all of the damages suffered by the plaintiff. Other times another person’s wrongful actions were the real cause of the injury, but that person hasn’t been identified. The more time that has passed, the more likely the defendant will argue for intervening causes.
  • Scientific proof. Causation can require a highly technical analysis. The analysis may be of mechanical evidence, such as the failure of a product’s components. Or it may be medical, as in cases involving cancer or other illnesses that are slow to develop. When specialized knowledge is required to prove causation, the plaintiff’s team must make provision for it in their case if they hope to prevail.

Plaintiffs faced with complex causation challenges can overcome them using several approaches. The first is simply the process of uncovering evidence through discovery. In discovery both sides in the litigation ask for documents and conduct interviews (depositions) of individuals with knowledge about the facts of the case. Discovery often uncovers important facts that can be useful for establishing causation where it might otherwise remain hidden.

In many cases an expert witness can help the plaintiff provide technical analysis of the causal elements related to an injury. Experts are often invaluable in assisting judges and juries as they examine issues that require more than a commonsense understanding of the facts. Experts are hired by the plaintiff’s attorneys and their fees are typically taken out of the final award, but because their input can be decisive, they are often worth the expense.
