To successfully bring a Washington, D.C. personal injury case, a plaintiff must be able to prove not just that the defendant was negligent but also that the defendant’s negligence was the cause of their injuries. While the concept of causation may sound like a straightforward determination, in practice, the element can be exceedingly complex.
Causation can be broken down into two separate inquiries, the first being “but for” causation, or cause-in-fact. To satisfy the cause-in-fact element, the plaintiff must show that absent the defendant’s negligence, the accident would not have occurred. In most cases, cause-in-fact is not difficult to establish.
The second part of a causation inquiry is called proximate cause, or legal cause. Not only is proximate cause much more complicated, but it is also more challenging to prove. Proximate cause requires that a plaintiff prove that the defendant’s negligence and the plaintiff’s injuries are sufficiently related to say that the defendant’s actions were the legal cause of the plaintiff’s injuries.
