When someone is injured through the fault of another, they have a right to seek compensation. Sometimes the issue of liability, also called fault, is clear, such as a rear-end automobile accident. Other times the liability issue may be contested. The classic "green light/red light" case comes to mind. Both motorists can claim they had the right of way and if that case goes to trial, a jury decides the outcome of the dispute. In those cases, independent witnesses can be extremely helpful.
The amount of compensation to which an injury victim is entitled depends upon a multitude of factors. There are economic damages - medical expenses and lost wages - as well as compensation for what the injury victim has had and will continue to go through for the remainder of their life. The skill of the trial lawyer is extremely important in securing a fair and just award for an accident victim.
