The "New York Civil Law" blog discusses a recent Court decision dealing with the "serious injury" requirement in car accident cases.
For non-lawyers and lawyers who are not experienced with this issue, NY law says you can't get money in a car accident case unless you can show a "serious injury". There are a number of categories that qualify. The easy category is a fracture. If you have a broken bone, you're in. The four categories that lead to close calls are: significant limitation, permanent consequential limitation, permanent loss of use, and "90/180". What that means gets very complicated but it is the critical issue in many car accident cases.
