The New Jersey Tort Claims Act grants sovereign immunity to public entities. That means, public entities can be at fault for certain things and still not be legally responsible. Of course, immunity has its limits. The NJ Tort Claims Act allows certain lawsuits to be filed under certain limited circumstances, but only when one follows all of the rules. One of the most common types of lawsuit allowed is when someone is injured on a dangerous condition of public property. This is when a claimant would need to file a timely notice of claim.
