In Michigan, there are legal limitations for suing a ski resort or ski operator for injuries that occur on the slopes. In most cases, there must be a hazard on ski slope itself that causes an injury. The fact that you were injured going downhill is not enough.
There are cases for skier vs skier injuries. This is when one skier is reckless and crashes into another skier causing a serious injury. The injured skier can sue the one that caused the crash and the homeowner’s insurance often pays a settlement.
