What can be done if a specific case has no applicable statute?

Many issues have no statute to provide a resolution. When that happens, the trier of fact (judge or jury) must look to previous cases for guidance in coming to a decision. The higher the court that made a previous decision, the greater the weight the current court gives the ruling. So a decision from the U.S. Supreme Court has precedence over rulings from all other courts while a decision from a local or county court will only be considered by other courts at that level.
