The federal district judge will apply the state law while deciding the case.
State law refers to the separate law that each state has to be used or followed by the particular state. This means that one state's laws can differ from another state's laws, which is why each state makes laws of its own.
State laws give easier methods or processes to deal with accidents that may occur in a specific state. And in that regard, the state laws will be applicable for dealing with car accident cases, like in the case of Mary and Hanna.
