Conflict preemption compliance with both federal and state regulations is a physical impossibility, or, where state law stands as an obstacle to the accomplishment and execution of the full purposes and objectives of congress.
Preemption is simply defined as the right of ownership to something.
Conflict preemption has to do with the tussle between advocates of state's right when there is a conflict about interpretation of the law based on the execution of the law.
Because of this, preemption is unpopular between advocates of a state's right as it is difficult for one party to concede the rights to purchase.
