(plaintiff was a potato farmer that insured his crops under an insurance policy written by the Federal Crop Insurance Corporation; plaintiff obtained insurance from defendant insurer after discussing options with two of defendant’s agents; when insurer denied coverage after plaintiff suffered a loss caused by adverse weather conditions, plaintiff filed a breach of contract , negligence, and estoppel action against the insurer and its agents; defendants sought to remove action to federal court, arguing that the claims were controlled by the Federal Crop Insurance Act (FCIA); in granting plaintiff’s motion to remand, court ruled that removal was appropriate only where state law claims were subject to “complete preemption”; the FCIA did not completely pre-empt state law claims; as such, the court lacked subject matter jurisdiction to hear the claims).
