Shady Grove Orthopedic Associates, P.A., provided medical care to Sonia E. Galvez for injuries she suffered in an automobile accident. As partial payment for that care, Galvez assigned to Shady Grove her rights to insurance benefits under a policy issued in New York by Allstate Insurance Co. Shady Grove tendered a claim for the assigned benefits to Allstate, which under New York law had 30 days to pay the claim or deny it. Allstate apparently paid, but not on time, and it refused to pay the statutory interest that accrued on the overdue benefits at two percent per month.
Shady Grove filed this diversity suit in the Eastern District of New York to recover the unpaid statutory interest. Alleging that Allstate routinely refuses to pay interest on overdue benefits, Shady Grove sought relief on behalf of itself and a class of all others to whom Allstate owes interest. The individual claim was worth roughly $500, which fell far short of the amount-in-controversy requirement for individual suits under 28 U.S.C. § 1332(a).
The District Court dismissed the suit for lack of jurisdiction. It reasoned that N.Y. Civ. Prac. Law Ann. § 901(b), which precludes a suit to recover a penalty from proceeding as a class action, applies in diversity suits in federal court despite Federal Rule of Civil Procedure 23. Concluding that statutory interest is a penalty under New York law, it held that § 901(b) prohibited the proposed class action.
