Rule 37 (a)(4)(A) targets motions to compel discovery. It awards reasonable expenses incurred, including attorney fees, not only when the court grants a motion to compel, but also if the opposing party provides the requested discovery after the motion to compel is filed. FRCP 37(a)(4)(A); Henry, 983 F.2d at 947. An award of expenses is mandated unless the motion to compel was filed without 'first making a good faith effort to obtain the disclosure of discovery without court action,' the 'nondisclosure, response, or objection was substantially justified,' or 'other circumstances make an award of expenses unjust.' FRCP 37(a)(4)(A).
