Motion to compel
A motion asking the court to order a party to provide discovery it has wrongfully withheld.
A motion to compel asks the court to order an opposing party to respond to discovery — answer interrogatories, produce documents, or appear for a deposition — that it has failed or refused to provide. Under the Federal Rules it generally must be preceded by a good-faith meet and confer.
If granted, the court may also award the reasonable expenses, including attorney's fees, caused by the failure to provide discovery.
