When a federal district court makes a determination regarding whether to quash or enforce a subpoena, that decision is subject to appeal at the circuit court level. A circuit court can review a district court’s decision either deferentially or de novo. If a circuit court engages in deferential review, it will only overturn a district court’s decision if it determines that the district court abused its discretion in the matter. On the other hand, if a circuit court engages in de novo review, it will assess the factual evidence of the case and make a legal determination without regard for the findings by the court below. McLane Company, Inc. argues that a circuit court hearing an appeal from a district court’s decision to quash an Equal Employment Opportunity Commission (“EEOC”) subpoena should review the decision below deferentially. The EEOC argues, however, that a circuit court in that situation should instead review the decision de novo. The outcome of this case will impact the course of future EEOC litigation.
