"District courts have authority both under common law and [Federal Rule of Civil Procedure] 54 (b) to reconsider interlocutory orders and to reopen any part of a case before entry of final judgment."

Traditionally, courts will find justification for reconsidering interlocutory orders when there is (1) an intervening change of controlling law;(2) new evidence available; or (3) a need to correct a clear error or prevent manifest injustice

Although the Federal Rules of Civil Procedure do not explicitly address motions for reconsideration of interlocutory orders, the authority for a district court to hear such motions is found in both the common law and in Rule 54 (b) of the Federal Rules of Civil Procedure.

Significantly, "justice does not require that the district court [grant reconsideration] on an issue that would not alter the district court's prior decision."
