OPINION OF THE COURT

Petitioners seek a writ of mandamus under the All Writs Act, 28 U.S.C. § 1651(a), directing the District Court to set aside its discovery order entered on October 31, 2012, and ordering certain discovery to be produced, namely expunged juvenile records. Further, they seek an order directing the District Court to permit their Carey v. Piphus, 435 U.S. 247, 98 S.Ct. 1042, 55 L.Ed.2d 252 (1977), defense.

Mandamus is a “drastic and extraordinary remed[y].... reserved for really extraordinary causes.” Ex parte Fahey, 332 U.S. 258, 259-60, 67 S.Ct. 1558, 91 L.Ed. 2041 (1947). It is well established that mandamus may only issue where (1) petitioners have “no other adequate means” to attain the relief they seek; (2) their right to mandamus is “clear and indisputable;” and (3) exercising discretion, we are satisfied that the mandamus “is appropriate under the circumstances.” In re Briscoe, 448 F.3d 201, 212 (3d Cir. 2006) (quoting Cheney v. United States Dist. Court, 542 U.S. 367, 380-81, 124 S.Ct. 2576, 159 L.Ed.2d 459, (2004)).

Petitioners have failed to satisfy these requirements. Petitioners have another appropriate avenue for relief — direct appeal after the entry of a final judgment. Hahnemann Univ. Hosp. v. Edgar, 74 F.3d 456, 461 (3d Cir. 1996). Mandamus may not be “used as a substitute for the regular appeals process.” Cheney, 542 U.S. at 380-81, 124 S.Ct. 2576. Petitioners are seeking just such a substitute here. 1

For the foregoing reasons, we decline to employ one of “the most potent weapons in the judicial arsenal,” id. at 380, 124 S.Ct. *109 2576, to address the parties’ contentions, and will deny the petition.
