OPINION OF THE COURT

Appellant Bruce Cooper was found guilty by a jury of second degree murder and robbery in 1985 and sentenced to a mandatory term of life imprisonment. His *126 direct appeal was dismissed by the Superi- or Court for failure to file a brief. In August 1988 he filed a state post-conviction petition and counsel was appointed to represent him. After several evidentiary hearings, the trial court denied the petition and the Superior Court affirmed. The Pennsylvania Supreme Court denied Cooper’s petition for allowance of appeal on July 12, 1996.

On June 11, 1998, almost two years later, Cooper filed a petition for writ of habeas corpus pursuant to 28 U.S.C. § 2254, in which he raised a juror misconduct claim, a claim that the prosecutor withheld exculpatory evidence, and a claim that counsel rendered ineffective assistance in violation of the Sixth Amendment in failing to present a competent defense and in failing to pursue a direct appeal. The District Attorney of Philadelphia answered the petition and raised the one-year statute of limitations defense under 28 U.S.C. § 2244(d)(1). The Magistrate Judge recommended that the petition be dismissed as time-barred, and the District Court agreed, adopting the Magistrate Judge’s report as the opinion of the court. The petition was denied by order entered on November 23, 1998 and Cooper appealed.

On June 9, 1999, we granted a certificate of appealability, and ordered the parties to show cause why the order should not be vacated and the matter summarily remanded for consideration of appellant’s equitable tolling arguments, as set forth in his reply to the respondent’s answer and his objections to the Report and Recommendation, in light of this Court’s decision in Miller v. New Jersey State Dep’t of Corrections, 145 F.3d 616 (3d Cir. 1998). Following the submission of responses, we appointed counsel to represent Cooper and the appeal proceeded to briefing.

We will vacate the order of the District Court, and remand the matter for further proceedings in accordance with Miller v. New Jersey State Dep’t of Corrections, 145 F.3d 616, 618 (3d Cir. 1998) (equitable tolling appropriate where principles of equity would make rigid application of habeas statute of limitations unfair). On remand the District Court should address Cooper’s argument that he was not aware of the decision denying his petition for allowance of appeal until September 1997, the copy of a letter from the state supreme court dated September 30, 1997 advising him that his petition had been denied on July 12, 1996, his argument that prison officials searched his cell and removed and destroyed legal materials relating to his criminal case which also delayed the filing of his habeas petition, and the grievance-related and other materials submitted in support of this argument.

The District Court appears to have overlooked these arguments, and we will not consider them, or the extensive rebuttal offered by the appellees (Appellees’ Brief, at 17 30), because they involve a mixed question of law and fact and are best addressed by the District Court in the first instance. See Meyers v. Gillis, 93 F.3d 1147, 1152 (3d Cir. 1996). We express no view on the merits of Cooper’s arguments.

We will vacate the order of the District Court entered on November 23, 1998, and remand the matter for further proceedings.
