OPINION

David Lusick has filed a petition for a writ of mandamus, seeking that we order the United States District Court for the Eastern District of Pennsylvania to consider a complaint he says he filed on September 1, 2012 — a complaint that the District Court said it did not receive. 1 He also asks us to order that Court to serve and consider some of his other filings, and reassign a different judge to his District Court proceedings.

We will deny Lusick’s petition. Since the time Lusick filed his mandamus petition, he has complied with the District Court’s order to file a new complaint. The District Court has also randomly reassigned the proceedings to another judge. Thus, those requests are moot. We are confident that the District Court will also serve and/or consider Lusick’s other filings, to the extent it deems appropriate. If Lusick is unhappy with any of the District Court’s rulings, he can raise those issues on appeal. See Cheney v. U.S. Dist. Ct., 542 U.S. 367, 380-81, 124 S.Ct. 2576, 159 L.Ed.2d 459 (2004) (mandamus is not a substitute for appeal). 2
