A snapshot on that date: matters listed may since have been decided or reassigned. A motion referred to a magistrate judge is counted for both judges. Motions in multidistrict litigation, section 2255 cases and Social Security appeals are not counted, and a very large three-year count is generally a multidistrict docket.

How long civil cases take in this court
For the whole of U.S. District Court for the Eastern District of Pennsylvania, not for Judge Perez: median time from filing to disposition of the civil cases the court closed in the 12 months ending September 30, 2025, as reported by the Administrative Office of the U.S. Courts.
| Cases | Median time | |
|---|---|---|
| All civil cases closed | 5,730 | 5.1 months |
| Closed with no court action | 1,952 | 3.2 months |
| Closed before pretrial | 2,834 | 4.7 months |
| Closed during or after pretrial | 898 | 10 months |
| Closed during trial | 46 | 17.8 months |
| 12 months ending | Cases closed | Median time |
|---|---|---|
| Sep 2025 | 5,730 | 5.1 months |
| Sep 2024 | 6,200 | 4.6 months |
| Sep 2023 | 6,595 | 7 months |

| Sep 2020 | 4,686 | 5.7 months |
| Sep 2019 | 5,374 | 6 months |
The table leaves out prisoner petitions, land condemnations, deportation reviews, recovery of overpayments and enforcement of judgments, and reports no median for fewer than 10 cases. A district that closed a large multidistrict litigation in the period shows very large counts and long medians for that year. Source: Table C-5, U.S. District Courts (spreadsheet).
