Jason Edward Thomas Cardiff v. United States District Court for the Central District of California, et al.

This case presents the question whether a federal court may continue to rely on a record generated by a court-appointed officer in a pending criminal prosecution while declining to determine whether the officer committed fraud on the court in creating that record.

1. Whether allegations that a court-appointed officer committed fraud on the court by submitting false materials to a federal court present a judicial question that must be adjudicated by the court under its inherent authority to protect the integrity of judicial proceedings, rather than deferred to the ultimate factfinder as an ordinary evidentiary dispute.

2. Whether postconviction review constitutes an adequate alternative remedy where the alleged fraud was committed by a deceased court-appointed officer and no later proceeding can reliably reconstruct the provenance, authenticity, alteration, transmission, or judicial use of the challenged materials.
