ORDER AND JUDGMENT *

As the parties agree, the threshold issue before us is whether the Heck doctrine, see Heck v. Humphrey, 512 U.S. 477, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994), bars jurisdiction in this case. Whether Heck applies depends on whether deprivation of good-time or earned-time credits necessarily affects the duration of a Colorado prisoner’s confinement. The record is inadequate to resolve this matter, and both counsel at oral argument sought remand to the district court for development of the record. Accordingly, we REMAND to the district court for further proceedings concerning whether, under the Heck doctrine, the district court has jurisdiction to hear Mr. Baldaufs claims. If the court determines that it has jurisdiction, it should decide the merits, conducting any further proceedings that it deems necessary.
