The Post-Conviction Bureau includes the Appellate Division, the Writs Division, and the Conviction Integrity Unit. Prosecutors in the Appellate Division represent the State on behalf of the District Attorney in all criminal cases that are appealed from the Harris County courts, in certain civil appeals of cases in which the Office has been involved, and any other related extraordinary legal proceedings that may arise in the appellate courts, such as writs of mandamus. Writs prosecutors, on the other hand, represent the State in felony and misdemeanor post-conviction writ cases in the Criminal District Courts, the County Criminal Courts at Law, and the Court of Criminal Appeals. Finally, the Conviction Integrity Unit is responsible for managing petitions for post-conviction DNA testing as well as the various disclosure issues that may require mass disclosures or inclusion in the recurring witness disclosure database.
