Robert Sparks, Petitioner v. Lorie Davis, Director, Texas Department of Criminal Justice, Correctional Institutions Division

1. Does cross-examination of a prosecution’s expert cure all harm from that expert’s repeated false testimony during a capital punishment proceeding, and is the petitioner or prosecution at fault for failing to correct the expert’s false testimony? 2. Did the Circuit Court Err by failing to consider whether Bailiff Moorehead’s actions created an unacceptable risk of impermissible factors coming into play at Sparks’ trial, and does Brecht’s “substantial and injurious effect or influence” standard of harm apply to impartial jury claims?
