Marquez v. Commissioner of Correction
Annotate this Case
The Supreme Court affirmed the judgment of the Appellate Court affirming the judgment of the habeas court denying Petitioner’s habeas petition, holding that the State did not violate the due process of Petitioner by not disclosing an alleged agreement between the State and a testifying accomplice in Petitioner’s underlying criminal case and by failing to correct the accomplice’s allegedly false testimony that no such agreement existed.
On appeal, Petitioner asked the Supreme Court to conclude, contrary to the determination of the lower courts, that the State had an agreement with the accomplice that it had not disclosed in violation of Brady v. Maryland, 373 U.S. 83 (1963) and that the nondisclosure of this agreement was material. The Supreme Court affirmed on the alternative basis that, even assuming that the State had no undisclosed deal with the accomplice, there was no reasonable likelihood that disclosure of the agreement would have affected the judgment of the jury. Therefore, the lack of any disclosure was immaterial under Brady and there was no due process violation.
