Although its ruling rejected any constitutional right to DNA testing by prisoners, a U.S. Supreme Court decision on Thursday is not expected to drastically affect efforts by inmates across the country to challenge their convictions through genetic testing thanks to the existence of individual state laws. The high court’s ruling in District Attorney’s Office for the Third Judicial District v. Osborne mostly impacted the exoneration attempts of a man in Alaska, William G. Osborne, who was convicted in 1994 of kidnapping and sexually assaulting a prostitute in Anchorage. The ruling majority, consisting of Chief Justice John Roberts Jr. and Justices Samuel Alito Jr., Anthony Kennedy, Clarence Thomas and Antonin Scalia, found no reason “to suddenly constitutionalize this area,” wrote Roberts.
