Writ of Coram Nobis A legal remedy, typically used in criminal cases, that allows a court to review and potentially correct a fundamental error in a previous judgment, if the error was not apparent at the time of trial. The defendant filed a writ of coram nobis arguing that newly discovered evidence proved his innocence. There are many historical examples of writs of coram nobis being used. Due to the nature of the writ, however, these cases may not be easily searchable online databases. ← Back to Browse
