In People v. Flowers, 138 Ill. 2d 218, 237, 561 N.E.2d 674, 149 Ill. Dec. 304 (1990), the Illinois Supreme Court explicitly adopted the standard of Teague when deciding if a new constitutional rule of criminal procedure can function retroactively as a basis for a collateral attack. While the Illinois Supreme Court noted that the rule adopted in Teague was applied to bar application of a new constitutional rule in habeas corpus actions pending in the Federal courts, the court found that the collateral review involving an action in state court brought pursuant to the Post-Conviction Hearing Act was sufficiently similar to that involved in Teague. Flowers, 138 Ill. 2d at 237-38.
