Ex post facto laws forbid retroactive application of statutes increasing the severity of criminal penalties.[278]  The central question for ex post facto purposes is whether the law changed the legal consequences of acts completed before its effective date.[279]  If so, and if that law increased the punishment authorized for the offense, the new law may not be applied retroactively to the defendant’s detriment.[280]

 


[278] Collins v. Youngblood, 497 U.S. 37, 42 (1990).

[279] See Weaver v. Graham, 450 U.S. 24, 31 (1981).

[280] In re Dewing, 19 Cal.3d 54 (1977) (among ex post facto laws are those that retroactively modify the time of discharge from custody to the substantial detriment of the defendant, thereby in effect increasing the punishment previously imposed for his crime).
