State v. Cretella, 2018 Ohio 3245

Christopher M. Cretella pleaded guilty in Nov. 2015 to robbery and assault on an officer and was sentenced to a total of four years.
He filed a motion for jail-time credit on July 1, 2016; the trial court denied it on Aug. 18, 2016, and this court affirmed on appeal in May 2017.
Cretella subsequently filed two additional, identical motions for jail-time credit (July 13, 2017 and Sept. 22, 2017).
The trial court denied the successive motions, concluding it had already ruled on the issue in Aug. 2016.
Cretella appealed, arguing due-process and equal-protection violations based on alleged statutory entitlement to additional jail-time credit.
The state urged the successive motions were barred by res judicata; the appellate court agreed and affirmed.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the trial court erred in denying successive motions for jail-time credit	State: successive post-sentence motions are barred by res judicata	Cretella: trial court violated due process and equal protection by failing to reduce each sentence by credited jail time	Res judicata bars successive post-sentence jail-time-credit motions; court affirmed denial
