State v. Davis, 958 N.E.2d 1260

This case is on remand from the Ohio Supreme Court to readdress plain-error in admitting spousal testimony without a competency election finding.
The defendant was charged in 2007 with 31 counts of rape and gross sexual-imposition involving his two nieces, D.T.1 and D.T.2.
A 2008 jury convicted him on multiple counts; the trial court sentenced him to life in prison.
The prior panel held that failure to inform the wife of spousal testimony rights was not reversible plain error given the strong victim testimony.
On review, the Ohio Supreme Court clarified that plain-error review requires a but-for analysis showing prejudice and miscarriages of justice, not automatic reversal.
This opinion analyzes whether the admission of spousal testimony, and related evidentiary rulings, affected the trial’s outcome.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Spousal testimony and plain error	Davis argues admission of wife’s testimony without a competency finding was reversible plain error.	Davis argues error prejudiced the defense and warrants reversal.	No reversible plain error; outcome would be the same.
Evid.R. 404(B) other-acts evidence	Proffered mother’s history evidence should be admissible to show motive/identity.	Evidence of old misconduct was prejudicial and improper under 404(B).	Not plain error; evidence falls under 404(A)(1) or was opened by defense; admissible.
Ineffective assistance of counsel	Counsel failed to object to inadmissible evidence and to the wife’s testimony.	Strategy and opened-door doctrine justify previously failing to object; prejudice not shown.	No reversible ineffective-assistance prejudice; convictions affirmed.
