Gillett v. State, 148 So. 3d 260

Gillett was convicted of two counts of capital murder and sentenced to death; conviction affirmed on direct appeal in Gillett v. State, 56 So.3d 469 (Miss.2010) and later challenged by post-conviction relief petition.
The post-conviction petition raised six issues, organized around aggravating factors, notice, ineffective assistance, due process, and cumulative error.
Issues included expansion of the underlying robbery aggravator, notice/fairness of a “continuous-action” theory, ineffective assistance for mitigation investigation, ineffective assistance for sentencing-phase prosecutorial misconduct, due-process challenges to reweighing aggravators, and cumulative error.
The majority ultimately held issues (1) and (2) meritless, but found a due-process violation regarding sentencing (issue 5), vacated the death sentences, and remanded for a new sentencing hearing.
Because issue 5 was dispositive, the Court did not address issues 3, 4, and 6 further in the decision.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Expansion of underlying robbery aggravator	Gillett argued S-5/S-6 expanded the aggravator and violated notice	Gillett contends misdefinition/incomplete notice allowed continuous-chain theory	Merits rejected; instructions proper and not violative of due process
Continuous-action doctrine and notice	Gillett lacked fair notice for continuous-chain theory	Mississippi follows one-continuous-transaction rationale	Merits rejected; doctrine properly applied on direct appeal
Ineffective assistance—mitigation investigation	Counsel failed to investigate background to present mitigating evidence	No reversible prejudice shown; claims moot after remand on issue 5	Moot/denied due to dispositive issue 5 (sentencing)
Ineffective assistance—sentencing phase misconduct	Counsel failed to object to prosecutorial misconduct during sentencing	No reversible error established without considering issue 5	Moot/denied due to dispositive issue 5 (sentencing)
Due-process in sentencing (reweighing of aggravators)	Brown v. Sanders requires reversal when invalid aggravator was considered	Clemons allows reweighing or harmless-error analysis; statute authorizes reweighing	Due-process violated; death sentences vacated and remanded for new sentencing
