        Argued January 7—officially released May 26, 2016*

 Mark Rademacher, assistant public defender, with
whom was Lisa J. Steele, for the appellant (defendant).
   Harry Weller, senior assistant state’s attorney, with
whom, on the brief, were Kevin T. Kane, chief state’s
attorney, John C. Smriga, state’s attorney, Jonathan

                                  Opinion

   PER CURIAM. A jury found the defendant, Russell
Peeler, guilty of, among other things, one count of capi-
tal felony in violation of General Statutes (Rev. to 1999)
§ 53a-54b (8) and one count of capital felony in violation
of General Statutes (Rev. to 1999) § 53a-54b (9) in con-
nection with the 1999 shooting deaths of a woman and
her young son, and, following a capital sentencing hear-
ing, the trial court, Devlin, J., rendered judgment impos-
ing two death sentences.1 This appeal of the defendant’s
death sentences is controlled by State v. Santiago, 318
Conn. 1, 122 A.3d 1 (2015), in which a majority of this
court concluded that, following the enactment of No.
12-5 of the 2012 Public Acts (P.A. 12-5), executing
offenders who committed capital crimes prior to the
enactment of P.A. 12-5 would offend article first, §§ 8
and 9, of the Connecticut constitution. See, e.g., Con-
way v. Wilton, 238 Conn. 653, 658–62, 680 A.2d 242
(1996) (explaining scope of and rationale for rule of
stare decisis). Our conclusion that the defendant’s
death sentences must be vacated as unconstitutional
in light of Santiago renders moot the defendant’s other
appellate claims.
   The judgment is reversed with respect to the imposi-
tion of two sentences of death and the case is remanded
with direction to impose a sentence of life imprison-
ment without the possibility of release on each capital
felony count; the judgment is affirmed in all other
respects.
  In this opinion ROGERS, C. J., and PALMER, EVE-
LEIGH, McDONALD and ROBINSON, Js., concurred.
   * May 26, 2016, the date that this decision was released as a slip opinion,
is the operative date for all substantive and procedural purposes.
   This case originally was argued before the same panel of justices on July
10, 2014. This court granted the state’s request for supplemental argument
on November 30, 2015, which was heard on January 7, 2016.
