OHIO FIRST DISTRICT COURT OF APPEALS
F ISCHER , Judge.
{¶1} Following a bench trial, defendant-appellant Mama Diallo was
convicted of possessing more than 200 grams but less than 1000 grams of marijuana
in violation of R.C. 2925.11(A), a fifth-degree felony. R.C. 2925.11(C)(3)(c). In his
single assignment of error, Diallo argues that his conviction was contrary to the
manifest weight of the evidence. See State v. Thompkins, 78 Ohio St.3d 380, 387,
1997-Ohio-52,
678 N.E.2d 541.
{¶2} While reviewing the entire record to assess the merits of his appeal,
we found no written jury waiver signed by Diallo. This omission is plain error that
we may address sua sponte. State v. Pflanz (1999), 135 Ohio App.3d 338, 339,
733
N.E.2d 1212, citing Civ.R. 52(B).
{¶3} Section 5, Article I, of the Ohio Constitution guarantees that the “right
of trial by jury shall be inviolate … .” Likewise, the Sixth Amendment to the
United States Constitution, made applicable to the states through the Fourteenth
Amendment, provides that “[i]n all criminal prosecutions, the accused shall enjoy the
right to a speedy and public trial, by an impartial jury of the State and district
wherein the crime shall have been committed … .” State v. Lomax, 114 Ohio St.3d
350,
2007-Ohio-4277,
872 N.E.2d 279, ¶6, citing Duncan v. Louisiana (1968),
391
U.S. 145,
88 S.Ct. 1444.
{¶4} In a serious offense case, the defendant may knowingly, intelligently,
and voluntarily waive in writing his or her right to a jury trial. Crim.R. 23(A). Under
R.C. 2945.05, this waiver must be “(1) in writing, (2) signed by the defendant, (3)
filed, (4) made part of the record, and (5) made in open court.” Lomax at ¶9. Absent
strict compliance with these statutory requirements, “a trial court lacks jurisdiction

to try the defendant without a jury.” State v. Pless, 74 Ohio St.3d 333, 1996-Ohio-
102,
658 N.E.2d 766, paragraph one of the syllabus. See, also, Pratts v. Hurley,
102
Ohio St.3d 81,
2004-Ohio-1980,
806 N.E.2d 992, ¶26 (explaining that the failure to
comply with R.C. 2945.05 does not affect a trial court’s subject-matter jurisdiction,
but rather involves “error in the court’s exercise of its jurisdiction.”).
{¶5} Because Diallo was tried for a serious offense, he had to waive his
right to a jury trial pursuant to R.C. 2945.05 for the trial court to conduct a bench
trial. State v. Taylor, 1st Dist. No C-110062, 2011-Ohio-4648, ¶5. See also Crim.R.
2(C) (defining “serious offense” as including “any felony”). There is, however, no
written jury waiver signed by Diallo in the record. Thus, the trial court erred in the
exercise of its jurisdiction by trying Diallo without a jury. See
id.
{¶6} Faced with this plain error, we must reverse the judgment of the trial
court and remand the cause for further proceedings consistent with this opinion and
the law. Because this disposition renders Diallo’s single assignment of error moot,
we decline to address it. See App.R. 12(A)(1)(c); Taylor at ¶6.
Judgment reversed and cause remanded.
S UNDERMANN , P.J., and C UNNINGHAM , J., concur.
