OPINION
T1 Defendant Ronnie M. Curry appeals his conviction for possession of a controlled substance, see Utah Code Ann. § 58-37-8(2) (Supp.2008), and possession of drug paraphernalia, see id. § 58-87a-5(1) (2002). We reverse and remand.
BACKGROUND
2 On the evening of February 18, 2004, a Roosevelt City Police officer and an Adult Probation and Parole agent entered Defendant's home in search of Defendant's brother, a probationer. While in the home, the officer and the agent obtained information sufficient to cause them to believe that Defendant and others had used marijuana on the premises. After Defendant refused to consent to a search of his home, the police officer obtained a search warrant. After finding marijuana and drug paraphernalia, the police officer arrested Defendant. Defendant was charged with possession of a controlled substance, see id. § 58-37-8(2), and possession of drug paraphernalia, see id. § 58-87a-5(1).
13 Defendant moved to suppress the evidence, statements, and admissions obtained by the officer on the evening of his arrest, and requested an evidentiary hearing on the motion. On the date of the suppression hearing, Defendant's counsel failed to appear as a result of illness, which was later clarified as a serious heart attack. Despite being informed that defense counsel would not appear due to illness, the trial judge proceeded with the hearing, stating that he was prepared to rule on the motion based on the pleadings alone. The trial judge then allowed Roosevelt City (the City) to proffer evidence and present testimony from the Adult Probation and Parole agent and the *485 Roosevelt City Police officer who arrested Defendant. The trial judge did not provide Defendant with an opportunity to present his version of the facts or to cross-examine the City's witnesses. At the completion of the hearing, the trial judge denied Defendant's motion to suppress.
4 Defendant entered a conditional guilty plea pursuant to State v. Sery,
ISSUES AND STANDARDS OF REVIEW
T5 Defendant urges this court to reverse the trial court's denial of his motion to suppress, arguing that the trial court violated his Sixth Amendment right to counsel by conducting a suppression hearing in the absence of his attornet.
1
Ordinarily, we review the "factual findings underlying a trial court's decision to grant or deny a motion to suppress evidence" under a "clearly-erroneous standard," and we review the trial court's legal conclusions for correctness." State v. Peterson,
ANALYSIS
T6 We have held that "the Sixth Amendment, the Utah Constitution, and state statutory law ... guarantee an accused the right to be represented by counsel." State v. McDonald,
T7 The City contends that Defendant's claim fails because, under a harmless error analysis, he cannot show prejudice caused by the absence of counsel since the trial court was prepared to deny the motion to suppress based on the pleadings alone.
2
In essence, the City argues that the absence of defense counsel at the suppression hearing below did not so "affect[ contaminate[ entire criminal proceeding" that reversal is warranted. Satterwhite v. Texas,
18 "In most cases, if the reviewing court [holds] that a constitutional error was harmless beyond a reasonable doubt, it need not reverse." State v. Kell,
19 We conclude that, under the facts and circumstances of this case, Defendant was denied his right to counsel at a critical stage of the proceeding. 3 The sup *486 pression hearing constituted a critical stage of the proceeding because it was Defendant's opportunity to contest the admissibility of the evidence upon which the City's entire case against him was based. The record indicates that Defendant's attorney did not appear at the suppression hearing due to a serious illness. As a result, Defendant was effectively denied an opportunity at the hearing to cross-examine the City's witnesses and to put on evidence of his own version of the facts leading up to the search of his home, which ultimately resulted in his arrest. Defendant's motion to suppress set out a version of the facts patently different than that proffered by the prosecution, and Defendant's counsel specifically requested an evi-dentiary hearing. These facts indicate that Defendant and his attorney viewed the hearing as a valuable opportunity to present Defendant's case, which deserved full consideration by the trial court, aided by the skill and experience of Defendant's attorney.
{10 Taken together, these facts persuade us that the trial court denied Defendant his right to counsel at a critical stage of his criminal proceeding. See Wagstaff,
CONCLUSION
111 We reverse and remand the trial court's order denying Defendant's motion to suppress evidence. On remand, Defendant shall have the option to withdraw his conditional guilty plea pursuant to rule 11(i) of the Utah Rules of Criminal Procedure. See Utah R.Crim. P. 11).
T 12 WE CONCUR: JUDITH M. BILLINGS and WILLIAM A. THORNE JR., Judges.
Notes
. Because of our holding on Defendant's right to counsel claim and the absence of a fully developed record, we do not address Defendant's claims that his motion to suppress should have been granted on the merits.
. Defendant preemptively argues that we may reach his right to counsel claim based on plain error or exceptional circumstances. See State v. Nelson-Waggoner,
. Critical stages of a criminal proceeding include arraignment, preliminary hearing, and trial. See Hamilton v. Alabama,
