OPINION
In this case, we decide whether the state must provide a breath sample to a defendant charged with driving under the influence of alcohol when the defendant has given a deficient sample in the breath test, but the state still uses the test results at trial. Defendant David Allen Yannoy was convicted following a jury trial of one count of aggravated driving under the influence of alcohol, a class 5 felony. He appeals from his conviction and from the trial court’s order suspending imposition of sentence and placing him on probation for three years. He raises the following issues on appeal:
1. whether the state’s interference with his right to counsel required that the charge against him be dismissed;
2. whether the state’s failure to inform him of his right to an independent blood alcohol test required that the charge against him be dismissed;
3. whether the state’s failure to provide him with a breath sample for independent testing required the suppression of the breath test results that the state introduced at trial; and
4. whether the trial court abused its discretion in denying his motion to allow a previously undisclosed witness to testify-
We reverse and remand for a new trial because we conclude that the trial court erred in denying defendant’s motion to suppress the breath test results.
FACTUAL AND PROCEDURAL HISTORY
On the evening of August 31, 1990, Scottsdale police officers observed defendant’s automobile going forty miles per hour in a twenty-five mile per hour zone. When the officers stopped defendant, they found that he was driving on a revoked license and that he had alcohol on his breath. They arrested him for aggravated driving under the influence of alcohol. 1 The officers informed defendant of his Miranda rights 2 and of the provisions of Arizona’s implied consent law, 3 and transported him to the police station for a breath test.
Defendant was tested twice on an intoxilyzer. The results indicated that the machine had received a deficient breath sample on both tests. Defendant was not advised of his right to have an independent test done, and no breath samples were preserved for him for this purpose.
At trial, the state’s intoxilyzer expert, Lu-den Haag, testified that a deficient sample can occur when the person being tested fails to blow all of the breath that is in his lungs into the machine. Haag explained that the reading obtained from a deficient sample will be lower than a person’s actual BAC. Officers David Bickel and Philip Hazlett testified that defendant’s breath samples were deficient because each time defendant took the test, he blew some of his breath out of the side of his mouth instead of into the machine.
*209 Prior to trial, defendant filed a motion to suppress the test results. He also filed a motion to dismiss the charge against him on the ground that the officers had refused to allow him to call an attorney after he was arrested. The trial court denied both motions. Although defendant’s breath samples were deficient, the state introduced the intoxilyzer results into evidence at trial. The first test registered a BAC of .194, and the second test registered a BAC of .161. On the basis of these results, Haag testified that defendant’s actual BAC exceeded .10 when he took the tests and that it exceeded .21 when he was stopped by the police. Defendant filed a timely notice of appeal from his conviction and from the order suspending imposition of sentence and placing him on probation for three years.
DISCUSSION
I. Alleged Interference with Bight to Counsel
Defendant initially argues that the trial court should have dismissed the charge against him because his right to counsel was violated. At the hearing on the motion to dismiss, defendant testified that he asked to speak with his attorney prior to taking the breath test. He maintained that the police told him just to take the test. Two police officers testified that defendant did not ask to call an attorney.
If defendant asked to speak with an attorney, he had a right to do so before taking the test. Ariz.R.Crim.P. 6.1(a);
State v. Juarez,
II. Failure to Advise of Bight to Independent Test
Defendant also argues that the trial court should have dismissed the charge against him because the officers did not advise him of his right to an independent blood alcohol test. We conclude that the officers were not required to inform defendant of his right to an independent test under the circumstances of this case.
Defendant cites
Montano v. Superior Court,
III. Failure to Preserve Breath Samples
Defendant next asserts that the trial court should have suppressed the breath test results because the state did not provide him with a breath sample for an independent test. The state responds that defendant waived *210 this issue by raising it for the first time in his reply in support of the motion to suppress. Although the state made the same argument in the trial court, the trial court decided the issue on the merits and ruled that defendant had waived the right to his own sample by giving deficient samples both times that he was tested.
The fact that an issue may have been raised in an untimely fashion does not preclude this court from reviewing the trial court’s ruling on the merits of the issue.
See United States v. Ramos-Zaragosa,
The state next argues that defendant waived his right to have a breath sample preserved by failing to give an adequate sample. Beginning with
Baca v. Smith,
The state notes that AR.S. section 28-691(B) provides that a DUI defendant’s failure to “successfully complete” the blood alcohol test will be deemed a refusal to take the test. It argues that by failing to give a sufficient sample in the present case, defendant in effect refused to take the test and waived his right to a sample. It cites Miller and Ramos in support of this contention. We disagree.
Section 28-691(B) only addresses the civil suspension penalty for refusing to take the test.

It does not govern the state’s duty to preserve for independent testing breath samples obtained pursuant to the implied consent law.
See Sherrill v. DOT,
In
State v. Velasco,
The state’s concern that this decision will cause DUI defendants to intentionally give deficient samples is unfounded. First, a defendant will not be able to offer the results that he has obtained from independent testing of a deficient sample in evidence to prove his actual BAC. A deficient sample lacks sufficient foundation to be admitted for this purpose because it only measures a portion of a person’s BAC. Thus, a defendant who has given a deficient sample will only be able to use the sample to show that the state’s results are inaccurate. This is precisely the use that Baca contemplates.
Second, a DUI defendant who gives a deficient sample remains subject to the civil suspension penalty that section 28-691(B) imposes for failing to successfully complete the test. See
Kuznicki v. Arizona Dep’t of Transp.,
The state contends, however, that in
California v. Trombetta, 467
U.S. 479,
In
Velasco,
the court found that it was unnecessary to decide whether
Trombetta
overruled
Baca
and its progeny.
The court also distinguished
Trombetta
in
Oshrin v. Coulter,
While the state normally has no obligation to aid a suspect in gathering potentially exculpatory evidence, the umque evidentiary circumstances attendant to DWI arrests justify a narrow exception. The Due Process Clause of the Arizona Constitution guarantees to [a] DWI suspect[] a “fair chance to obtain independent evidence of sobriety essential to Ms defense at the only time it [is] available.”

In
State v. Youngblood,
Driving under the influence cases are arguably umque for a variety of reasons. The evidence is in the defendant’s own body. Usually the defendant is in custody and the state has the right to take a breath or blood sample. Whatever our DUI jurisprudence means, the differences are too great to transpose its peculiar rules to any other setting. Efforts in the court of appeals to extend tMs “narrow exception” are expressly rejected.
Id.
The Arizona Supreme Court is the final arbiter of Arizona Constitutional issues.

CONCLUSION
Our disposition makes it unnecessary for us to address defendant’s argument that the trial court abused its discretion in denying Ms request to call a previously undisclosed witness. This issue will not reoccur if the witness is properly disclosed prior to the new trial.
As we have stated, the trial court should have suppressed the intoxilyzer results because the state failed to preserve a sample of defendant’s breath for independent testing. We therefore vacate defendant’s conviction and the order placing him on probation and remand tMs matter for a new trial at wMch the intoxilyzer results will be suppressed.
Notes
. Arizona Revised Statutes section 28-697(A)(l) (Supp.1992) (formerly section 28-692.02(A)(l)) provides that a person is guilty of aggravated driving under the influence of alcohol if he drives under the influence of alcohol while his driver's license is suspended, canceled, revoked, or refused.
.
See Miranda v. Arizona,
. Arizona's implied consent law, A.R.S. section 28-691(A) (Supp.1992), provides in pertinent part as follows:
Any person who operates a motor vehicle within this state gives consent ... to a test or tests of his blood, breath, urine or other bodily substance for the purpose of determining alcohol concentration ... if arrested for any offense arising out of acts alleged to have been committed ... while the person was driving or in actual physical control of a motor vehicle while under the influence of intoxicating liquor.
. Section 28-691(B) provides in pertinent part that any person who fails to take and successfully complete a blood alcohol test will have his license or driving permit suspended or denied for one year.
