In this prosecution for multiple alternative counts of driving under the influence of alcohol or drugs, plus possession of less than one ounce of marijuana, the State Court of DeKalb County granted John H. Coe's motion to suppress the results of a chemical test of Coe's urine. Pursuant to OCGA 5-7-1
(a) (4), the State brings this direct appeal. Viewed in the light most favorable to the trial court's determination, the evidence adduced at the suppression hearing authorized the following facts:
On February 10, 1998, police were conducting a driver's license and insurance roadblock, and Coe was stopped at approximately 2:00 a.m. While Coe was searching for his documents, the officer "was able to detect a slight odor of an alcoholic beverage coming from Mr. Coe's person." Coe, whose eyes were bloodshot and watery, stated he had consumed two beers. After the officer administered the horizontal gaze nystagmus, the walk and turn, and the one-leg stand field sobriety tests, he felt Coe was impaired and formally placed him under arrest for driving under the influence. Once Coe was placed in the rear of the patrol car, he was read the implied consent notice for suspects age 21 and over and was requested to submit to a chemical test of only his breath. A subsequent search of Coe's vehicle incident to that arrest revealed suspected marijuana in clear plastic bags plus some suspected marijuana cigarettes. The results of a breath test administered at the jail registered a blood alcohol concentration of 0.045 grams percent. At that point, the arresting officer read Coe his implied consent notice again and asked him to submit to a urine test. Coe agreed and submitted to the urine test.
The trial court denied the motion to suppress the marijuana found in the vehicle but granted the motion to suppress the results of the test of defendant's urine because Coe was never cautioned of his rights under Miranda v. Arizona, 1
despite his formal arrest. In three enumerations of error, the State contends this ruling is erroneous because state law, either as amended or as in effect at the time, specifically allowed the investigating officer to request a urine test after a breath test. We agree the statute in effect at the time authorized the State to request a urine test after a breath test and reverse.
1. In the version of OCGA 40-5-67.1
(a) in effect on February 10, 1998, the General Assembly provided that, "[s]ubject to Code Section 40-6-392
, the requesting law enforcement officer shall designate which test shall be administered, provided that the officer shall require a breath test or a blood test and may require a urine test." And in State v. Warmack, 2
this Court held that this plain statutory language authorized the requesting officer to select a breath test and a urine test or a blood test and a urine test. But Warmack went on to hold 3
that, because state law affords greater protection against self-incrimination than the federal constitution, "where the driver is already in State custody, as here, the request to undergo further State testing must be preceded by Miranda warnings." 4
Complying with this ruling, the trial court suppressed the results of Coe's urine test, since it was undisputed Coe was not given Miranda warnings before choosing to submit to the second State-administered test.
2. Under the law in place at the time in question, as well as now, routine roadside questioning does not constitute custodial interrogation triggering the protections of Miranda, 5
because the detainee is generally not in custody or under arrest. 6
If roadside questioning develops into an arrest, the protection of Miranda arises, 7
and the arrestee is entitled to suppress certain evidence obtained without proper Miranda warnings, such as the results of field sobriety tests. 8
But neither due process nor the Georgia privilege against self-incrimination codified at OCGA 24-9-20
(a) is implicated by the choice granted by the Georgia Implied Consent Statute whether to submit to a chemical test of bodily substances such as blood, breath, or urine. 9
The distinction lies between performing incriminating acts, such as field sobriety tests, and submitting to breath, blood, or urine tests. 10
The State "cannot force a defendant to act, but [nevertheless] can, under proper circumstances, produce evidence from his [body]." 11
Thus, an arrestee is not, under Georgia constitutional or statutory law, entitled to Miranda warnings before deciding whether to submit to the State's request for an additional test of breath, blood, or urine. 12
The Warmack decision is contrary to the earlier rulings of our Supreme Court that the Georgia protections against self-incrimination are not implicated by chemical testing of bodily substances. Since the Court of Appeals has no authority to overrule or modify a decision of the Supreme Court, 13
Warmack itself is hereby overruled. The trial court's suppression of the urine test results can-
not be sustained on the ground that Miranda warnings were not given to a DUI arrestee before he decided to submit to a urine test after taking a breath or blood test. 14
3. As noted above, the then-applicable version of OCGA 40-5-67.1
(a) plainly required either a breath test or a blood test of the suspect driver and equally plainly authorized a discretionary urine test. There was certainly no statutory requirement that the requesting officer designate all tests to be requested before the initial test is taken, and any contrary language in Warmack is hereby disapproved. In our view, former OCGA 40-5-67.1
(a) clearly authorized a subsequent urine test if the requesting officer deemed it necessary or useful after seeing the results of the required breath or blood test. Since the requesting officer here was authorized by statute to request the urine test after seeing the equivocal results of Coe's breath test (0.045 grams percent) and because the Georgia law on self-incrimination does not bar the results of chemical tests on bodily substances despite the absence of post-arrest Miranda warnings, the trial court erred in suppressing the urine test results in this case.
