DAVIS
v.
The STATE.
No. A98A1731.
Court of Appeals of Georgia.
January 14, 1999.
Head, Mullis, Thomas & Webb, Thomas J. Thomas, Atlanta, for appellant.
Carmen Smith, Solicitor, Cynthia G. Strong-McCarthy, Assistant Solicitor, for appellee.
BEASLEY, Presiding Judge.
John Davis appeals his convictions for having an alcohol concentration of .10 grams or more within three hours of driving (OCGA § 40-6-391(a)(5)), for driving under the influence of alcohol to the extent it was less safe (OCGA § 40-6-391(a)(1)), and for improper lane change (OCGA § 40-6-123). He enumerates five errors by the court: (i) denial of his motion to exclude evidence arising from the police stop; (ii) admission of the certifications that the breath-analyzing machine was in good working order; (iii) giving OCGA § 40-6-123 as a jury instruction; (iv) giving a mandatory inference instruction from OCGA § 40-6-392(b); and (v) refusing to strike an active duty police officer for cause.
1. Davis moved to exclude the evidence arising out of the stop, contending that it was *890 based on pretext. The officer testified that at 3:30 a.m., while following Davis' vehicle on a road with three westbound lanes, she witnessed him weave from the center lane toward the left lane and straddle the dividing stripes for twenty feet, return to the center lane, weave toward the right lane and straddle those dividing stripes for ten feet, and return to the center lane. She stopped him and, upon smelling alcohol on his breath, conducted four field sobriety tests that he performed poorly. After he tested positive for alcohol, she placed him under arrest for DUI. He consented to a chemical analysis of his breath, which showed his alcohol concentration to be .110.
The court denied the motion to exclude, finding the evidence showed the officer had an articulable suspicion to stop Davis for DUI and improper lane change. The court appeared to reject Davis' arguments that the weaving was minimal and was a mere pretext for the stop. On appeal Davis urges that the weaving was at most only a technical violation of OCGA § 40-6-48(1) and, similar to the defendant in Brantley v. State,[1] that we should construe the search and seizure clause of the Georgia Constitution to prohibit pretextual stops even though they are not prohibited by the Fourth Amendment.[2] "This is a question of constitutional construction which will have to be decided by the Supreme Court of Georgia."[3] Because the court did not err in finding no pretext, this issue is not reached for review and no transfer to the Supreme Court is required.[4] Moreover, the state constitutional question, although raised in the written motion, was not explicitly ruled on below, which also precludes review.[5]
OCGA § 40-6-48(1) provides that "[a] vehicle shall be driven as nearly as practicable entirely within a single lane and shall not be moved from such lane until the driver has first ascertained that such movement can be made with safety." Weaving without reason into nearby lanes violates this statute.
"Numerous cases have held that weaving out of one's lane justifies a stop.... Most of these cases focus on the weaving not as a traffic offense but as an indication that the driver was possibly intoxicated, which in this context authorized police to stop the driver to determine if the suspicion, a reasonable one, was accurate. This Court has specifically determined that an officer's observation of a motorist's `weaving' may serve as sufficient reason to warrant an investigative stop for a possible DUI violation. Thus the behavior giving rise to the reasonable suspicion need not be a violation of the law.... [T]he police can stop drivers who engage in erratic driving behavior, even if it is simply weaving within a lane."[6]
Davis' behavior (lack of adequate control of car) justified the stop.[7] Evidence supported the court's inferred finding that the stop was not pretextual, particularly in light of Davis' failure to identify an alleged pretext for the stop.[8]
2. Pursuant to OCGA § 40-6-392(f), the court admitted sworn documents certifying that the breath-testing device used to determine Davis' alcohol concentration had been thoroughly tested and was in good *891 working order and that all of its electronic and operating components prescribed by the manufacturer were properly attached. Davis challenges the establishment of the certificates as business records under OCGA § 24-3-14.
Brown v. State[9] held such certificates are admissible "upon a proper foundation being established" and specifically approved the foundation for business records in OCGA § 24-3-14. "The foundational requirements of OCGA § 24-3-14(b) are that a witness who is familiar with the method of keeping records testifies to facts which show that the record sought to be admitted was made in the regular course of business at the time of the event or within a reasonable time thereafter."[10]
It is not disputed that the State presented a witness, familiar with the certificates and the method of creating and keeping them, who testified they were created and maintained in the regular course of police business. Davis claims the witness did not testify the certificates were made within a reasonable time of the testing. This witness not only so testified, but so did a second witness. Additionally, the notary jurat for each certificate confirmed it was filled out on the day of inspection.[11] Unlike the cases cited by Davis,[12] the State laid the proper foundation.[13]
3. Claiming he was tried for an offense under OCGA § 40-6-48, Davis contends the court erred in reading OCGA § 40-6-123 as part of its jury charge. Davis is confused; he was tried for and convicted of improper lane change, an offense under OCGA § 40-6-123. The State dropped the "failure to maintain lane" charge, an offense under OCGA § 40-6-48, at the beginning of trial. The court did not err.
4. But the court did commit reversible error in two respects. First, the judge instructed the jury that "if there was at that time an alcohol concentration of 0.08 grams or more, it shall be inferred that the person was under the influence of alcohol as prohibited by Code Section 40-6-391." This mandatory inference, even though paraphrased in the language of OCGA § 40-6-392(b)(3), impermissibly shifted the burden to Davis to prove his innocence of the DUI charge under OCGA § 40-6-391(a)(1) (less safe to drive).[14] The DUI conviction under OCGA § 40-6-391(a)(5), which defines DUI as the act of having an alcohol concentration of .10 or more within three hours of driving, is not affected by reading to the jury the language of OCGA § 40-6-392(b).[15]
5. Reversal of all convictions is required by the second error. Despite Davis' request, the court refused to strike for cause a juror on the panel who was an active duty police officer. Davis was forced to use a peremptory strike to remove the officer and exhausted his peremptory strikes during jury selection.
Hutcheson v. State[16] held that if full-time officers are challenged for cause in a criminal case, they must be removed, and that failure to do so is reversible error. Although reversal was at one time contingent on the defendant using a peremptory strike to remove the juror and on the defendant exhausting his peremptory strikes during the selection *892 process,[17] circumstances which Davis happens to meet, such is no longer required.[18] The statement by the officer that he could decide the matter impartially is immaterial.[19] Accordingly, all convictions are reversed, and Davis is entitled to a new trial.
Judgments reversed on all counts.
