******************************************************STATE OF CONNECTICUT v. MARK A. TENAY (AC 35045)
Gruendel, Robinson and Alvord, Js.* Argued November 18, 2013—officially released May 13, 2014 (Appeal from Superior Court, judicial district of Ansonia-Milford, geographical area number twentytwo, Keegan, J.)
Jeremiah Donovan, for the appellant (defendant). Harry Weller, senior assistant state’s attorney, with whom were Kevin D. Lawlor, state’s attorney, and Kevin S. Russo, supervisory assistant state’s attorney, for the appellee (state).Opinion ROBINSON,J. Thedefendant, MarkA. Tenay, appeals from the judgment of conviction, rendered after ajury trial on the first part of an information, of operating a motor vehicle while under the influence of alcohol in violation of General Statutes § 14-227a (a) (1),1 and following a trial to the court on a part B information,2 of beingathreetimeoffenderpursuantto GeneralStatutes § 14-227a (g) (3). The defendant claims on appeal that the trial court improperly (1) excluded from evidence duringthejurytrialportions ofcertain hospital records that pertained to medical treatment that he received following his arrest; (2) admitted into evidence during the jury trial the results of a finger dexterity roadside sobriety test without first determining the scientific validity ofthat particular test in accordance with State

v. Porter, 241 Conn. 57, 80–90, 698A.2d 739 (1997), cert. denied, 523 U.S. 1058, 118 S. Ct. 1384, 140 L. Ed. 2d 645 (1998); and (3) admitted into evidence during the trial to the court on the part B information a certified copy of a case abstract detailing a Florida criminal action attributed to the defendant and a related fingerprint card. We agree withthe defendantthatthe abstractwas improperly admitted into evidence and, thus, reverse that part of the judgment finding the defendant to be
athree time offenderunder § 14-227a (g); we otherwise affirm the judgment of the trial court.3
The jury reasonably could have found the following facts. Early in the morning of April 18, 2009, Officer Jeffrey Nelson of the Milford Police Department was dispatched to Naugatuck Avenue, where he observed
a brown Jeep Cherokee with Vermont license plates partially on the front lawn of 1028 Naugatuck Avenue. Additional police officers, Matthew Mello and Gillian Gallagher, later arrived at the scene. The vehicle had considerable damage. The rearbumperwas hanging off ofthe vehicle, the passenger side ofthe vehicle looked to have been sideswiped, the front passenger side window was broken, and the front passenger side fender and headlight were damaged. There was no tire on the front passenger side of the vehicle, and a gouge in the pavement, which extended back from the scene approximately one mile to the off ramp of Interstate 95, indicated that the vehicle had traveled for a considerable distance on its rim without the tire.
When Nelson arrived, the defendant was seated in the driver’s seat of the vehicle with the door open. He
was confused and disoriented. His eyes had a glassy appearance, and he smelled strongly of alcohol. When Nelson inquired about the condition ofthe vehicle, the defendant responded that he may have struck a curb
a couple of blocks away, although the damage to the vehicle did not support that scenario. The defendant later indicated that he may have struck a mailbox or something else. Nelsonhadto repeathis requestforthedefendant’s driver’s license, registration and insurance card a few times before the defendant complied.
On the basis of initial observations, the defendant
was asked to perform certain field sobriety tests: the alphabet test, the walk and turn test, the one leg stand test, the horizontal gaze nystagmus test, and the finger dexterity test. Nelson first asked the defendant to perform the alphabet test, which required him to recite the alphabetfromAto Z. The defendantrespondedthat he was ‘‘not good’’ at reciting the alphabet because his first grade teacher had passed away in the middle of the school year, and, thus, he never learned to recite the alphabet properly. He nevertheless agreed to try. He could only recite the letters A through K, the latter which he pronounced as ‘‘key,’’ following which he recited, in order, the letters E, M and F.
Nelson next indicated that he was going to have the defendantperform awalk and turntest.4 Before Nelson could explain to the defendant what the test entailed, the defendant indicated that he would be unable to perform the test because of existing knee problems. Nelson instructed the defendant that he did not have to place the toe ofone foot againstthe heel ofthe other
as is usually required, but could keep them somewhat apart. Even with that accommodation, however, the defendant failedthe test. He walked nine steps forward and nine steps back, but counted fourteen steps, failed to keep his balance and stepped off of the line. The defendant refused to take the one leg stand test when asked by Nelson.5
Mello then conducted the horizontal gaze nystagmus test.6 Although Mello instructed the defendant to keep his head straight and only move his eyes, the defendant
was not able to comply and moved his head. At the maximum deviation point, the defendant’s eyes were ‘‘bouncing,’’ which was a strong indicator that he
was intoxicated.
Mello also conducted the finger dexterity test. The finger dexterity test requires the subject to count the fingers ofonehandbyusingthethumbto moveforward and back, touching the tips ofthe fingers starting with the index finger, while counting out loud from one to fourandthenbackwardfromfourtoone. Thedefendant failed the test because he performed the required tasks very slowly, he had to concentrate on his hands and focus on counting, and he swayed and lost his balance while performing the test. Having failed to perform adequately any ofthe roadside sobriety tests administered to him, the defendant
was arrested for operating his motor vehicle while under the influence, and he was transported to the Milford Police Department. While at the police department, the defendant refused to take a breathalyzer or
aurine testto determine his blood alcohol content. Thedefendantwas given asummons andreleased. The next day, he reported for medical treatment to the emergency room at Yale-New Haven Hospital. Additional facts and procedural history will be set forth as necessary. I
The defendant first claims that the court erred in redacting portions of medical records that he sought to introduce as full exhibits during the jury trial. The medical records atissue pertainto treatmentthe defendant received after his arrest. The defendant argues that the medical records in their unredacted form were necessary to his defense because they tended to show hisphysical andmental condition atthetime leadingup to his arrest, and, in so doing, supported an alternative explanation for his behavior and why he failed the field sobriety tests. The state argues that the defendant’s evidentiary claim fails because the court did notwholly exclude the profferedrecords, butmerelyredacted certain portions that either were irrelevant, constituted inadmissible hearsay, or would have confused thejury without some further explanation from a witness.7 The state also argues that the defendant has failed to prove that he was harmed bythe court’s redactions. We agree withthe state thatthe court did not abuse its discretion in redacting portions ofthe proffered medical records.
The following additionalfacts andproceduralhistory
are relevant to the present claim. Prior to the state resting its case, the defendant sought to make an offer ofproofregarding medical records that he had subpoenaedfromYale-NewHavenHospitalandthathewanted to introduce to the jury as full exhibits without a witness.8 The defendant wanted aruling from the court on the admissibility of the medical records prior to his deciding whether to testify on his own behalf.
The medical records at issue consist of four reports dated April 21, April 27, April 30 and May 11, 2009— each memorializing afollow-up visit that the defendant had after his initial treatment in the hospital’s emergency room on April 19, 2009—and an operative report detailing a knee surgery that the defendant underwent
on July 29, 2009. When the court inquired as to the relevancy ofthe records, the defendant argued that the records would show that he had visited the emergency
room the day after the incident and that he had complained ofproblems withhis left knee, whichultimately required surgery. According to the defendant, such evidence supported his defense theory that his knee impairment, and not his intoxication, had prevented him fromproperly executingthe walk andturntest and from taking the one leg stand test. The defendant also argued that the records indicated that he had suffered
acervicalstrainandwasprovidedwithacervicalcollar, which, the defendant argued, was relevantto showthat there had been ‘‘some collision that caused the defen-dant’s body to be thrown about.’’
The state objected to the proffered medical records being introduced as full exhibits. It argued that the medical records contained little relevant information. It also argued that they were replete with inadmissible hearsay in that they contained the authoring doctor’s recitation of statements the defendant had made with regard to the defendant’s medical history and to events that transpired prior to his arrest. Finally, the state argued that, without a witness, the records, which containedthe defendant’s self-reporting ofahistoryofconcussions and blackouts, could mislead the jury into believing that they were actual clinical diagnoses by the treating physician.
In response to the state’s relevancy argument, defense counsel stated that he was ‘‘not necessarily claimingthe entire document,’’ andindicatedsomewillingness to redact portions ofthe documents. As to the state’s hearsay arguments, defense counsel argued that he believedthatthe defendant’s statements could come inunderanexceptiontothehearsayruleforstatements made for the provision ofmedical services.9 The defendant did not directly respond to the state’s argument that the records contained information that could mislead the jury without an explanatory witness.
After taking a brief recess to review the documents further, the court, Keegan, J ., ruled on the record as follows: ‘‘[T]he majority ofthe documents are not relevant to the issues that the jury has to decide in this trial, namely, whether or not on the [day in] question [the defendant] was recklessly operating a motor vehicle, while under the influence of intoxicating liquors,
or any drugs, orboth.’’ The court also noted that ‘‘these records are confusing without a witness to explain the records.’’ The court concluded that it would ‘‘order a redaction of certain records to permit [the defendant] to introduce the records with respect to the fact that he had reported prior knee surgeries, and that he had
aknee surgeryinJulyof2009.’’ The courtalso indicated that it would do the redactions during the next break. The defendant stated for the record that he disagreed with the court’s decision to have the documents redacted. The courtlaterfurtherclarifiedits evidentiary ruling, stating that ‘‘[t]he court finds that only any complaint ofthe injury to the knee is relevant to the defendant’s claims about his ability to perform the roadside sobriety tests. So, that’s the part that the court would allowin, andwe do needto redactthe records forthat.’’ The court later provided the parties with copies of the redacted versions of the documents. Defense counsel offered the redacted versions for admission as full exhibits at the start of the defendant’s case, and they
were admitted without further objections.
We begin with the standard of review that governs
our consideration ofthe defendant’s evidentiary claim.‘‘It is axiomatic that [t]he trial court’s ruling on the admissibility of evidence is entitled to great deference.

. . . Accordingly, [t]he trial court’s ruling on evidentiary matters will be overturned only upon a showing of a clear abuse ofthe court’s discretion.

. . . Furthermore, [i]ndeterminingwhethertherehasbeenanabuse of discretion, every reasonable presumption should be made in favor of the correctness of the trial court’s ruling, and we will upset that ruling only for a manifest abuse of discretion.

. . . In a criminal case, an improper evidentiary ruling by the trial court is harmless ifthe reviewing court has a fair assurance that the
error did not substantially affect the jury’s verdict.’’ (Citation omitted; internal quotation marks omitted.) Statev. Williams, 146 Conn. App. 114, 124, 75 A.3d 668, cert. granted on other grounds, 310 Conn. 959, 82 A.3d 626 (2013). ‘‘[I]f an [evidentiary] impropriety is of constitutional proportions, the state bears the burden ofproving that the error was harmless beyond a reasonable doubt.

. . . When an improper evidentiary ruling is not constitutional in nature, the defendant bears the burden of demonstrating that the error was harmful.’’ (Internal quotation marks omitted.) State v. Longo, 106 Conn. App. 701, 708, 943 A.2d 488 (2008). ‘‘To the extent [that]
a trial court’s admission [or exclusion] of evidence is based on aninterpretation ofthe [Connecticut] Code of Evidence, our standard ofreview is plenary.’’ (Internal quotation marks omitted.) State v. Annulli, 130 Conn. App. 571, 579–80, 23 A.3d 808 (2011), aff’d, 309 Conn. 482, 71 A.3d 530 (2013). ‘‘Relevant evidence is evidence that has alogical tendency to aid the trier in the determination ofan issue.’’ (Internal quotation marks omitted.) State v. Thomas, 110 Conn. App. 708, 716, 955 A.2d 1222, cert. denied, 289 Conn. 952, 961 A.2d 418 (2008). ‘‘A clear statement of the defendant’s theory of relevance is all important in determining whether the evidence is offered for a permissible purpose.

. . . Ordinarily, we will not consider a theory of relevance that was not raised before the trial court.’’ (Internal quotation marks omitted.) State v. Crespo, 114 Conn. App. 346, 366, 969 A.2d 231 (2009), aff’d, 303 Conn. 589, 35 A.3d 243 (2012). ‘‘While relevantevidence isgenerallyadmissible, thetrialjudge has a certain amount of discretion in excluding such evidence; matters likely to mislead a jury, or to be misused by it, or to unnecessarily complicate a case,
or of slight, remote, or conjectural significance, ought nottobeadmitted.’’ (Internalquotationmarksomitted.) State v. Gooch, 186 Conn. 17, 23, 438 A.2d 867 (1982). Thus, even potentially relevant evidence properly may be excluded ifits probative value is outweighed by the danger of misleading the jury.
When asked at trial to explain the relevancy of the proffered medical records, the defendant argued thatthe records showed that he had reported to the emergency room shortly after the incident leading to his arrest complaining ofproblems with his left knee, and that he ultimately required surgery to correct the problems with the knee. According to the defendant, evidence of the knee injury was relevant because it supportedhistheoryofdefense ‘‘that [he] hadamedical condition that would, at least, with respect to the walk and turn and the one leg stand [tests], at least, impede his ability to perform those tests, as a result of that condition.’’ When the court asked ifthere was anything else the defendant wanted to argue with respect to relevancy, the defendant mentioned that the records also indicated that he had suffered a cervical strain and
was given a cervical collar, which he argued tended to support the notion that there had been some serious collision prior to his arrest. The defendant never explained to the court how evidence of a serious collision would aid thejury in its consideration ofwhether the defendant hadbeen intoxicatedwhile operatingthe vehicle or in resolving any other issue properly before the jury.10
The defendant also mentioned to the court that the records ‘‘containedadiscussionaboutpositive amnesia that the defendant suffered,’’ and also indicated selfreported, ‘‘subtle blackout type episodes.’’ The defendant did not explain the significance of that evidence, and, when the court indicated that it did not know what the term ‘‘positive amnesia’’ meant, the defendant immediatelyreturnedto adiscussion ofhis knee injury.
Onthe basis ofourreview ofthe record, we conclude that the only theory of relevancy offered by the defendant to the court at the time the court ruled on the admissibility of the medical records pertained to the knee injury evidence. The court ruled that it would allow the records in as a full exhibit with respect to evidence concerning the defendant’s knee injury. The rationale givenbythe courtforredacting otherportions of the records was that they contained material that
wasnotrelevantandthatmightmisleadthejurywithout further explanation. That rationale is fully supported bythe record. The defendanthas failedto establishthat the court abused its discretion in admitting only the redactedversionsoftheprofferedmedicalrecords, and, accordingly his claim to the contrary fails.
II
The defendant next claims that the court abused its discretion by admitting testimony regarding the defendant’s failure to pass the finger dexterity test without first determining whetherthattest is scientificallyvalid pursuant to Porter

. We disagree.
The following additional facts are relevant to our resolution ofthis claim. The state called Mello to testify about the two field sobriety tests that he administeredtothe defendant. Mellofirsttestified, withoutobjection, about administering the horizontal gaze nystagmus test to the defendant, and the results he observed. When the state asked Mello whether he had administered another test, defense counsel indicated that he had an objection that should be heard outside the presence of the jury. The jury was excused, after which defense counsel indicated that he objected to any testimony from Mello regarding the finger dexterity test without the state first making an offer of proof that the test satisfies the criteria for admissibility of scientific evidence as set forth in Porter

. Defense counsel argued that although he was aware of literature from the NationalHighwayTraffic SafetyAdministrationvalidating the use of the horizontal gaze nystagmus test, the walkandturntest, andtheonelegstandtestasstandard fieldsobrietytests, he knewofno suchscientificvalidation with regard to the finger dexterity test.
In response to questions from the court, Mello indicated that although the horizontal gaze nystagmus test, the walk and turn test, and the one leg stand test are the three standard field sobriety tests, the police also employ othertests capable ofgauging aperson’s motor skills and hand-eye coordination, such as the finger dexterity test. With respect to the finger dexterity test, Mello explained that if a person was under the influence, they might either miss touching a finger or count incorrectly. The state argued that it believed that the defense’s objectionpertained more to the weight ofthe evidence, not to its admissibility.
The court ruled as follows: ‘‘Well, as to whether or not a Porter hearing is necessary on finger dexterity, based on what the officer has said, it doesn’t sound scientific at all. It sounds no different to the walk and turn, which is to see whether or not the person can exhibit dexterity and count at the same time, as an indicator as to whether or not, you know, that could be used as a factor—to make a determination as to whether a person is intoxicated or not. So, because it sounds so similar to the walk and turn, using fingers instead of feet, the [c]ourt feels that it is admissible under the same standards that the walk and turn is admissible.’’ Defense counsel noted his objection for the record.11
The jury was brought back to the courtroom. In response to questions from the state, Mello explained tothejurywhatthefingerdexteritytestentailed, noting that the test allowed officers ‘‘to observe an individual at a normal task that they should be able to complete if they’re not under the influence of drugs or alcohol.’’ When he was asked to describe the defendant’s results, Mello testified: ‘‘He was very slow, concentrating on his hands, focusing on counting. Also, while doing that, he was swaying. That’s another indication. Someone who’s under the influence, when you ask them to donormal tasks, sometimes othernatural motor skills will start to fade away. At, which, at the time he was doing that, hestartedswaying, asifhewaslosinghisbalance.’’ On the basis ofhis observations and experience, Mello determined that the defendant had failed the test. ‘‘In Porter, this court followed the United States Supreme Court’s decision in Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 113 S. Ct. 2786, 125 L. Ed. 2d 469 (1993), and held that scientific evidence should be subjected to a flexible test, with differing factors that are applied on a case-by-case basis, to determine the reliability of the scientific evidence.

. . . Following [Porter], scientific evidence, and expert testimony based thereon, usually is to be evaluated under a threshold admissibility standard assessing the reliability of the methodology underlying the evidence and whether the evidence at issue is, in fact, derived from and based upon that methodology

. . . .’’ (Citations omitted; internal quotation marks omitted.) State

v. West, 274 Conn. 605, 630, 877 A.2d 787, cert. denied, 546 U.S. 1049, 126 S. Ct. 775, 163 L. Ed. 2d 601 (2005). Nevertheless, ‘‘certain types of evidence, although ostensibly rooted in scientific principles and presented by expert witnesses with scientific training, are not scientific for

. . . purposes of our admissibility standardforscientificevidence, eitherbeforeorafterPorter [was decided].

. . . Thus, even evidence with its roots in scientific principles, which is within the comprehension of the average juror and which allows the jury to make its own conclusions based on its independent powers of observation and physical comparison, and without heavyreliance uponthe testimony ofan expert witness, need not be considered scientific in nature for

. . . purposes of evidentiary admissibility.

. . . [E]vidence

. . . which merely places ajury

. . . in a position to weigh the probative value of the testimony without abandoning common sense and sacrificing independentjudgment to the expert’s assertions based
on his special skill or knowledge

. . . is not the type ofscientific evidence within the contemplation ofPorter, and similarly was not within the ambit of our standard for assessing scientific evidence prior to Porter.’’ (Citations omitted; internal quotation marks omitted.) Id., 631.
This court previously has concluded that, unlike the horizontal gaze nystagmus test, field sobriety tests like the walk and turn test and the one leg stand test, which ‘‘probe an individual’s sense of balance, his coordination and his abilities to comprehend and follow instructions,’’ are within the common knowledge oflayjurors, and, thus, do not constitute scientific evidence. State

v.Merritt, 36Conn.App. 76, 90–91, 647A.2d 1021 (1994), appeal dismissed, 233 Conn. 302, 659 A.2d 706 (1995). Such tests are not highly technical, nor do they require special skills or knowledge to be understood. See Statev. Gracia, 51 Conn. App. 4, 19, 719 A.2d 1196 (1998).
The courtinthe present case ruledthat, like the walk andturntest, the finger dexteritytestwas not scientific evidence. It based that decision on the testimony of Mello thatthe finger dexteritytestwas usedto evaluate
aperson’s motor skills and hand-eye coordination. The court correctly reasoned that the finger dexterity test, like the walk and turn test, required a test subject to demonstrate coordination while counting at the same time. The jury required no special skills or knowledge to evaluate the observational evidence provided by Mello of the defendant’s performance. The court did not err in determining that, like the walk and turn test andthe one leg standtest, the finger dexteritytest does not constitute scientific evidence as contemplated in Porter, and we reject the defendant’s claim that the court abused its discretion in admitting Mello’s testimony regarding the finger dexterity test without first conducting a Porter hearing.
III
The defendant next claims that the court improperly admitted into evidence during the part B trial a copy ofa criminal case abstract obtained from a court clerk in Santa Rosa County, Florida (abstract), and a related fingerprint card obtained from the Santa Rosa County sheriff. The defendant argues that information on the abstract and fingerprint card was inadmissible hearsay and that the state failed to lay a proper foundation for the documents’ admission under a hearsay exception for public records. We agree that the abstract was not properly admitted and that this constituted reversible
error.12
The following additionalfacts andproceduralhistory
are relevant to our review of the claim. The defendant
was charged in the part B information with being a repeat offendersubjectto an enhanced sentence pursuant to § 14-227a (g).13 According to the information, the defendant previously had been convicted of driving a motor vehicle while under the influence in Florida in 1996 and in Connecticut in 2002. The state, therefore, had the burden of proving those prior convictions beyond a reasonable doubt.14 To meet that burden, the statepresentedthetestimonyofIanShackleton, acriminal justice secretary II with the office of the state’s attorney in the judicial district of Ansonia-Milford. Shackleton testified that, using parameters that included the defendant’s name, date of birth, gender,
race and social security number, he had conducted searches of state and federal government on-line databases for criminal and motorvehicle records with data matchingthoseparameters. Onthebasisoftheinformation that Shackleton obtained from his database searches, he contacted the court of record in Santa Rosa County, Florida, seeking a certified copy ofdisposition. He was referred to a county records clerk fromwhom he requested the necessary record.15
Adeputyclerkwiththe archives division ofthe Santa RosaCountyClerkofCourtssentShackletonacertified letterexplainingthatbecause ofaFloridalawregarding the retention of documents, the only documentation available with respect to the requested 1996 Florida conviction was an abstract containing the case history detail. The clerk’s signature was marked with a raised seal of the court. Attached to the letter was a copy of the abstract that was certified by the same clerk as a true and correct copy. In addition to docket descriptions, the abstract contained general case information. In particular, it contained entries identifying by name and address the party defendant—the name being the
same as that ofthe defendant in the present case—and indicating, inter alia, the date the offense had occurred, the disposition, the disposition date and the sentence thatwasimposed. Althoughthe abstractdidnotinclude any notation identifying the specific statutoryviolation at issue, amongst the docket descriptions were entries indicatingthat an ‘‘INFORMATION DUI’’ had been filed and that, following an adjudication of ‘‘GUILTY,’’ the defendant’s driver’s license had been suspended, and he had been ordered to attend ‘‘DUI SCHOOL.’’
The defendant objected to the admission of the abstract arguing, inter alia, that it contained inadmissible hearsay and violated his constitutional rights under the confrontation clause because the person that had preparedtheabstractwasnotavailableforcross-examination. The state argued that the abstract should be admittedbecauseitwasaself-authenticatedpublicdocument. The court overruled all objections to the admissibilityofthe abstractbasedonthefactthattheabstract
was a court document certified by a clerk of the court under seal. Generally, as set forth in part I of this opinion, a court’srulingonthe admissibilityofevidence is entitled to great deference and will be overturned only for a clear abuse of discretion. See State v. Williams, supra, 146 Conn. App. 124. ‘‘[T]o the extent a trial court’s admission of evidence is based on an interpretation of the Code ofEvidence [however], ourstandardofreview is plenary. For example, whether a challenged statementproperlymaybe classifiedashearsayandwhether
ahearsayexceptionproperlyisidentifiedarelegalquestions demanding plenary review. They require determinations about which reasonable minds may not differ; there is no ‘judgment call’ by the trial court, and the trial court has no discretion to admit hearsay in the absence of a provision providing for its admissibility.’’ State v. Saucier, 283 Conn. 207, 218, 926 A.2d 633 (2007). ‘‘Hearsay is an out-of-court statement offered to prove the truth of the matter asserted and is generally inadmissible unless an exception to the hearsay ruleapplies.’’ State v. Calderon, 82 Conn. App. 315, 321, 844 A.2d 866, cert. denied, 270 Conn. 905, 853 A.2d 523, cert. denied, 543 U.S. 982, 125 S. Ct. 487, 160 L. Ed. 2d 361 (2004); see also Conn. Code Evid. § 8-2 (‘‘[h]earsay is inadmissible, except as provided in the Code, the General Statutes or the Practice Book’’). Section 8-3 (7) of the Connecticut Code of Evidence codifies our common-law hearsay exception applicable to public records and reports. Conn. Code Evid. § 8-3, commentary. ‘‘The public records exception to the hearsay rule is based upon the fact that the [record] of the public official can be relied upon for its trustworthiness. The public official may act only occasionally, but when he does act he knows and feels that he is acting under the sanction ofhis official place. Experience has led to the conclusion that it is ordinarily safe to rely upon the trustworthiness ofa [record] made under such circumstances.’’ (Internal quotation marks omitted.) State v. Calderon, supra, 322. ‘‘Although Connecticut has neither precisely nor consistently defined the elements comprising the common-law public records exception to the hearsay rule

. . . [§] 8-3 (7) gleans from case lawthree distinctrequirements forsubstantive admissibility.’’ (Citationsomitted.) Conn. CodeEvid. § 8-3, commentary. Specifically, it is the burden of the party offering the evidence to show that ‘‘(A) the record, report, statement or data compilation was made by a public official under a duty to make it, (B) the record, report, statement or data compilation was made in the
course of his or her official duties, and (C) the official
or someone with a duty to transmit information to the official had personal knowledge of the matters contained in the record, report, statement or data compilation.’’ Conn. Code Evid. § 8-3 (7). ‘‘[I]t is generally recognized that public documents
can be authenticated simply by showing [that] the record purports to be a public record and comes from the custody of the proper public office.’’ (Emphasis added; internal quotation marks omitted.) State v. Calderon, supra, 82 Conn.App. 322, citingC. Tait, Connecticut Evidence (3d Ed. 2001) § 9.4.2, pp. 757–58. Further, General Statutes § 52-165 provides in relevant part that ‘‘[t]he entries or records of all corporations and all public offices, where entries or records are made of their acts, votes and proceedings, by some officer appointed for that purpose, may be proved by a copy certified under the hand of such officer, and the seal of such corporation or office, if any

. . . . ’’ See also Conn. CodeEvid. § 9-1 (b) (no extrinsic evidencenecessary ‘‘if the offered evidence is self-authenticating in accordance with applicable law’’). Rules governing the authenticationofdocuments, however, arenotaproper substitute for a valid hearsay exception. See Wright v. Hutt, 50 Conn. App. 439, 446–47, 718 A.2d 969, cert. denied, 247 Conn. 939, 723 A.2d 320 (1998). ‘‘An official certificate simply authenticates a document, that is, itprovesthatitiswhatitpurportstobe. Itisnotahearsay exception thatpermits the contents ofa certified document to be used to prove the truth of the matter asserted. Anyandallassertions offactcontainedwithin
a certified document must be proven bythe usual rules of evidence and must satisfy the hearsay rule or its exceptions.’’ C. Tait & E. Prescott, Connecticut Evidence (5th Ed. 2014) § 9.12.3, p. 698. Here, the state sought to admit the abstract as substantive evidence thatthe defendanthad aprior conviction for driving a motor vehicle while under the influence in Florida. No argument was made at trial that the data entries on the abstract were not being admitted for the truth ofthe matter asserted and, thus, that the entries were not hearsay statements. Rather, in response to the defendant’s objection that the information contained in the abstract was hearsay, the state argued only that the document was properly authenticated and admissible as apublic record. The defendant argued to the trial court, as he does on appeal, that the state had failed to show that the foundational requirements set forth in § 8-3 (7) ofthe Connecticut Code of Evidence were satisfied.
The trial court ruled that because the abstract was
a court document under seal and certified by the clerk ofthatcourt,thestatehadaddressedallconcernsraised by the foundational requirements in § 8-3 (7) of the Connecticut Code of Evidence. Although the seal and certification served as proof of the authenticity of the abstract, authenticity was never challenged by the defendant. The court’s ruling suggests that the same elements that serve as indicia ofauthenticity—the seal and certification—also serveto satisfythe foundational elementssetforthin § 8-3 (7)withrespecttothehearsay exception for public records. We can find no legal support for that proposition in the Code of Evidence, in
our statutes or in our case law.
In order to satisfy the requirements set forth in § 8- 3 (7) of the Connecticut Code of Evidence, the state needed to show that the abstract was prepared by a public official under a duty to do so, that the abstract
was prepared in the course of that duty, and that the official either had personal knowledge of the information contained in the abstract or the information was providedby someone with adutyto transmitthat information to the official. In its appellate brief, the state addresses the lack of foundation claim by stating that it was reasonable for the court to have inferred that thefoundationalrequirementshadbeenmet.16The state does not cite to any case law that directly supports the proposition that a trial court is permitted to infer evidentiary foundational requirements. Further, we do not agree that it reasonably can be inferred from either the certification or the seal that the deputy clerk who certified the abstract was the same official responsibleforitspreparation, orthatthe deputyclerk, orsomeone with a duty to transmit evidence to the deputy clerk, had personal knowledge of the information contained
on the abstract.
The state presented only Shackleton’s testimony as
a foundation for the admission of the abstract. Shackleton provided no background information about how
or by whom the abstract was prepared. The state fails to point to any portion of Shackleton’s testimony that could have served as a basis for the court drawing inferences that the foundational requirements of § 8-3 (7) ofthe Connecticut Code ofEvidence had been met.
Because the state failed to meet its foundational burden forthe admission ofthe abstract underthe hearsay exception for public records, we conclude that the abstract was admitted by the court in error. In its brief, the state concedes that the abstract was the only evidence presented that proves the defendant was convicted of driving a motor vehicle under the influence in Florida, and thus, if the abstract was admitted in error, that error was not harmless. We agree. We also agree with the state, however, that because the defendant did not challenge the evidence of the Danbury conviction, there was sufficient evidenceto supportthe allegation in the part B information that the defendant
was ‘‘subject to the enhanced penalties under [§] 14- 227a(g),’’ albeitasasecondtime offender. Accordingly, thejudgment onthe part B informationis reversed only
as to the court’s finding that the defendant was guilty of being a third time offender based on the alleged Florida conviction.
The judgment is reversed only as to the defendant’s conviction as a third time offender under the part B information and the case is remanded with direction to modify his conviction on the part B information to reflect that he is a second time offender and to resentence the defendant accordingly. The judgment is affirmed in all other respects.
In this opinion the other judges concurred.

1 The jury also found the defendant guilty of reckless driving in violation of General Statutes § 14-222; however, he does not challenge his reckless driving conviction in the present appeal.

2 The defendant waived his right to ajury trial on the part B information.

3 Because we reverse thejudgment ofthe court on the part B information

onthebasis ofthe claimedevidentiaryerror, we donotreachthe defendant’s additional claims that the court erroneously determined that the defendant previously had been convicted of violating a Florida criminal statute, Fla. Stat. § 316.193 (1999), and that the elements ofthat statute essentially were the same as those of General Statutes § 14-227a.

4 ‘‘The walk and turn test requires the subject to walk heel to toe along

a straight line for nine paces, pivot, and then walk back heel to toe along the line for another nine paces. The subject is required to count each pace aloud from one to nine.’’ (Internal quotation marks omitted.) State v. Popeleski, 291 Conn. 769, 771 n.4, 970 A.2d 108 (2009).

5 ‘‘The one leg stand test requires the subject to stand on one leg with the other leg extended in the air for [thirty] seconds, while counting aloud from [one] to [thirty].’’ (Internalquotationmarks omitted.)Statev.Popeleski,291 Conn. 769, 771 n.5, 970 A.2d 108 (2009).

6 ‘‘The horizontal gaze nystagmus test measures the extent to which a person’s eyes jerk as they follow an object moving from one side of the person’sfieldofvisiontotheother. Thetestispremisedontheunderstanding that, whereas everyone’s eyes exhibit somejerking while turningto the side, when the subject is intoxicated the onset of the jerking occurs after fewer degrees of turning, and the jerking at more extreme angles becomes more distinct.’’ (Internal quotation marks omitted.) State v. Popeleski, 291 Conn. 769, 770 n.3, 970 A.2d 108 (2009).

7 The court did not exclude the evidence on hearsay grounds. Because

we affirm the court’s evidentiary ruling on the basis of the grounds stated by the court, we do not address whether the evidence contained inadmissible hearsay.

8 The state made no objection as to the authenticity of the records.

9 Section 8-3 of the Connecticut Code of Evidence provides in relevant part: ‘‘The following are not excluded by the hearsay rule, even though the declarant is available as a witness

. . . . A statement made for purposes ofobtainingamedicaldiagnosisortreatmentanddescribingmedicalhistory,

orpast orpresent symptoms, pain, orsensations, orthe inception orgeneral character of the cause or external source thereof, insofar as reasonably pertinent to the medical diagnosis or treatment.’’ Because the court did not rule on the hearsay argument in addressing the admissibility ofthe medical records, that issue is not properly before us on appeal.

10 The defendantnever argued before the trial court, as he does on appeal, that evidence of his neck injury would have helped to explain his failure to adequately perform the horizontal gaze nystagmus test, and, therefore,

we do not consider that argument. See State v. Crespo, supra, 114 Conn. App. 366.

11 In addition to the Porter argument, defense counsel also objected to the admissibility of testimony regarding the finger dexterity test on the ground that evidence of another field sobriety test would be cumulative of other evidence supporting the officer’s determination at the time of arrest that the defendant had been intoxicated, namely, that the defendant had failed the horizontal gaze nystagmus test and the walk and turn test, that he refused to participate in the one leg stand test and that he refused a breathalyzer test. The court overruled that objection, noting that the state’s burden ofproof was very high and that it had a right to present to the jury everything that factored into the officers’ decisions at the time ofthe arrest. The defendant does not challenge thataspect ofthe court’s ruling on appeal.

12 Because our disposition of the claim with respect to the abstract is dispositive,wedonotaddresswhetherthefingerprintcardalsowasadmitted in error. The defendant also argues as part ofthis claim that the admission of the abstract and fingerprint card violated his constitutional right to confrontation underboth the federal and state constitutions, although he chose not to briefthe state constitutional claim separately thus abandoning it. See State v. Simpson, 286 Conn. 634, 651 n.17, 945 A.2d 449 (2008). ‘‘This court has abasicjudicial dutyto avoid deciding a constitutional issue ifanonconstitutional ground exists that will dispose ofthe case.’’Moorev. McNamara, 201 Conn. 16, 20, 513A.2d 660 (1986). Because we agree withthe evidentiary aspect ofthe defendant’s claim, we donotreachthe constitutionalquestion.

13 General Statutes § 14-227a (g) provides in relevant part: ‘‘Any person who violates any provision of subsection (a) of this section shall

. . . (2) for conviction ofa second violation within ten years after aprior conviction for the same offense, (A) be fined not less than one thousand dollars or
more than four thousand dollars, (B) be imprisoned not more than two years, one hundredtwentyconsecutive days ofwhichmaynotbe suspended

or reduced in any manner, and sentenced to a period of probation [with statutorilydescribed conditions]; and (3) forconviction ofathird and subsequentviolationwithintenyears afterapriorconvictionforthe same offense, (A) be fined not less than two thousand dollars ormore than eight thousand dollars, (B) be imprisoned not more than three years, one year of which may not be suspended or reduced in any manner, and sentenced to aperiod of probation [with statutorily described conditions], and (C) have such person’s motorvehicle operator’s license ornonresident operating privilege permanently revoked upon such third offense

. . . . For purposes of the imposition of penalties for a

. . . third and subsequent offense pursuant to this subsection, a conviction

. . . in any other state of any offense the essential elements ofwhich are determined by the court to be substantially the same as subdivision (1) or (2) ofsubsection (a) ofthis section orsection 53a-56b or 53a-60d, shall constitute aprior conviction forthe same offense.’’14 It is not a ‘‘condition to the imposition ofenhanced penalties for a third offense, that a defendant must have been convicted previously of being a second time offender.’’ See State v. Surette, 90 Conn. App. 177, 181, 876 A.2d 582 (2005).

15 The state also introduced through Shackleton documentary evidence ofa 2002 conviction of operating a motor vehicle while under the influence prosecuted in the Superior Court in Danbury, including a certified copy of

ajudgment ofconviction and arelated fingerprint card. The defendant does not challenge the admissibility of that evidence on appeal.

16 The state argues in the alternative that the court was permitted to consider hearsay evidence because it was acting as a sentencing court with respect to the part B trial. We find no merit in this argument. Sentencing cannot occur until both parts ofthe information have been adjudicated. See State v. Jones-Richards, 271 Conn. 115, 123, 855 A.2d 979 (2004). Adjudication of part B of an information is no less of a trial than the proceedings

on the first part of the information; the state has the burden of proving a violation beyond a reasonable doubt and all evidentiary rules regarding the admission of evidence are the same.
