OPINION
Petitioner Traci Miskel appeals the district court’s denial of her petition for a *449 writ of habeas corpus under the Anti-Terrorism and Effective Death Penalty Act (“AEDPA”), 28 U.S.C. § 2254. Petitioner, who was convicted of driving while having a breath alcohol concentration of 0.10 percent or more, in violation of ohio Rev. Code § 4511.19(A)(3) (1998), 1 challenges the trial court’s .decisions to prohibit cross examination and the presentation of expert testimony on whether the type of breath testing machine used to test Petitioner is generally reliable. Specifically, she asserts that the trial court’s rulings on these issues violated her Sixth. Amendment rights to confrontation and compulsory process and her Fourteenth Amendment rights to present a complete defense and to have the state prove each element of the offense beyond a reasonable doubt. 2 For the following reasons, we AFFIRM the district court’s denial of the writ.
I. BACKGROUND
On September 7, 1998, the state of Ohio charged Petitioner Traci Miskel with Operating a Motor Vehicle While Under the Influence (“OMVI”), in violation of ohio Rev. Code § 4511.19(A)(1) (1998)

, Operating a Motor Vehicle With a Prohibited Concentration of Alcohol (“OMVI
per se
”), in violation of § 4511.19(A)(3) (1998), and speeding, in violation of ohio Rev. Code § 4511.21(C). A jury in Franklin County Municipal Court convicted Petitioner of OMVI
per se
and speeding but acquitted her of OMVI. The sole elements of OMVI
per se
are (1) operating a vehicle (2) while having “a concentration of [0.10 grams] or more by weight of alcohol per 210 liters of breath.”

ohio Rev. Code § 4511.19(A)(3). A traditional OMVI charge, by contrast, requires the prosecution to prove that' the defendant was in fact under the influence while driving; the defendant’s breath alcohol concentration (“BAC”) is not an element of OMVI, but it creates a rebuttable presumption that he was under the influence. § 4511.19(A)(1);
State v. Vega,
During the trial,. at which Respondent the Honorable Dwayne Maynard presided, Petitioner sought to cross examine the police officers who performed her breath test, Officers Robert Wetzel and Robert McKelvey, on whether the device they used to measure Petitioner’s BAC, the BAC Verifier, is accepted by the scientific community as generally reliable. Petitioner also proffered the expert testimony of Dr. Henry Shamansky, who would testify that the BAC Verifier has come under criticism within the scientific community. Specifically, Petitioner sought to show that the BAC Verifier is susceptible to interference from radio waves and that its conversion ratio from breath alcohol content to blood alcohol content has come into question among scientists.
Judge Maynard denied both requests on the grounds that the general reliability of the BAC Verifier was not a relevant issue in the trial. Judge Maynard based this ruling on the Ohio Supreme Court’s decision in
State v. Vega,
On appeal to the Ohio Court of Appeals for the Tenth District, Petitioner asserted that Judge Maynard’s decision to preclude a foray into the general reliability of the BAC Verifier was a violation of her Sixth Amendment rights to confrontation and compulsory process and her Fourteenth Amendment rights to present a complete defense and to be convicted only upon proof beyond a reasonable doubt. The appeals court acknowledged that
Vega
involved a traditional OMVI charge — where the defendant’s BAC is critical evidence, but not an element of the crime — but concluded that the case was nevertheless controlling in Petitioner’s OMVI
per se
trial and affirmed her conviction.
State v. Miskel,
No. 99AP-482,
The Supreme Court of Ohio dismissed Petitioner’s appeal as not involving any substantial constitutional question and, on February 1, 2001, she filed this petition for a writ of habeas corpus pursuant to 28 U.S.C. § 2254 in the Southern District of Ohio. It is the district court’s denial of the writ that Petitioner now appeals. As a result of a stay of execution of her sentence during the appeals and habeas process, Petitioner has not served any of the sentence, to wit, 180 days in the Franklin County jail, 177 days suspended for 1 year of probation, and 3 days in an alcohol rehabilitation program. J.A. at 6. Nevertheless, Petitioner is in “custody” within the meaning of 28 U.S.C. § 2254 and therefore has standing to bring this habeas action.
See McVeigh v. Smith,
*451 On appeal to this Court, Petitioner presents the same arguments she has advanced throughout — that the state courts’ adherence to Vega denied her the right to meaningfully cross examine key state’s witnesses; to compel witnesses to testify in her favor; to present a meaningful defense; and to be presumed innocent until the prosecution proves each element of the crime beyond a reasonable doubt. Brief of Appellant at 8. We address Petitioner’s arguments in turn.
II. STANDARD OF REVIEW
In a habeas corpus proceeding, this Court reviews the district court’s legal conclusions
de novo
and its factual findings for clear error.
E.g., Vincent v. Seabold,
As a threshold matter, a legal doctrine is not “clearly established Federal law, as determined by the Supreme Court” unless it is based on “holdings, as opposed to the dicta, of the Court’s decisions as of the time of the relevant state-court decision.”
Williams v. Taylor,
III. DISCUSSION
Initially, we note that the standard of review established by AEDPA is determinative in this case. As debatable as Vega may be, 6 we conclude that its application in Petitioner’s case was not contrary to or an unreasonable application of clearly established federal law.
A. Confrontation Clause
The first issue we address is whether the trial court’s decision to prohibit cross examination on the issue of the BAC Verifier’s general reliability was contrary to or an unreasonable application of clearly established federal law.
Petitioner asserts that the trial court violated her right “to be confronted with the witnesses against [her],” U.S. Const.
*452
amend. VI, by precluding cross examination of Officers Wetzel and McKelvey on the issue of whether the BAC Verifier is generally reliable. Brief of Appellant at 24. The trial court did permit Petitioner to cross examine the officers on whether they properly administered the breath test, whether they complied with the Ohio Health Department’s mandatory guidelines for operating the test, and whether the specific machine used to test Petitioner was functioning properly and reliably. In upholding the trial court’s limitation of cross examination to only these issues, the appeals court reasoned that
Vega
stands for the proposition that the
general
reliability of the BAC Verifier machine is irrelevant.
Miskel,
In reviewing the Ohio courts’ decisions in this case, we note that the Supreme Court has not confronted a challenge to limits on cross examination imposed pursuant to an OMVI statute or an OMVI
per se
statute. Still, there is important Supreme Court precedent relevant to Petitioner’s confrontation clause claim. An essential component of the confrontation clause is the accused’s right to cross-examine the state’s witnesses.
Davis v. Alaska,
In addition, it is the state’s prerogative to define what evidence is relevant to the case in the first place.
See Jackson v. Virginia,
In sum, Petitioner had a full and fair opportunity to' challenge the credibility and reliability of the state’s witnesses by inquiring as to their qualifications and knowledge about the specific machine’s competence during the test performed on Petitioner. Consequently, the limits on cross examination imposed by the trial court did not disable Petitioner from attacking the accuracy and reliability of the specific BAC Verifier used to measure her BAC. Because Petitioner had an “opportunity for effective cross examination,”
Fensterer,
B. Compulsory Process and the Right to Present a Defense
The next issue we consider is whether the trial court’s refusal to admit expert testimony on the issue of the BAC Verifier’s general reliability was contrary to or an unreasonable application of clearly established federal law.
Under AEDPA, if there is
no
“clearly established Federal law, as determined by the Supreme Court” that supports a habeas petitioner’s legal argument, the argument must fail.
See
28 U.S.C. § 2254(d)(1);
Taylor,
As. authority for her claim, Petitioner relies solely on
California v. Trombetta,
The materiality of breath samples is directly related to the reliability of the Intoxilyzer [a breath testing machine] itself. The degree to which preserved samples are material depends on how reliable the Intoxilyzer is. This correlation suggests that a more direct constitutional attack might be made on the sufficiency of the evidence underlying the State’s case. After all, if the Intoxi-lyzer were truly prone to erroneous readings, then Intoxilyzer results without more might be insufficient to establish guilt beyond a reasonable doubt.
Id.
at 489 n. 10,
There are two serious flaws with Petitioner’s reading of
Trombetta.
First, assuming Petitioner is correct to read such significance into a footnote of a Supreme Court opinion, the Court’s subsequent description of what the purported constitutional right entails undermines her argument. To impeach the machine’s credibility, the Court observed in
Trombetta,
the defendants could have inspected the machine and its calibration results.
Thus to the extent the Trombetta Court contemplated a constitutional right to challenge a breath test’s reliability, the right it constructed is plainly targeted at the specific testing machine in question; indeed, the Court makes no mention of attacking the general reliability of a certain model of testing device. Consequently, Trombetta is not inconsistent with State v. Vega and Ohio’s OMVI per se regime. Petitioner does not suggest that the court precluded her from showing that the specific location where her breath test occurred, the police station, is particularly vulnerable to radio wave interference or that the BAC Verifier used to test her did in fact encounter such interference. Petitioner’s proffer of Dr. Shamansky’s testimony was phrased by *455 counsel as addressing the machine’s “general scientific reliability.” J.A. at 713. In any event, Petitioner’s counsel did question officer McKelvey about whether he checked for radio wave interference prior to conducting the test on Petitioner. Id. at 698-702. Petitioner’s counsel also inquired whether the specific machine used to test Petitioner provides accurate results. Id. at 670-71, 702.
The second flaw with Petitioner’s reading of
Trombetta
is that it is based on
dicta,
rather than the Court’s holding, which was that the state need not preserve breath sample results when it intends to introduce the results of a breath test at trial.
Trombetta,
We note in closing that the district court relied on a more recent decision of the Supreme Court to deny Petitioner’s claim that the trial court denied her the right to present a defense.
See United States v. Scheffer,
In sum, we hold that the trial court’s refusal to admit Petitioner’s proffered expert testimony on the issue of the BAC Verifier’s general reliability was not contrary to, nor an unreasonable application of, clearly established Federal law. 28 U.S.C. § 2254(d)(1);
Taylor,
C. Unconstitutional Presumption
The final issue we consider is whether the trial court required the jury to presume that the result of Petitioner’s breath test was accurate, thereby enabling the state to avoid its constitutional obligation of proving, beyond a reasonable doubt, that Petitioner’s BAC exceeded 0.10. See ohio Rev. Code § 4511.19(A)(3) (1998).
Presumptions are evidentiary devices that enable a factfinder to presume the existence of an “ultimate” or “elemental” fact upon proof of “evidentiary” or “basic” facts.
County Court of Ulster v. Allen,
It is fair to say that the Supreme Court has viewed mandatory presumptions in criminal cases with much skepticism.
See, e.g., Sandstrom v. Montana,
Thus the statute does not create a presumption on its face; yet Petitioner asserts that the trial judge’s evidentiary rulings created one in effect. Petitioner’s argument runs as follows: The Ohio Supreme Court’s holding in Vega, and the court’s application of it in Petitioner’s case “establish[ ] an unconstitutional presumption that the machine was reliable and the test result was accurate.” Brief of Appellant at 41. The jury, however, was not instructed to presume Petitioner’s guilt of the offense on the basis of the breath test. Moreover, contrary to Petitioner’s assertion that Vega removed the issue of a breath test’s reliability from the factfin-der’s domain, the specific machine’s reliability was very much an issue at Petitioner’s trial. Indeed, Petitioner’s counsel cross-examined officers Wetzel and McKel-vey on this issue. Finally, the judge’s instruction to the jury commits the issue of the test’s reliability to the jury’s judgment and plainly places the entire burden on the prosecution:
Before you can find this defendant guilty, you must find,- beyond a reasonable doubt, that ... the defendant operated a vehicle ... with a concentration of [.10 grams] or more by weight of alcohol per 210 liters of breath. The facts in this case allege a test of .115 of one gram by weight of alcohol per 210 liters of her breath.... I have admitted the results of a chemical test administered to the defendant to determine the concentration of alcohol in her system. You must evaluate all the evidence pre *457 sented regarding the test and its accuracy.
If you find that the State, in this case, proved beyond a reasonable doubt all the essential elements of [sic] offense of operating a vehicle with a prohibited concentration of alcohol in her system, your verdict in this case must be guilty. If you find that the State failed to prove beyond a reasonable doubt any of the essential elements of the offense ... then your verdict must be not guilty.
J.A. at 859-60 (instructions to the jury). In view of these realities, we cannot conclude that the jury was encouraged to presume any particular fact, let alone an elemental or ultimate one.
Nor are we persuaded by Petitioner’s reliance on a Ninth Circuit case in which the court struck down the application of a Nevada OMVI statute in a manner that established a mandatory conclusive presumption.
See McLean v. Moran,
We are better guided by a recent decision of the Tenth Circuit, in which the court upheld an OMVI
per se
ordinance against a habeas petitioner’s assertion that it created an unconstitutional presumption.
Welch v. City of Pratt,
In conclusion, we re-emphasize the significance in this case of the highly deferential AEDPA standard of review. Petitioner relied exclusively on a distinguishable Ninth Circuit case from the pre-AEDPA era to support her claim that her conviction resulted from an unconstitutional presumption. Because this is not “clearly established Federal law, as determined by the Supreme Court,” 28 U.S.C. § 2254(d)(1), we must affirm the district court’s dismissal of this claim as well.
IV. CONCLUSION
For the foregoing reasons, we AFFIRM the district court’s denial of the writ.
Notes
.With an effective date of January 1, 2004, Ohio reduced the minimum breath alcohol concentration to 0.80 percent and redesignat-ed § 4511.19(A)(3) as § 4511.19(A)(1)(d). See ohio Rev. Code § 4511.19, Historical and Statutory Notes (2004). Throughout this opinion, we refer to the 1998 version of the statute because it was in effect at the time Petitioner was charged and convicted.
. The district court granted a certificate of appealability as to all of Petitioner's claims.
. Now redesignated as § 4511.19(A)(1)(a). See ohio Rev. Code § 4511.19, Statutory and Historical Notes (2004).
. Petitioner's breath alcohol concentration (‘'BAC”) was measured as 0.115.
. Petitioner originally named as respondents James A. Karnes, the Franklin County Sheriff,
*451
and Judge Maynard. The magistrate judge found that Sheriff Karnes was not a proper respondent because he did not have custody over Petitioner.
See Reimnitz v. State’s Attorney,
. See Stephen E. Palmer, State v. Vega and Ohio’s OMVI Law: Per Se Unconstitutional, 24 CAP. U.L. REV. 687 (1995) (arguing that Vega is unconstitutional because it infringes on the right to present a defense).
. The Ohio appeals court did not appear to recognize a distinction between OMVI
per se,
the crime at issue in Petitioner's case, and traditional OMVI, the crime at issue in
Vega.
As discussed
supra,
OMVI requires proof that the defendant was under the influence of alcohol while driving; to establish this element, the prosecution relies on the defendant's BAC measurement, which creates a rebuttable presumption that he was under the influence.
See Vega,
. Petitioner does not challenge the constitutionality of the OMVI
per se
statute. Consequently, the question whether Ohio may constitutionally proscribe the act of driving with a BAC in excess of 0.10 is not before us.
See Jackson,
. We observe that this Court has upheld the use of a similar presumption where the judge made it clear to the jury that the presumption was rebuttable.
