OPINION ON MOTION FOR REHEARING
We overrule appellant Weingarten Realty Investors’s motion for rehearing. We withdraw the opinion issued in this case on May 2, 2002, and we substitute the following opinion in its place.
INTRODUCTION
This is a property-tax-appraisal case involving alleged unequal taxation of commercial property owned by Weingarten Realty Investors. Weingarten appeals the trial court’s judgment in favor of the Harris County Appraisal District (“HCAD”). We affirm the trial court’s judgment.
Factual and PROCEDURAL Background
Weingarten purchased Champion’s Village Shopping Center in December 1998, for $36 million. Champion’s Village is located at FM 1960 and Champion Forest Drive in Houston, Harris County, Texas, and contains approximately 400,000 square feet of net rentable area.
HCAD appraised Champion’s Village Shopping Center at $30 million for the 1999 tax year. Weingarten protested HCAD’s appraisal, and after exhausting its administrative remedies, timely appealed to the district court. In its petition, Wein-garten made two claims of entitlement to relief for the 1999 tax year under the Texas Tax Code. Weingarten contended the appraised value of Champion’s Village Shopping Center was in excess of its fair market value under the Texas Constitution. Weingarten also contended the appraised value was unequal to the appraised values of several comparable properties for purposes of ad valorem taxation. Wein-garten later nonsuited the excessive-valuation appeal and proceeded to trial solely on its unequal-appraisal claim.
Before trial began, HCAD filed a motion to exclude the testimony of Weingarten’s sole expert witness, David Dominy. The motion, filed under
E.I. du Pont de Nemours & Co. v. Robinson,
Rather than conduct a pretrial Robinson hearing, because it was a bench trial, the trial court “carried the motion.” At trial, Dominy testified Champion’s Village was unequally appraised and its equal-appraised value was $19,149,962 — more than $10 million less than HCAD’s 1999 appraisal. At the conclusion of the one-day bench' trial, the trial court requested post-trial briefs in lieu of closing arguments. Along with its brief, Weingarten submitted additional evidence for purposes of HCAD’s Robinson challenge — the affidavits of Breck Bostwick and Ronald Little. About six weeks after the trial, the court entered an order excluding the testimony of Dominy and simultaneously signed a take-nothing judgment against Weingarten. Weingarten filed a motion to reconsider and motion for new trial. The motion for new trial was overruled by operation of law, and after a hearing on the motion to reconsider, the trial court entered no further orders.
Issues PResented
Weingarten presents three issues for review:
(1) Did the trial court abuse its discretion in excluding Weingarten’s expert witness by misinterpreting and misapplying section 42.26(d) of the Texas Tax Code?
(2) Does Robinson apply to the trial court’s exclusion of Dominy’s testimony, and if it does, did the trial court abuse its discretion in excluding Dominy’s testimony under Robinson?
(3)Is Weingarten entitled to an award of reasonable attorney’s fees?
Standard of Review
We review an order excluding an expert witness under an abuse-of-discretion standard.
Helena Chem. Co. v. Wilkins,
The trial court did not enter findings of fact or conclusions of law. Therefore, we view the trial court’s judgment as impliedly finding all the facts necessary to support its judgment.
See Worford v. Stamper,
Analysis
We begin by addressing HCAD’s contention that Weingarten waived a portion of the argument it now brings on appeal. In its motion to exclude expert testimony, HCAD attacked the reliability
*284
of Dominy’s foundational data. On appeal, HCAD argues Weingarten waived review as to HCAD’s argument that Dominy’s calculations are unreliable because they are based on only portions of comparable retail centers. HCAD claims Weingarten did not specifically address this argument in its original brief. We disagree. As Weingarten points out in its reply brief, appellate courts treat an issue or point as covering every subsidiary question that is fairly included in the issue or point.
See
Tex.R.App. P. 38.1(e);
see also Stephenson v. LeBoeuf,
Is an expert witness insulated from a Robinson reliability challenge when a statute mandates the methodology?
In its second issue, Weingarten argues that an expert witness is insulated from a
Robinson
reliability challenge when a statute mandates the methodology used by the expert. Weingarten cites
Rushing v. Kansas City S. Ry. Co.,
Did the trial court abuse its discretion in excluding Dominy’s testimony under Robinson ?
Unreliable expert testimony is of no evidentiary value.
See Havner,
The trial court’s gate-keeping function does not supplant cross-examination as the “traditional and appropriate means of attacking shaky but admissible evidence.”
Id.
at 728. The availability of cross-examination, however, does not relieve the trial court of its threshold responsibility under Rule 702 to ensure that an expert’s testimony both rests on a rehable foundation and is relevant to the task at hand.
Id.
In ruling on reliability, the trial court is not to determine whether the expert’s conclusions are correct; rather, it determines whether the expert’s analysis is rehable.
Robinson,
In
Robinson,
the Texas Supreme Court identified six nonexclusive factors to determine whether an expert’s testimony is rehable and thus admissible.
See Robinson,
In this case, because the trial court carried HCAD’s motion to exclude, Dominy testified as if his opinions were admitted evidence. The main avenue for HCAD to challenge the reliability of Domi-ny’s testimony was on cross-examination; on appeal, this does not mean that Domi-ny’s testimony can only be chahenged by suffieiency-of-the-evidence issues as opposed to admissibility. In its cross-examination, HCAD extensively chahenged the foundational data Dominy used in making his unequal-appraisal calculations. HCAD demonstrated the “comparable properties” Dominy used to perform his equal-and-uniform valuation analysis were questionably “comparable” and questionably “appropriately adjusted” for several reasons such that any opinion drawn from them would be unreliable. During its cross-examination of Dominy, HCAD showed:
• Dominy’s “comparable properties” were significantly smaller retail centers with 105,897 to 258,513 of square feet of improvements compared to the 407,013 square feet of improvements in Champion’s Village Shopping Center;
• Nine of the ten “comparable properties” used had per-square-foot appraised values significantly lower than Champion’s Village;
*286 • Dominy used only ten “comparable properties” even though there were 191 retail centers existing in the northwest quadrant of Harris County, where Champion’s Village Shopping Center was located;
• Dominy carved out portions of the comparable retail centers due to disparate ownership and, in fact, used only portions of the “comparable properties” selected in his equal-and-uniform analysis;
• The adjustments Dominy made to the “comparable properties” considered only physical characteristics of condition, age, size and location; and
• The amount of the percentage adjustment for each characteristic of the “comparable properties” that differed from Champion’s Village was subjective.
This testimony constitutes a sufficient basis for the trial court to have rejected Dominy’s testimony as unreliable, based upon the quality of the “comparable properties.” Though not unbridled, the trial court had great latitude in ruling on the admissibility of an expert appraiser’s testimony based upon underlying facts or data.
See, e.g., Pape v. Guadalupe-Blanco River Auth.,
Did the trial court exclude Dominy’s testimony based on an improper interpretation and application of section 42.26(d) of the Texas Tax Code?
In its first issue, Weingarten argues the trial court abused its discretion in interpreting and applying section 42.26(d) of the Texas Tax Code to exclude Weingar-ten’s expert testimony. Essentially, Weingarten claims the trial court rejected the methodology of the statute if it excluded Dominy. We begin with a review of the statute and this court’s opinion in
Harris County Appraisal Dist. v. United Investors Realty Trust,
In 1997, the Texas Legislature enacted section 42.26(d) of the Texas Tax Code, which states:
The District Court shall grant relief on the ground that a property is appraised unequally if the appraised value of the property exceeds the median appraised value of a reasonable number of comparable properties appropriately adjusted.
Tex. Tax Code § 42.26(d). In order to perform the calculation under this statute, the appraisal expert determines a reasonable number of comparable properties. Then, the expert takes the appraised value of those properties from the public record, and appropriately adjusts them to the subject property. Thereafter, the appropriately adjusted comparable properties are arrayed and a median is determined.
United Investors Realty Trust,
*287
In
United Investors Realty Trust,
this court noted that section 42.26(d) became law on January 1, 1998, enacted as part of the Taxpayer’s Bill of Rights.
See id.
at 652. It was intended to facilitate tax remedies for property owners.
Id.
In using the methodology mandated by this new avenue for
ad valorem
tax relief, this court rejected any requirement of independent market-value appraisals of comparable properties, appraisal ratios, or a statistical sample of comparable properties.
See id.
at 658. The proper application of section 42.26(d) does not mandate consideration of market value.
Id.
at 654. Weingarten and HCAD have made several arguments to the trial court, similar to issues presented in
United Investors Realty Trust.
These arguments question the proper interpretation of the Texas Tax Code and what factors an expert appraisal witness should consider in forming an unequal-appraisal opinion. HCAD asserts that section 42.26(d) requires consideration of independent market value of comparable properties. This court rejected that argument in
United Investors Realty Trust. See id.
at 658. By statute, appraised value is market value.
See
Tex. Tax Code § 23.01(a). Furthermore, if a conflict exists between taxation at market value and equal and uniform taxation, equal and uniform taxation must prevail.
United Investors Realty Trust,
Dominy’s methodology complied with section 42.26(d). Counsel for Weingarten systematically led Dominy through the statute as Dominy made his calculations to form opinions of unequal appraisal and a value for an equal appraisal. There was nothing about his methodology that contravened section 42.26(d). See id. Many of HCAD’s arguments in its motion to exclude in the trial court were not proper grounds for exclusion of Domin/s testimony; however, the lack of a reliable foundation under Robinson was a proper objection, and, as discussed above, the trial court did not abuse its discretion in excluding Dominy’s testimony on that basis.
Nothing in the record indicates the trial court rejected the methodology of section 42.26(d). There are no findings of fact or conclusions of law. Therefore, this court must affirm the judgment if it can be upheld on any legal theory that finds support in the evidence.
See Curtis v. Comm’n for Lawyer Discipline,
Was Weingarten entitled to attorney’s fees?
Finally, in its third issue, Weingarten argues it was entitled to an award of attorney’s fees. Because Weingarten has not prevailed in this case, it is not entitled to attorney’s fees under the Texas Tax Code. See Tex. Tax Code § 42.29; Dallas Cent. Appraisal Dist. v. Seven Inv. Co., 835 *288 S.W.2d 75, 79 (Tex.1992). Accordingly, we overrule Weingarten’s third issue.
We affirm the trial court’s judgment.
