[¶ 1.] Richard and Melva Beals appeal the trial court’s ruling that the hearing examiner’s decision did not overturn the county’s valuation of Beals’ property and thus, Beals are not entitled to a refund of 1999 taxes, which were paid according to the County’s initial valuation. We affirm.
FACTS
[¶ 2.] Richard and Melva Beals own real estate in Day County. This real estate was previously classified as non-agri-eultural land for real estate tax purposes but was vacated and reclassified as agricultural land in June of 1998. However, these changes were not properly recorded with the Register of Deeds until February of 1999. This resulted in the property being classified as non-agricultural property by the Day County Director of Equalization for the year 1999 and real estate taxes were calculated accordingly. Beals appealed the tax assessment to the South Dakota Department of Revenue. They contended that it was an error for the County to use the non-agricultural classification rather than the agricultural classification when calculating Beals’ taxes. They further contended that as a result of the incorrect classification, the County’s valuation of the real estate was in excess of its full and true value. A hearing was held and the hearing examiner issued a decision requiring the property to be “reclassified as agricultural property, if not already, and value[d] as such”. The decision also contained a conclusion of law stating:
Petitioners bear the burden of producing sufficient evidence to demonstrate that the assessed valuation of their property was in excess of its full and true value. Petitioners did not meet that burden.
Neither party appealed the decision. Pursuant to the decision, Day County reclassified the property as agricultural for the year 1999 and adjusted the tax accordingly.1 Day County did not alter the original valuation of the property because the County maintained that the original valuation had not been overturned by the hear*417ing examiner’s decision. Beals paid the tax demanded under protest and filed a claim in the Fifth Judicial Circuit Court against Connie Wagner, Day County Treasurer, for recovery of the alleged 'wrongfully collected tax.2 Beals claim that in addition to reclassification, the original valuation of the property had been overturned and revaluation of their property was required by the hearing examiner’s decision. Beals further claim the revaluation would have reduced their 1999 real estate taxes and entitled them to a refund.
[¶ 3.] At trial, Beals’ refund claim was combined with two appeals involving Day County’s valuation of Beals’ real property for years 2000 and 2001. The two appeals and the refund claim were tried together. The two appeals were dismissed pursuant to Stipulation and Agreement of the parties, leaving only the matter of the refund claim for the trial court.3
[¶ 4.] The trial court dismissed the refund claim. It found the hearing examiner’s decision affirmed the county’s original valuation and did not require revaluation of the reclassified property and thus, the Day County Treasurer committed no error in calculating and collecting the taxes owed by Beals. Beals appeal.
STANDARD OF REVIEW
[¶ 5.] At issue is the interpretation of and compliance with the decision of the hearing examiner. The former is a question of law and the latter is a mixed question of law and fact and both are reviewed de novo. Erdahl v. Groff, 1998 SD 28, ¶ 15, 576 N.W.2d 15, 18; Matter of Groseth Intern., Inc., 442 N.W.2d 229, 232 (S.D.1989); Permann v. South Dakota Dept. of Labor, 411 N.W.2d 113, 115-17 (S.D.1987).
ISSUES
I. Whether the trial court erred in determining Beals were not entitled to a refund under the hearing examiner’s decision.
II. Whether stipulations made as to the valuation of the real estate in question applied to the calculation of real property taxes due for 1999.
DECISION
Interpretation of the Hearing Examiner’s Decision
[¶ 6.] The source of this dispute lies primarily in the parties’ different interpretations of the hearing examiner’s decision. Neither party appealed the decision, thus making it final as to the issues it addressed. This Court has held, “[I]f the prior final judgment or order has been rendered by a court of competent jurisdiction, it ‘is conclusive as to all rights, questions, or facts directly involved and actually, or by necessary implication, determined therein,’ whether the court was correct at the time or not.” Moe v. Moe, 496 N.W.2d 593, 595 (S.D.1993) (quoting Raschke v. DeGraff 81 S.D. 291, 295-96, 134 N.W.2d 294, 297 (1965)). This Court has further held, “[A]ny claim over which an administrative agency had jurisdiction that is raised and rejected by the agency, is subsequently barred from being retried on the merits in the courts under the doctrine of res judicata.” McElhaney v. Anderson, 1999 SD 78, ¶ 13, 598 N.W.2d 203, 206. The parties had the right to appeal but did *418not do so. Thus, res judicata applies and the decision of the hearing examiner is final and binding. Only the meaning and enforcement of the decision are at issue here.
[¶ 7.] Although the hearing examiner’s decision is not the perfect example of clarity, we conclude that the decision affirmed the County’s original valuation of Beals’ property, and did not require revaluation. The stated issue in the decision was whether “the subject property [was] assessed higher than actual market value or assessed higher than comparable property”. Under South Dakota law at the time of the hearing, there was a presumption that the County’s assessment was correct.4 See Kocer v. Bon Homme County Com’rs, 1999 SD 155, ¶ 14, 604 N.W.2d 1, 4; Clarkson and Co. v. Harding County, 1998 SD 74, ¶ 6, 581 N.W.2d 499, 502; Richter Enter., Inc. v. Sully Cty., 1997 SD 61, ¶ 7, 563 N.W.2d 841, 843.
[¶ 8.] The hearing examiner placed the burden of overcoming this presumption on the taxpayers, Beals, as required by our law at that time. Id. Based on the evidence presented, the hearing examiner concluded Beals had not met the burden of overcoming the presumption in favor of the County’s assessment; consequently, the County’s valuation was not overturned. However, the hearing examiner did find portions of the property were improperly classified as non-agricultural and ordered those portions to be reclassified as agricultural. The order stated:
It is the order of the Hearing Examiner that the following shall be reclassified as agricultural property, if not already, and value as such.
The phrase “value as such” as used in this order, gives rise to the dispute in this case.
[¶ 9.] Beals contend this phrase meant the County’s original assessment was incorrect, and that a new valuation was required. Standing alone, this language could reasonably be interpreted to require revaluation. However, when the decision is read as a whole, it is clear that revaluation was not required because the hearing examiner had found that Beals failed to meet their burden of proving the original assessment was incorrect.
[¶ 10.] The relevant statement in the decision is contained in the conclusions of law. It reads:
Petitioners bear the burden of producing sufficient evidence to demonstrate that the assessed valuation of their property was in excess of its full and true value. Petitioners did not meet that burden.
(emphasis added). The meaning and intent of the conclusion is clear and unambiguous: the petitioners did not meet their burden of proving the County’s assessed value was wrong. To interpret the language of the order — “value as such”- — as requiring a new assessment would be in direct conflict with the decision’s unambiguous conclusion of law. Beals’ proposed interpretation of the decision would mean the hearing examiner concluded the original valuation was not excessive or erroneous but then ordered a revaluation anyway. The hearing examiner could not have intended such an inconsistent ruling. The hearing examiner’s order did not require the County to revalue the property. Any other interpretation of the decision would create an inconsistency between its provisions.
*419 Property Value Stipulations
[¶ 11.] Alternatively, Beals claim the parties’ oral and written property value stipulations are binding and enforceable in its refund claim. The oral stipulation was made before the trial court took evidence in the combined trial of the appeals and the refund claim. That stipulation concerned the valuation of the real estate involved in the three matters. Following is the stipulation as presented to the trial court:
MR. SMEINS [attorney for appellee, Day County]: Your honor, it is our position that the value of the property apparently is at issue in all three proceedings. We’ve raised the issue whether the value can be re-determined and the Court can take that under advisement. We can file briefs and motions. But the issue of valuation we would stipulate that the value the Court determines for '99, 2000, and 2001 would all be the same in all three. Three matters.
MR. COESTER [attorney for appellants, Beals]: We would stipulate to that.
MR SMEINS: Then the court can rule on the refund action based on whether or not it can be re-valued but for 2000 and 2001 the issue is the same, it’s simply what’s the value of the unplatted property as ag- — ag classification.
THE COURT: Well, again, I’m not sure exactly what you are referring to because I don’t know anything about this case. What values are you stipulating to?
MR SMEINS: Your Honor, what we say, whatever the — the issue in the two appeals, appeals that have been made is the — is the value of the property as ag property. The issue in the refund action, according to the way they brought for them to prevail they have to redetermine the value of the property that the county did not value properly. Whatever value, we would agree that it’s the same for all three years. Whatever you decide.
MR COESTER: And we agree to that.
[¶ 12.] The parties stipulated that the land values used in each matter (both the appeals and the claim) should be the same. However, it is clear from the record that Day County did not concede revaluation was required in the refund claim. Day County preserved its position that the original valuation was not overturned by the hearing examiner’s decision. The stipulated value would be used for the refund claim only if the trial court first determined revaluation was required by the hearing examiner’s decision. Instead, the trial court determined that revaluation was not required by the hearing examiner’s decision, and we agree. As a result, the oral stipulation has no bearing on this appeal.
[¶ 13.] The written Stipulation and Agreements as to the property value in the two companion cases likewise have no bearing on the refund claim before us. These later Stipulation and Agreements pertained only to the two appeals brought before the trial court and did not pertain to the refund claim. They are not part of the trial court’s record of the refund claim and cannot properly be considered on appeal.
[¶ 14.] The trial court’s decision dismissing the Petitioners’ action for refund of real estate taxes is affirmed.
[¶ 15.] GILBERTSON, Chief Justice, and KONENKAMP and ZINTER, Justices, concur. [¶ 16.] SABERS, Justice, dissents.. SDCL 10-12-42 varies the maximum annual tax levy that may be imposed based upon the classification of the property.
. SDCL 10-27-2 provides the basis for the claim.
. The effect of a pre-evidence stipulation and the later Stipulation and Agreements are discussed at length in the briefs of the parties. However, due to this Court's resolution of the first issue, the stipulations have no bearing on this appeal.
. The hearing examiner’s decision was made on August 16, 1999. Effective November 1, 2000, SDCL 10-3-16 was amended to state: "No legal presumption of correctness attaches to the director’s assessed valuation of property.”
