Antelope Valley Improvement and Service District of Gillette (Antelope Valley) applied to the Department of Revenue (Department) for a sales and use tax exemption in 1997. The Department denied the application by final deсision letter dated October 15, 1997, and Antelope Valley filed its appeal November 17, 1997. The Board of Equalization (Board) dismissed the appeal as untimely filed, and Antelope Valley appealed to the district court, which affirmed the decision of the Board.
In its appeal before this Court, Antelope Valley argues the Board’s rule concerning filing of appeals violates due process because it does not require actual notice before the time for appeal begins to run. Antelope Valley also contends the Board’s decision was not supported by substantial evidence. The Board applied its properly promulgated rules, which have the force and effect of law, and its decision is supported by substantial evidence. There is no evidence in the record that Antelope Valley did not have an opportunity to respond and be heard. Absent that evidence, due process is not implicated. Therefore, we affirm the decisions of the district court and the Board.
ISSUES
Antelope Valley presents this statement of the issues for review:
I. Did the Board of Equalization have sufficient evidence upon which to base its decision?
II. Did the district court improperly affirm the Board of Equalization’s dismissal of the appeal of Antelope Valley?
The Department of Revenue presents these issues:
I. Whether the Wyoming State Board of Equalization acted in accordance with law when it dismissed the appeal of Antelope Valley with prejudice for lack of subject matter jurisdiction.
II. Whether the Wyoming State Board of Equalization acted contrary to constitu: tional rightwhen it dismissed the appeal of Antelope Valley with prejudice for lack of subject matter jurisdiction.
FACTS
By letter dated October 15, 1997, the Department denied a request by Antelope Valley for a sales and use tax exemption. The letter notified Antelope Valley that it was a final administrative decision subject to appeal to the Board “within thirty (30) days of this notice date.” Antelope Valley filed a case notice of appeal with thе Board on November 17, 1997. After reviewing the notice, the Board issued a notice of its intent to dismiss the appeal with prejudice because the appeal was untimely filed. After accepting briefs from both parties and affidavits-from Department emрloyees on the timeliness issue, the Board issued its decision that it was without jurisdiction to hear the appeal because the notice of appeal was untimely filed.
Antelope Valley timely filed a petition for review of the order of dismissal with the distriсt court, and the district court affirmed the Board’s order. Antelope Valley now appeals to this Court seeking review of the order of dismissal.

' In reviewing an administrative agency decision on appeal, this Court shall hold unlawful and set aside agency aсtion found to be: (1) arbitrary, capricious, an abuse of discretion or otherwise not in accordance with law; (2) contrary to constitutional right, power, privilege dr immunity; (3) without observance of procedure required by law; or (4) unsupported by substantial evidеnce. Wyo. Stat. Ann. § 16-3-114(c)(ii)(A), (B), (D) and (E) (LEXIS 1999). Antelope Valley contends the Board’s decision was not supported by substantial evidence. Substantial evi

The Board’s Rule
Chaptеr 2, Section 5 (Section 5) of the Rules and Regulations of the Wyoming State Board of Equalization (1995) (Board Rule) establishes the time period for filing an appeal with the Board from a final administrative decision of the Department. Section 5 provides:
(a) Cases may be instituted by any petitioner who files a case notice for review of any final administrative decision of the Department with the Board c/o executive secretary. ... Unless otherwise required by law, the case notice shall be filed with the Board within thirty (30) days of the date of the final administrative decision at issue.
(b) “Computation of Time” — In computing the time period for filing a case notice, the period shall begin on the day after the date of the final administrative decision and shall conclude on the last day of such computed period, unless such day is a Saturday, Sunday or legal holiday, in which event the period runs until the end of the next day which is neither a Saturday, Sunday nor a legal holiday.
(c)“Filed with the Board” — The case shall be considered filed with the Board upоn mailing of the case notice as evidenced by a postmark, or upon receipt by fax. Any case notice not timely filed shall be dismissed.
Subsection (c) of the Board Rule requires the Board to dismiss “any case notice not timely filed,” and the Board applied the rule when it determined it did not have jurisdiction to hear Antelope Valley’s appeal. Rules adopted pursuant to statutory authority and properly promulgated have the force and effect of law.
Fullmer v. Employment Security Comm’n,
Rules of statutory interpretation apply to the interpretation of administrative rules and regulations.
Glover v. State,
The unambiguous language of Section 5 dictates that the time period for filing a case notice of appeal begins to run on the day after the date of the decision and ends thirty days later. Antelope Valley contends the Department did not provide evidence that it mailed the decision letter on the date of the *567 letter. However, the Board Rule does not contemplate use of the date the letter was mailed. Rather, the only relevant date under the rule is the date of the final administrative decision.
The Department denied Antelope Valley’s exemption request by letter dated October 15, 1997. The time period for filing the appeal of that decision began to run on Thursday, October 16, 1997, and ended on Friday, November 14, 1997. The case notice of appeal was post marked November 17, 1997. Therefore, Antelope Valley did not file its case notice within the time period requirеd by the Board’s Rule. Timely filing of a request for administrative review of an agency decision is mandatory and jurisdictional.
Fullmer,
Due Process
Antelope Valley argues that it was denied due process because it did not have the benefit of the full thirty days provided for in the rule to respond. Howеver, nothing in the unambiguous language of Section 5 provides for the running of the appeal period from the date of mailing or the date of receipt of notice as opposed to the date on which the Department rendered its decisiоn. A rule that provides thirty days after the date of the decision to file an appeal does not entitle the recipient to file the appeal thirty days after actual notice of the decision.
As long as a party is afforded a reasonаble opportunity to respond to a ruling and to appeal, due process is not violated.
Jones v. Jones,
Proper Parties to Appeal
The Wyoming State Board of Equalization filed a brief with this Court as an appellee in this matter. We find no authority for an adjudicatory body to file briefs as if it were a party to the aсtion. “Generally a court or board exercising judicial or quasi judicial functions, not being a party to its proceedings, and not having any legal interest in maintaining its determination, can neither appeal from a judgment or order of a court reversing the proceedings nor be heard on the appeal.” 4 C.J.S. Appeal and Error § 175 (1993).

at 848. Similarly, the Board of Equalization lacks standing to submit an appellate brief with this Court. The appeal from a board decision ‘“is merely a сontinuation of those proceedings [board’s] in an appellate tribunal.’”
Anita Ditch Co. v. Turner,
CONCLUSION
The Board of Equalization properly found it lacked subject matter jurisdiction over this case because the appeal was not timely filed in accordance with the Board’s Rule. Antelope Valley does not contend it did not have a reasonable opportunity to respond to the decision of the Department of Revenue; therefore, due process concerns were not implicated. Finally, the Board of Equalization was the adjudicatory authority below and is not a proper party to an appeal from its own decision.
Notes
. On July 12, 1999, this section was amended, adding "or upon the date of mailing of the final administrative decision as evidenced by a postmark, whichever is later.” Board Rules, Ch. 2, § 5 (1999). However, we apply the rules in effect at the time of the appeal at issue.
