OPINION
This сase presents for review the decision of the Court of Appeals which reversed the Chancery Court’s dismissal of the petition of Schering-Plough Healthcare Products, Inc. (“Schering-Plough”) which sought judicial review of a decision of the State Board of Equalizаtion (“Board”). The Chancery Court dismissed the petition after concluding that it lacked subject matter jurisdiction over the action because Schering-Plough had failed to name Shelby County as a party in the petition and had failed to serve Shelby County with a copy of the petition within sixty days of the final decision of the Board. The Court of Appeals reversed the dismissal and held that Tenn.Code Ann. § 4-5-322(b) (1998 Repl.) does not require that all parties to the contested case be named in the petition for review or that copies of the petition be served upon all parties to the contested case within the sixty-day time limitation. We agree and now affirm the decision of the Court of Appeals.
BACKGROUND
The facts relevant to the legal question in this appeal are undisputed. 1 Schering-Plough owns property located in Shelby County. The Shelby County Board of Equalization prepared a tax assessment of the property. On September 1, 1994, *775 Schering-Plough appealed the assessment. On October 18, 1994, following a hearing, the administrative law judge issued an initial decision and order affirming the assessment. See TenmCode Ann. § 67-5-1505 (1998 Repl.). Schering-Plough appealed this decision to the Assessment Appeals Commission (“Commission”), which issued its final decision affirming the assessment on April 10, 1995. See Tenn. Code Ann. § 67-5-1506 (1998 Repl.). The Board declined to review thе Commission’s decision on May 25, 1995 and thereby rendered the action of the Commission final. See TenmCode Ann. § 67 — 5—1502(j)(l) (1998 Repl.). It is undisputed that Shelby County through its Assessor’s office participated as a party in the contested case before the administrative law judge and the Commission.
On July 21, 1995, within sixty days of the agency’s final decision, Schering-Plough filed in the Shelby County Chancery Court a “Petition for Review of the Action of the State Board of Equalization.” On September 25, 1995, the Board moved to dismiss the action because Schering-Plough had not named Shelby County as a party in the petition and because Scher-ing-Plough had not served a copy of the petition upon Shelby County within sixty days of the agency’s final order.
Two days later, on September 27, 1995, Schering-Plough moved to amend its petition to add as party defendants Shelby County, the Shelby County Assessor, and the Shelby County Trustee. After these motions were filed, Schering-Plough served a copy of the petition upon these additional parties. Thereafter, Shelby County, the Assessor, and the Trustee filed a joint motion to quash service, or in the alternative, to dismiss, relying upon the same grounds alleged by the Board: failure to name all parties to the contested case and failure to serve a copy of the petition upon all parties to the contested case within sixty days of the final order of the agency.
Following a hearing, the Chancellor granted the Board’s motion to dismiss, stating “Schering-Plough’s failure to name Shelby County as a defendant and to serve upon the County ... a copy of the Petition renders this Court without subject matter jurisdiction over this action.”

Thе Court of Appeals reversed the dismissal and held that Schering-Plough had properly preserved its right to judicial review of the administrative decision simply by filing its petition for review with the Chancery Court within sixty days of the final agency decision. Relying upon this Court’s decision in Jaсo
v. Department of Health, Bureau of Medicaid,
STATUTORY CONSTRUCTION
In resolving the issues in this appeal, we are guided by the following general rules of statutory construction. The role of this Court in construing statutes is to ascertain and give effect to legislative intent.
Cronin v. Howe,
With these principles in mind, we next consider the statute that is the focus of this appeal. Under the Uniform Administrative Procedures Act (UAPA), 3 a party aggrieved by a final decision of an administrative agency may seek judicial review of the contested case. Tenn. Code Ann. § 4r- 5-322(a) (1998 Repl.). The procedure fоr obtaining review is delineated in Tenn. Code Ann. § 4-5-322(b) (1998 Repl.), which provides, in pertinent part:
(1) Proceedings for review are instituted by filing a petition for review in the chancery court of Davidson County, unless another court is specified by statute. 4 Such petition shall be filed within sixty (60) days after the entry of the agency’s final order thereon. ...
(2) In a case in which a petition for judicial review is submitted within the sixty-day period but is filed with an inappropriate court, the case shall be transferred to the appropriate court.... Copies оf the petition shall be served upon the agency and all parties of record, including the attorney general and reporter, in accordance with the provisions of the Tennessee Rules of Civil Procedure pertaining to service of process.
(Emphasis added.) We agree with the Court of Appeals that the plain language of this statute imposes only two requirements upon a party seeking judicial review of a contested case. First, the statute requires an aggrieved party to file a pеtition for review in an appropriate chancery court within sixty days after entry of the agency’s final order. The sixty-day time limitation upon filing of the petition is jurisdictional.
Bishop v. Department of Correction,
Contrary to the Board’s assertions, these are the only two procedural requirements under Section 322 for obtaining judicial review of a contested case.

Nothing in the statute mandates that the petition itself name all the parties to the contested case. So long as a copy of the petition is served upon the “parties of record” to the contested case, the unambiguous dictates of the statute are satisfied. Though we base our decision on the plain language of the statute, we agree with the Court of Appeals that a petition for review is comparable to a notice of appeal. As we stated in
Jaco,
a petition for judicial review is the continuation of an administrative proceeding in much the same way that an aрpeal can be characterized as a continuation of the underlying action. The parties to the contested case have previously
*777
been determined and are “of record.”
Jaco,
Moreover, we reject the Board’s argument that dismissal is required unless a copy of the petition for review is served within sixty days after entry of the final agency order. While the statute clearly requires that the petition for review be
filed
within the sixty-day time period, the statute does not mandate that
service
occur within that same time period. The sixty-day limitation appears in the statutory subsection relating to
filing
not
service
of the petition for review. In fact, the statute does not designate a definite time period within which service must be accomplished. It provides only that service of a copy of the petition be accomplished in accordance with the Tennessee Rules of Civil Procedure pertaining to service of process. As we stated in
Jaco,
this portion of the statute refers only to the method and means of service set forth in the mies.
Jaco,
The Board’s assertions that an aggrieved party must name all the parties to the contested case in the petition for review and serve the petition for review within the sixty-day time period simply are not supported by the plain language of the statute. As previously stated, where the language contained within the four corners of a statute is plain, clear, and unambiguous, courts аre not at liberty to depart from the language of the statute. Judicial construction simply is not appropriate.
Carson Creek Vacation Resorts, Inc.,
For the reasons discussed above, we reject the Board’s proposed construction of Tenn.Code Ann. § 4-5-322(b) (1998 Repl.). The plain language of the statute does not require an aggrieved party to name all parties of record to the contested case in the petition for judicial review, nor does it require service of a copy of the petition within the sixty-day time period. 6 Thе plain language of the statute requires only that a petition for review be filed within sixty days after entry of the final agency order and that a copy of the petition be served upon the agency and all parties of record, including the Attorney General and Reporter, in accordance with the method and manner prescribed by the Tennessee Rules of Civil Procedure for service of process.
CONCLUSION
Applying these principles to the facts of this case, it is clear that Schering-Plough *778 has satisfied both statutory requisites. Schering-Plough’s petition for review was filed within the sixty-day time limitation. The parties of record to the contested case have been served with a copy of the petition. Accordingly, the decision of the Court of Appeals reversing the Chаncery Court’s dismissal is affirmed.
Notes
. We do not include a summary of the facts relating to the assessment of Schering-Plough’s property since the appropriateness of the assessment is not an issue in this appeal.
. At the trial level, the Board alleged and the Chanсellor cited a third basis in support of dismissal — failure to serve process on all parties of record. In light of this Court’s decision in
Jaco
v.
Department of Health, Bureau of Medicaid,
. Tenn.Code Ann. §§ 4-5-101 through 4-5-325 (1998 Repl.).
. At the time of the filing of Schering-Plough's petition for review on July 21, 1995, Tenn.Code Ann. § 67-5-1511 (1994 Repl.) permitted the filing of a petition for review of a decision of the Board in "Davidson County or the chancery court of the county where the disputed assessment was made.” In this case, the disputed assessment was in Shelby County, and Schering-Plough filed its petition in thе Shelby County Chancery Court.
.The Board’s reliance upon Tenn.Code Ann. 67-5-1511(b) (1998 Repl.) is misplaced. This statute governs the scope of evidence admissible at a chancery court hearing on a petition for judicial review of a decision of the Board. It does nоt delineate the procedure required for obtaining judicial review in chancery court in the first instance.
. To the extent inconsistent with our decision herein all previous appellate court decisions are overruled including
HRA, Inc. v. Department of Commerce & Ins.,
