One year after Swafford’s appointment as a member and chairman of the Dade County Board of Tax Assessors, the Dade County Board of Commissioners suspended him pending removal from office, then removed him for cause pursuant to OCGA § 48-5-295. A first removal resolution was withdrawn by consent because of defective notice, but after a second hearing, Swafford was removed. He contested the removal before the Board and appealed its decision to superior court, where it was affirmed. In granting his discretionary application for review of the superior court’s order, this Court posed two questions: 1) Was the compliance with the discretionary appeal procedures necessary? See Parsons v. Chatham County Bd. of Commrs., 204 Ga. App. 130 (1) (418 SE2d 459) (1992); 2) Did the superior court *647err in affirming the decision of the Board of Commissioners?
1. Since it is incumbent on this Court to examine its own jurisdiction (Collins v. AT & T, 265 Ga. 37 (456 SE2d 50) (1995)), we address first the question of the route by which such appeals as this must come to this Court. In Parsons, supra, the Court of Appeals relied on this Court’s decision in Geron v. Calibre Cos., 250 Ga. 213 (1) (296 SE2d 602) (1982), for the proposition that judgments of trial courts reviewing decisions of a county board of commissioners may be appealed directly rather than by discretionary appeal. In Geron, this Court relied on Kirton v. Biggers, 135 Ga. App. 416 (3) (218 SE2d 113) (1975), for the proposition that a county board of commissioners is not an administrative agency. However, the final holding in that case was that “the scope and criteria of judicial review of such body’s decisions is closely analogous to that of an ‘agency.’ ” Id. at 419. While it is true that county boards of commissioners also function as legislative bodies, the function involved here, determining whether to remove from office a person appointed to that office by the board of commissioners, is the equivalent of the function of an administrative agency. That being so, we hold that appeals in cases such as this one require compliance with discretionary appeal procedures. OCGA § 5-6-35 (a) (1). To the extent they hold otherwise, Geron and Parsons are overruled.
2. Acknowledging that this Court has upheld OCGA § 48-5-295 against a due process challenge (Kirton v. Biggers, 232 Ga. 223 (1) (206 SE2d 33) (1974)), Swafford argues that the earlier case did not involve the issue he raises, which is whether he was denied due process because the body which brought his fitness for office into question was also the body which would decide that question. That, and his associated arguments that due process required that he be given a jury trial, and that the members of the Board of Commissioners were required to disqualify themselves because they had supposedly prejudged him, were sufficiently answered in Hill v. Johnson, 214 Ga. 417, 420 (105 SE2d 309) (1958):
Whether or not the members of the board of aldermen have prejudged the petitioner’s case, the legislature has designated such members as the proper forum for hearing the impeachment proceedings, and he is not denied due process of law by reason of the fact that the impeachment proceedings will be conducted by them.
3. Without citation of authority, Swafford asserts that the superior court’s review on the record rather than de novo denies him due process. We disagree. “The fundamental idea of due process is notice and an opportunity to be heard. [Cit.] Due process neither guarantees *648a right to appeal nor a particular form or method of state procedure. [Cit.]” Nix v. Long Mt. Resources, 262 Ga. 506 (3) (422 SE2d 195) (1992). The provision for the superior court to review the decision of the board of commissioners on the record is consistent with the nature of that body and its powers:
The board of commissioners, as the appointing authority of the board of tax assessors, necessarily has a certain discretion as to the level of performance which it is willing to tolerate. As long as no abuse of such discretion is shown, this court should not substitute its findings of fact or construction of the evidence for that of the governmental body having appointing and removal powers.
Kirton v. Biggers, 135 Ga. App. 416 (3), supra. We hold, therefore, that the provision for review in the superior court on the record made before the Board of Commissioners is adequate to ensure due process.
4. Swafford’s complaints about the partiality of the members of the Board of Commissioners and the county attorney, who acted as prosecutor, were waived by his failure to present them to the Board. “ ‘Generally, questions or objections which were not raised or urged in the original proceedings for review of a decision or order of a zoning official or board will not be considered on further review.’ [Cit.]” Hyman v. Pruitt, 226 Ga. 625 (1) (176 SE2d 707) (1970).
5. Swafford contends here as he did in superior court that the notice he received was inadequate to inform him of the nature of the charges he faced. “Mere vagaries or generalities are insufficient, and the notice must be ‘sufficiently specific and detailed to convey to the employee the substantial nature of the charge without requiring speculation on his part as to the precise complaint he must answer.’ ” Hughes v. Russell, 148 Ga. App. 143, 144 (251 SE2d 70) (1978). Applying that standard to the record of this case, we conclude that the notice was sufficient: as to each ground for removal, the notice provided to Swafford sufficient detail to identify the incident and persons involved and the wrongdoing alleged, including in several instances the statements of the persons involved.
6. Finally, Swafford asserts that the evidence presented to the Board of Commissioners was insufficient to warrant his removal. In considering this issue, we have reviewed the evidence presented to the board because “on appeal our duty is not to review whether the record supports the superior court’s decision but whether the record supports the initial decision of the local governing body or administrative agency .... [Cits.]” Emory Univ. v. Levitas, 260 Ga. 894, 898 (401 SE2d 691) (1991). The record in this case is replete with evidence of Swafford’s misconduct in office. Specifically, the record contains evi*649dence to support the following conclusions: that Swafford attempted to conduct certain Board of Tax Assessors business by a telephone poll rather than an openly conducted meeting; that he harassed a female tax assessor because he believes women should not be tax assessors and he wanted a man in her job; that he harassed taxpayers in an open meeting out of personal spite concerning an assessment of his property by a former employee; and that he behaved in a harassing manner to an employee during Board meetings and threatened to have her arrested for misconduct which was attributable to him, not her. We conclude that the evidence supported the Board’s removal of Swafford.
Judgment affirmed.
