Petitioner assigns error in the denial of the motion to amend his pleading to include a further section alleging failure on the part of the Town to meet the prerequisites to annexation set forth in G.S. 160A-47(3) by not indicating in the annexation report the plans of the Town to extend bus service into the annexed area which petitioner contends is a major service provided by the Town. This argument is without merit.
The motion to amend was addressed to the sound discretion of the court. The denial of such motion is reviewable only for manifest abuse of discretion. Vending Co. v. Turner, 267 N.C. 576, 148 S.E. 2d 531 (1966); Crump v. Eckerd’s Inc., 241 N.C. 489, 85 S.E. 2d 607 (1955); see also G.S. 1A-1, Rule 15. The record indicates petitioner first moved to amend orally in open court at the 18 February 1980 hearing. A written version of the amendment was filed on 6 March 1980. The trial court denied the motion at the 18 February hearing. This denial was not an abuse of discretion. The judicial review afforded in annexation proceedings is limited in scope. The review is afforded pursuant to G.S. 160A-50 and serves as a safeguard against unreasonable and arbitrary action by the annexing municipality. See G.S. 160A-50(f). The clear intent of the legislature is that this review be expedited. The petition for review must be filed within thirty days following passage of the annexation ordinance. G.S. 160A-50(a). “Such petition shall explicitly state what exceptions are taken to the action of the governing board and what relief the petitioner seeks.” G.S. 160A-50(b) (emphasis added). The petition must be served on the town within five days of its filing and the town then has fifteen days or such additional time as the court may allow to provide the court with a transcript of the minutes relating to the annexation and a copy of the annexation report. G.S. 160A-50(b)(c). The court must then set a hearing date, preferably within thirty days following the last day for *323receiving petitions “to the end that review shall be expeditious and without unnecessary delays.” G.S. 160A-50(f). The statute requires that petitioner “explicitly state what exceptions are taken,” and he did not do this with respect to bus service. Nor did he attempt to explain his failure to raise the question of bus service in the petition he initially filed. To allow the amendment on the day of the hearing would ordinarily cause needless delay. The record indicates that bus service within the Town of Carr-boro is provided by the Town of Chapel Hill according to contractual arrangement between the two towns. The routing of the bus service was the responsibility of the Town of Chapel Hill, and the Carrboro town manager termed routing “a political question.” If bus service is a proper issue for the reviewing court to consider as one of the prerequisites to annexation, some evidence from the Town of Chapel Hill seemingly would be required. To allowthis attackthrough amendment on the day of the hearing would constitute unnecessary delay in an expedited hearing procedure. The superior court did not abuse its discretion in denying the motion to amend.
We do not reach the question whether bus service is indeed a “major municipal service performed in the municipality at the time of annexation” within the contemplation of G.S. 160A-47(3) which would require that the plan of annexation state how such service would be extended into the annexed area. Nor do we reach the question whether a “major municipal service” which is not specifically listed in G.S. 160A-47(3) a, b, c, such as bus service, should be discussed in the annexation report.
 Review of an annexation ordinance is provided in the superior court of the county in which the municipality is located and “shall be conducted by the court without a jury.” G.S. 160A-50(f). Petitioner argues that the entire procedure for annexation by cities of 5,000 or more, G.S. 160A-45 to -56, is unconstitutional in that it does not provide for trial by jury on issues of fact as required by N.C. Const, art. I, § 25 for “controversies at law respecting property.” This argument has been raised before and squarely rejected. In re Annexation Ordinance, 284 N.C. 442, 202 S.E. 2d 143 (1974); In re Annexation Ordinance, 253 N.C. 637, 117 S.E. 2d 795 (1961). In the 1961 case, this Court said:
*324The procedure and requirements contained in the [annexation legislation] being solely a legislative matter, the right of trial by jury is not guaranteed, and the fact that the General Assembly did not see fit to provide for trial by jury in cases arising under the Act, does not render the Act unconstitutional.
The right to a trial by jury, guaranteed under our Constitution, applies only to cases in which the prerogative existed at common law, or was procured by statute at the time the Constitution was adopted. The right to trial by jury is not guaranteed in those cases where the right and remedy have been created by statute since the adoption of the Constitution.
 Petitioner further attacks the constitutionality of the annexation procedure on the ground that it authorizes a taking of private property without just compensation in violation of the due process clause of the Fifth Amendment of the United States Constitution and the law of the land provision found in the North Carolina Constitution, art. I, § 19. Petitioner’s basic argument is that he will pay a substantial sum in ad valorem taxes to the Town without receiving any substantial benefits or major services he does not already receive. A similar constitutional claim was rejected in In re Annexation Ordinance, 253 N.C. 637, 117 S.E. 2d 795 (1965), where the Court stated:
Certainly it would seem that [petitioners] do not desire to have their respective properties subject to the levy of city taxes. Even so, where additional territory is annexed in accordance with the law, the fact that the property of the residents in such area will thereby become subject to city taxes levied in the future, does not constitute a violation of the due process clause of the State and Federal Constitutions.
253 N.C. at 651-52, 117 S.E. 2d at 805. Petitioner has adequate due process safeguards within the existing annexation law to assure that he gets Town services on a nondiscriminatory basis. However, “there is no requirement that a municipality duplicate services, in an area to be annexed, which are already *325available in the area.” Huntley v. Potter, 255 N.C. 619, 632, 122 S.E. 2d 681, 689 (1961); see also In re Annexation Ordinance, 296 N.C. 1, 249 S.E. 2d 698 (1978). Thus the Town need not lay a sewer or water line where it does not do so for anyone else and where service is provided by an independent authority. The Town has submitted a plan pursuant to G.S. 160A-47 demonstrating it will provide its services equally. But, if petitioner discovers he is not receiving services other residents are receiving, whatever those services may be, within twelve to fifteen months from the effective date of the annexation, he may petition for a writ of mandamus pursuant to G.S. 160A-49(h). The annexation procedure adequately provides protection to the annexed area to assure that its citizens get adequate nondis-,eriminatory municipal services.
Petitioner next argues that the superior court erred in fii .ding as fact that the Revised Annexation Plan Report of the Town complied with the annexation statutes in that it failed to comply with the declarations of State policy found in G.S. 160A-45 and failed to comply with several of the prerequisites to a valid annexation found in G.S. 160A-47. There is no merit in any of these contentions.
 Petitioner contends the Revised Annexation Plan Report does not state any policy objectives to be met by the annexation of his property. The report states: “The North Carolina General Assembly recognizes the extension of municipal boundaries through annexation as a desirable mechanism to promote sound urban development and assure adequate provision of government services” and then quotes the body of G.S. 160A-45 which provides:
(1) That sound urban development is essential to the continued economic development of North Carolina;
(2) That municipalities are created to provide the governmental services essential for sound urban development and for the protection of health, safety and welfare in areas being intensively used for residential, commercial, industrial, institutional and governmental purposes or in areas undergoing such development;
*326(3) That municipal boundaries should be extended in accordance with legislative standards applicable throughout the State, to include such areas and to provide the high quality of governmental services needed therein for the public health, safety and welfare;
(4) That new urban development in and around municipalities having a population of 5,000 or more persons is more scattered than in and around smaller municipalities, and that such larger municipalities have greater difficulty in expanding municipal utility systems and other service facilities to serve such scattered development, so that the legislative standards governing annexation by larger municipalities must take these facts into account if the objectives set forth in this section are to be attained;
(5) That areas annexed to municipalities in accordance with such uniform legislative standards should receive the services provided by the annexing municipality as soon as possible following annexation.
G.S. 160A-45. Petitioner argues this is insufficient compliance with State policy outlined in G.S. 160A-45 in view of his position that (1) the Town has neither the ability nor the intention to provide the promised services, (2) petitioner neither needs nor wants the services and (3) petitioner’s land is not ripe for annexation in the opinion of a majority of the Carrboro Planning Board.
The grounds asserted for invalidity of the annexation are not properly raised under G.S. 160A-45. Rather, they are merely arguments addressed to the mechanics of annexation dealt with in G.S. 160A-46 to -49. For example, the question whether the area is ripe for annexation should be addressed under the statutory criteria set up in G.S. 160A-48. See, e.g., Food Town Stores v. Salisbury, 300 N.C. 21, 265 S.E. 2d 123 (1980). Petitioner has made no such argument. The Town states that the annexation is designed to promote sound urban development and assure adequate provision of government services. That is a *327sufficient compliance with the general statement of legislative intent found in G.S. 160A-45. If petitioner seeks to invalidate the annexation, he must show noncompliance with the requirements for annexation found in G.S. 160A-46 to -49. Petitioner has made some arguments to that effect which we discuss next.
The annexation plan submitted by a municipality must show prima facie complete and substantial compliance with the annexation statutes as a condition precedent to the right to annex. In re Annexation Ordinance, 296 N.C. 1, 249 S.E. 2d 698 (1978); Huntley v. Potter, supra. “[Sjlight irregularities will not invalidate annexation proceedings if there has been substantial compliance with all essential provisions of the law.” In re Annexation Ordinance, 278 N.C. 641, 648, 180 S.E. 2d 851, 856 (1971).
Petitioner has attacked the adequacy of the annexation report under standards provided in G.S. 160A-47. The superior court at the 18 February hearing properly remanded the original Annexation Plan Report to the Town Board for amendment of the plans for providing services to the end that the provisions of G.S. 160A-47 be satisfied. See G.S. 160A-50(g)(3). The amended report was approved by the superior court at the 4 March hearing. It is that amended report which petitioner contends is flawed.
 Petitioner contends maps prepared by the Town as part of the Revised Annexation Plan Report do not comply with the requirements of G.S. 160A-47(1), which provides that the report shall include:
A map or maps of the municipality and adj acent territory to show the following information:
a. The present and proposed boundaries of the municipality.
b. The present major trunk water mains and sewer interceptors and outfalls, and the proposed extensions of such mains and outfalls as required in subdivision (3) of this section.
c. The general land use pattern in the area to be annexed.
*328He contends the maps were inadequate because they failed to include the entire boundary of the Town and contained blank areas.
The eastern boundary and approximately one-fifth of the Town area was omitted. The entire area to the north and west of the Town contiguous to the area to be annexed and that area itself was included on the maps. The map showing the general land use pattern contains several blank areas. The blank areas apparently represent vacant lots which do not appear as a category on the legend of the maps. The maps are in substantial compliance with G.S. 160A-47(1).
 Petitioner complains that the Revised Annexation Plan Report is not sufficiently specific with respect to providing police and garbage collection services as required by G.S. 160A-47(3)a. The plan statements on these services are quite adequate. Similar statements have been approved. See In re Annexation Ordinance, 255 N.C. 633, 122 S.E. 2d 690 (1961).
Petitioner also contends the plan is insufficient with respect to extension of street maintenance service as required by G.S. 160A-47(3)a. The plan details what services are provided in the Town and states that all such services will be provided in the annexed area. Providing a nondiscriminating level of services within the statutory time is all that is required.
Petitioner’s final attack on the Revised Annexation Plan Report deals with the failure of the Town to provide for extension of water and sewer lines. As heretofore pointed out, this is not a service provided by the Town to anyone. It is a duty vested with OWASA, an independent water authority. See G.S. 162A-1, et seq.
In summation, the Revised Annexation Plan Report is in substantial compliance with statutory requirements. The annexation ordinance cannot be voided on any ground raised in these arguments concerning the report on the plan to extend services to the annexed area.
 The final question we must address on this appeal is the effective date of the annexation ordinance. The ordinance was adopted on 19 December 1979 to become effective 31 December 1979. This proceeding for review of the annexation was instituted on 18 January 1980 within thirty days from the passage of *329the ordinance as required by G.S. 160A-50(a). At the 18 February hearing, the superior court remanded the Annexation Plan Report to the Town Board of Aldermen for a more specific statement of the services to be provided and the sources of revenues to finance such services. A revised plan was adopted by the Board of Aldermen on 26 February 1980, and this report was approved by the superior court at the 4 March 1980 hearing. The judgment and order provided that the annexation ordinance adopted 19 December 1980 was effective and enforceable. The judgment and order did not specify the effective date of the ordinance. The facts of this case present a conflict between G.S. 160A-50(a) and (i). The provisions in question read as follows:
Within 30 days following the passage of an annexation ordinance under authority of this Part, any person owning property in the annexed territory who shall believe that he will suffer material injury by reason of the failure of the municipal governing board to comply with the procedure set forth in this Part or to meet the requirements set forth in G.S. 160A-48 as they apply to his property may file a petition in the superior court of the county in which the municipality is located seeking review of the action of the governing board.
G.S. 160A-50(a) (emphasis added).
If part or all of the area annexed under the terms of an annexation ordinance is the subject of an appeal to the superior or Supreme Court on the effective date of the ordinance, then the ordinance shall be deemed amended to make the effective date with respect to such area the date of the final judgment of the superior or Supreme Court, whichever is appropriate, or the date the municipal governing board completes action to make the ordinance conform to the court’s instructions in the event of remand.
G.S. 160A-50(i) (emphasis added). Petitioner appealed to the superior court within the time limits of G.S. 160A-50(a) but not before the effective date of the ordinance.
Substantial compliance with the annexation statute is a condition precedent to effective annexation. In re Annexation *330 Ordinance, 296 N.C. 1, 249 S.E. 2d 698 (1978); In re Annexation Ordinance, 255 N.C. 633, 122 S.E. 2d 690 (1961). At the 18 February hearing, the superior court found the procedure not to be in substantial compliance due to failure to be specific in the Annexation Plan Report with respect to the services provided and their financing as required in G.S. 160A-47(3) and remanded the Annexation Plan Report for amendment by the Town Board pursuant to G.S. 160A-50(g)(3). Thus the ordinance could not be effective 31 December 1979 due to the infirmities. Since the infirmities were cured by the revised plan adopted on 26 February 1980, this date became the effective date of the annexation ordinance subject to further appeal to the superior court. Such appeal was taken. The superior court entered an order on 4 March 1980 approving the 26 February 1980 Revised Annexation Plan Report and affirming the annexation. The effective date of the annexation thus became 4 March 1980 subject to further appeal to the Supreme Court. Since plaintiff petitioner appealed from that judgment to the Supreme Court, the effective date of the ordinance was again postponed by the language of G.S. 160A-50(i) until the date of the final judgment of the Supreme Court.
The foregoing interpretation of the statutes correctly resolves the conflict between G.S. 160A-50(a) and (i). It was not the legislative intent to authorize the municipality to shorten the thirty-day period allowed aggrieved property owners within which to file a petition in the superior court for review of the annexation proceeding. To hold otherwise would produce an absurd and unjust result. For example, in this case, plaintiff petitioner would have had only eleven days during the Christmas holidays in which to seek review of the proceeding.
We hold that the effective date of the annexation order here in question will be the date on which the final judgment of this Court is certified to the Clerk of the Superior Court of Orange County.
For the reasons stated, the judgment of the superior court upholding the annexation is
Justice Brock took no part in the consideration or decision of this case.
