The controlling question in these two companion cases which, though not consolidated, were argued together and submitted for decision upon the record and the briefs and the oral arguments of counsel, relates to the constitutionality of a statute which authorizes the creation by the County Court of Greenbrier County *481of an airport authority and empowers the authority to construct, maintain and operate an airport in that county. The statute in question is Chapter 62, Acts of the Legislature, Regular Session, 1966, known as Senate Bill No. 66, and the proceedings in which its constitutional validity or invalidity must be determined are an original proceeding in mandamus, in which this Court issued a rule returnable on a former day, and a civil action, instituted in the Circuit Court of Greenbrier County on May 31,1966 and now pending in this Court upon appeal from the final judgment of the circuit court rendered July 26, 1966.
On February 21, 1967, this Court, by order, refused to grant the writ prayed for by the petitioner in the mandamus proceeding and dismissed that proceeding ; and on the same day this Court, by order, reversed the judgment of the circuit court rendered July 26, 1966 denying a motion of the plaintiff to vacate and set aside its judgment of July 9, 1966, and reversed the judgment rendered July 9, 1966 insofar as it held and declared Senate Bill No. 66, Chapter 62 Acts of the Legislature, Regular Session, 1966, to be constitutional and valid, except as to Section 14 of that Act, and reversed that judgment insofar as it denied the plaintiff the injunctive relief sought in his complaint and affirmed the judgment of July 9, 1966 insofar only as it held and declared Section 14 of the Act to be unconstitutional ; and by its order of February 21, 1967 this Court remanded the foregoing civil action to the Circuit Court of Greenbrier County with directions that it grant to the plaintiff the relief prayed for in his complaint.
This opinion, which applies to both proceedings, is now filed for the purpose of stating the reasons which caused this Court to deny the relief sought in the mandamus proceeding and to dismiss that proceeding, and to reverse, as indicated, the judgments in the civil action and to remand that action to the Circuit Court of Greenbrier County with the specified directions.
*482The statute under consideration in these proceedings, the constitutionality of which is challenged in the civil action of Benedict v. Greenbrier County Airport Authority and others here on appeal and is asserted and defended in the mandamus proceeding, contains twenty separate sections, was passed by the Legislature of "West Virginia on February 4, 1966, and has been in effect since its passage. To the extent here pertinent it provides that the County Court of Greenbrier County is authorized to create an airport authority and to provide for its membership and the purposes for which it is created; for the appointment and removal of the members of the authority; for its acquisition of real estate and personal property, and the acquisition, construction, improvement, maintenance and operation of a public airport; for the corporate existence of the authority; for the issuance of mortgage bonds, revenue bonds, other bonds, debentures, notes and securities and security for their payment; for the exercise of the power of eminent domain by the authority; for tax exemption for its property, funds and obligations; for the authority to lease the airport and for the County Court of Greenbrier County to become the lessee of such airport and pay rental for its use and operation; for contributions to the fund of the authority by the County Court of Green-brier County and other persons; for keeping the funds and accounts of the authority; for the disposition of its surplus funds; for covering its employees by Workmen’s Compensation; and for the dissolution of the authority.
Section 1 of the Act provides that the County Court of Greenbrier County is authorized to create and establish a public agency to be known as ‘ ‘ The Green-brier County Airport Authority” for the purpose mentioned in the statute.
Section 2 provides that the authority is authorized and empowered to acquire, equip, construct, improve, maintain and operate a public airport with all usual *483and convenient appurtenances and facilities in Green-brier County.
Section 3 provides that the management and control of the airport, its property, operations, business and affairs shall be lodged in a board of five persons who shall be known as “Members of the Authority” and that such members shall be appointed by the County Court of Greenbrier County; that one of such members shall be a member of the county court of that county and that of the remaining four members no more than two shall be members of the same political party.
Section 9 provides that the airport authority shall have power and authority, among others, to acquire lands and hold title to such lands in its own name; to purchase, own, hold, sell and dispose of personal property and to sell, lease or otherwise dispose of any real estate which it may own; to borrow money and execute and deliver negotiable notes, mortgage bonds, other bonds, debentures, and other evidences of indebtedness, and to give security for their payment by mortgage, deed of trust, or other security agreements with respect to its airport property and facilities in connection with the issuance of mortgage bonds, and to raise funds by the issuance and sale of revenue bonds in the manner provided by the applicable provisions of Article 4A, Chapter 8, Code, 1931, as amended.
Section 14, the validity of which is also involved in these proceedings, provides that the airport authority may lease its airport and facilities to the County Court of Greenbrier County or other available lessee at such rental and upon such terms and conditions as the authority shall deem proper but preference is given to the county court to act as such lessee; and the County Court of Greenbrier County is authorized to enter into such lease at such rental and upon such terms and conditions as it shall deem proper and to levy taxes as provided by law for the purpose of paying the rent for such airport and its facilities.
*484In tbe mandamus proceeding tbe petitioner alleges that it is presently engaged in tbe construction of tbe airport authorized by tbe foregoing statute at Max-welton, in Greenbrier County, and requires money to be raised by the sale of revenue bonds to meet tbe construction costs of tbe airport; that by proper action of its members a resolution was adopted July 21, 1966 authorizing tbe issuance and sale of $400,000.00 in airport revenue bonds and that by a subsequent resolution adopted September 13, 1966 tbe chairman and tbe secretary of tbe authority were directed to issue, under their signature and tbe seal of tbe authority, an interim certificate in tbe amount of $50,000.00 to be offered for sale to a designated bank in East Rainelle, West Virginia, whose officers bad indicated an interest in tbe purchase of such certificate; that tbe secretary of tbe authority, who has tbe mandatory and nondiscretionary statutory duty to affix tbe seal of tbe authority and to place bis signature upon tbe certificate, has refused and continues to refuse to affix tbe seal of tbe authority and place bis signature upon tbe certificate because be entertains tbe belief that tbe statute is unconstitutional, and tbe petitioner seeks a writ to require him to execute tbe certificate in tbe manner indicated and demanded by tbe petitioner.
Tbe answer of tbe defendant in tbe mandamus proceeding admits tbe allegations of tbe petition and by bis demurrer to the petition tbe defendant asserts for specified reasons that tbe statute is unconstitutional.
In bis complaint in tbe civil action, here on appeal from tbe judgment of tbe Circuit Court of Greenbrier County, the plaintiff charges that tbe defendant Green-brier County Airport Authority has designated a large part of plaintiff’s farm as tbe site or location for tbe construction of an airport and has caused surveying to be done with tbe result that it proposes to occupy for such airport about 135 acres of bis farm; that it has published in newspapers notices inviting sealed bids for labor, materials and equipment for the con-*485straction of the airport but that neither the authority nor the County Court of Greenbrier County has acquired any interest in the lands of the plaintiff but that the plaintiff is informed and believes that the authority will institute an eminent domain proceeding, authorized by the statute, to acquire title to about 135 acres of his land. The plaintiff also charges, on information and belief, that the authority proposes to issue and sell revenue bonds as authorized by the statute in the manner provided by Article 4A, Chapter 8, Code, 1931, as amended, to raise part of the funds required for the construction of the airport, in the amount of approximately $500,000.00; that the power granted the authority by the statute to lease to the county court and the county court to lease from the authority the proposed airport and its facilities upon such terms and conditions as the county court shall deem proper and to authorize the county court to levy taxes for the purpose of paying the rent for such airport and its facilities constitutes a mere plan by which the county court can undertake to purchase the airport and its facilities upon an installment basis from funds derived from taxation to pay any revenue bond indebtedness of the authority and that such authorization, without the approval of a vote of the people of Greenbrier County, as required by Article X, Section 8, of the Constitution of this State, renders the statute unconstitutional, null and void and of no effect. The plaintiff also charges that the statute is unconstitutional, null and void and of no effect because violative of the provisions of Article VI, Section 39, of the Constitution of this State, in that it is a special act which has been enacted where a general law would be proper and could be made applicable to the case; and the prayer of the plaintiff, as set forth in his complaint, is that the statute be declared to be unconstitutional in its entirety, that the County Court of Greenbrier County and its individual commissioners be enjoined from levying any tax for the purpose of paying any rentals provided by the statute under any *486lease of the airport to the county court by the Green-brier County Airport Authority, and that the authority and its individual members be enjoined from seeking to acquire any part of the lands of the plaintiff in a proceeding in eminent domain.
The answer of the defendants admits most of the material allegations of the complaint but denies that the authority intends to institute an eminent domain proceeding against the land of the plaintiff, denies that the county court intends to lease any of the facilities of the airport or to levy any tax for that purpose, and denies the allegations of the complaint to the effect that the statute or any of its provisions is unconstitutional, null and void, but avers that the statute is not a special act that violates Article VI, Section 39, of the Constitution of this State.
The material facts involved in the mandamus proceeding are not disputed and there is little, if any, dispute in the material facts involved in the civil proceeding; and the identical question presented in each proceeding, involving the constitutional validity or invalidity of the statute, is a question of law.
The petitioner in the mandamus proceeding and the defendants in the civil action assert that the statute is valid and constitutional in all respects and is not violative of Article VI, Section 39, or of Article X, Section 8, of the Constitution of this State. On the contrary the defendant in the mandamus proceeding and the plaintiff in the civil action insist that the statute in its entirety is unconstitutional as violative of Article VI, Section 39, and that Section 14 is unconstitutional as violative of Article X, Section 8, of the Constitution of this State.
Article VI, Section 39, of the Constitution of this State, which has been considered by this Court in numerous cases, provides that the Legislature shall not pass local or special laws in any of eighteen enumerated instances and that it shall provide, by general *487laws, for the previously specified special acts “and all other cases for which provision can he so made; and in no case shall a special act he passed, where a general law would he proper, and can he made applicable to the case, nor in any other case in which the courts have jurisdiction, and are competent to give the relief asked.for.”
It is conceded by the parties to each of the two proceedings that the statute here under consideration is a special act hut they differ completely as to whether the special act is violative of and is prohibited by the constitutional provision that “in no case shall a special act be passed, where a general law would be proper, and can be made applicable to the case, * * * .”
It is crystal clear, as conceded by the parties, that the statute in question is a special act and upon careful examination and consideration it is equally clear that it is a special act which has been enacted in a situation and for a purpose as to which a general law would be proper and can be made applicable. The act is limited to and deals solely with the airport in Greenbrier County but its provisions could properly be made applicable to an airport in any section of the State. There is nothing in the statute that indicates that the airport in Greenbrier County should be given authority and power that could not, with equal propriety, be given to an airport in any other of the fifty five counties of this State in which the same kind of airport could be constructed and would be desired by the people of any particular section. There appears to be no good reason why the subject of the creation, acquisition, construction, maintenance and operation of an airport and its facilities should not be authorized and dealt with by a general statute which would apply to the entire State and all of its political subdivisions. That an airport may properly be subjected to and dealt with by a general statute has been and was recognized by the Legislature of this State long prior to the enactment of the present statute. Before the *488passage of Chapter 62, Acts of the Legislature, Regular Session, 1966, a general statute relating to airports, now designated as Chapter 8, Article 11, Code, 1931, was originally enacted by the Legislature as Chapter 61, Acts of the Legislature, Regular Session, 1929, and, as amended, has been in effect since its enactment. The existence of that statute amounts to a recognition by the Legislature that airports constitute a subject which should be properly dealt with by a general law and to which a general law is clearly applicable. Brozka v. County Court of Brooke County, 111 W. Va. 191, 160 S. E. 914.
In the Brozka case this Court held in point 2 of the syllabus that “A special legislative enactment, purporting to relieve the taxpayers of a particular municipality from the payment of county road taxes on all taxable property within the municipality, is void as in contravention of section 39 of Article VI of the State Constitution which provides that ‘in no case shall a special act be passed, where a general law would be proper, and can be made applicable.’ ” When the special act, condemned in the Brozka case, was passed a general statute, which provided that the inhabitants of a municipality to construct and keep in repair the streets and highways within the municipality should not be required to pay any district road taxes, was in effect and applied to all the municipalities of the State. Under the general statute all municipalities were relieved from the payment of magisterial district road taxes but were not relieved from the payment of county road taxes which the special act was intended to accomplish for the particular municipality of Wells-burg. In discussing the purpose of the provision of the Constitution that “in no case shall a special act be passed, where a general law would be proper, and can be made applicable to the case,” this Court, in the opinion in the Brozka case, used this pertinent language :
*489“The obvious purpose of this constitutional provision is to preserve uniformity and consistency in the statutory enactments of the commonwealth. The approach to this and similar matters must be with that background. ‘If a general law exists which is applicable to a subject, the question whether such a law can be made applicable is resolved. The legislature has by the enactment of a general law practically decided the question. Hence if, while such a general law is in force, a special or local law is passed affecting the same subject and modifying the general law, the question of its validity is judicial; it will be held invalid in the case supposed, for, an applicable general law being in existence, it is no longer a question whether such a law can be made applicable; therefore the special or local law is prohibited.’ Lewis’ Sutherland Statutory Construction, Yol. 1, (2nd Ed.), page 340. * * * . To uphold enactments such as the one at bar would mean to make possible the destruction of uniformity of legislation in the state with reference to matters of general nature, and- in direct conflict with the principle of certainty and uniformity in such matters as required by the constitution. * * * . The wisdom and justice of a constitutional provision which prohibits an act such as the one in question from making a change in a particular locality from a statewide policy, is evident and forceful. * * * .”
Other decisions of this Court, holding special acts invalid and unconstitutional as violative of the foregoing constitutional provision, are State ex rel. The County Court of Cabell County v. Battle, 147 W. Va. 841, 131 S. E. 2d 730, holding invalid a provision of a general statute which excluded without any reasonable basis certain public officers who would otherwise be subject to a general law on the same matter as violative of the constitutional provision which forbids special laws where a general law is proper or can be made applicable to the subject; State ex rel. Dieringer v. Bachman, 131 W. Va. 562, 48 S. E. 2d 420, in which a special act attempted to legislate as to civil service *490members of the fire department of tbe city of "Wheeling, was declared to be unconstitutional because it was a special act which dealt with the subject as to which a general law was proper and could be made applicable; Baier v. The City of St. Albans, 128 W. Va. 630, 39 S. E. 2d 145; Truax-Traer Coal Company v. Compensation Commissioner, 123 W. Va. 621, 17 S. E. 2d 330; Groves v. County Court of Grant County, 42 W. Va. 587, 26 S. E. 460, in which a provision of a statute relating to the relocation of the county seat of Grant County was held to be unconstitutional as violative of the provisions of Article YI, Section 39, of the Constitution of this State.
The objects and purposes sought to be accomplished by the invalid statute here under consideration can be fully realized and accomplished by proper amendment to the existing general statute dealing with aviation and airports, Chapter 8, Article 11, Code, 1931, as amended.
For the reasons stated this Court holds that Chapter 62, Acts of the Legislature, Regular Session, 1966, a special act authorizing the County Court of Green-brier County to create an airport authority to construct, maintain and operate a public airport and appurtenances and facilities in that county, is unconstitutional, null and void in its entirety as violative of the provision of Article VI, Section 39, of the Constitution of West Virginia that “in no case shall a special act be passed, where a general law would be proper, and can be made applicable to the case,”.
The provision of Section 14 of the statute that the County Court of Greenbrier County may levy taxes as provided by law for the purpose of paying the rent for the airport and its facilities is also unconstitutional, null and void because violative of the provisions of Article X, Section 8, of the Constitution of West Virginia that “no debt shall be contracted under this section, unless all questions connected with the same, shall have been first submitted to a vote of the people, *491and have received three-fifths of all the votes cast for and against the same.” The provision of the statute was conceded by all parties in the civil action while pending in the Circuit Court of Greenbrier County to be unconstitutional and that court held correctly that such provision was violative of the quoted provision of the Constitution and for that reason was unconstitutional, null and void.
In holding the statute under consideration unconstitutional in its entirety as violative of the pertinent provisions of Article VI, Section 39, of the Constitution of this State, and in holding the foregoing provision of Section 14 of the statute unconstitutional as violative of the pertinent provisions of Article X, Section 8, of the Constitution of this State, this Court is aware of the well recognized principle that ‘ ‘ Every presumption is to be made in favor of the constitutionality of a statute, and it can never be declared unconstitutional except when it is clearly and plainly so. A reasonable doubt as to its unconstitutionality must be resolved in favor of the validity of the law.” 17 M. J., Statutes, Section 29; Tweel v. West Virginia Racing Commission, 138 W. Va 531, 76 S. E. 2d 874; Booten v. Pinson, 77 W. Va. 412, 89 S. E. 985, L.R.A. 1917A 1244; Groves v. County Court of Grant County, 42 W. Va. 587, 26 S. E. 460. That principle, however, is inapplicable and not here controlling for the reason that the unconstitutional statute in its entirety is clearly and plainly violative of the applicable provisions of Article VI, Section 39, of the Constitution of this State, and the provision of Section 14 of the statute is equally clearly and plainly violative of the applicable provisions of Article X, Section 8, of the Constitution of this State. Another well established principle applies in these proceedings and requires the holding that the foregoing statute is unconstitutional. That principle is that it is the duty of a court to declare a statute invalid if its unconstitutionality is clear. State ex rel. State Building Commission of West Virginia v. Bailey, 151 W. Va. _, 150 S. E. 2d 449; *492Nuckols v. Athey, 149 W. Va. 40, 138 S. E. 2d 344; Tanner v. Premier Photo Service, Inc., 147 W. Va. 37, 125 S. E. 2d 609; Appalachian Power Company v. The County Court of Mercer County, 146 W. Va. 118, 118 S. E. 2d 531; State ex rel. Winter v. Brown, 143 W. Va. 617, 103 S. E. 2d 892.
The petitioner in the mandamus proceeding and the defendants in the civil action cite and rely upon the decisions of this Court in Meisel v. Tri-State Airport Authority, 135 W. Va. 528, 64 S. E. 2d 32, in which this Court held that Chapter 142, Acts of the Legislature, Regular Session, 1949, creating the Tri-State Airport Authority, though a special act, did not violate the provisions of the Constitution of this State that “in no case shall a special law be passed, where a general law would be proper, and can be made applicable to the case,”; and Kanawha County Public Library v. The County Court of Kanawha County, 143 W. Va. 385, 102 S. E. 2d 712, in which this Court held that Chapter 178, Acts of the Legislature, Regular Session, 1957, a special act establishing the Kanawha County Public Library and requiring the County Court of Kanawha County to contribute to its support, was not invalid as in contravention of the provisions of Article VI, Section 39, or Article VIII, Section 24, of the Constitution of this State. Those cases are clearly distinguishable from the instant proceedings and do not apply to or control the decision of this Court in the proceedings here under consideration.
Special considerations existed in connection with the Tri-State Airport. It had been established by the cooperative efforts of five public bodies, the County Court of Cabell County, the County Court of Wayne County, the city of Huntington, the city of Kenova, and the town of Ceredo, each of which was a separate and distinct entity and each of which was independent of and not subject to control by any of the others. In addition a private civic organization known as the Huntington Industrial Corporation was involved in *493the undertaking and had provided or raised the fnnds required to obtain the land on which the airport was located. Federal fnnds were needed to improve the airport and it is evident that the Federal authorities required a local sponsor who was authorized to enter into agreements with the Civil Aeronautics Administation and the State Board of Aeronautics. In answering the challenge that the special act creating the Tri-State Airport Authority was violative of Article VI, Section 39, of the Constitution of this State, this Court, in the opinion, said: ‘ ‘ The answer to this question lies in the proposition that the grant of federal funds for airport construction requires a local sponsor authorized to enter into agreements with the Civil Aeronautics Administration, and with the State Board of Aeronautics. * * . ”, and made clear its holding by the use of this language: ‘ ‘ Taking, as we do, an overall view of the case, as presented by this certificate, we hold that a resort to any general law will not suffice to protect the rights of the parties.” There is no similar situation disclosed by the record in either of the instant proceedings. Here, instead of several independent and diverse public authorities, the principal participants in the undertaking are the County Court of Greenbrier County and its statutory creation, the airport authority, whose members are selected and approved by the county court, and that authority is necessarily subject in some degree to its direction and control.
The justification for the enactment of the special act relating to the Kanawha County Public Library and the considerations which distinguish the Kanawha County Public Library case from the instant litigation are stated in the opinion in that case in this language: “Certainly it could not be seriously contended that a general law would be proper to attain the results sought by the Legislature in requiring the respondent, the Board of Education and the City of Charleston, to make certain contributions for the support of a public library which has been in existence for more than fifty years. In many of the counties, there is no *494public library. ’ ’ The situation disclosed by the quoted language shows clearly that as there was no public library in many counties and as the situation in connection with the Kanawha County Public Library was unusual and unique, a general law would not have been proper and could not have been made applicable to the case. Consequently, the special act, Chapter 172, Acts of the Legislature, Regular Session, 1957, establishing that public library and requiring the County Court of Kanawha County to contribute to its support, was not the kind of special act which the Constitution proscribes where a general law would be proper and can be made applicable to the case.
Mandamus lies to require the discharge by a public officer of a nondiscretionary duty, State ex rel. Island Creek Coal Company v. Hanley, 149 W. Va. 107, 138 S. E. 2d 848, and the numerous cases cited in the opinion in that case; The W. E. Long Co.-Independent Bakers’ Cooperative v. Burdett, 147 W. Va. 177, 126 S. E. 2d 181, and the many cases cited in the opinion in that case; and if the statute upon which the petitioner in mandamus relies for the relief which it seeks were valid the petitioner would be entitled to the relief which it seeks in that proceeding. But inasmuch as that statute is unconstitutional, null and void as violative of the applicable provision of Article YI, Section 39, of the Constitution of this State, the petitioner has failed to show a clear legal right to the remedy which it seeks. For that reason the writ must be and it is denied and the proceeding in mandamus is dismissed.
This Court has repeatedly held that he who seeks relief by mandamus must show a clear legal right to the remedy. Syllabus 4, State ex rel. Fox v. The Board of Trustees of the Policemen’s Pension or Relief Fund of the City of Bluefield, 148 W. Va. 369, 135 S. E. 2d 262; Wilson v. The County Court of Logan County, 150 W. Va. 544, 148 S.

Tbis tbe petitioner in tbe mandamus proceeding bas failed to do.
Because of tbe unconstitutionality of tbe statute upon wbicb tbe defendants in tbe civil action rely, tbe plaintiff in that action is entitled to tbe relief for which be prays, and tbe judgments of tbe Circuit Court of Greenbrier County, wbicb denied him tbe relief to which be is entitled, are erroneous and must be reversed. Accordingly tbe judgment of the circuit court rendered July 26, 1966, denying tbe motion of tbe plaintiff in tbe civil action to vacate and set aside so much of its judgment entered July 9, 1966 as declares tbe provisions of Senate Bill No. 66, Chapter 62, Acts of the Legislature, Regular Session, 1966, to be in part constitutional and valid and denies tbe plaintiff tbe relief prayed for in bis complaint and refuses to grant to tbe plaintiff a new trial, is reversed, set aside and annulled, and the judgment entered by tbe circuit court July 9, 1966, is affirmed insofar only as it bolds Section 14 of tbe statute to be unconstitutional and invalid, but is reversed, set aside and annulled insofar as it bolds tbe statute to be constitutional and valid, except as to Section 14, and is reversed, set aside and annulled insofar as it denies tbe plaintiff tbe injunctive relief wbicb be seeks in bis complaint; and tbe civil action is remanded to tbe Circuit Court of Greenbrier County with directions that it grant to tbe plaintiff tbe relief prayed for in bis complaint, including tbe injunctive relief wbicb be seeks in that proceeding.
