Evans, P. ¿T.
(Alter stating the facts.) 1. The predicate of this action is the 11th section of the leasing act of 1889, which provides, “that said lessee or lessees shall he required to pay all taxes and assessments upon the property of this State in the State of Tennessee, and in Georgia upon all property owned or controlled by them, not received from the' State, and such further taxes upon their income as is now paid by the Central Eailroad and Banking Company.” The ultimate result sought to be attained is the collection of taxes alleged to be due to the State under this section. In view of the demurrer challenging the right of the State to collect taxes by civil action, it becomes necessary to determine whether the tax referred to in this section is a tax in the strict sense of the word or simply a contractual obligation. In approaching a solution of this question, it should be kept constantly in mind that the, lessee’s rights and obligations are not primarily founded in the contract of lease, but in the act of the legislature authorizing it. That act defined the terms upon which the State road was to be leased, and the contract was executed agreeably to it. The State declared in the legislative enactment its policy with regard to the public burdens to be imposed on the lessee, and the contract of lease executed pursuant to the act was a guaranty that no greater public burdens would be exacted. W. & A. R. R. Co. v. State, 54 Ga. 429. It becomes then a question of- legislative intention as to the nature of the taxes mentioned in section 11. In this section the legislature was dealing, with public burdens. It had already been provided, in another section of the act, that the lessee was to pay a monthly rental, the minimum of which was fixed. It was therefore important for the State, in order to receive the greatest possible benefit from competitive bidding, to declare what public burdens would be exacted of the lessee. If the State clearly .defined these burdens and limited itself to exact no more, this element of certaintji- respecting the burdens of sovereignty which- the lessee was to bear tended to increase the rental value. In proportion as the burdens were more onerous, it is reasonable to infer that the rental price would be depressed. The matter of rent and the matter of taxes were treated in the act as standing on distinct and difieren t footings; they were dealt with in separate sections. The money which the State receives as monthly rental is the State’s income derived from (be ownership of the leased property; the money *625which the State receives in the public coffers in the exercise of sovereignty, is the taxpayer’s tribute to" that sovereignty. The requirement to pay the acl valorem tax on property not received from the State, but used in the operation of the road, referred to a tax in its strict sense. Ts there any difference in the quality of the income tax required of the lessee in the same sentence of the section? One of the arguments advanced to support the theory that the requirement of a pereentum of the lessee’s annual income is not the exaction of a tax is that it was beyond the constitutional power of the legislature to levy an income tax. The constitution of this State provides that “all taxation shall be uniform, upon the same class of subjects, and ad valorem on all property subject to be taxed within the territorial limits of the authority levying the tax, and shall be levied and collected under general laws.” Civil Code (1910), § 6553. It is our opinion that this provision has no reference to the levying' of a tax upon public property. The ordinary meaning of taxation is a charge levied by the sovereign power upon the property of its citizen; it is not a charge upon its own property. People v. McCreery, 34 Cal. 432, 456. The general rule is that public property is not subject to taxation. “This immunity rests upon the most fundamental principles of government; being necessary, that the functions of governmeni/be not unduly .impeded, and that the government be not forced into the inconsistency of taxing itself in order to raise money to pay over to itself.” Penick v. Foster, 129 Ga. 217 (58 S. E. 773, 12 L. R. A. (N. S.) 1159); Georgia Fire Ins. Co. v. Cedartown, 134 Ga. 87 (67 S. E. 410). The quoted provision of the constitution relates to the collection of taxes from property other than public, and has no application to the impressment of a tax upon the public property of the State. The case presented is not that of a perpetual leaseholder, where the tenant is the virtual owner of the property, entitled to its use forever and subject to pay taxes thereon as owner, as was the case in Wells v. Savannah, 87 Ga. 397 (13 S. E. 442). In making the lease the State reserved the right of forfeiture on broken conditions subsequent, and imposed terms and conditions indicating that no estate was intended to be conveyed to the lessee, but that the lessee was to have only a usufructuary interest during the lease period. The power of the legislature to impose taxes is inherent, and is only circumscribed by the organic law. When the *626legislature authorized the contract which permitted the lessee to have possession of the State’s property for a term of years, it was within the constitutional sphere of legislative action either to - expressly preserve the status of public property with reference to immunity from taxation, or to stipulate that the lessee should pay a specific tax. The latter course was adopted, and a specific tax, to wit, a tax upon the lessee’s income (such as was paid hv the Central'Railroad and Banking Company), was levied.
2. Having reached the conclusion that the covenant in the lease contract, binding the lessee to pay such taxes upon the lessee’s income as was paid by the Central Railroad and Banking Company at the time of the lease, is a covenant between the State and the lessee, fixing and limiting the character and amount of the tax to he exacted by the State as a sovereign, in contradistinction to an obligation in the nature of a debt springing from and supported by the contract, we will next consider the right of the State to enforce collection of it, and also of the ad valorem tax alleged to be in default, in a civil action. There are two -lines of authority on this proposition. Some courts hold that taxes are in the nature of a debt due by the citizen to the State, enforceable by an action of assumpsit; and that the common-law right of the State to collect a tax by-a civil action is not surrendered by the legislature in furnishing specific remedies, unless expressly so stated in the statute. On the other hand, the weight of authority is to the point that when the statute undertakes to provide remedies, and those given do not embrace an action at law, a common-law action for the recovery of the tax as a debt will not lie. 1 Cooley on Taxation, 17; Burroughs on Taxation, 254. It was a rule at common-law that where a statute creates a right and provides a particular remedy for .its enforcement, the remedy is generally exclusive of all common-law remedies. When this rule is considered in connection with the genius and spirit of our American institutions, its application to the collection of taxes, where adequate statutory remedy is provided, can not be doubted. A most distinctive feature of the constitution of the Hnited States and of this State is the division of the powers of government into three separate departments, — executive, legislative,, and judicial. It was designed and intended that one department should not usurp the ordinary functions of the other's, hut that all three should act in harmonious relation. So, *627when the legislature authorizes a tax for governmental purposes and provides an adequate remedy for its collection by administrative officers, the necessary intendment is that the collection of the tax is exclusively confided to that administrative department of the government. And it has been held by this court that when the statute undertakes to provide remedies for the collection of taxes, and those given do not embrace an action at law, a common-law action for the recovery of taxes as a debt will not lie. DuBignon v. Brunswick, 106 Ga. 317 (32 S. E. 102); State v. S. W. R., 70 Ga. 33.
However it is contended that the petition presents equitable fea-, tures, and that in equity an action may be maintained by the State to collect its revenue. It would be idle to enter into a discussion of possible differentation between an action in which the equitable powers of the court are invoked and one only seeking purely legal relief. Whatever equitable relief is asked in the petition is predicated upon the erroneous construction of the lease act that the provision for the payment of taxes upon the income of the leased property is a debt arising from the'contract executed pursuant to the act, and not a tax.
The General Assembly has enacted an elaborate scheme for the assessment of the property of railroad companies and the collection of any tax lawfully levied. Provision is also made for the collection of back taxes from delinquent or defaulting railroad companies; and whatever infirmity may have been in the original statute with reference to assessment without opportunity of the delinquent taxpayer to be heard, as pointed out by the yuprenio Court of the United States in Central of Georgia Railway v. Wright, 207 U. S. 127 (28 Sup. Ct. 47, 52 L. ed. 134), has been relieved and cured by the amendment of 1908 (Acts 1908, p. 25). The amendment relates to the remedy and does not impair any right of the taxpayer. It only supplied a defect in the existing law. The law as amended is applicable to the collection of back taxes without regard to the time of their accrual, if within the statute of limitations. DuBignon v. Brunswick, supra.
3. Another insuperable objection to this effort to collect a tax by civil- action in the nature of an action of debt is that there has been no assessment. An assessment is indispensable in proceedings to enforce the collection of taxes. Until an assessmnt of a *628per centum, tax is made, the amount of the tax is not fixed. Tax proceedings are in invitum, and to be valid the statute must be followed, and no tax on property can be collected until it has been assessed. Hawkins v. Jonesboro, 63 Ga. 527. Should the legislature pass a tax law which inadvertently omits the mention of a return, but requires payment of the tax to be made to a particular officer, it means by necessary implication that the return is to be made to the officer who makes the assessment of the tax. Smith v. Goldsmith, 63 Ga. 736. But, as already indicated, the legislature of this State has provided for an assessment by a particular officer; and the rule is well grounded and followed in this State that where the statute provides for an assessment by a ministerial officer, the assessment must be made by him and not by the courts. Bohler v. Verdery, 92 Ga. 719 (19 S. E. 36); Norris v. Coley, 100 Ga. 553 (28 S. E. 222).
Í. The petition contains a very general allegation suggestive that a recovery of damages for breach of contract is sought. There is, however, no distinct allegation of any breach of the contract. It is alleged that the lessee had “made divers contracts of sublease unknown to the State, and that the lessee has collected from said sublessees from time to time large sums of money. Some of these subleases it is believed and charged were in violation of the contract, and some were not; but the State has no knowledge or means of knowledge as to which of said subleases were in violation of the contract and which were not, and how much it derived from the respective contracts, nor how much thereof was accounted for in the annual statements touching the income tax.” It is a fundamental rule of pleading that in order for a plaintiff to recover .damages for a breach of contract, the specific breach must be alleged, and the general allegation that the lessee had perhaps breached' the contract by making unauthorized subleases is too vague to support the petition as one claiming damages for breach of contract.
5. As the suit is not maintainable for the collection of taxes, it can not be retained as one for the discovery of the property claimed to be subject to taxation. Furthermore, as the petition contains no sufficient averments of a breach of contract to support a decree for damages, it can not be maintained for the discovery of possible breaches. These conclusions result from the well-settled *629rule that where discovery is merely incidental to the relief prayed, the suit can not be maintained when the plaintiff is not entitled to the relief praj^ed.
