The City of Jacksonville is governed by and acts under Chapter 3775, Acts of 1887, as from time to time amended and supplemented by subsequent Acts of the Legislature. By its charter it is authorized to own, operate and maintain a municipal electric light plant and has done so for many years last past.

On January 12, 1937, the Jacksonville City Council (the municipality's legislative body) duly enacted an ordinance No. X-118, as follows:

"AN ORDINANCE Providing for the Construction of Extensions and Improvement to the Municipal Electric Plant of the City of Jacksonville, Florida, so as to Increase the Appliances for the Manufacture and Distribution of Electricity as may be Necessary to Furnish Same to Those Taking and Using such Electricity; and for the Issuance of $1,250,000.00 Revenue Certificates of the City of Jacksonville, Florida. Payable Solely from the Revenues Derived from the Operation of said Electric Plant to Finance the Cost of Such Construction.

"BE IT ORDAINED BY THE MAYOR AND CITY COUNCIL OF THE CITY OF JACKSONVILLE: *Page 566

"SECTION 1. It is hereby ascertained, determined and declared that:

"(a) The City of Jacksonville, Florida, (hereinafter called the `City') now owns, operates and maintains a municipal electric plant; the construction of which was financed by the issuance of general obligation bonds of said city, for the payment of which bonds said City was required by law to levy and collect an ad valorem tax upon all taxable property located within the territorial confines of said city.

"(b) The net revenue of such Electric Plant during the last four fiscal years has amounted to the following sums:

Fiscal Years Net Revenue

1932 .............................. $1,869,555.00 1933 .............................. 1,828,217.00 1934 .............................. 1,715,543.00 1935 .............................. 1,756,785.00

and during the first ten months of 1936 has amounted to $1,566,878.00. The estimated net revenue of said Electric Plant above all expenses of operation and other charges thereon in each fiscal year after the construction of the said extensions and improvements to said Electric Plant hereinafter referred to, is in excess of the amount to become due in each such fiscal year for principal and interest of the certificates hereinafter provided for.

"(c) It is necessary and desirable to construct extensions and improvements to said Municipal Electric Plant, such extensions and improvements to consist of new turbine and boilers and auxiliary equipment so as to increase the appliances for the manufacture and distribution of electricity *Page 567 as may be necessary to furnish same to those taking and using such electricity.

"SECTION 2. For the purpose of financing the cost of constructing said extensions and improvements, there shall be issued negotiable Electric Revenue Certificates of the City of Jacksonville, Florida, (hereinafter called the Certificates) in the aggregate principal amount of $1,250,000.00 which certificates shall be dated May 1, 1937, in the denomination of $1,000.00 each, numbered from 1 to 1250, both inclusive, in order of maturity, shall bear interest at a rate not to exceed the rate of six (6%) per centum per annum, to be definitely fixed by the City Commission, approved by the Mayor and concurred in by the City Council of said City, such interest payable semi-annually on November 1, and May 1 in each year, first interest being payable November 1, 1937, payable as to both principal and interest at the office of City Treasurer in the City of Jacksonville, Florida, or at Manufacturers Trust Company, the fiscal agency of the City of Jacksonville, in the City of New York, State of New York, at the option of the holder, in such coin or currency as is, on the respective dates of payment of the same, legal tender for the payment of public and private debts; shall be registerable as to principal only at the option of the holder and shall mature serially on May 1, in the years and amounts as follows, to-wit:

That any and all sales of said certificates shall, before the delivery thereof, be approved by the Mayor and City Council.

"SECTION 7. There is hereby created and established an `Electric Revenue Certificates Sinking Fund' (hereinafter called the `Certificate Fund') into which shall be paid in approximately equal monthly installments during each fiscal year while such Certificates, or any of them outstanding or unpaid, an amount equal to one hundred per cent (100%) of the amount required to pay:

"(1) The next maturing installment of principal of any of said Certificates.

"(2) The interest payments to fall due on all outstanding Certificates up to and including the date of the next maturing installment of principal of any of said Certificates, and

"(3) The monies in said Certificate Fund shall be used solely for the purpose of paying the principal of, and the interest on, the Certificates and for no other purpose. All monies in said Certificate Fund shall be deposited in a bank, or banks, which are members of the Federal Reserve System and shall be continuously secured by direct obligations of the United States of America, which obligations *Page 575 shall be at all times at least equal in market value to the amount of monies in said Certificate Fund.

"SECTION 8. The City hereby covenants and agrees with the holders of such Certificates that while any of the Certificates or coupons issued hereunder are outstanding and unpaid;

"(a) The City will maintain the Municipal Electric Plant in good condition, and operate the same in an efficient manner and at reasonable cost.

"(b) The City shall fix and maintain rates and collect charges for the facilities and services afforded by the Municipal Electric Plant which will provide revenue sufficient at all times to pay the cost of operation, maintenance and repairs of and all other charges against said Municipal Electric Plant and to maintain the certificate Fund as hereinbefore provided by Section 7 hereof. The City will make reasonable payment into the Revenue Fund for the facilities and services afforded to the City and all departments thereof by the Municipal Electric Plant.

"(c) The City will not sell, mortgage, lease or otherwise dispose of any property essential to the proper operation of the Municipal Electric Plant.

"(d) The City will maintain insurance on the Municipal Electric Plant of the kind and in an amount which usually would be maintained by private corporations owning and operating a similar undertaking.

"(e) The City will keep proper books of record and account, separate from all other records and accounts, in which complete and correct entries shall be made in accordance with standard principles of accounting, of all transactions relating to the Municipal Electric Plant. The City shall furnish to the holder of any of the Certificates *Page 576 at the time outstanding at the written request of such holder, not more than thirty days after the close of each six month fiscal period complete operating and income statements of the Municipal Electric Plant in reasonable detail covering such six months period, and not more than sixty days after the close of each fiscal year complete financial statements of the Municipal Electric Plant in reasonable detail covering such fiscal year and certified by independent auditors if so required.

"(f) Any holder of any Certificate issued hereunder shall have the right at all reasonable times to inspect the Municipal Electric Plant and all records and accounts thereof. None of the foregoing covenants shall be construed as requiring the City to expend any funds other than the revenues derived from the operation of the Municipal Electric Plant, except for the payment by the City of a reasonable amount for the facilities and services afforded the City and all departments thereof by such Municipal Electric Plant.

"SECTION 9. No taxes shall ever be levied and no monies shall ever be taken or diverted from any funds of the City for the payment of the principal or of interest on the Certificates issued hereunder except as hereinbefore expressly provided.

"SECTION 10. All ordinances and parts of ordinances in conflict herewith are to the extent of such conflict hereby repealed.

"SECTION 11. This Ordinance shall be in force and effect from and after its passage by the City Council, approved by the Mayor and due publication."

Proceedings had under the foregoing ordinance have culminated in a decree of the Circuit Court of Duval County validating $1,250,000.00 revenue certificates proposed to be *Page 577 issued in accordance therewith. That decree is now before this Court for review upon the appeal of an intervening taxpayer who unsuccessfully objected in the Court below to the validation of said certificates. His assertion of the invalidity of the proposed certificates is bottomed on statutory as well as organic provisions alleged to be violated, but principally upon the broad constitutional ground that the proposed certificates about to be issued are in contemplation of law municipal bonds that have not been balloted upon or approved by the affirmative vote of a majority of the freeholder electors of the City of Jacksonville cast in accordance with the requirements of Amended Section 6 of Article IX of the Constitution of Florida.^*

The jurisdiction of this Court to entertain the appeal and to review the record and proceedings had in the Circuit Court, has been properly invoked by appellant pursuant to the judicial validation of bonds statute and the course of nisi prius and appellate provided for thereunder. See Sections 5106-5112 C.G.L., 3296-3302 R.G.S.

In passing upon the objections raised the Circuit Court found as matters of law and fact the following: *Page 578

(1) That the revenue certificates sought to be validated do not come within the purview and meaning of Section 6 of Article IX of the Constitution of the State of Florida, not being bonds or general obligations of the City of Jacksonville but upon the contrary, certificates of indebtedness secured solely by the net revenue of petitioner's electric plant and for which no tax may ever be levied.

(2) The charter authority of the City of Jacksonville to maintain a municipal electric light plant in its proprietary capacity authorizes the City to anticipate its electric revenue collections in order to raise funds for essential additions to its plant.

(3) That the extensions and improvements sought to be financed by the issuance of said electric revenue certificates are such increased appliances for the manufacture and distribution of electricity as may be necessary to furnish the same to the takers thereof, and no more, and therefore come within the exceptions of the general provisions of Section 1929, Revised General Statutes of the State of Florida, 1920.

(4) That the provisions of Section 1 of Chapter 4239 of the Acts of the Legislature of the State of Florida, 1893, do not apply to the certificates herein sought to be validated, the Supreme Court of Florida having so held in Ricker v. State of Florida, 93 Florida, page 199.

(5) That the provisions contained in the several ordinances and resolutions of petitioner mentioned neither constitute exclusive pledges or limit such pledges in the future of the net revenues of petitioner's electric plant, but upon the contrary, are mere reiterations of the general pledge contained in Section 81 of the Charter of the City of Jacksonville, both prior to and after amendment, the *Page 579 same having been so held by the Supreme Court of Florida in the case of Boatright v. City of Jacksonville, 117 Fla. 477.

(6) That the electric revenue certificates herein sought to be validated are to be used for the purpose of raising funds necessary in order to finance the cost of installation of new turbine and boilers and auxiliary equipment necessary for the continued operation of the said electric plant and that the issuance of said electric revenue certificates and the improvements financed by the sale thereof will save, preserve and secure said electric plant for the benefit of petitioner, its citizens and any and all persons financially interested therein by ownership of bonds secured by the income thereof or otherwise, and that all of said bonds heretofore issued by petitioner are not only secured by the net revenues of the electric plant of petitioner but also of the Municipal Docks and Terminals, the Municipal Waterworks, and the full taxing power of the petitioner; that therefore the pledge of the net income of the said electric plant to secure the payment of the electric revenue certificates hereby sought to be validated is a superior and paramount pledge and a paramount lien to all other pledges of or liens upon said net revenues of said electric plant.

(7) That the estimated revenues of petitioner's several utilities, its Municipal Electric Light Plant, Municipal Docks and Terminals and Municipal Waterworks, based upon past performance, are ample to retire not only the outstanding bonded debt of the petitioner, both principal and interest, maturing during the years 1938 to 1949, both inclusive, together with the certificates hereby sought to be validated, without pledging the rate-making power to be exercised in the future. Especially is this true in view of the fact that the entire taxing power of the petitioner is *Page 580 also pledged to secure its present bonded debt, which taxing power is unlimited.

It thereupon entered its decree of validation to the effect that "the petitioner herein, has full, adequate and lawful right, power and authority to issue and sell Electric Revenue Certificates of the City of Jacksonville, Florida, in the total principal sum of One Million, Two Hundred and Fifty Thousand Dollars ($1,250,000.00), the denomination and maturity, bearing the interest and payable, as set forth at length in Ordinance No. X118."

The obligation of the proposed revenue certificates is against the City of Jacksonville in its public corporate capacity as proprietor of an existing municipal electric generating and distribution system that the city is authorized, and indeed required, by law to keep and maintain in a reasonably high state of productive efficiency for the utility and benefit of the city's inhabitants, and for the accommodation of those of its customers with whom it has authority to deal in a business way.

There is neither incorporated in the certificates nor implied therein, any undertakings to mortgage or encumber the plant or system itself. Nor is there pledged thereby the taxing power of the City of Jacksonville, nor undertaken to be obligated any municipal revenues otherwise derived than from the particular existing utility system designed to be thereby rejuvenated, enlarged, extended and improved.

The practical operation and effect of the scheme of financing contemplated is the negotiation and sale of the involved negotiable obligations only upon condition that the same shall be payable solely out of the anticipated income to be derived from the city's existing utility plant and distribution system. And this is to be done only that needed *Page 581 funds may be realized from such flotation to be presently invested in and added to that same system as a result of the consummation of this particular plan of funding. Such certificates are therefore not bonds within the restrictive provisions of amended Section 6 of Article IX of the State Constitution and may be lawfully issued and sold by the City of Jacksonville absent a submission of the proposition to the city's freeholder electors under said Section and Article of the Florida Constitution.

Rep. 363.

The remaining questions raised and argued upon behalf of appellant as grounds for reversal have been deliberated upon by the Court, but we find thereon no occasion for additional discussion other than to say that none of them, in our opinion, constitutes ground for setting aside or modifying the validation decree appealed from, which decree is not only sanctioned by the constitution and statutes of the State of Florida but obviously correct in the light of prior decisions of this court to which reference has hereinbefore been made. See also: Boatright v. City of Jacksonville, 117 Fla. 477, 158 Sou. Rep. 42; Ricker v. City of Jacksonville, 93 Fla. 199, 111 Sou. Rep. 552. There is nothing in the cited case of City of Jacksonville v. Renfroe, 102 Fla. 512, 136 Sou. Rep. 254, to militate against the views hereinabove expressed.

It is therefore considered, adjudged and decreed by this Court that the validation decree of the Circuit Court of Duval County, in manner and form as entered and appealed from be, and the same is hereby affirmed, and that mandate in conformity with this judgment do issue within ten days as provided for by Section 5108 C.G.L., 3298 R.G.S., chapter 11854, Acts 1927, if no petition for rehearing has been filed within that period. *Page 583
