360 So.2d 415 (1978)
AM FI INVESTMENT CORPORATION et al., Appellants,
v.
Jack KINNEY, Zearl Lancaster, Marvin G. Beck, Charles Deese and Kenneth Kelson, As and Constituting the Board of County Commissioners of Escambia County, Florida and Escambia County, Florida: Appellees.
No. 52407.
Supreme Court of Florida.
June 8, 1978.
J. McHenry Jones of Jones & Welch, Pensacola, for appellants.
Robert L. Shevin, Atty. Gen. and Larry Levy, Asst. Atty. Gen., Tallahassee, and Joe J. Harrell of Harrell, Wiltshire, Stone & Swearingen, Pensacola, for appellees.
HATCHETT, Justice.
Chapters 76-368 and 76-371, Laws of Florida, Special Acts, provide for repayment by the county to leaseholders on Santa Rosa Island an amount equal to all ad valorem taxes, for county and school purposes paid by them on their possessory interests from 1972 through 1974.[1] The trial court found that these acts violated the state constitution, and granted final summary judgment for appellees. We have jurisdiction pursuant to Article V, Section 3(b)(1), Florida Constitution (1968). We affirm the trial court's order holding these special acts to be unconstitutional on the grounds that they provide for an indirect exemption from ad valorem taxes not authorized by our state constitution and provide for refund to leaseholders of ad valorem taxes lawfully paid during 1972, 1973, and 1974.
Recently, in Archer v. Marshall, 355 So.2d 781 (Fla. 1978), we determined that a similar special act was unconstitutional because it unlawfully provided for an indirect exemption from ad valorem taxes for certain leaseholders on Santa Rosa Island. There, we also concurred in the trial court's conclusion that the legislative determination which found the county to have been unjustly enriched in an amount equal to the ad valorem taxes paid by island leaseholders had no reasonable foundation in fact. The act held unconstitutional in Archer involved *416 a reduction in future rental payments for leaseholders in amounts equal to ad valorem taxes paid by them during the previous year. The special acts involved in this case involve retroactive payment of tax monies paid or owing by Santa Rosa Island leaseholders for 1972 through 1974. The trial court recognized that this court had previously held in Straughn v. Camp, 293 So.2d 689 (Fla. 1974) that the Santa Rosa Island leasehold interests were not performing or serving a public purpose. The trial court further determined that the overall effect of these two special acts is to relieve the Island leaseholders from ad valorem tax burdens for these previous years. We agree with the trial court that the Florida Constitution requires that all property used for private purposes bear its just share of the tax burden for the support of local government and education, with certain exceptions specifically enumerated in the constitution.
Accordingly, for these reasons and the reasons set forth at length in Archer, we affirm the trial court's order and hold Chapters 76-368 and 76-371, Laws of Florida, Special Acts, violate Article VII, Section 3[2] and Article III, Section 11(a)(8),[3] Florida Constitution (1968), and are invalid.
It is so ordered.
OVERTON, C.J., and ADKINS, BOYD, ENGLAND, SUNDBERG and ALDERMAN, JJ., concur.
