Action not barred as collateral attack.

- Taxpayer's petition seeking a declaration that the valuation method a county board of assessors and the development authority of the county used for leasehold estates arising from a local development authority sale-leaseback bond transaction was illegal was not barred for being a collateral attack on concluded bond validation proceedings because the challenge to the memoranda of agreement that set forth the tax assessment formula at issue would only constitute a prohibited collateral attack on a concluded bond validation proceeding if the memoranda were specifically adjudicated in the proceedings and held valid by the bond judgment, and the board and authority had to put forth evidence that the applicable bond validation orders did in fact expressly rule upon each memorandum of agreement; even if the taxpayer was barred from challenging the tax agreements on concluded bond transactions, the taxpayer also sought an injunction to prohibit the use of the formula in future bond agreements.

Use of local school taxes for redevelopment.

- School system, development authority, and others were properly granted summary judgment in a suit challenging the allocation of school taxes because the 2008 amendments to Ga. Const. 1983, Art. IX, Sec. II, Para. VII(b) and O.C.G.A. § 36-44-9(g), governing tax allocation districts, changed the law and retroactively allowed use of local school taxes for general redevelopment purposes. Sherman v. Atlanta Indep. Sch. Sys., 293 Ga. 268, 744 S.E.2d 26 (2013).

Validation not conclusive on issue of exemption from property tax.

- Two bond validation orders pertaining to a hospital authority's establishment of a continuing care retirement center did not conclusively determine, for purposes of O.C.G.A. § 48-5-41(a)(1)(A), that the property was public property exempt from ad valorem taxation; remand was required for the trial court to address taxability.
