The term “public use” does not have a precise and universally acceptable definition.  The determination of whether a proposed use constitutes a public use must be based on the facts of each case because the term must remain elastic to meet the growing needs of a complex society. 
The General Assembly adopted a restrictive definition of “public use” that is codified in T.C.A. § 29-17-102. Generally, the definition precludes the use of eminent domain for private benefit and makes exceptions for certain well-recognized public uses that normally have incidental private benefits.
As noted above, the legislative body makes the initial determination that the taking of private property is for a public use. If the property owner challenges the condemner’s right to take on the grounds that the property will not be put to a public use, the court has the right and the duty to determine whether the proposed use is a public use.  The determination by the legislative body that the proposed use is a public use is entitled to a strong presumption of correctness,  but it is not conclusive on the court.  When the court finds that the proposed use has no significant relationship to the public benefit, it must find that the condemner lacks the right to take private property under the power of eminent domain.
