The so-called "Jackson Law" is an optional general law that may be adopted by a county or municipal legislative body by a two-thirds (2/3) majority vote.  If adopted, it provides that no new construction will be initiated for a landfill without the approval of the county legislative body unless the landfill only accepts waste generated by its owner and all such waste is generated in the same county as the landfill.  Additionally, if such proposed construction is in an incorporated area or within one mile of an incorporated area, the governing body of the municipality must also approve before construction can be initiated.  T.C.A. § 68-211-701.  Public notice and public hearings are required before the vote of the legislative body.  T.C.A. § 68-211-703.  This law states criteria that must be considered by the legislative body in determining whether or not to approve the construction. Judicial review of the legislative body's determination may be had before the chancery court for the county in which the landfill is to be located.  T.C.A. § 68-211-704. The Tennessee Court of Appeals upheld a decision by the Davidson County Chancery Court that exclusion of county and municipal landfills from application of the Jackson Law as provided in T.C.A. § 68-211-706(b) is unconstitutional as a violation of the equal protection clause since there is no rational basis for this discrimination against private landfills. However, the Court applied the doctrine of elision (removal of offending provision, exemption of public landfills) and upheld the remainder of the act. Profill Development, Inc. v. Dills, 960 S.W.2d 17 (Tenn. App. 1977).

In 2013, the Jackson Law was amended to increase the scope of the law to include a change in classification of a landfill to a classification with higher standards. However, this amendment provides that it only applies if independently approved by a two-thirds vote of the county legislative body if the county adopted the Jackson Law prior to May 13, 2013.

In a statute separate from the "Jackson Law," municipalities must obtain the approval of the county legislative body at two consecutive regularly scheduled meetings before the municipality may exercise the power of eminent domain to obtain property to be used as a landfill for solid waste disposal outside of the corporate limits of the municipality. T.C.A. § 68-211-122.
