We granted certiorari to the Court of Appeals’ decision in
Federated Mut. Ins. Co. v. DeKalb County,
In Cotton States, supra, we held the insurance companies were not liable to pay back taxes to DeKalb County for the years 1974 through 1981. We determined that the enabling statute authorizing the 1973 DeKalb ordinance levying a three percent tax on gross premiums for certain types of insurance covering property located in the county had been repealed by implication. The enabling statute, Ga. Laws 1959, p. 658 was based upon a local constitutional amendment, *523 Ga. Laws 1958, p. 582. Our rationale was that the Georgia Insurance Code, Ga. Laws 1960, p. 289 (OCGA § 33-1-1 et seq.) which, among much else, levied a statewide two and a quarter percent premium on all casualty insurance companies doing business in Georgia, was inconsistent with and contrary to the 1959 enabling statute for the DeKalb County tax and therefore repealed that enabling statute by implication.
After Cotton State’s victory, Federated Mutual began this action seeking a refund of premium taxes it paid DeKalb County (Federated Mutual acknowledged a three-year limit on refunds for taxes by virtue of OCGA § 48-5-380). The county took the position that
Cotton States,
supra, should be given a prospective only effect, thus precluding a refund of the taxes. It pointed out the test for retroactive or prospective treatment of court decisions laid down in
Chevron Oil Co. v. Huson,
Federated Mutual argues to us that we can simply ignore the decision of
Cotton States,
supra, as a precedent in this case and apply the same rationale we applied there to find that the 1960 Insurance Code repealed DeKalb’s enabling act. But we cannot simply put aside
Cotton States.
The issue of non-retroactivity is presented in a case where the principle of law relied upon is one which was established as a new principle of law in a prior decision.
Chevron Oil,
supra. A court announces a new principle of law when it either (1) overrules clear past precedent such as was done in
Mapp v. Ohio,
Judgment affirmed.
