The

U.S. Supreme Court

on Monday declined to take the ongoing legal battle over advertising between

Pizza Hut

and

Papa John's

(PZZA) - Get Report

a step further, as it turned down the Hut's request for an appeal.

The court dismissed the request without issuing comment. Pizza Hut, which is part of

Tricon Global

(YUM) - Get Report

, claimed the jury reversed "well-settled principles in false advertising law."

The suit, first initiated in 1998, centered around Papa John's advertising slogan: "Better Ingredients, Better Pizza." A jury initially found in favor of Pizza Hut, awarding almost $468,000 damages, and Papa John's was barred from using the slogan, but the ruling was overturned by an appellate court. In the appeal, the court found that the slogan by itself was misleading, but didn't have a major impact in the purchasing decisions of consumers.

"No advertiser has ever been able to defend a campaign that is deceptive on the basis that the public doesn't care," Pizza Hut said in a statement. "We are disappointed the court did not seize this opportunity to clarify this matter for the benefit of consumers and responsible advertisers, alike."

Representatives from Papa John's weren't immediately available.
