The London club released Mutu in 2004 following the Romanian striker's positive drug test and sought compensation, which they were granted by FIFA in 2013.
However, a statement from Juventus on Wednesday read: "Juventus Fooball Club announces today that the Court of Arbitration for Sport in Lausanne has notified us of the decision made by the arbitrators in the dispute that pitted Chelsea against Juventus regarding the signing of Adrian Mutu.
"The arbitrators have completely dismissed the demands made by Chelsea FC, ordering them (the London club) to play the legal costs of the case.
"This ruling has no effect on the financial balance of Juventus Football Club because the club, fully aware of being in the right, chose not to allow for any risk in funds over the developing litigation."
