The wrestlers have beaten the environmentalists in the latest round of the fight over the initials WWF.
The World Wildlife Fund had been seeking damages against the World Wrestling Federation for breaching a 1994 agreement over the rights to the WWF name.
But the Court of Appeal ruled that the World Wildlife Fund had “abused the processes of the court” by raising its damages claim in 2004 rather than in 2001, when the fund first won its injunction against the wrestlers.
Lord Justice Chadwick said: “The abuse, as it seems to me, lies in seeking now to pursue a claim for Wrotham Park damages in these proceedings after inviting Mr Justice Jacob to decide the issue which was before him in October 2001.”
Wrotham Park damages are calculated by working out how much it would hypothetically cost to buy out the original agreement.
The amount of damages that the World Wrestling Federation will have to pay to the World Wildlife Fund for improper use of the famous initials is still undecided following the ruling.
It is understood World Wildlife Fund could take the case to the House of Lords.
K&L Gates London litigation head John Magnin acted for the wrestlers, instructing Christopher Carr QC and Guy Hollingworth at One Essex Court.
The chambers is set to appoint a new lead silk for the case after Christopher Carr QC passed away at the beginning of the year.
Edwin Coe senior partner Chris Berry instructed Mark Brealey QC and Sara Lee at Brick Court Chambers for the World Wildlife Fund.
