Justice David Hammerschlag dismissed the appeal against an arbitration ruling in favour of the Australian Rugby Union that allowed the governing body to cut the Force from the Super Rugby competition.
Despite the ruling, RugbyWA are likely to continue their fight for the Force to survive with billionaire back Andrew "Twiggy" Forrest prepared to take the matter as far as the High Court.
The ARU had agreed to cut a team in March in a meeting with Sanzaar officials in London where the broader decision was made to reduce the Super Rugby competition from 18 teams to 15.
