The case was forwarded by Yanga, who insist the player breached his contract with the outfit and signed for age-old rivals, Simba, at the beginning of this season.
Despite Simba, the Tanzania Mainland League defending champions, insisting the exercise was legal, Yanga refused to accept the decision and initiated proceedings against the Ghanaian.
"Yanga would like to inform all of our members, supporters, and fans of the latest on Bernard Morrison case which is ongoing at CAS," a statement from the club, which was obtained by The Guardian, read.
The outfit noted: "Legally, we are not allowed to reveal what is going on as far as the case is going on until when the ruling will be made.''
''However, Yanga would like to inform all that what delayed the case was the preliminary objection made by Morrison to have the case handled in Tanzania.''
"After listening to both sides, CAS opted to overrule the appeal and as a result, the case will be mentioned again from June 2, 2021.''
"The club would like to confirm to all associated with it that we will continue fighting until justice is done and all will be informed,'' the statement said.
The Ghanaian midfielder left Yanga for rivals Simba SC in a controversial transfer that left his former club lodging a complaint with the Tanzania Football Federation (TFF), who later cleared him to play for Simba.
However, unsatisfied Yanga vowed to present the issue to the Court of Arbitration of Sports (CAS) in Zurich to protest the decision by the TFF.
During Yanga’s 'Mwananchi Week' celebration, which culminated a week of charity activities held by the club, which was held at the Benjamin Mkapa Stadium in Dar es Salaam, the club, through the MC of the day Maulid Kitenge, announced Morrison was still a Yanga player.
“The player listed in number 28 is Bernard [Morrison], who is still our player as we have a case in CAS, so Morrison is still our player,” Kitenge announced.
The MC's statement was well applauded by thousands of Yanga fans, who turned up for the celebrations whereas others were annoyed.
Commenting on his signing for Simba, Morrison urged Yanga to accept and move, saying it was part of football.
“It is part of the game, and I don’t take any personal offense about whatever that has been happening for a while now,” Morrison noted.
