Thidiela is fighting his battle in court after feeling hard done by the Premier Soccer League.
After Leopards purchased the status of All Stars in 2023, they assumed the club's financial liabilities and a reported subsequent FIFA transfer ban.
Leopards were forced to play the first four matches of their season with a depleted squad and were ultimately relegated.
Thidiela has since taken his case to the Court of Arbitration for Sport.
"I was demoted two years ago unlawfully," Thidiela said in the Sowetan. "The question today is, who banned Leopards and for what?
"I'm not relegated, and I'm not going to play in the ABC Motsepe League.
"The case is with CAS [the international court of arbitration for sport] to decide — it isn't for the PSL to have decided already. FIFA said there is no ban for us."
"[After that] the league gave me the [registration] cards the same day we received the letter on September 30 from FIFA. Before that we wrote a letter to ask if we can register the young players from our academy, and they [PSL legal] refused," Thidiela added.
"And on September 30, they [FIFA] said Black Leopards are not banned — immediately the same day when I got a letter from FIFA, the league called us to say come and collect the cards.
"The ban was over after we played four games."
