[1] On 11 September 2021, Croissant Chebbien returned to the league following a vote by the Ordinary General Assembly of the Tunisian Football Federation.
On 18 April 2022, the match of the last round was held between Club Africain and Croissant Chebbien at Stade Hammadi Agrebi, Tunis and ended with a 1–0 win for the hosts, a result that made Croissant Chebbien relegated to the Ligue 2, but Croissant Chebbien protested the presence of Club Africain president, Youssef Elmi, on the bench despite his suspension from punishment by the Football Federation, and demanded that they would be given a penal victory, and they decided to take the case to CAS.
On 29 September, the CAS decided to reintegrate Croissant Chebbien in the Ligue 1, which forced the federation to add a 16th team for 2022–23 season so that the number of teams would be even, and the identity of this team was determined by two playoff matches, the first between Club de Hammam-Lif and Espérance de Zarzis, and the second between the winner of the first match and Étoile de Métlaoui.
On 27 March 2023, the CAS decided to give Croissant Chebbien a 2–0 penal victory.
Since this decision affects the arrangement of the table in the first round and the added points for the coronation playoff and playout, and since this decision came late and after the start of the new season, the effect of this result in the second round was not calculated.
