The English FA has taken world football's governing body (FIFA) to court over the case which saw Chelsea handed a transfer ban.
In February of last year, the London club was found guilty of a serious and systemic breach of the rules regarding their dealings with overseas players under the age of 18.
Chelsea were hit with a transfer market ban for two windows as well as a fine of 600,000 (€570,000) Swiss francs although the punishment was reduced on appeal.
The Court of Arbtration for Sport (CAS) ruled that the Premier League club had only transgressed in "about a third" of the original cases regarding 150 players and halved the fine and reduced the transfer market ban to one window.
The FA was also found to have broken the rules in connection with the transfer of minors as player registrations are processed at FA level.
The FA were fined 510,000 (€485,000) Swiss francs but that was reduced to 350,000 (333,000) Swiss francs on appeal while it was also told "to address the situation concerning the international transfer and first registration of minors in football" within six months.
The case will now be heard by the CAS on 26 June.
The FA commented to ESPN: "The FA has cooperated fully with FIFA's investigation. As this is an ongoing legal process it would not be appropriate to comment further at this time."
Meanwhile, in an interview with Sky Sports, former Chelsea manager Antonio Conte has been heaping praise on former Blues skipper John Terry.
Conte also revealed that, as a thank you to Terry, he agreed to take him off in the 26th minute of his final game at Stamford Bridge against Sunderland.
"He decided he wanted this because 26 was his squad number and for me it was a pleasure to give him this opportunity," Conte added.
"I will never be able to thank him enough. He was very important for me and our team."
