Charters was not present as he was granted a bail variation earlier this year to reside and work in Hong Kong.
He was represented by his counsels Seforan Fatiaki and Juleen Fatiaki while FICAC was represented by the Acting Commissioner, Lavi Rokoika.
The parties appeared before Justice Pita Bulamainaivalu this morning.
FICAC will file their affidavits next Monday with Charters' counsels given 14 days after that to respond.
Charters' counsel are filing on the lawfulness of the appointment of Lavi Rokoika as the FICAC Acting Commissioner.
They say the other grounds deal with the manner in which their clients arrest, detention and charge.
Fatiaki says on the argument of bad faith, FICAC investigators stopped Charters at the airport on that night and on three occasions told him that if he was to provide them with his sources of his journalistic writings that they would let him go.
He says what the FICAC officers did not even consider was that Charters might have received it from some other third party.
Charters' counsel are arguing that at the time of his arrest and detention, FICAC did not even have grounds to arrest or charge him and have been working backwards ever since.
A mention date has also been set for 12th June.
