Kuwait has filed a lawsuit in a Swiss court seeking $1bn (£670m) in damages from the International Olympic Committee (IOC) over the suspension of its Olympic committee.
The IOC and world football governing body Fifa suspended Kuwait in October citing domestic laws that permit government interference in sports.
But Kuwait says the IOC ban was imposed without proper investigation.
It says it may not be allowed to take part in the Rio Olympics in August.
“It’s totally unacceptable that Kuwait is treated in this unfair way and barred from international sports activities without any appropriate probe being conducted,” Information Minister Sheikh Salman al-Humound Al-Sabah reported to the reporters on Wednesday.
