FIFA has sent 1,300 pages of internal investigation reports into suspected bribery and corruption to Switzerland's attorney general.
However, FIFA said Friday it was legally barred from publishing the full reports or commenting on the evidence or conclusions.
The documents complete a 22-month probe by legal firm Quinn Emanuel, which FIFA retained in the fallout from United States and Swiss federal prosecutors revealing their sprawling investigations of soccer corruption in May 2015.
FIFA has said the U.S.-based law firm, whose hiring helped add $30 million to its published legal costs in 2015, is key to helping retain its institutional status as a victim of corruption and not an accomplice.
