The Qatar 2022 team deny any wrongdoing with their winning bid, saying their name has been "dragged through the mud for no reason".

November 2014 - Hans-Joachim Eckert, chairman of the adjudicatory chamber of FIFA's independent ethics committee, publishes a 42-page summary of Garcia's investigation, effectively confirming Russia and Qatar as World Cup hosts after finding breaches by them were "of very limited scope".
FIFA lodges a criminal complaint with the Swiss attorney general over "possible misconduct" by individuals but insists the investigation into the bidding process for the two World Cups is concluded. Garcia calls the summary "incomplete and erroneous" and launches an appeal against it.
