The Emirates Elite Panel of ICC Referees is composed of former international cricket players who are appointed by the ICC to oversee all Test match and One Day International cricket matches in the capacity of Match referee. The referees are ultimately in charge of all international cricket matches, and act as the ICC's representative at the grounds. In addition they are responsible for imposing penalties for infringements of the ICC Code of Conduct, and so being ex-international cricketers they can ensure that the punishments dealt out are just. The referees also form part of the ICC's umpire performance review, submitting reports about the umpires after each match.
