Premier League clubs reacted to the Carlos Tevez row today by seeking to clear up any confusion over third party influence in the purchase of players at their annual general meeting.
West Ham escaped with a £5.5million fine instead of being docked points for signing third-party agreements in contravention of league rules when an independent commission ruled on the nature of the deals that took Tevez and Javier Mascherano - now with Liverpool - to Upton Park.
The third-party agreements were with Iranian-born businessman Kia Joorabchian and the Hammers were ordered to end the agreement by the commission. But the Hammers did not have to cancel Tevez's registration and went on to escape relegation with the Argentinian playing a key role.
The commission ruling provoked fury from the Hammers' relegation rivals including Sheffield United, who were relegated on the final day of the Premiership season.
The Premier League have since agreed to set up an arbitration tribunal to rule on the Blades' complaints over the registration of Tevez.
A Premier League statement on today's AGM said: "It was decided, for the sake of clarity, to adopt a rule making the disclosure of all documents relating to the transfer of a player's registration and any other relevant third party contracts or arrangements explicit."
