West Ham United supporters have started a ballot to determine whether they want the club to move to the Olympic Stadium.
The BBC has reported that the group WHU's View is claiming that the Hammers do not want to consult with fans about a proposed move to the 2012 main stadium after the Olympics.
The group is hoping that their poll will help to influence the decision to move before it is potentially too late.
Over two home games at Upton Park, WHU's View will hand out 15,000 ballot papers.
West Ham has said it will carry out a ballot of its fan's opinions if it is chosen as the successful bidder on the 21 May.
But Peter Caton, of WHU's View, said: "If the club wins the bid and the keys are handed over, we don't believe that the club are then going to want to ask supporters because it'll be a fait accompli."
West Ham were initially awarded the stadium in a partnership with Newham council in October last year, but the deal fell through after complaints to the European Union that a £40m loan from Newham was tantamount to illegal state aid.
