And Everton chairman Bill Kenwright now faces the prospect of having to stage an extraordinary general meeting of the club after shareholders opposed to the move joined forces to gather a petition.
Under Everton's articles of association, a mandate from 20% of shareholders is required for an EGM to be called.
And Mark Rowan, Everton's head of media and communications, said: "The club can confirm that we did receive a petition from shareholders.
"There will now be a process of authentication and validation of the names on petition against the share register.
"Once we ascertain the accuracy of the names then we have 21 days from receipt to announce a date for an EGM."
Knowsley Council have approved the scheme - which would result in the club linking up with supermarket firm Tesco - and are also now waiting for Government approval.
Liverpool City Council has failed to come with a site and package suitable for Everton and the club insists the redevelopment of Goodison Park is unworkable.
Sharing Liverpool's proposed new stadium in Stanley Park has also failed to win the approval of both sets of fans as well as the two clubs.
Shareholders spokesman Mark Grayson wants a debate on the issue, regardless of whether the plans are "called in" or not.
He said: "Our primary concern is that we feel that the club promised a world-class and effectively free stadium with the best transport links in the UK.
"We now know through the Tesco-led planning application that the stadium will only be of 'mid-level quality' that could add a further £78m to the club's existing debt. It is our intention to have a debate regardless of whether it gets 'called in' or not."
