The Hearts board has issued a statement insisting that it remains open to a proposal to sell and lease back Tynecastle stadium.
Robinson and Foulkes do not share the same view on Tynecastle
It follows the leaking of a document, which indicated the board had "no appetite" to consider the plan.
The board had publicly declared it would consider such a plan and reiterated that on Saturday afternoon.
"Hearts remain open to the presentation of any detailed sale and lease back proposal," the statement read.
"At our meeting on Tuesday the board agreed in principle to consider a sale and lease back proposal from Leslie Deans and Robert McGrail. As yet, no such detailed proposal has been received.
"If or when Mr Deans or Mr McGrail present such a proposal to Hearts the board has asked that it is sufficiently competitive to ensure it stands proper comparison with the £22m from Cala.
"If an offer which stands comparison with the Cala bid is made it will be given full and detailed consideration by every member of the Hearts board prior to any binding decision being made.
"We understand that the preparation of such an offer can be a time consuming and complex process which is why the board has ensured a five-month breathing space before it must commit to the final acceptance of the Cala proposal."
However, the document leaked to The Herald stated that, despite their public position, the plan was not being seriously considered.
The proposal was to be considered by a working party set up to examine alternatives to moving to Murrayfield.
The working party, chaired by Lord Macaulay, was to look at the proposal at a meeting last week, but that was put off for two weeks after chief executive Chris Robinson missed the meeting.
Chairman George Foulkes told The Herald that the views in the document were not those of the entire board.
"There was some scepticism about it, but the board agreed in principle they would consider it," he said.
"Chris Robinson was asked to prepare a paper for the working party. I am not on the working party and have not seen it."
