The date was confirmed two weeks ago and Derby were keen to see the matter sorted as Davies settles in to his new club.
However, Derby were informed yesterday that the meeting was postponed due to the Football League Board Director and Tranmere chairman Lorraine Rogers apparently being on holiday, though this is yet to be confirmed.
Adam Pearson, Chairman of Football Operations at Derby said: "Derby County is staggered at this decision which extends the uncertainty for the player concerned and makes a mockery of all the time and work the club has undertaken in preparing for this assessment tribunal over the summer months."
Derby will now have to wait for a new date to be set before they will know how much compensation Tranmere are due.
Pearson added: "It is important to point out that the postponement of the tribunal does not affect Steve Davies' registration with Derby County Football Club."
