Wimbledon organisers have been fined by the Women's Tennis Association for banning Russian and Belarusian players from this summer's grass court events.
Both the LTA and All England Club have appealed the fines.
The fines will have to be paid in full before any hearings can take place.
AELTC chief executive Sally Bolton told reporters on Monday the organisation is "deeply disappointed" by the tour's reaction.
Asked about the fines, she said: "I think the first thing to say is that it is the subject of a legal process so I can't comment specifically on that.
