Whether Gary Forsee will take over as chief executive officer at Sprint could be decided as soon as Tuesday.

BellSouth filed suit to prevent Forsee, one of its top executives and expected heir apparent to BellSouth’s top job, from joining Sprint.

A three-day arbitration hearing before Judge William H. Webster concluded on Tuesday. A decision is expected by no later than 5 PM on Tuesday, if not earlier, according to a brief statement issued by BellSouth.
