17.1 Replacing balls (rule U 1) 

The decision where to replaced balls lies only with the Referee. In some circumstances the Referee may choose to ask advice regarding the position of balls, but the final decision must lie with the Referee. 

No matter how widely balls are scattered the Referee will still replace them, to the satisfaction of the referee. There is no provision for a re-stack because of outside interference. 

17.2 Chalk on the table (rule U 2) 

The Referee should always ensure that chalk is removed. 

It is only if the Referee believes that chalk, or other foreign matter, is being used to mark the table that the Referee shall issue a verbal warning. Three warnings in the same frame will result in loss of frame.
