Law 19.8 Overthrow or wilful act of fielder:
If the boundary results from an overthrow or from the wilful act of a fielder, the runs scored shall be:
any runs for penalties awarded to either side;
the allowance for the boundary; and
the runs completed by the batsmen, together with the run in progress if they had already crossed at the instant of the throw or act.
