Flat Green (lawn) Bowls - The Wrong Bowl.
If a bowl is played out of turn the opposing slip may stop it while it is running and have it replayed in its proper order.
If a wrong bowl displaces the jack or bowl, the positions may be accepted or the end replayed.
A wrong bowl shall be replaced, where it stops, with the player's own bowl.
If a bowl is delivered out of order and the live bowls and jack have not been disturbed, the opponent bowls two successive bowls.
A player who omits to deliver a bowl may not play that bowl later in the end.
Flat Green (lawn) Bowls - The Dead Bowl.
A dead bowl is one that:
stops within 14m of the mat;
stops completely outside the rink boundaries;
is driven beyond the rink boundaries by another bowl;
finishes in the ditch without having touched the jack on the green;
rebounds from the far bank without having first touched the jack on the green.
Dead bowls are immediately removed from the rink and placed on the bank.
Flat Green (lawn) Bowls - Live Bowls.
All other bowls are live, including "line bowls" on a boundary.
The skips, (or, in singles, both players) agree when a ball is dead.
