This is the first update to the Code of Laws of the game since 2000. The new code makes umpires more powerful with regards to dealing with poor behavior by players.
Sending a player away from the field temporarily will be known as a “level three” sanction. In such a situation, the umpire will signal the first gesture by raising both hands and spreading all fingers spread to the height of their shoulder with their palms facing towards the scorer.
Sending a player away permanently will be classified as a “level four” sanction and will be the most severe of penalties that umpires will be empowered with as per their new powers. To signal the same, they will have to point their index finger to the scorer and hold their arm outstretched to the side of their body.
