The umpires' decision to check for no ball in the first instance was controversial. Although the umpires instructed the players to return to their field, they were still in an uncomfortable situation. As the players were agitated, Assistant Coach Praveen Amre ran onto the field to challenge the umpires. The game continued with the crowd shouting "cheaters!" DC eventually lost the match by 15 runs. This incident was very similar to one Mahendra Singh Dhoni was involved with many years ago.
Law 21
A ball is a valid ball if it has a batsman's opportunity to strike it, is a No ball, or a wide ball, and is declared by the umpire. In most cases, a valid ball is a delivery that is a wide or a No ball. Also, a valid ball could be any delivery that is not allowed to be called wide or No. If a batsman gets stranded, he or she is out.
Law 27
A no ball can be defined as a ball that is not thrown in the striker's direction. This is also known as an unplayable ball, and is recorded against the bowler's record. There are exceptions to this no-ball rule. For instance, a no ball can be thrown underarm if a special agreement has been made between the captains of the teams. This has been repeated twice in international cricket.
Law 40
A No ball is a no out situation in baseball. This is when the batter does not reach the ball. This is when the batter fails to reach the ball.
Law 41
If a fielder gets distracted, the umpire must signal "dead ball" and inform the opposing umpire. A dead ball will not count as an over and the batting side is awarded five runs. The umpire must inform both the batters as well as the striker about the dead ball. It is an important rule that must be observed to ensure fair delivery.
Law 42
If a ball is not in the crease, but the bowler's backfoot is outside of the crease, the umpire can signal a No ball. During the delivery swing, the bowler must not straighten the elbow joint or reach for the shoulder. However, the definition does not prevent the bowler flexing their wrists during the delivery swing. All three conditions must be met before the end umpire can signal No ball.
Law 40 (wicket-keeper)
There are two types of no-balls called "wicket-keeper". The umpire will rule unfairly if a no-ball is used to deliberate overstep. A deliberate no-ball that breaches one of the other parts of the Law, however, will not be deemed unfair.
Law 42 (Unfair play)
If the umpires rule that one team's action is unfair in a cricket match, it is called unfair. If this happens, the umpires have the right to intervene, but they shouldn't interfere with the game's progress. For example, if a fielder deliberately lifts the seam of the ball during a delivery, this is unfair. This is a violation of the rules and the umpire will have to replace the ball.
Law 41 (fielder).
If the fielder attempts to distract the striker, the umpire must signal dead ball. The umpire must also inform the other umpire of the call. A dead ball doesn't count as an out and the batting side is given five penalty runs. The umpire must also inform the batters and the batting team of the call. If the fielder does not attempt to distract the striker, the dead ball stands.
