In cricket, LBW is one of the most intricate and contentious methods of dismissal. It is essential in the game, particularly for bowlers who use spin and swing to trick batsmen. The LBW in cricket was created to prevent batsmen from blocking the ball with their pads to escape. Over time, innovations like the Decision Review System (DRS) have improved LBW decision accuracy and decreased umpiring errors.
Even though the LBW rules are technical dismissal, players, referees, and spectators must know it. In this article, we shall dissect the definition, guidelines, background, and function of technology in promoting more significant equity and transparency in LBW choices.
What is LBW in Cricket?
In cricket, LBW (Leg Before Wicket) is a method of dismissal where a batsman is deemed out if, after the bowler has legally delivered the ball, it strikes any part of their body (except the glove) before striking the bat and, in the umpire’s opinion, would have struck the stumps. According to the LBW law, batsmen cannot purposefully use their legs to block the ball from hitting the wicket.
Rules of LBW
According to the Marylebone Cricket Club’s (MCC) Laws of Cricket, the LBW rules include the following essential requirements:
- Ball Pitching: If the batter is not performing a shot, the ball must pitch outside off stump or in line with the stumps.
- Impact on the Batsman: The ball must strike the batsman’s body or pad in alignment with the stumps. The batsman can only be dismissed if they do not offer a shot if the impact occurs outside the off stump.
- Ball’s Path to Stumps: If the ball hadn’t hit the batsman, the umpire must be persuaded that it would have continued to hit the stumps.
- No Edge from the Bat: The batsman cannot be declared LBW in cricket if the ball strikes the bat before hitting his pad.
- No Complete Toss Above Waist: The ball cannot be deemed an LBW dismissal if it is a full toss and strikes the batsman above the waist before bouncing.

History and Evolution of the LBW Rule
To stop batters from illegally obstructing the ball with their legs, the LBW rule was first implemented in 1774. At first, the LBW law was only applicable when the ball was pitched directly into the stumps. Nevertheless, changes were made when batsmen started abusing the regulation by padding up outside the off stump.
The law was changed in 1935 to permit batsmen to be dismissed even if they failed to give a shot to deliveries pitched outside the off-stump. Batsmen were encouraged to play shots instead of defending with their legs due to this modification.
Using ball-tracking equipment (such as Hawk-Eye) to assess the accuracy of LBW calls, the Decision Review System (DRS) was implemented in 2008 due to technological advancements. This approach improved the fairness of LBW rulings and drastically decreased umpiring errors.
Key Criteria for an LBW Decision
For an LBW appeal to be upheld, the following key criteria must be met:
- Ball Pitching: If no shot is offered, the ball must land outside off stump or in line with the stumps.
- Impact on the Body: When not playing a shot, the ball must strike the batsman’s leg (or body) outside off or in line with the stumps.
- Ball Path: Following impact, the ball must move toward the stumps. To ascertain this, umpires utilize ball-tracking technology in DRS.
- No Bat Involved: It is not LBW if the ball makes contact with the bat before hitting the batsman’s pad.
- Ball Height: The batter is not out if the ball is too high, passing over the stumps. DRS aids in the trajectory analysis of the ball.
Role of the Umpire & DRS in LBW Decisions
Role of the Umpire
The on-field umpire heavily influences decisions regarding lbw in cricket rules. In real time, they have to evaluate several factors:
- Whether the ball was thrown in the right spot
- Whether the ball struck the batsman in line with the stumps
- Did the batsman make a shot?
- Was the ball on its way to the stumps?
The umpire will raise their finger to let the batsman out if they think all the requirements are met. If they’re unsure, they could declare the batsman “not out,” giving the fielding team a chance to reconsider.
Decision Review System (DRS) in LBW Decisions
The purpose of the Decision Review System (DRS) was to decrease umpiring errors in LBW rulings. With DRS, teams can use ball-tracking technology to contest an on-field judgment by predicting whether the ball would have struck the stumps.
- The batsman is out if the ball is seen to strike the stumps.
- According to the “Umpire’s Call” rule, the first ruling is upheld if the ball barely touches the stumps.
- The decision is reversed in favour of the batsman if the ball misses the stumps.
Common Scenarios Where LBW is Given
Let’s examine typical situations when a batter is given out and situations where they are not out to understand LBW better. These instances show how the LBW in cricket rules are used in actual games.
Scenarios Where LBW is Given Out
1. Ball Pitching in Line and Hitting the Stumps
- Example: The middle stump pitches in line with the inswinging ball delivered by a right-arm fast bowler. The ball hits the pad in front of the wickets after the batsman misses his attempt to defend.
- Decision: The decision is to give out because the impact is in line, and the ball is moving toward the stumps.
2. Batsman Not Offering a Shot Outside Off Stump
- Example: A delivery bowled outside the off stump by a left-arm spinner. Without taking a stroke, the batter pads up, and the ball strikes their front pad.
- Decision: The decision was given out because the batsman failed to play the ball, and it was headed for the stumps.
3. The Ball Strikes the Pad First, No Inside Edge
- Example: A leg-spinner bowls a delivery that hits the batsman’s pad before the bat and spins swiftly back into the batsman. The ball was striking the leg stump.
- Decision: Since the ball impacted the pad first and would have struck the stumps, the decision was given out.
Scenarios Where LBW is Not Given Out
1. Ball Pitches Outside Leg Stump
- Example: A fast bowler strikes the batsman’s pad in front of the wickets with an inswinger that pitches outside the leg stump.
- Decision: Not out since the ball pitched outside the leg stump, which is against the LBW rules for an LBW call.
2. Inside Edge Before Hitting the Pad
- Example: When a batter tries to drive, the ball touches the bat before striking the pad.
- Decision: The decision is not out since the ball must strike the pad before LBW is deemed.
3. Ball Missing the Stumps
- Example: Replays reveal that a medium-pacer bowled a delivery above the stumps but struck the batsman’s pad in line with them.
- Decision: The ball would have missed the stumps because of its height; hence, the decision was not out.
4. Umpire’s Call in DRS
- Example: Ball-tracking reveals that the ball hardly clips the stumps when a team reviews an LBW ruling. The ruling is still in effect because the on-field umpire initially declared it not out.
- Decision: Because of the “Umpire’s Call” rule, the on-field decision is upheld, and the cricket player is not out.
