LBW in Cricket Explained: The Complete Law and How Decisions Are Made
Understand the LBW law in cricket — all five conditions that must be met, how umpires decide, DRS ball-tracking, and common misconceptions explained clearly.
Leg Before Wicket (LBW) is the most complex dismissal in cricket and the source of more controversy than almost any other law. Unlike a caught dismissal — which is immediately obvious — LBW requires an umpire to evaluate five separate conditions simultaneously, often in less than a second.
The Five LBW Conditions
For an LBW decision to be correct, all of the following conditions must be satisfied. If any one fails, the batsman is not out.
- The ball must not be a wide or no-ball
- The ball must pitch in line with the stumps OR on the off side of the stumps (not outside leg stump)
- The ball must hit the batsman's body (pad, leg, or any part) before hitting the bat
- The point of impact must be in line between wicket and wicket (or outside off stump, in certain circumstances)
- The ball must be going on to hit the stumps — umpire's projection
The Crucial 'Outside Leg Stump' Rule
If the ball pitches outside leg stump, it can NEVER be LBW — regardless of where it hits the batsman or where it would have gone. This protects batsmen who play sweep shots or use their pad to keep out deliveries that spin back sharply. It is the single most misunderstood aspect of LBW.
The 'Impact Outside Off Stump' Condition
If the ball strikes the batsman's pad outside the off stump (not in line with the stumps), LBW can still be given — but only if the batsman made no genuine attempt to play the ball with the bat. If the batsman offered a shot and missed, they cannot be given out LBW for a ball hitting outside off stump.
| Impact Location | Batsman Played a Shot? | LBW Possible? |
|---|---|---|
| In line with stumps | Yes or No | Yes (if all other conditions met) |
| Outside off stump | No | Yes (if ball would hit stumps) |
| Outside off stump | Yes (missed) | No — not out |
| Outside leg stump | Yes or No | Never |
DRS and Ball-Tracking Technology
The Decision Review System uses Hawk-Eye ball-tracking technology to predict the projected path of the ball after impact. Ball-tracking shows where the ball would have gone after it hit the pad — a 3D projection based on the ball's speed, spin, and seam angle at the point of contact.
DRS Umpire's Call and the Margin of Error
Hawk-Eye acknowledges its own margin of error: approximately 2.5mm at the point of impact. For this reason, DRS uses the concept of 'Umpire's Call.' If more than half the ball is hitting the stumps on projection, the on-field decision is overturned. If the ball is clipping the stumps — hitting with less than half the ball — the on-field decision (whether Out or Not Out) stands.
Common LBW Misconceptions
- Myth: 'You can't be out LBW playing a sweep shot.' False — you can be LBW sweeping if the ball would have hit the stumps and pitched in line
- Myth: 'The ball must hit the pad.' False — any part of the body can result in LBW, including arms, hands (if holding bat), or chest
- Myth: 'You're safe if the ball hits outside off stump.' Partly false — if you don't play a shot, you can be out even if hit outside off
- Myth: 'LBW only applies to the front leg.' False — both legs can be struck, and impact from either leg can be LBW
- Myth: 'The ball hitting the bat first means Not Out.' True only if bat touches ball before pad — if pad first, then bat, LBW is still possible
Reviewing an LBW Decision with DRS
When a batsman or captain reviews an LBW that was given Out, DRS checks: (1) pitch location — did it pitch in line or outside leg? (2) Impact location — did it hit in line or outside off? (3) Was the batsman playing a shot? (4) Projected path — would it have hit the stumps? Each check is sequential, and a failure at any stage overturns the decision.
Frequently asked questions
Can you be given out LBW if the ball hits your hand?
Yes — if the hand is holding the bat handle and the ball strikes the glove (below the wrist), it is considered part of the bat, not the body, so LBW does not apply. But if the ball hits the bare arm or any other part of the body first, LBW conditions can apply.
What is 'Umpire's Call' in cricket DRS?
Umpire's Call is the term used when ball-tracking shows the ball is clipping the stumps — within the margin of error. In this scenario, the on-field decision (whether Out or Not Out) is retained. The reviewing team keeps their DRS review if the decision is upheld via Umpire's Call.
Can a batsman be LBW on a no-ball?
No. The first condition of LBW is that the delivery must be a legal delivery. A batsman cannot be dismissed in any way off a no-ball except by run-out, hit the ball twice, handled the ball, or obstructing the field.
Why can't a batsman be LBW if the ball pitches outside leg stump?
The law was designed to protect batsmen from being dismissed on deliveries that turned sharply or seamed back onto the pads from outside leg stump — a delivery the batsman could not reasonably have played with the bat. It protects leg-side play and prevents bowlers from bowling purely at the pads on the leg side.
