what exactly is the rule for LBW? y cant any1 appeal to the 3rd umpire for this?

Answer 1

Coz the eumpire at the spot can well judghe the behavior of the ball, whether being swingin or away, bouncy or down.
so on the camera, we cannt check the exact results.

Answer 2

1> The rule is that the ball should hit the bat first not the pad.
2> The second rule is that pad should be in line of the stumps
3> It should not be over the knee rod

Answer 3

In the sport of cricket, leg before wicket (lbw) is one of the ways in which a batsman can be dismissed. An umpire will rule a batsman out lbw under a complex series of circumstances that primarily include the ball hitting the batsman's body when it would otherwise have continued to hit the wicket. The lbw rule is designed to prevent a batsman protecting his wicket against being bowled, with his body rather than his bat.

Despite the word leg in leg before wicket, the rule applies if the ball hits the batsman on any part of his body, except for the glove of a hand in contact with the bat (which is considered part of the bat).

Conditions for LBW
The conditions for a batsman to be given out lbw are:

The ball must be legal
The ball must not be a no ball.
The ball must not pitch (bounce) on the leg side
The ball must either (a) pitch in line between wicket and wicket or on the off side of the wicket, or (b) not pitch at all before reaching the batsman. Therefore, any ball pitching on the leg side of the wicket should not result in the loss of a wicket by lbw. To determine the relevant 'pitching zone', an imaginary line is drawn parallel to the long axis of the pitch from the leg stump.
The ball must miss the bat
If the first experience the batsman has of the ball is hitting it with his bat, he should not be out lbw.
The ball must intercept a part of the batsman's person
If the ball hits any part of the body, it is a potential candidate for lbw (ie. it need not hit the leg). The one exception is a hand or gloved hand in contact with the bat, which is considered part of the bat.
The ball must impact in line
The ball must impact the batsman in the region directly between the two wickets. An important exception is that, if the impact is outside the off stump, the batsman can be out lbw if he does not make a genuine attempt to play the ball (that is, if he does not "play a stroke"). If the impact is between wicket and wicket, the playing of a stroke is irrelevant.
The ball must be at the correct height
If the ball is too high and would have gone over the stumps, then it is not out.
The ball must have been going to hit the wicket
If the ball's trajectory suggests that it would have missed the wicket had the batsman not been present, then he should not be out lbw.
There are three rules for the interpretation of these conditions: only the first interception of the ball by the body is considered; whether the ball would have pitched after interception is irrelevant; and the identities of the 'off side' and 'leg side' are to be determined by reference to the batsman's stance when the ball is delivered.

The exception to the fifth condition (ball must impact in line) involves the judgment of the umpire on whether the batsman has attempted to play a shot at the ball. It is designed to prevent batsmen from merely kicking the ball away outside the off stump, which provides no chance of giving up a catch off the bat. A common defensive tactic against spin bowlers is to use the leg pad to defend against balls on the off side, but the lbw rule means they must either have the bat placed near the pad, thus providing a chance for edging a catch to the slip fielders, or risk being ruled out lbw. Some observers, such as Richie Benaud, have suggested that the lbw law be changed so that a batsman can be out if the ball pitches just outside the leg stump, thereby assisting legspinners and preventing negative pad-play.

The lbw rule is always judged by the umpire at the bowler's end. If the fielding team believes a batsman may be out lbw, they must appeal to that umpire for a decision.

All the lbw conditions must be assessed for the delivery, which takes around half a second to reach the batsman. As in other aspects of the rules, the batsman is always given the benefit of any doubt so, if an umpire is unsure, the appeal will be turned down. An example of this is if the batsman takes a step forward before the ball hits the batsman's leg. The ball might well have gone on to hit the wicket, but it is very difficult for the umpire to be certain of this, as the ball would have been 1.5-2 metres in front of the wicket as it hit the batsman's leg.


With the benefit of television replays it is common to show whether or not all of the lbw conditions were satisfied, and thus some people complain that an umpire wrongly allowed a batsman to continue or wrongly gave him out. However since the umpire should be certain that a batsman is out in order to give him out, and he has no benefit of television replay, the umpire's decision is usually appropriate. Most players and commentators acknowledge this and criticism of umpires is minimal.

The lbw decision is arguably the hardest the umpires have to make, and can be a source for commentary and controversy amongst the spectators. In recent years, with the increasing amounts of pressure and money at stake in cricket, several people have been campaigning for a larger role of cameras and simulation technology such as Hawk-Eye to aid the umpire in the uncertain cases. For the moment, lbw remains a decision that falls solely under the purview of the on-field umpire. Change is in the air, however: in September 2005, the ICC authorized a trial run of the use by umpires of television replays to aid in making the call (see external link below).

It is worth noting that a batsman can be out lbw if the ball hits the pad first and then goes on to hit the bat (a so-called pad-bat), but not in the case where the batsman hits the ball with the bat but the ball then goes on to hit his pad (a bat-pad). However, in the latter case, a batsman runs the risk of being out caught, as the ball may ricochet off the pad at a relatively low speed for a close fielder (such as silly mid on) to catch.

Lbw (N)
lbw (N) was a term used to describe an alteration in the law of leg before wicket that was made by MCC on November 21, 1934. It came into force in 1935 in England but was opposed by high-level authorities in Australia where it did not come into force until the 1936/1937 season, even though it was tried in club games in Australia during the 1935/1936 season.

The alteration consisted of permitting a ball pitched outside off stump to produce an lbw wicket if the batsman stopped it with any part of his person in a straight line between wicket and wicket. Previously, only a ball pitched in a straight line between the bowler's and the striker's wickets could yield an lbw dismissal.

The term "lbw (N)" referred to the fact that from 1935 to 1937, wickets under the new leg before wicket rule were distinguished in scoredcards published by Wisden from those under the pre-1935 rule.

It shouldn't be appealed as it has to be taken by the on-field umpire. Now ICC is thinking to introduce this plan.

Hope you can understand this.

Answer 4

this is the last dimisal left for the onfield umpire that dont involve 3rd umpire....some it s alos
involve them
