Ponting repeats history at SCG

I think ICC should add some new rules to cricket after this:

McDonald to Kallis, OUT, oh well held, McDonald .. or not? Pitches it up down the stumps, Kallis goes back and starts to turn it to the on side, but the ball takes a leading edge and balloons back up in the air towards the bowler, who flings himself to his right in his follow through and looks like he's taken a stunner ... his team-mates converge but Kallis asks for confirmation, and McDonald admits he's not sure. To the naked eye it looked like he took it, Ponting sticks up a finger even before the umpires are consulted, and after numerous analysis Kallis is adjudged out. Thats a very, very tough call. One angle indicates he took it, the straight view says something else. I'm not convinced he took it.

Last year, during 2nd Test match between India and Australia, Ganguly was given OUT by Ponting:

Lee to Ganguly, OUT, huge appeals as Clarke is adamant he caught the ball low in front of him at second slip. Ganguly stands his ground, disgusted, and finally walks off. Replays suggest there is some doubt about whether it carried or not. The zoom in replays have showed that the ball may have bounced before Clarke took it. Close call but there was doubt. Benson seemed to ask someone and then gave it out, replays show Ponting indicating that the catch was taken. Ganguly, after he nicked that stood long and hard, not convinced that Clarke had caught it, the Australians had no doubt it was out. Replays showing that Clarke may have grounded the ball as he rolled over after taking the catch.
