In one incident :
Pakistan captain Babar was found guilty of 'illegal fielding' after he handled a ball using wicket-keeping gloves
It seems that the wicket-keep intentionally dropped his gloves to better hold the ball and throw it towards the stumps. The fielder, just having mindless fun, decided to wear the gloves.
There are more incidents like that, but restricting to only this Incident.
According to MCC :
28.2 Fielding the ball
28.2.1 A fielder may field the ball with ....
.... have fielded the ball illegally if
22.214.171.124 uses anything other than part of his/her person to field the ball.
126.96.36.199 discards a piece of clothing, equipment or any other object which subsequently makes contact with the ball.
By 188.8.131.52, Babar (who used some equipment) is at fault for "fielding illegally".
By 184.108.40.206, the wicket-keeper (who discarded the equipment, which made contact with the ball) is at fault for "fielding illegally".
Of course, Babar is already at fault for wearing the gloves, but is he also at fault for "fielding illegally" ?
Or is it the wicket-keeper who is at fault for "fielding illegally" ?
It is curiosity to know this, but it may have implications on who pays the fine and whose record shows the fault for "fielding illegally".
