5 runs and a new ball! if you could buy a new ball at any point in a match for 5 runs, bet teams would! Although no evidence of ball tampering has been found, and Pakistan felt aggreived, they should have just lodged a complaint after the match, or at the end of the day, the rules are clear about being late or not turning up for tea, and in that instance the Umpires acted quite correctly, the Pakistnis only have them selves to blame AFAIC.
