After the India vs Bangladesh match at the 2016 World T20, MS Dhoni, referring to the slow over rate rule, said
I knew that once 20th over started, you can take as much time as possible, you can't get fined for it. I had the luxury of spending a bit of time.
(reported by the Times of India). Does this rule apply to all ICC cricket, or is it something specific to the World T20?
