The reason why Chauhan interfered in the pitch is simple. ICC has appointed a pitch monitoring committee to overlook the matters involving interference of home side captains applying pressure to make pitches suited to home side.
Anil Kumble might have had a look at the pitch and knowing he cannot interfere in the matter directly, might have spoken to the Management or Administrators of Delhi Cricket Organization and thats how chauhan interfered and got the grass cut off.
Same old story, make dead batting tracks or make dusty bowls.
