Despite strong resentment from Pakistan, Sri Lanka and South Africa, the controversial proposal was passed at the Executive Board meeting after gaining the support of eight of the ICC's 10 full members.
"After rounds of discussions over the last three weeks, the proposals were approved without any objection," BCCI secretary Sanjay Patel told ESPNcricinfo.
"Two members abstained from voting since they felt it wouldn't be prudent for them to take a call without the go-ahead of their respective boards.
The controversial proposal had faced opposition from Pakistan, Sri Lanka and South Africa but while the first two countries stayed away from the meeting today, the latter had a change of heart after Cricket South Africa president Chris Nenzani had a long meeting with BCCI president N Srinivasan.
CSA is the first Full Member to publicly describe the proposals "fundamentally flawed" but they opted to vote in favour of the changes today.
