India will accept the Decision Review System only when it becomes "foolproof", India's top cricket administrator says.
India was part of the first-ever Test series featuring the DRS in Sri Lanka five years ago but has opposed the system of referrals to the television umpire.
Jagmohan Dalmiya, who's the president of Board of Control for Cricket in India, says he's not convinced about its accuracy.
"We will accept DRS when technology is foolproof," Dalmiya told The Indian Express newspaper. "There's nothing in between."
Dalmiya said he was not sure when the system would become perfect.
"Let them come up with a system which is 100 per cent correct," he said.
"They couldn't fix the Duckworth-Lewis problem in 15 years, what guarantee do we have about an error-free DRS?
"The Duckworth-Lewis method is beyond most of the players and administrators, let alone the common fans."
The Duckworth-Lewis system revises targets in case of rain interruptions during limited-overs games.
"I'm still trying to figure out how a team total is increased on the basis of projection," he said.
"The whole process is very complicated and confusing. And rather than solving the riddle, DRS creates more confusion in its present form."
And Dalmiya, a former chairman of the International Cricket Council, says India was not isolated on DRS at the ICC annual conference this year.
The DRS has been under scrutiny with some contentious decisions during the past few seasons, including in the ongoing Ashes test series in England.
