India will not embrace the Decision Review System until they believe the technology involved is "foolproof".
The Board of Control for Cricket in India has opposed the DRS since featuring in the first Test series to implement the system against Sri Lanka five years ago.
Their stance has been strengthened by the number of controversies over the first three Ashes Tests this summer, and BCCI interim president Jagmohan Dalmiya believes the DRS and the Duckworth-Lewis adjusted scoring format both need an overhaul.
"We will accept DRS when technology is foolproof," Dalmiya is quoted as saying in The Indian Express newspaper. "There's nothing in between."
"Let them come up with a system which is 100 per cent correct. 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.
"I'm still trying to figure out how a team total is increased on the basis of projection. The whole process is very complicated and confusing.
"And rather than solving the riddle, DRS creates more confusion in its present form," added Dalmiya, who insisted his apprehension was shared by other Test-playing nations at the ICC annual conference earlier this year.
"Before going to the ICC meeting I was a bit 'iffy' as I was told by some quarters that India would be completely isolated on the DRS issue," he said.
"But after I was done with my presentation on that day, there was not a single voice of protest."
