Harper says India is holding the world to ransom while a weak International Cricket Council fails to implement required adoption of a Decision Review System wanted by other Test countries.
"If you get one wrong in this format it can’t be rectified. It is a ludicrous situation which makes every situation magnified. It is very frustrating," said Harper, who retired from the ICC elite panel after 95 Tests and 175 one-day internationals in June.
Australian batsmen Mike Hussey and Ed Cowan were given out caught behind in first innings error against India in the test series at the MCG - precisely the errors the DRS was intended to address says Harper.
The Indian Cricket Board - at the behest of senior players - refuses to the use the DRS - complaining the technology isn't fool proof.
It's a lowest common denominator argument says Harper.
He also added "The technology is not 100 per cent accurate but it never will be. It is not perfect but it is a step in the right direction,"
There is a widespread view among Test nations and many in the umpiring fraternity the real reason India opposes the DRS is that the aggressive appealing and intimidation of match officials that win dubious verdicts would be short-circuited by technology.
Harper’s career was finished after challenging India skipper Mahendra Dhoni’s condoning of over the top appealing in the West Indies during the first Test between the West Indies and India at Kingston in June - and public denigration of his performance after the match.
The ICC this year ruled the DRS would be applied for all Test matches only to reverse the edict under pressure from India - an impractical inconsistency allowed by a compromised body says Harper.
"The ICC is doing no controlling and the rest of the world is being held to ransom," said Harper, with Dhoni again guarding the DRS attitude after the first Test in Melbourne.
Former Australian captain Greg Chappell agreed India's powerful position in world cricket played a part in the ICC not demanding uniform adoption of the DRS.
"The fact that they are so powerful they pretty much can make the decisions that fit them best."
