The DRS came under arguably the strongest scrutiny since it was adopted by the International Cricket Council after some critics argued its application at Trent Bridge last week created more problems than it solved.
South African official Marais Erasmus, third umpire in that Test and standing on-field in the follow-up at Lord's this week, made a hotly disputed call to overturn Aleem Dar's not out lbw verdict against Jonathan Trott, despite not having the full battery of replays available.
A number of other marginal calls were also debated, but Australia had no reviews left when Stuart Broad's clear edge to slip went undetected.
But the MCC cricket committee, an independent group of eminent former players and officials who meet twice yearly to debate and advise on the key issues affecting the game, remains in clear support of the referral system.
It believes the problems experienced at Trent Bridge were down to basic human error - a factor that cannot be eradicated but has been lessened by DRS.
A statement released by the committee following a two-day meeting at Lord's this week read: "It was a unanimous view of all members of the World Cricket Committee present at its meeting that the Decision Review System works, and undoubtedly helps the umpires to bring about more correct decisions on the field.
"Incidents at the recent England v Australia Test match at Trent Bridge were discussed. The committee was unanimous in its opinion that it was the poor implementation of DRS that led to the controversies, rather than the system itself.
"Human error will always play a part in the game for both players and umpires but the DRS is successful in limiting this.
"With the DRS, more correct decisions are being made (generally DRS improves correct decision making by about five percentage points in Test cricket) and so the committee strongly reiterates its desire to see the universal implementation of the system in international cricket matches.
"The DRS is not perfect, but it improves decision making and adds to the spectator experience, which is good for the game.
"A further benefit from universal use would be the ownership of the whole process by ICC rather than by television companies."
