IAIN AD Mann makes a familiarly superficial case for instant television reviews of debatable decisions in football. (Letters, September 27). A number of years ago, when the SFA indicated their willingness to pilot goal-line technology, in response to my inquiry as to how the game could be restarted in a manner fair to the attacking side should replays show that the ball had not crossed the line, John Fleming, the referees'

Supremo, replied that a bounce-up on the six-yard line would follow, a clear indication of the shortcomings of judgment by television.

Apart from the technical differences between football and the sports he cites as desirable examples, Mr Mann fails to address the fact that every refereeing decision in a football match has a direct bearing on the eventual result. For example, should a goal-kick be wrongly awarded at one end and the outcome of the ensuing passage of play is a goal at the other, logic would then dictate that every questionable decision by the referee should be subject to immediate review, a nonsensical proposition for a game in which continuity is a paramount feature.

An extension of off-the-pitch adjudication will only serve to further undermine the authority of referees, who are obliged to make speedy and often split-second decisions on the spot, nor is it guaranteed to eliminate controversy, as the endless debates about diving or not diving in the penalty-area readily prove. The on-the-park unpredictability of football has sustained its attraction down the years and if this is eroded by the increased involvement of technology, its appeal will diminish accordingly.
