This principle downgrades X simply because it isn't perfect. It says in effect " Either the policy is perfect. else we must reject it"

Some examples

DRS and BCCI

Lets take a look at the DRS (Decision Review System in Cricket). The system offers 90 t0 95% accuracy. However the BCCI is not in favor of the system because it is not 100% Correct. This is a debatable stance. Those who believe 90 to 95% accuracy is adequate, would say that the BCCI is a victim/perpetrator of the Line Drawing Fallacy - unless it is 100% accurate, it will not accept the DRS
