Goal Line Technology – Necessary or Unfair

Introduction
Soccer is undoubtedly one of the most popular sports worldwide. From regional club championship to the world cup, each soccer event is watched with tremendous enthusiasm by people all over the world. As soon as the match starts and until it ends, soccer fascinates its viewers by passes, shots, tackles, free kicks and penalties. Of course, in the course of all this, there are also goals. Whenever the ball enters the goal, it is a moment of triumph. For a moment everyone watching is left awe-struck until the realization sets in, and then there is much rejoices. However, what if, the referee blows his whistle and says the goal was invalid. Moreover, what if, a ball that was seemingly deflected by the goalkeeper is counted as a goal. Obviously, this would have its repercussions, but this is the idea pronounced in the goal line technology. Two IFA-approved methods of implementing goal line so far exist – Hawk-Eye and GoalRef. To start a discussion about goal line, it should be understood how each of these technique works. Hawk-Eye, the more favored technique, is one which is already being utilized in the sports of cricket and tennis. The technique makes use of six high-speed cameras linked to fast-processing computers. These cameras track every movement of the soccer ball as it moves through the field, and the computers calculate the relative position on the ball based on metrics provided by the cameras. When the ball would pass the goal line, the computers would be able to determine this and the possibility of a goal would have to be judged. The technique is more favored because of its potential to produce excellent 3D replays of what took place, and also because it can be used on-field for other purposes than just goal line. For instance, the curves a specific free kick shot took, or even if an offside actually occurred or not could be realized with the help of Hawk-Eye. However, this technique would be quite expensive to implement. High-speed cameras aside, every soccer stadium would also need to implement black netting which is also a prerequisite of Hawk-Eye. On the other hand, GoalRef is a much more economical option. GoalRef makes use of a low-powered magnetic field around the posts and a magnetic probe in the ball. As soon as the low-powered magnetic field is found to be penetrated by the magnetic probe completely, the referee is notified through a hand-held device that a goal has occurred and the referee can announce it almost immediately. The relative simplicity of the design and technology being used also makes it easier for ball manufacturers to add probes into the balls. However, compared to the multiplicity of uses that Hawk-Eye provides, GoalRef is a bit lacking. Taking into consideration these factors, the discussion in this paper would focus on both the technologies rather than one. (EuroSport, 2012) Goal line technology has been debated from both ends of the argument by various soccer overseeing bodies – such as FIFA and UEFA – for much of the last decade. However, to-date, no compromise has been reached. There are two reasons for which goal line technology has been proposed. Firstly, according to international soccer rules, a goal is scored if a ball completely passes the goal line. However, the on-field referee cannot judge this as he has to stay away from the goal during times of attack and defense. In the recent past, this inability of referees has resulted in many wrong judgments. Secondly, the use of decision-aid technology is being aggressively integrated in various other sports. With every passing year, popular sports across the world are introducing decision-aid technology to either aid existing referees or even replace them. As the pressure on soccer associations mount, it has become necessary to realize whether goal line technology is good or bad for the game. This paper would argue that goal line technology is essential as it provides...
