The FIFA decision described in the article is without precedent, whereas the examples of situations in football where a ball has been well over the line and not been called a 'goal' are multiple, and the reverse ie a goal been given when the ball was definitely over the line, happened in extra time in a World Cup Final. That made the score 3-2. The final score was 4-2, and even thought everyone knows the goal wasn't a goal, the score of that game remains 4-2.
