The first criterion can be phrased as ""all" of the ball must cross "all" of the line" and is of particular importance in decisions regarding goals. The question of whether the ball has crossed the line has often caused controversy in high-profile matches, such as in the example of Geoff Hurst's goal in the 1966 World Cup Final, that put England 3-2 up over West Germany in extra time. The Law specifically notes that the ball remains in play if it rebounds off a goal frame or corner flag onto the field, or in any case of the ball touching a match official that is not mentioned above.
