A free kick in rugby union is usually awarded to a team for a technical offence committed by the opposing side. Free kicks are awarded for technical offences such as playing too many players in a line-out or time wasting at a scrum. A free kick is also awarded for making a mark.
Once awarded a free kick the team must decide how they wish to play it. There are four options.
The team in possession cannot directly score a goal from the free kick itself, nor score a dropped goal until the ball has become dead or an opponent has touched the ball or tackled a ball carrier. This also applies if the team in possession opts for a scrum. Unlike a penalty kick, if the ball goes into touch from a free kick then the kicking team enjoys no special privileges; the line-out is taken by the opposing team rather than the kicking team, and a direct kick to touch from outside the 22-metre area results in this line-out being formed opposite where the ball was kicked, not where it crossed the touch-line. Furthermore, the defending team can attempt to charge the kick as long as they have first retreated 10m. If they prevent the kick from being taken this way, they win a scrum.
