Law 17 - Corner-kick

When the whole of the ball passes over the goal-line, excluding the portion between the goal-posts, either in the air or on the ground, having last been played by one of the defending team, a member of the attacking team shall take a corner-kick, i.e. the whole of the ball shall be placed within the quarter circle at the nearest corner-flagpost, which must not be moved, and it shall be kicked from that position. A goal may be scored direct from such a kick. Players of the team opposing that of the player taking the corner-kick shall not approach within 10 yards of the ball until it is in play, i.e. it has traveled the distance of its own circumference, nor shall the kicker play the ball a second time until it has been touched or played by another player.

Punishment:

If the player who takes the kick plays the ball a second time before it has been touched or played by another player, the referee shall award an IFK to the opposing team, to be taken from the place where the infringement occurred, subject to the overriding conditions imposed in Law 13.
For any other infringement the kick shall be retaken.
