its still in rule 12 that impeding without contact is an indirect free kick
in what circumstances is that possible then
in the aid section is this
IFAB Laws of the Game 2016-17
An indirect free kick is awarded if a player
- impedes the progress of an opponent without any contact being made
IMPEDING THE PROGRESS OF AN OPPONENT WITHOUT CONTACT
Impeding the progress of an opponent means moving into the opponent’s path to obstruct, block, slow down or force a change of direction when the ball is not within playing distance of either player.
All players have a right to their position on the field of play; being in the way of an opponent is not the same as moving into the way of an opponent.
A player may shield the ball by taking a position between an opponent and the ball if the ball is within playing distance and the opponent is not held off with the arms or body. If the ball is within playing distance, the player may be fairly charged by an opponent.
