Interference in kickball is when a player, spectator, referee, or object interferes with the game either deliberatly or bi-accident. There are lots of interference rules in kickball such as referee's interference, spectator's interference, baserunner's interference, kicker's interference, and fielder's interference.
Kicker's interference in kickball is a rule that states the kicker cannot interfere with a fielder's ability to field the kickball. For example, if a kicker kicks the ball a second time when advancing to first base as the kicker-runner he will be called out by the Head Referee.
Defensive interference in kickball is called on any fielder who impedes the movement of a baserunner on the field. If a fielder is called for interference, the previous play is nullified and must be replayed.
Baserunner's interference in kickball is a penalty where a baserunner interferes with a fielder's ability to field the ball.
Offensive interference in kickball is any type of interference committed by the offense, usually referring to kicker's interference or baserunner's interference.
Referee's interference in kickball is a rule that states a referee cannot interfere while the ball is in play such as impeding the movement of a baserunner or fielder. In the case of referee interference, the previous play is nullified and batter must return to the kicker's box.
Spectator interference in kickball is a penalty called on any fan or spectator that interferes in the game. In the case of spectator interference the previous play is discounted and must be repeated.
