Fouls bring free kicks; worse brings cards
Tackling and fair charging are allowed — but only frontguard against frontguard. Contact with any other part of the chairs is an offense.
Driving deliberately into an opponent, with or without the ball, at speed or with excessive force, is ramming — an offense. It makes no difference whether they were moving or still, and the same applies when it is careless or reckless.
Deliberately restricting the movement of an opponent’s chair (holding), and deliberately contacting the side or back of their chair to impede them (clipping, a form of holding), are offenses too.
Deliberate handball, using the arms to push, hold or strike (attempts included), spitting, and denying a scoring chance also give the opponents a direct free kick.
If any of these happens inside your own goal area while the ball is in play, it is a penalty kick instead.
A player other than the goalkeeper crossing their own goal line completely (unless pushed by an opponent), a third player entering their own goal area, playing in a dangerous manner, impeding an opponent, deliberately moving or knocking over a goalpost — these give the opponents an indirect free kick.
So does any other offense for which play is stopped to caution or send off a player.
A direct free kick can score straight in. An indirect one must touch another player first.
A spin kick sends the ball farther and faster than driving straight at it. The Laws do not prohibit it.
But for part of the turn the kicker cannot see the ball, or anyone coming towards it. If that happens close to an opponent, it can be judged as playing in a dangerous manner.
Cards are not only for players on court — substitutes and team officials in the technical area receive them too.
If the offender cannot be identified, the senior coach in the technical area takes the sanction.
The referee’s disciplinary authority runs from arriving at the venue until leaving it after the final whistle.
