Obstruction is when a player is within 3 feet of the person with the ball when marking the ball. The ball stays with the opposition and you have to stand next to the player for that one pass.
This is called obstruction of jusice or resisting arrest by giving false information.
this is not a foul so just play on ---- If the ball is within playing distance of the player, then the tactic of "shielding" or "sheparding" the ball, as it's sometimes called, is perfectly legal. If the player is blocking an opponent when the ball is miles away, an indirect free-kick is awarded for obstruction.
It is called Airway obstruction / Tracheal obstruction
An indirect free kick may be awarded in the penalty area. It is not promoted to a penalty kick. If it is in the goal area, the kick location must be moved away from the goal line to the top of the goal area (6 yards out).
I believe if either one is directly in the baseline, that is indeed interference (the runner is awarded the base). Obstruction can only be called if the runner makes contact with one of the fielders. If he zig-zags around them without drawing contact then he can be called out for going out of the baseline.
This penalty is called "Clipping".
The so-called "Back Pass" rule means that the goalkeeper cannot handle the ball, even within his own penalty area, if it was deliberately kicked to him by a teammate. If the goalkeeper violates this rule, an indirect free kick is awarded to the attacking team at the point where the goalkeeper handled the ball. Note that a penalty kick can never be awarded for a goalkeeper's handling.
Using the stick or body to prevent another player from playing the ball in any way is called obstruction, and can have various repercussions in a game. If the stick is used to prevent a player from tackling, the normal penalty is simply a free hit. However if it is done inside the circle by a defender an umpire is likely to call a penalty (or short) corner. This is seen as a minor offence and will not usually result in a card being awarded. If the stick was used aggressively in the obstruction (e.g. hacking or interfering as opposed to simply blocking), a more severe penalty may be given; a PC within the 23-metre area or a penalty stroke within the circle, if done by a defender, and a green card is possible. This is a more serious offence that most umpires will penalise harshly, as it is dangerous and very unsportmanlike conduct. If the body is used then there can be a range of reactions. For example shadow obstruction (one player stopping an opponent from tackling a teammate) will not be penalised too hard as it is usually not deliberate, but when it is the umpire will give a more serious penalty as well as a warning. When the body is used aggressively against another player (such as shoulder barging or elbowing) an umpire should be very severe on this as it is a very serious offence and can result in injury or start a fight. An offending player is likely to be green or yellow carded immediately, and a free hit should be given normally. If a defender were to do this inside the 23m area, a PC will probably be awarded, and within the circle is almost assuredly a PS.
