1) The ball is played back deliberately by a teammate to the keeper in the PA, must (as the law states) the keeper touch the ball with the HANDS or would a touch with the wrist, arm or outside shoulder similarly qualify as an infraction?

(2) In playing the ball back deliberately to the keeper, a teammate plays with ball with the shin (leg below the knee and above the foot). Should this lead to an infraction if the keeper touches the ball with the hands in the PA?

(3) A defender grabs the shirt of an attacker 10 yards outside the PA and continues the hold until the attacker and defender enter the PA. At this point the hold is released. The referee uses advantage, but stops play for the foul when the attacker staggers and falls. What is the proper restart?

Answer (March 18, 2014):
(1) The referee must first judge the position of the hand/arm. The hand is defined as extending from the tip of the finger to the outside of the shoulder. If the position is abnormal, then the foul must be punished; however, if the ball has taken a truly bad bounce, the referee will certainly exercise common sense and could let it go.

(2) No, this is not an infraction. The ‘keeper is not allowed to use his or her hands to play the ball deliberately kicked to him or her. A kicked ball may be in contact with the shin, but that contact MUST also include the foot to be truly a kick. Kicking does not include balls played solely (no pun intended) with the shin unless part of the foot itself is also involved..

(3) Under Law 12, as stated in the Interpretation of the Laws of the Game and Guidelines for Referees in the back of the Laws, we find:
Holding an opponent
If a defender starts holding an attacker outside the penalty area and continues holding him inside the penalty area, the referee must award a penalty kick.

NOTE: This continuation is an established principle of the Law and applies only to holding, not to any other foul.
