We were debriefing after a match and the following technical restart questions came up. As part of my U18M Premier Division pregame I instructed the AR’s to not call technical throw-in violations unless the attacking team gained an unfair advantage or was creating a match management problem; I specifically included stepping on the field as a potentially trifling technical violation. During the match I chose a goal kick when an offside player booted the ball over the goaline – after the AR raised his flag, but without my whistle.

1. We know from Advice for Referees on the LOTG that given a choice of IFK for offside infraction and a goal kick or throw-in, to choose the latter in deference to game flow. How about if the offside player kicks the ball over the goal or touch line? Does the obvious game interference take precedence and result in the IFK restart?
2. We know from Advice for Referees on the LOTG that the primary purpose of the throw in is to get the ball quickly in play, and, at competitive levels, technical throw in infractions should be considered trifling. Obviously if the thrower gains an unfair advantage or the infraction may result in a match management problem, the throw in infraction is not trifling and should be called. How about if the thrower has one or both feet completely on the field (no unfair advantage gained nor a match management problem)?

USSF answer (March 23, 2012):
The referee is permitted a certain amount of discretion in enforcing the Laws of the Game, taking into consideration just the sort of things you suggest: game flow, level of skill, effect on match management, etc. However, the referee’s judgments must not be perceived as setting aside the Laws in his or her discretionary acts.

1. Only the referee knows which choice better fits the situation in this particular game. This one clearly comes under the advantage concept as well as the “easier to explain” concept.

2. Infringements of Law 15 are usually trifling (and occasionally doubtful), with the exception at times of being in the wrong location. The infringement needs to be blatant and obvious before the referee calls a “bad” throw-in when it comes to feet. In youth play, even “U18 Premier Division,” the referee should be proactive in dealing with this by stopping the throw-in before it is taken and having the player do it right. Game flow is one thing, but flouting the Law is another. However, having one or both feet fully in the field of play – and well beyond the touchline — is usually more than a trifling infraction.
