A player delivers a throw-in with both hands, yet the referee awards it to the opponents. The problem may have been below the waist. The position of the feet matters at the moment the ball is delivered.
IFAB Law 15 requires the thrower to face the field, have part of each foot on the touchline or on the ground outside it, and throw with both hands from behind and over the head. The delivery is made from where the ball left the field.
Freeze the right moment
On a replay, stop at release. A foot may move after the ball has gone, so a later still image can misrepresent the action that needs judging. Conversely, a foot planted during the run-up does not settle whether it remained correctly positioned for delivery.
The wording also explains why a foot touching the line is not automatically an offence. Look for the required part of each foot in contact on or behind that boundary, rather than assuming the entire shoe must be outside the field.
Keep the other conditions in view
Both hands being on the ball does not make every delivery lawful. Watch the movement from behind and over the head too. A poor-looking throw and an incorrect throw are not necessarily identical; assess the actual requirements rather than style alone.
The ball is in play when it enters the field. The thrower cannot touch it again before another player does, and the law contains further requirements for opponents and restarts. A goal cannot be scored directly from a throw-in.
For a viewing exercise, follow two ordinary throws before analysing a disputed one. Note the release, foot contact and where the ball enters the field. That sequence gives you more useful evidence than a crowd reaction or a cropped photograph showing only the player’s arms.
