I don’t have a timetable of how the handball law/ interpretations have changed over recent years.
But until relatively recently the law simply said something along the lines of….
…. If in the opinion of the referee, a player, other than a goalkeeper in his penalty area, deliberately plays the ball with his hand or arm, a handball offence has occurred.
No mention of where the arm extends to exactly. No mention of what position the arm was in or where the ball was heading. Deliberate was handball. Accidental was not.
Simpler days.
