The back pass rule refers to the restriction on the goalkeeper from using their hands to handle the ball after it has been deliberately kicked to them by a teammate. This rule was introduced in 1992 to prevent time-wasting tactics by teams. However, there are several synonymous terms used interchangeably for the back pass rule. These include 'the passback rule', 'the goalkeeper rule', 'the playing back rule', 'the backpass law', 'the goalie rule', and 'the pass-back law'. These terms all refer to the same rule that has significantly impacted gameplay and remains a vital aspect of football regulations today.
