The 2022 FIFA World Cup has highlighted challenges stemming from recent changes to the Laws of the Game, particularly the implementation of the revised "mistaken identity" rule and other officiating protocols. These adjustments, introduced by the International Football Association Board (Ifab) earlier this year, have generated debate over consistency and clarity in refereeing decisions during the tournament.

The "mistaken identity" clause, which now covers situations where a player is wrongly cautioned or sent off for an offense committed by another player from either team, was applied notably in Paraguay’s group stage match against the United States. In that game, after Paraguay’s Miguel Almirón was seen to have simulated a foul, video review led to the rescinding of a yellow card initially given to U.S. player Tim Ream, and Almirón himself received a booking for simulation. The rule’s significance became even more apparent in the quarter-finals, when Switzerland’s Breel Embolo was issued a yellow card that was first attributed to Argentina’s Leandro Paredes. The reversal left Embolo with a second caution, resulting in his expulsion and leaving Switzerland a player down in a late-stage match they eventually lost in extra time.

This rule revision was part of a broader package endorsed by Ifab following their annual meeting in February and a subsequent special session in April, which also introduced a new sending-off offense for players who cover their mouths when communicating provocatively with opponents. Almirón was subsequently sent off for this offense in Paraguay’s second game of the tournament.

Officials have also grappled with other recent adjustments, such as the requirement for substituted players to leave the field within 10 seconds of the substitution signal unless hindered by safety or injury issues. This has introduced scenarios where players’ on-field behavior and injury claims have complicated referees’ judgments about whether to allow play to continue or pause for treatment.

In several instances, refereeing decisions appeared inconsistent with established rules. For example, Egypt’s Mostafa Ziko was not penalized with the mandatory yellow card after removing his shirt during a goal celebration, an infraction clearly outlined in the laws. Similarly, protocols for halting matches over homophobic chants by spectators were not enforced, despite the recurrence of such incidents and previous sanctions against the Mexican team.

Technology’s role in officiating has drawn mixed reactions, particularly regarding Video Assistant Referee (VAR) interventions. A contentious decision arose in Croatia’s match against Portugal, where a late goal was disallowed because the ball reportedly touched a player’s hair, positioning a teammate in an offside position by a margin measured in mere centimeters. While VAR aims to enhance accuracy, such fine margins have reignited debate over the balance between technological precision and the spirit of the game.

Some calls, such as a foul on the United States’ Folarin Balogun, remain subjects of ongoing discussion, underscoring that officiating often depends on human judgment as much as on written laws and video evidence.

Critics argue that the timing and volume of law changes implemented by Ifab and FIFA—especially their introduction during the World Cup—have contributed to confusion among players, officials, and fans alike. The frequent revisions to complex rules like handball have compounded the issue, occasionally leaving interpretations inconsistent and contentious.

These developments illustrate the challenges FIFA faces in maintaining rule clarity and referee consistency on football’s biggest stage, raising questions about whether significant law changes should be trialed before being adopted in high-profile tournaments watched by millions around the world.
