World Rugby has been weighing up the introduction of a centrally-contracted group of referees to oversee international matches, Telegraph Sport can reveal.
The move, which is believed to be under serious consideration by the global governing body, comes in a bid to drive consistency in decision-making across high-profile tournaments such as the Six Nations and the World Cup, as well as one-off tests.
Last weekend brought another high-tackle controversy as Andrew Porter, the Ireland prop, was issued a yellow card by Wayne Barnes for a challenge that left Brodie Retallick, the New Zealand lock, with a broken cheekbone. Porter was cited and faced a hearing on Tuesday but avoided a ban because it was found that the incident "did not meet the red card threshold due to the absorbing nature of the tackle".
Currently, most professional referees around the world are employed by their respective unions. The pay of Premiership officials, for instance, is bank-rolled by the Rugby Football Union and Premiership Rugby.
