At a meeting in September 2018, World Rugby’s Rugby Committee determined that certain aspects of foul play law needed to be reinforced by match officials:
High Tackles and Neck contact - Law 9.13 & 9.20
In both the tackle and cleanout as per current law:
A player must not make contact with an opponent above the line of the shoulders.
Every time the head or the neck is deliberately grabbed or choked, the offending player runs the risk of receiving a yellow or red card
Head contact and cleanouts around the neck must be penalised.
Match officials should work together to ensure that foul play is strictly penalised and that player welfare is paramount
