Five new laws, on trial this season in many top leagues, will be written into law across the game from July 1.
The 50:22 kick will become a permanent feature of the game, as will the goal-line drop out, both of which have proved extremely popular with fans and players alike this season.
The other laws are more subtle and more welfare/safety-related, with sanctions now being applied to lower limb clearouts in rucks as well as pre-bound pods of players and latching.
“Rugby’s laws are fundamental to its accessibility, appeal and safety,” said World Rugby chairman Sir Bill Beaumont.
“It is our mission to ensure that the laws are the best that they can be for everyone playing the game and the approval of these laws following detailed evaluation and widespread consultation, underscores that commitment.
“I would like to thank every player, coach and medic at every level for participating and providing feedback on this trial – your views are important to us and we will continue to consult with you as we work together to cement rugby as the most progressive sport on player welfare.”
