Two of the laws have already been trialed in Super Rugby this year, the goal-line drop out, which has been seen in Super Rugby Aotearoa and trans-Tasman - and the 50m line to 22m line kick, which was used in Super Rugby AU.
World Rugby believes both have the potential to increase space and decrease defensive line speed.
Three trials focus specifically on reducing injury risk at the breakdown.
The first is the introduction of sanctioning of clear-outs which target the lower limbs. The second will outlaw the practice of multi-player (three or more) pre-bound pods. The third area will tighten the definition of what is permissible in the practice of one-player latching.
After a global trial period of one year, laws that are deemed successful in meeting the objective of increasing safety while enhancing the spectacle will be tabled for World Rugby to determine whether they are adopted into law at its May 2022 meeting, a full year ahead of Rugby World Cup 2023 in France.
A breakdown of the new laws:
50:22: This law trial is intended to create space via a tactical choice for players to drop out of the defensive line in order to prevent their opponents from kicking for touch, reducing impact of defensive line speed - operational in Super Rugby AU
Goal-line drop out: This law trial is intended to reduce the number of scrums, reward good defence, encourage counter-attacking and increase the rate of ball in play - operational in Super Rugby AU, Super Rugby Aotearoa, Super Rugby Trans-Tasman and the Rainbow Cup
Welfare-focused breakdown law amendments approved for global trial
Pre-bound pods of players: Outlawing the practice of pods of three or more players being pre-bound prior to receiving the ball - the sanction will be a penalty kick
Sanctioning the lower limb clear-out: Penalising players who target/drop their weight onto the lower limbs of a tackler - the sanction will be a penalty kick
Tightening law relating to latching: One-player latch to be permitted, but this player has the same responsibilities as a first arriving player (ie. must stay on feet, enter through gate and not fall to floor) - the sanction will be a penalty kick
