Law 4 of the Laws of the Game (and its corollary Regulation 12 of the Regulations Relating to the Game) permit and prohibit certain equipment in order to protect Player Welfare and the fundamental essence of the game of rugby union. The Regulations flow from the Laws which are the central document which set out the identifying features, skills, equipment, values and Player Welfare requirements of the Game.  Without the Laws there would be no Regulations or indeed a Game. The Laws are regularly reviewed by the Laws Review Group and the Rugby Committee. 

For information on 520ccc.com's Law 4 Headgear Trial, information is available here.

520ccc.com are committed to promoting best practice for Player Welfare within the game and welcome innovative thinking on equipment that can be used by players to further Player Welfare and Game Development aspects of Rugby. Where those innovations do not comply with Law 4 (and by extension Regulation 12) they are not ordinarily permitted to be used during Matches.  In such cases, applications supported by detailed scientific evidence as part of an extensive research plan (as further set out below), the Rugby Committee may consider whether the innovation is likely to further the objectives of Player Welfare and Game Development.   

Any recommendation from the Rugby Committee to the Executive Committee, that an innovation be taken forward to a controlled live trial will be based upon a detailed consideration of the benefit of the innovation to the Game including, in particular, those key objectives of Player Welfare and Game Development.  Where a trial of an innovation, which would not otherwise be permitted by Law 4, is approved by the Executive Committee the specific terms of that trial which derogate from Law 4 (and by extension Regulation 12) will apply to that trial for the period the trial is approved. 

The following details must be in place prior to any application for trial being considered:

Research Project 

• A full research project plan with clear outcomes and objectives stated within it, along with specific timelines, must be submitted for review by 520ccc.com.

• The middle layer (sensor) must be no thicker than 2mm (±0.1mm) 
• Testing for impact attenuation must be undertaken under the following conditions and continue to comply with the requirements of Clause 5.4.1 of Regulation 12:

  3. Device with no middle layer (sensor) 
• Any storage or transmitting device must also comply with the requirements for Player Monitoring Devices as described in Regulation 12.
