Starting in around February 2015, class rule changes were introduced and discussed within the IRSA Technical Committee. The proposed rule changes were circulated to IRSA Designated National Members (DNMs) around December 2015 and January 2016. A number of DNMs responded with comments, and these were addressed by the TC Chairman. The proposed revised class rules were then brought to the Executive Committee by the TC Chairman in March 2016, which the EC formally voted on and approved. The rules, and an explanation of the changes, were published in April 2016, and came into effect in July 2016 after minor errors were found and edits made. This is the process which has been used in the previous decades of rule changes by the IMYRU, ISAF-RSD, and now IRSA.
