The 2023 Currently Active Rule Change Proposals are posted and open for comment here: https://hjdata.ushja.org/rule-changes
Some that jumped out at me as interesting:
003 and 033 - Allowing adults to school ponies at shows (personally seems strange horses can be prepped but not ponies for literal children?)
004 - Limiting the amount of o/f classes a horse can show in, which I think has been discussed/debated here before
007 - Allowing ponies to have a second green year
014- Removing speed classes and combinations in the lower level jumpers (honestly a lot of the time I think combinations help keep rounds slower, and to me is seems dangerous to show over a combination for the very first time at a higher height, but I’m interested to see reactions to this)
028- Clarifying when video review can be used to make a decision, and what video can be relied on. It would leave “only official video footage” as able to be used.
ETA: Question answered!
