I thought I would start a new thread to focus on issues of dressage judging as separate from the “Horse Welfare” thread.
Take my comments with the disclaimer that I admit I am biased. I am a dressage dinosaur who likes training horses but who no longer likes to watch competitive dressage.
The FEI has a Dressage Judging Manual. to give judges guidance.
DRESSAGE JUDGING MANUAL (fei.org)
My point of reference is Wolfgang Niggli’s 2003 book, “Dressage - A guideline for Riders and Judges”
This book is only 20 years old, but his words seem “quaint” in the current state of affairs.
