Yellow must give room. If yellow fails to respond she is DSQ under 20.2(. The protest committee has no choice
So, yellow must give room and then yellow must then file a rule 2 protest and request redress under rule 62.1(d). She must also request the protest committee consider rule 69.2©
I suspect that in reality yellow needs witnesses to pull this one off.
Yellow can only gain redress if committee disqualifies red under 2 or 69.2©. What redress yellow gets is governed by 64.2. Don't hold your breath!
