I dont know anything about this case, but the issues highlighted run much deeper. 
My three proposed rule changes 
1) Officials and commentators cannot be in business relationships with mushers. That would eliminate corruption like Mark Nordman living under the wing of Jeff King, and Danny reporting thru the Iditarod site on his family.
2)Mushers must treat handlers as employees under current laws and regulations in their area, to ensure workers rights, protection.
3)Kennel transparency for kennels signed up in the race. To prevent large numbers of dogs being culled like how runyan preaches about in his book and how some high profile kennels still practice these methods.

For the good of the people, dogs, environment health of competition and honoring the mission. If thats not your objective. Than you shuoldnt be involved in Iditarod. 

Martin Buser had a dog with a broke leg and discarded it without care on the trail in 2005 and was not penalized. dogs never break legs in races.
