arreinment
A court-hearing regarding one or more purported wrongdoings while either perched in da saddle or driving a horse-drawn conveyance of some kind.
If there had been a proper arreinment regarding Genuine Risk's being illegally/unethically prevented from winning da 1980 Preakness Stakes due to da atrocious actions of her opponent's jockey, perhaps she would have gotten her totally-deserved winner's status.
