Witnesses that gave evidence to the committee included another jockey who was in the race, Kavish Chowdhoory.
Tait denied the charge of careless riding. But after assessing evidence, the committee ruled the case had been proved, and the degree of carelessness was in the medium range.
Tait was given a suspension of six weeks, commencing on March 10.
She initially faced a seven-week suspension, but the committee’s chair, Jane Lovell-Smith, said the decision took mitigating factors into account, such as Tait’s youth and inexperience.
A statement read to the committee at the end of the hearing from Taylor’s father said seeing his daughter get thrown off the horse and killed was something he could never erase from his mind.
