The U.S. Equestrian Federation Hearing Committee recently heard a protest filed against Elizabeth Mandarino by another USEF member. The protest alleged that certain USEF rules were violated at the 2012 Devon Horse Show (Pa.) on May 26, when Mandarino administered an injection to her pony, Humble, and thereby caused his death.

The USEF Hearing Committee ruled that the protest must be dismissed for lack of substantiation. The Hearing Committee noted in its findings “…that the proof available at [the hearing] was not sufficient to answer the complex medical/toxicological questions that underlie the central allegation in the protest.”
