Both Sam Waley-Cohen and Nina Carberry who were due to sit out Grand National day due to bans will now be eligable to ride on the day.
The BHA said: "Owing to ambiguous wording of the rule, suspensions imposed on Sam Waley-Cohen and Nina Carberry will no longer apply on Grand National day.
"The representation pointed to the fact the clause relating to [bumper] races refers specifically to races confined to amateur and conditional riders, however the clause relating to hurdle races refers only to races confined to amateur riders."
It would appear that this loop-hole was pointed out to the BHA by Sam who explained "After I was given the days I asked why I would be banned on Grand National day, given the wording of the rule is quite specific and says bans apply on days when there is an amateur riders' chase, an amateur riders' hurdle or a conditional and amateur riders' bumper and On the day in question there is only a conditional and amateur riders' hurdle".
It added: "The BHA will take steps to amend the schedule to ensure future amateur suspensions correctly reflect the aforementioned intention"
