• 2012 longs lists and draw process
The FEI's Dressage Committee proposed a long list of judges for the London 2012 Olympic and Paralympic Games according to FEI rules, which state that there can be up to 12 5* judges, a maximum of two per country and from a minimum of eight countries.
There can be only one judge per nation and a total of seven judges on the Ground Juries for the Olympic and Paralympic Games, so the first names to be drawn - providing there is not more than one from any nation - are appointed to the Ground Jury.
The blind draw took place at FEI headquarters overseen by the FEI's legal team.
A total of 11 5* judges from eight nations were on the long list for the London 2012 Olympic Games, including Stephen Clarke who as a host country judge has already been appointed as President of the Ground Jury.
Ten judges from the long list were therefore included in the blind draw: Ghislain Fouarge (NED); Katrina Wüst; Leif Törnblad; Mary Seefried (AUS); Maribel Alonso; Isabelle Judet (FRA); Jean-Michel Roudier (FRA); Gary Rockwell; Wim Ernes (NED); Evi Eisenhardt.
Nine judges were on the long list for the London 2012 Paralympic Games: Lilian Iannone (ARG); Anne Prain (FRA); Freddy Leyman (BEL); Gudrun Hofinga (GER); Tarja Huttunen (FIN); Inga Holdt-Mencke (GER); Kathy Amos-Jacob (FRA); Sarah Rodger (GBR); Carlos Lopes (POR).
The same rules apply for the long list and draw process for the Dressage World Cup.
There were 12 5* judges on the long list: Dietrich Plewa (GER); Isabelle Judet (FRA); Stephen Clarke; Ghislain Fouarge; Gary Rockwell; Susanne Baarup (DEN); Andrew Gardner (GBR); Leif Törnblad; Katrina Wüst; Wojtek Markowski (POL); Francis Verbeek (NED); Susan Hoevenaars (AUS). Jacques van Daele (BEL) is Foreign Technical Delegate at the Reem Acra FEI World Cup Final 2012.
