Functional equivalents to constitutional review play out in various courts as a new legal game of power and counter-power shapes up for the global age.

I propose to put on constitutional lenses to analyse the current case pitching speed skater Claudia Pechstein against the International Skating Union (ISU) in front of the Bundesgerichtshof.
