  Central to this dispute is whether it is preferable to adopt a ‘functional classification system’, which would group together athletes with different disabilities but similar ability levels, or a ‘disability-specific classification system’, which would group together athletes with similar types of disabilities despite different capabilities. At least for the purposes of the quadrennial Paralympic Games, this question cannot be addressed adequately in isolation from the proper aims of the Paralympic Movement, including whether these aims are in contrast with, or even in tension with, those of elite able-bodied sport.
