In Kaltoft v Municipality of Billund (C-354/13) the Advocate General has given the opinion that obesity may amount to a disability for the purposes of the EU Equal Treatment Framework Directive (No.2000/78) but only if it is ‘severe’. The Advocate General thought it probable that only obesity with a body mass index (BMI) of over 40 would hinder an individual’s participation in professional life to such an extent as to amount to a disability. He also rejected the argument that there is a freestanding prohibition in EU law on discrimination on the ground of obesity per se.
