 Relative to Barnes, II and III are new restrictions, while IV is a substantially broadened version of the main clause of Barnes’ approach—in effect, broadening the relevant goals to include any improvement in the lives of putatively disabled people, whether that comes from social change or bodily transformation. Relatedly, III seems to bring back in medicalization—though now constrained by the requirement that the medical interest in question be “legitimate”, meaning, not apt in the traditional sense (not, concerned with pathology) but rather just or right; morally legitimate in light of whatever morally appropriate role medicine has to play in our society. Lim introduces these conditions to reflect the fact that expert communities outside of the disability rights movement have expertise relevant to constituting the disability population; parents or caregivers, even those not part of the movement itself, may have insight into whether and how a condition affects legitimate interests, while physicians will have important (though not exclusive) knowledge of which limitations on function are legitimately subject to medical interest.
