The three-Judge Bench referred to the Persons with Disabilities (Equal Opportunities, Protection of Rights and Full Participation) Act, 1995 (for short, '1995 Act') and opined that in the said Act also "mental illness" has been defined as mental disorder other than mental retardation. The Court also took note of the definition of "mental retardation" under the 1995 Act. The definition read as follows:
2(r) 'mental retardation' means a condition of arrested or incomplete development of mind of a person which is specially characterised by subnormality of intelligence.
31. The Court also apprised itself that the same definition of "mental retardation" has also been incorporated Under Section 2(g) of the National Trust for Welfare of Persons with Autism, Cerebral Palsy, Mental Retardation and Multiple Disabilities Act, 1999. Analysing the provision of Act. The Court opined that while a guardian can make decisions on behalf of a "mentally ill person" as per Section 3(4)(a) of the 1971 Act, the same cannot be done on behalf of a person who is in a condition of "mental retardation". Thus, the difference between the 'mental illness' and 'mental retardation' as recognized in law, was emphasised.
32. The three-Judge Bench proceeded to address the 'best interest' of the victim and invocation of the doctrine of parens patriae. In that context, it held:
As evident from its literal description, the "best interests" test requires the Court to ascertain the course of action which would serve the best interests of the person in question. In the present setting this means that the Court must undertake a careful inquiry of the medical opinion on the feasibility of the pregnancy as well as social circumstances faced by the victim. It is important to note that the Court's decision should be guided by the interests of the victim alone and not those of the other stakeholders such as guardians or the society in general. It is evident that the woman in question will need care and assistance which will in turn entail some costs. However, that cannot be a ground for denying the exercise of reproductive rights.
33. After so stating, the Court adverted to the facts of the case and came to hold that though the victim had been described as a person suffering from mild mental retardation, that did not mean that she was entirely incapable of making decision for herself. It discarded the 'substituted judgment' test, which requires the Court to step into the shoes of a person who is considered to be mentally incapable and attempt to make the decision which the said person would have made, if she was competent to do so.
