The Supreme Court of India granted custody of a man suffering from cerebral palsy to his mother, a US national, after determining it was in his best interest due to his inability to make independent decisions. The court overruled a Madras High Court decision, finding the lower court's interaction with the son insufficient to assess his needs. The Supreme Court emphasized the son's limited cognitive capacity and the availability of specialized support in the US, where he had completed most of his schooling.
