23Children affected by disability
(1)Without prejudice to the generality of subsection (1) of section 22 of this Act, services provided by a local authority under that subsection shall be designed—
(a)to minimise the effect on any—
(i)disabled child who is within the authority’s area, of his disability; and
(ii)child who is within that area and is affected adversely by the disability of any other person in his family, of that other person’s disability; and
(b)to give those children the opportunity to lead lives which are as normal as possible.
(2)For the purposes of this Chapter of this Part a person is disabled if he is chronically sick or disabled or suffers from mental disorder (within the meaning of the [1984 c. 36.] Mental Health (Scotland) Act 1984).
(3)Where requested to do so by a child’s parent or guardian a local authority shall, for the purpose of facilitating the discharge of such duties as the authority may have under section 22(1) of this Act (whether or not by virtue of subsection (1) above) as respects the child, carry out an assessment of the child, or of any other person in the child’s family, to determine the needs of the child in so far as attributable to his disability or to that of the other person.
