4.—(1) A person may exceed the usual fostering limit if he is exempted from it by the authority within whose area he lives.
(2) In considering whether to exempt a person, an authority shall have regard, in particular, to—
(a)the number of children whom the person proposes to foster;
(b)the arrangements which the person proposes for the care and accommodation of the fostered children;
(c)the intended and likely relationship between the person and the fostered children;
(d)the period of time for which he proposes to foster the children; and
(e)whether the welfare of the fostered children (and of any other children who are or will be living in the accommodation) will be safeguarded and promoted.
(3) Where an authority exempts a person, the authority shall inform him by notice in writing—
(a)that he is so exempted;
(b)of the children, described by name, whom he may foster; and
(c)of any condition to which the exemption is subject.
(4) An authority may at any time by notice in writing—
(a)vary or cancel an exemption; or
(b)impose, vary or cancel a condition to which the exemption is subject,
and, in considering whether to do so, the authority shall have regard in particular to the considerations mentioned in sub-paragraph (2).
(5) The Department may make regulations amplifying or modifying the provisions of this paragraph in order to provide for cases where children need to be placed with foster parents as a matter of urgency.
