6. The Commissioner may only examine the case of a particular child where
(a)a representation is made to the Commissioner by the child concerned or, if the child is unable for any reason to make such a representation, where a representation is made to the Commissioner on behalf of the child by a person who, in the reasonable opinion of the Commissioner is suitable to make such a representation;
(b)the Commissioner considers that the representation raises a question of principle which has a more general application or relevance to the rights or welfare of relevant children than in the particular case concerned; and
(c)the Commissioner has taken into account whether the issues involved in the case have been or are being formally considered in any way by other persons and if they have not or are not whether, in the Commissioner’s opinion, they are more suitable for consideration by other persons.
