“[42] It is not necessary, for the purpose of deciding this appeal, to express a view on whether any or all of these cases were rightly decided. For my part, I am entirely sympathetic to the proposition that where a local children’s services authority provide or arrange accommodation for a child, and the circumstances are such that they should have taken action under section 20 of the 1989 Act, they cannot side-step the further obligations which result from that duty by recording or arguing that they were in fact acting under section 17 or some other legislation. The label which they choose to put on what they have done cannot be the end of the matter. But in most of these cases that proposition was not controversial. The controversy was about whether the section 20 duty had arisen at all. … [44] … It is one thing to hold that the actions of a local children’s services authority should be categorised according to what they should have done rather than what they may have thought, whether at the time or in retrospect, that they were doing. It is another thing entirely to hold that the actions of a local housing authority should be categorised according to what the children’s services authority should have done had the case been drawn to their attention at the time. In all of the above cases, the children’s services authority did something as a result of which the child was provided with accommodation. The question was what they had done. In this case, there is no evidence that the children’s services authority did anything at all. It is impossible to read the words … a child who is… provided with accommodation by the authority in the exercise of any functions… which are social services functions within the meaning of theLocal Authority Social Services Act 1970 …” to include a child who has not been drawn to the attention of the local services authority or provided with any accommodation or other services by that authority”. … a child who is… provided with accommodation by the authority in the exercise of any functions… which are social services functions within the meaning of theLocal Authority Social Services Act 1970 …”
“The question is: what is the true ratio of the decision in the Hammersmith case? It is plain, in my judgement, that what Baroness Hale, in that passage was contrasting was the facts of the case before the Appellate Committee in which the Children’s Services Authority had done nothing at all and there was nothing as a result of which the child was provided with accommodation in that case which had been done by that authority from the other cases cited to the House of Lords. That, as it seems to me, requires there to be not only some action by the Children’s Services Authority, but also a causal nexus between that action and the result that a child is in fact provided with accommodation. In such circumstances a child will be regarded in law as having been provided with accommodation under section 20 of the 1989 Act, even though, as a matter of fact, the accommodation is provided by the Housing Authority under the 1996 Act. ”
