"17(1) Subject to subsection (3) below, for the purposes of this Act a person becomes homeless intentionally if he deliberately does or fails to do anything in consequence of which he ceases to occupy accommodation which is available for his occupation and which it would have been reasonable for him to continue to occupy …. (4) Regard may be had, in determining for the purposes of subsections (1) and (2) above whether it would have been reasonable for a person to continue to occupy accommodation, to the general circumstances prevailing in relation to housing in the area of the housing authority to whom he applied for accommodation or for assistance in obtaining accommodation."
"16. For the purposes of this Act accommodation is only available for a person's occupation if it is available for occupation both by him and by any other person who might reasonably be expected to reside with him and any reference in this Act to securing accommodation for a person's occupation shall be construed accordingly."
"If the plaintiff had not left the Huntingdon flat in October 1978 she would not have found herself threatened with homelessness in March 1979."
"The background to the case, which has important undertones, is the acute shortage of accommodation in this part of London, the unbearable pressures that homelessness must inevitably bring to individual families, however it may be that they have become homeless, and the difficult and at times almost impossible burden placed on the local authorities in trying fairly to discharge the various duties that Parliament has imposed upon them."
"I cannot think it was Parliament's intention that if an applicant has made himself intentionally homeless earlier than he need be he must be barred from help after he would have been made homeless unintentionally in any event."
"The question which has to be considered is not 'What would have caused him to become homeless if he had not intentionally become homeless?' nor is it 'Would he have become homeless or been threatened with homelessness if he had not already become homeless?' … The real question for the housing authority was 'Were they satisfied he became homeless intentionally?' … I do not myself see how the addition of another cause, whether it be real or hypothetical, can break the chain of causation which still exists."
"… a person becomes homeless intentionally if he deliberately does or fails to do anything in consequence of which he ceases to occupy accommodation which is available for his occupation and which it would have been reasonable for him to continue to occupy."
"Is the applicant's present homelessness the result of a deliberate act or omission on his part in consequence of which he ceased to occupy accommodation which was available for his occupation and which it would have been reasonable for him to continue to occupy?"
"The district council were entitled to reach the conclusion that the plaintiff became homeless on May 25, 1979, intentionally because she deliberately had done something (surrendered the Huntingdon tenancy) in consequence of which she ceased to occupy accommodation (the Huntingdon flat) which was available for her occupation and which it would have been reasonable for her to continue to occupy; and that, therefore, if she had not done that deliberate act she would not have become homeless on May 25 ." (My emphasis.) But if a housing authority are minded to rely against an applicant on the fact that he voluntarily left accommodation on some date in the past as the cause of his present homelessness and to make that the basis of their conclusion that he became homeless intentionally, I do not see how the question how long the accommodation would otherwise have continued to be available for his occupation, hypothetical though it may be, can in all cases be avoided. In a sense perhaps it is a matter of degree. At one end of the spectrum, as already indicated, is the case (as in Dyson ) where there was no reason to anticipate eviction from the vacated accommodation and the housing authority can properly assume that it would have remained available indefinitely. At the other end is the case where a court order for possession has already been made but the applicant, for some reason, leaves voluntarily more than 28 days before the date named in the order when, in the authority's view, it would have been reasonable for him to remain. But between these two extremes there may be an almost infinite variety of circumstances in which an occupier of residential accommodation will find himself in more or less obvious and more or less imminent danger of eviction on grounds which cannot be attributed to any earlier deliberate act or omission on his part and where he may choose to leave voluntarily rather than wait for a court order for possession to be made against him. In any such case, the housing authority, on considering a later application for accommodation under the Act, assuming they find that he left the previous accommodation prematurely, having ascertained the relevant facts, must ask themselves the question: if the applicant had not left his previous accommodation, is it likely that he would now be homeless? If they answer that question in the negative, and that conclusion is one which a reasonable authority could reasonably reach on the facts, their conclusion that the applicant became homeless intentionally will, of course, be beyond challenge in the courts. But if they simply ignore the question, they fail to take account of the relevant issue which arises as to the cause of his present homelessness and thus proceed upon an erroneous construction of the Act. In the instant case the appellants and their four children, in summer 1979, occupied 56, Trinity Road, Wandsworth, which comprised a shop with living accommodation over. Their occupation was under licence from the lessee, a relative, who had moved elsewhere. The business carried on in the shop was not prospering and the appellants found themselves under an ever-increasing burden of debt for unpaid rent and rates. They twice consulted the respondent housing authority and were told that the authority could not help them before there was a court order for possession against them. They left in July 1979 and went to live with the same relative in accommodation at Upminster. In December 1979 they were required to leave this accommodation and made their application to the respondent authority for accommodation under the Act. In notifying (as required by section 8 of the Act) their decision on the application and the reasons for it, the respondents wrote, on 4 th January 1980, to the appellants in the following terms: "
"Put simply on the facts of this case the question that the [housing authority] should have asked themselves was — even if the Dins had complied with the advice given to them in June and July and had remained where they were would they, by the time of their application, have been homeless in any event. The [housing authority] clearly did not consider the point. Had they asked themselves the question the answer on the evidence would have had to be yes."
