Local authority – Residential care home. The claimants sought judicial review of the care home payment rates set by the defendant local authority on the basis that the authority's decision was flawed because of its treatment of the return on capital element of their actual costs of running their care homes. The Administrative Court, in dismissing the application, rejected the claimants' contentions including that, because the model on which the decision was based contained a flawed approach to return on capital, as a component of the actual cost of residential care accommodation, the decision had been irrational, had failed to take into account relevant considerations and/or had taken into account irrelevant.
