Council tax challenge goes to the Court of Appeal 12 February 2013 Last updated at 08:17 A single mother is taking her legal battle over a north London council's plans to make people on benefits contribute to their council tax bill to the Court of Appeal. A High Court judge had dismissed claims Haringey Council's consultation over the changes were flawed. He said the process was not unlawful but gave the woman leave to appeal. Local authorities are being asked to introduce their own council tax reduction schemes from April. A study by the Resolution Foundation independent research group in January found nearly 75% of local authorities in England were planning to increase demands on low-income families. Positive incentives The woman, who has four children but cannot be named for legal reasons, complained Haringey Council acted unlawfully when consulting on its council tax reduction scheme. The council said its consultation process was extensive, clear and comprehensive. Mr Justice Underhill dismissed her claim on 7 February but her solicitors will ask three appeal judges to overturn that ruling later. Haringey Council's consultation, involving claimants, residents and key stakeholders, ran from August to November and included the council writing to the 36,000 households directly affected. A spokesman for the Department for Communities and Local Government said: "Under the new localised system, councils are legally responsible for drawing up their schemes. The government has provided £100m of transitional funding to help all councils develop well-designed schemes, maintain positive incentives to work and encourage best practice.
