Significant Experience

  • Allan advised the seven Welsh Health Boards on proceedings brought against them by a number of care home providers challenging payments made to them for Funded Nursing Care. The care homes were supported by 21 of the 22 Local Authorities in Wales and the case went to the Supreme Court on 26 April 2017. The Judgment will have ramifications for all care homes and patients in receipt of funded nursing care in both England and Wales (see Forge Care Homes and Others –v- Cardiff and Vale University Health Board and others).
  • Allan advised NHS England in relation to a challenge brought by the Hepatitis C Trust, seeking to quash NHS England's decision to implement recommendations as to the use of three new drugs to treat hepatitis C made by the National Institute for Health and Care Excellence ("NICE"). The recommendations were the first ever to require prioritisation of treatment to those with the highest unmet clinical need. The Court rejected the claim, concluding NHS England's approach represented a rational way of identifying those to whom treatment should be given as a priority. (see R(oao) Hepatitis C Trust –v- National Health Services Commissioning Board).
  • Allan advised a local authority in receipt of a procurement challenge to the award of a 10 year contract for building supplies, where allegations were made of discrimination and unfair treatment, as well as manifest errors. Matters were resolved through mediation.
  • Allan advised the developer of a proposed gas-fired power station to be built in the North of England in relation to a multi-million pound claim concerning its contractual obligations to proceed with construction and secure statutory consents for the project. The threat of proceedings was successfully removed.
