The Legal 500 2011 - Oliver Longstaff, who takes a 'highly client-centred approach'.

Recently Concluded Cases

In 2010, Oliver acted for the families of two out of three deceased in inquests arising out of the acquittal of a County Durham G.P. on charges of murder. The coroner concluded that the patients concerned would not have died when they did but for the administration to them of morphine, diamorphine and chlorpromazine, and described the injections of these drugs as "not clinically justified".

Other inquests in which he has appeared have included the deaths of patients (including a patient detained under the Mental Health Act 1983) in hospital and local authority care, the suicide in prison of a convicted child abuser, and a double inquest into the murder of a wife by her husband, who then killed himself. He has also acted for the families of numerous victims of asbestosis and mesothelioma.

In the civil courts, Oliver acted for the claimant in a clinical negligence trial concerning whether a decision not to treat a patient's presenting condition could be justified with reference to the House of Lords' decision in Bolitho v City and Hackney Health Authority [1997] 4 All ER 771. He also represented the claimant in a professional negligence case where the failure by a solicitor acting for a borrower to advise the loan guarantor to seek independent advice resulted in the guarantor (an elderly relative of the borrower) being at risk of losing her home.

Oliver's other notable cases include securing compensation for an adolescent boy with learning difficulties who injured himself as a consequence of being placed in inappropriate accommodation by his local authority, and quantum trials with a value in excess of £500,000.


Oliver has delivered lectures to solicitors on employers' liability and civil procedure (including costs and conditional fee agreements), and to audiences of senior clinicians and hospital claims managers on inquests and clinical negligence litigation.
