Sheryn is able to advise upon both English and Australian law and to appear in courts in England and Wales, and Australia.

Sheryn was junior counsel for the Claimant drivers in the Employment Law case of our time Aslam & Farrar v Uber BV & Ors in which the Supreme Court found that Uber drivers are workers.

She is presently instructed on behalf of the Applicant Uber drivers in Weddall & Ors v Rasier Pacific, Uber Pacific Pty Ltd & Ors, employment status litigation against Uber in the Federal Court of Australia. She is the only barrister in the world to be instructed on two employment status cases against Uber across different jurisdictions.

Above all else, she understands that litigation can be stressful for those she represents, and she is empathetic.” - Legal 500 2023

  • Sheryn Omeri KC specialises in all aspects of Employment and Discrimination Law, including employment status, territorial jurisdiction and whistleblowing, as well as Public Law, Human Rights and Public International Law, International Criminal Law, and Clinical Negligence Law. Sheryn is instructed to appear at all levels of the Tribunal and Court structure, including the Employment Tribunal, EAT, County Court, High Court, Court of Appeal and Supreme Court.

    EMPLOYMENT LAW

    Sheryn was instructed (together with Jason Galbraith-Marten KC) on behalf of the lead Claimant Uber drivers in the employment status case of Aslam & Ors v Uber BV and Ors [2021] UKSC 5, in which the Supreme Court held that Uber drivers are workers.

    Sheryn appeared for the Respondent (led by Jason Galbraith-Marten KC) in the cross-over employment/human rights case of Turner v East Midlands Trains [2013] ICR 525 in which the Court of Appeal held, consistently with the Respondent's case, that the range of reasonable responses test applicable to cases of alleged unfair dismissal complies with the UK's obligations pursuant to Article 8 of the European Convention on Human Rights.

    PUBLIC LAW

    Sheryn is Head of Cloisters' Public and Administrative Law Group. She is instructed (together with Sonali Naik KC and Irena Sabic KC) on behalf of an asylum seeker who was unlawfully detained pursuant to the Detained Fast Track procedure in a case concerning Public, Immigration and Personal Injury Law.

    PUBLIC INTERNATIONAL LAW

    In early 2015, Sheryn worked in the Prosecution Division of Office of the Prosecutor at the International Criminal Court in The Hague, principally on the case of Prosecutor v Al Faqi Al Mahdi. This was the first prosecution for the war crime of destruction of cultural property and the first occasion upon which a defendant offered to plead guilty before the ICC in the history of that court.

    In 2018 and 2019, Sheryn was invited to speak at the Peace Palace at the Annual Conference of the IBA's War Crimes Committee.

    Previously, Sheryn was instructed by the Kurdish Human Rights Project (now the Democratic Progress Institute) to act for one hundred Armenian workers in a case pending before the European Court of Human Rights.

    PERSONAL INJURY / CLINICAL NEGLIGENCE

    Sheryn is regularly instructed to advise on and appear in personal injury and clinical negligence cases on the multi-track and in the High Court. Sheryn is presently instructed on behalf of the Claimant, victim of internal trafficking, in a high value personal injury claim against a brothel owner. In 2016 Sheryn appeared in the High Court case of London v Southampton City Council on behalf of the Claimant widow and executrix of the estate of Geoffrey London who had passed away as a result of the negligence of the Defendant.

    PRIOR TO CLOISTERS

    In Australia, Sheryn was judicial assistant to the Honourable Justice Margaret Beazley AO, President of the New South Wales Court of Appeal and first woman to be appointed to that Court. Following this, Sheryn worked for and advised the Coalition of New South Wales Aboriginal Legal Services, the peak body representing the interests of the six Aboriginal and Torres Strait Islander Legal Services in New South Wales (ATSILS). Sheryn also published extensively, drawing attention to the discriminatory practices of police and courts in relation to Aboriginal Australians.

    After the fusion of the six ATSILS, Sheryn worked as a criminal defence solicitor (advocate) and appeared in the Local, Children's, District and Supreme Courts of New South Wales on behalf of Aboriginal clients charged with all manner of criminal offence.

    Sheryn was invited to the UK to work at Doughty Street Chambers where she became researcher to Richard Hermer KC in his capacity as head of the International Law Team. Later Sheryn worked for Leigh Day & Co Solicitors, specialising in product liability and was involved in multi-claimant actions with an international dimension.
