Notable Cases:

  • Supreme Court success in the immigration nationality case of Hysaj & Ors, R which significantly changed the case law on deprivation and nullity of British Citizenship under the British Nationality Act 1981.
  • Acted in the 2017 immigration Court of Appeal matter of LC (Albania) which led to the Home Office to acknowledge that out of date country guidance evidence had been relied on in error by the Home Office and Courts for over 5 years to dismiss domestic violence, trafficking and sexual identity related asylum claims from Albania.
  • In July 2017, acted in a Libya country guidance case that successfully challenged removals to Libya, based on the lack of state protection for civilians. It became an authoritative precedent that anyone from Libya, regardless of the region they are to be returned to, would be at risk of return contrary to international and EU law.
  • Acted in a lead immigration judicial review challenge that led to the High Court ruling that the ‘Fast Track Procedure Rules’ used by the Home Office to consider asylum cases until 2014 were unlawful. The case has enabled more than 10,000 asylum seekers to potentially request to have their cases reconsidered.
  • Represented torture victims in an unlawful detention claim that successfully challenged the Home Office’s “Adults at risk in immigration detention policy”. Consequently, the High Court declared the Government’s immigration detention policy for torture victims to be unlawful as it wrongly allowed many who had been recognised as tortured overseas by ‘non state actors’ to still be detained. The Home Office was ordered to review its policy on incarcerated torture survivors and release those unlawfully detained as a result.
  • Acted in an immigration detention case where the Home Office was found to have acted unlawfully by locking up a Kenyan asylum seeker in segregation, in a so-called “punishment room” for too long. Despite several thousand people being placed in immigration detention segregation every year by the Home Office, this case was reported to be the first challenge regarding the use of segregation in immigration detention centres.
  • Advising two unions, the Locum Doctors Union (LDU) and Healthcare Professionals Union (HPU) in relation to allegations that NHS Improvement (NHSI) continues to instruct NHS Trusts, contrary to its own guidance, to apply a blanket determination that all locum doctors and nurses are inside IR35 so that National Insurance and Tax had to be deducted at source.
  • Represented the M, in a case concerning her four children. M, worked as a secretary for the X High Commission. The family entered the UK with diplomatic rights and privileges prior to M leaving that employment. There were two key issues in the case; the first concerned the court’s jurisdiction to make final care orders in respect of the children if those children continued to have diplomatic immunity. The second consisted of classic welfare issues in children public law proceedings which require threshold criteria to be satisfied. Following intensive legal work, the court further concluded it is in the best interests of the children to return to the care of M following a period of rehabilitation managed by the Local Authority.
  • Acted for the tenant in the 2016 landmark Court of Appeal social housing case of Cardiff County Council v Lee (Flowers). The case changed the law, confirming that all landlords, whether social or private, are required to seek the permission of the County Court in order to obtain a warrant of possession for breach of a suspended possession order with costs sanctions if not followed, providing an additional level of protection for tenants.
  • Represented the respondent in the 2015 Supreme Court case of Gohil v Gohil, a divorce financial settlement case which established the principles in relation to material non-disclosure and the basis upon which an agree financial consent order can be set aside and the case re-opened if a party has not provided full disclosure at the time of the original trial.
  • In 2016, represented the imprisoned convicted killer Joanna Dennehy in her claim for damages on account that her two year solitary confinement in prison breached her human rights.

  • Brexit and non-EU Immigration

    There is no doubt that the UK has to date benefited immensely from visa-free EU immigration to the extent that visa conditions and caps on non-EU migrant have undermined and overshadowed the ability of this group to play a prominent role in British industry and commerce and in its expanding and overburdened NHS service. It is the view of  Gulbenkian Andonian  however, that after  Brexit, there should be a noticeable change in those skilled non-EU migrants contributing to British society in a meaningful way.

  • Have Changes to The Spouse/Civil Partnership Minimum Income Threshold Made A Difference?

    The plight of those denied a UK Spouse/CivilPartnership Visa or a Spouse/Civil Partnership Visa extension continues to feature in the headlines.   In August 2018, the Guardian reported on one young woman, driven to attempt suicide after her fiancĂ©, an Albanian national, was not permitted to enter the country.   The Home Office ruled Paige Smith, a British Citizen, did not meet the ÂŁ18,600 income threshold.   It later transpired the Home Office lost a crucial payslip proving that Ms Smith met the criteria, a document the department had been sent four times by a Solicitor and Ms Smith’s MP.   The appeal Judge took ten minutes to rule the Visa should have been approved; however, the couple still had to wait two months for the Home Office to declare it would not appeal the decision.
