In April 2015, the Supreme Court dismissed an appeal bought by The Trustees of the Olympic Airlines SA Pension and Life Assurance Scheme ("the Scheme") and held that Olympic Airlines SA ("Olympic Airlines") did not have an "establishment" in the UK when the Trustees presented a winding up petition in England on 20 July 2010.

The significance of the decision is that without a "qualifying insolvency event", the Scheme would not enter the Pension Protection Fund ("PPF") and is of significance for any defined benefit pension scheme of a UK branch office of an overseas company.
