Work highlights

Mark has acted in many of the leading contentious pensions matters over the past 25 years. A few highlights include:

  • British Airways PLC: advising in its ground-breaking claim against the Trustees of the Airways Pension Scheme over their decision to implement discretionary pension increases above the increases provided by statute, in a scheme with a substantial deficit. We won the case before the Court of Appeal and it has since been settled.
  • BHS pension schemes: advising Taveta companies in the well-publicized regulatory proceedings brought by the Pensions Regulator against Sir Philip Green and certain group companies by way of financial support directions and a contribution notice in relation to the BHS Pension Schemes. The case was settled.
  • Southern Water: advising in novel regulatory proceedings brought by the Pensions Regulator to exercise its scheme funding powers. The case was settled and is the subject of a s89 report by the Regulator.
  • Lehman pension scheme: advising the administrators of Lehman companies in regulatory proceedings brought by the Pensions Regulator for a financial support direction which proceeded to the Upper Tribunal. We successfully defended the case before the Supreme Court over whether the claim was an expense in the administrations and the claim was thereafter settled.
  • Nortel pension schemes: advising Nortel Networks Inc in its dispute with the trustee of the Nortel UK scheme and the PPF over a financial support direction and claims made in the Ch 11 Bankruptcy. The case was settled shortly before it was due to go to trial before the US and Canadian Bankruptcy Court.
  • MNRPF: advising the trustees of the scheme in a complex case which concerns the scope of amendment powers in the scheme and ill-heath early retirement benefits. A court approved compromise in the case was ordered in 2022.
  • Granada: advising the Trustee of the Granada Supplementary Pension Scheme in successfully defending before the Court of Appeal, a claim by Granada that security arrangements set up under the “top up” scheme contravened Companies Act 1985 restrictions as there was no shareholder approval for them and as a result the security held by the trustees must be released.
