Expertise

Nick is one of the most highly regarded practitioners at the pensions bar, with specialist knowledge of almost all issues affecting pensions schemes. His cases have concerned the interpretation of trust deeds & rules and legislation (including e.g. indexation issues), the scope and exercise of powers (in particular, amendment powers and the formal validity of amending instruments), the application of equitable doctrines in the pensions context, rectification, the employer debt and scheme funding legislation, the powers of the Pensions Regulator (in particular its financial support direction and contribution notice powers), pensions and insolvency, European law’s impact on pension schemes (in particular in connection with ‘equalisation’) and pensions-related professional negligence claims (concerning solicitors, insurance companies, benefits consultants, professional trustees, actuaries & investment advisers).

Nick has been top-ranked as a pensions expert by Chambers & Partners and the Legal 500 for a number of years. Legal 500 describe him as a “an intellectual giant and tireless worker and inspirational litigation lead counsel in the shoes of an affable gentleman.”

Nick’s wider trusts practice covers other commercial trusts and financial instruments; in particular their interpretation (including applications under section 48 of the Administration of Justice Act 1985); rectification; applications to set aside transactions (on grounds of equitable mistake, the principle in Re: Hastings-Bass, collateral and improper purposes and/or conflicts of interest/duties); and proceedings to challenge or confirm the formal validity of the exercise of powers.

Notable Insolvency cases


Granada Rental & Retail Ltd & Others v The Pensions Regulator [2019] EWCA Civ 1032 | [2019] B.P.I.R. 1121 | [2019] Pens. L.R. 20

A leading authority on ‘connection and association’ under the insolvency legislation and on the interpretation of voting control provisions under debentures.

A leading authority on ‘double dipping’, i.e. the general principle that a creditor cannot recover more than 100% of what is in substance the same debt from two estates. This was an administrators’ application for directions in relation to the Lehman Brothers group. The application resolved the interpretation of the Pensions Regulators’ financial support direction legislation to clarify whether multiple ‘contribution notices’ each claiming Lehman Brothers Ltd’s full statutory debt under section 75 of the Pensions Act 1995 could be claimed against multiple Lehman group companies in administration.

Garvin Trustees Ltd v The Pensions Regulator [2015] Pens. L.R. 1

Concerning the extent to which a company’s legal professional privilege survives its dissolution.

While the appeal decision remains a landmark case on the interpretation of pension scheme contribution rules, the conjoined proceedings at first instance had included Companies Court proceedings challenging the liquidators’ rejection of a proof of debt and ability to go behind prescribed calculation methodologies for relevant debts (with associated disclosure arguments).

Bradstock Group Pension Scheme Trustees Ltd v Bradstock Group Plc [2002] EWHC 651 (Ch) | [2002] I.C.R. 1427 | [2002] O.P.L.R. 281 | [2002] Pens. L.R. 327 | [2002] W.T.L.R. 1281 | (2002) 99(36) L.S.G. 40 | Times, July 10, 2002

The landmark case concerning the extent to which statutory debts under section 75 of the Pensions Act 1995 can be compromised by trustees in the face of impending corporate insolvency, without impermissibly seeking to ‘contract out’ of that legislation. The application was expedited and considered (amongst other matters) whether the trustees’ compromise and payment was at any risk of constituting an unlawful preference.
