Societe Generale, London Branch v Geys

Factual and Procedural Background

The Appellant was employed as managing director of a division within Company A under a written contract dated late-January 2005. The contract contained detailed provisions on notice, payment in lieu of notice (PILON), bonuses and a termination payment formula that varied according to the calendar year in which employment ended. On 29 November 2007 the Appellant was summoned to a meeting, given a letter headed “Termination of Employment” and escorted from the premises. Company A subsequently credited a sum equivalent to three months’ salary to the Appellant’s bank account on 18 December 2007 and sent a further explanatory letter dated 4 January 2008.

The dispute concerned the legal termination date. At first instance Judge Leggatt (sitting as Deputy High Court Judge) held that employment ended on 6 January 2008 and awarded sums to be assessed with an interim payment of £11 million: [2010] EWHC 648. Company A appealed; the Court of Appeal (Judges Arden, Rimer and Pitchford) shifted the termination date to 18 December 2007 and varied other findings: [2011] EWCA Civ 307. The Appellant obtained permission to appeal on two issues; Company A cross-appealed on one issue. The Supreme Court (Judges Hope, Hale, Wilson, Carnwath and Sumption) delivered the present judgment.

Legal Issues Presented

1. Whether a repudiatory dismissal automatically terminates a contract of employment, or whether acceptance by the innocent party is required (“the repudiation issue”).
2. Assuming acceptance is required, when was the PILON clause in paragraph 8.3 of the Staff Handbook effectively exercised so as to terminate employment (“the termination issue”).
3. Whether paragraph 13 of the contract (three months’ notice) conflicts with paragraph 8.3 of the Handbook (PILON) within the meaning of the contractual supremacy clause (“the conflict issue”).
4. Whether paragraph 5.16 and Schedules 1–2 compel the Appellant to waive claims for wrongful dismissal and breach of a tax-efficiency clause as a condition of receiving the contractual termination payment (“the paragraph 5.16 issue”).

Arguments of the Parties

Appellant's Arguments

• The ordinary contractual rule requiring acceptance of repudiation applies; therefore employment did not terminate until Company A validly invoked the PILON clause on 6 January 2008.
• Paragraph 13 and paragraph 8.3 are harmonious; even if there were conflict, the contract prevails, limiting Company A’s PILON rights.
• The termination agreement machinery (paragraph 5.16) does not bar claims for wrongful dismissal or breach of the tax-efficiency obligation; any ambiguity must be construed contra proferentem.

Company A's Arguments

• A repudiatory dismissal automatically ends the contract; employment therefore ended on 29 November 2007, alternatively on 18 December 2007 when payment was made.
• The PILON clause was effectively operated upon payment into the Appellant’s bank account; no additional written notice was required.
• Paragraph 8.3 is contractually dominant or, at worst, qualifies paragraph 13; there is no inconsistency.
• Paragraph 5.16 creates a “clean break”: acceptance of the termination payment obliges the Appellant to waive all contractual damages claims.

Court's Reasoning and Analysis

Repudiation issue. A majority (Judges Hope, Hale, Wilson, Carnwath) preferred the elective theory. They held that automatic termination would unfairly reward the defaulting employer and conflict with general contractual principles permitting the innocent party to choose whether to accept a repudiation. The majority emphasised precedent (Gunton; Boyo) and policy considerations such as employee protection and avoidance of opportunistic breach.

Judge Sumption dissented, finding the automatic theory correct and arguing that longstanding authority up to the 1970s treated contracts of employment as ending upon repudiatory dismissal, with continued existence only for collateral obligations.

Termination issue. The majority (reasons by Judge Hale) ruled that paragraph 8.3 required not just payment but clear, written notification that the PILON right was being exercised. Although funds were credited on 18 December 2007, the first unequivocal written notice was the letter dated 4 January 2008, deemed received on 6 January 2008; employment therefore terminated on that date.

Conflict issue. The Court found no inconsistency between paragraph 13 (three months’ notice) and paragraph 8.3 (PILON). The latter merely qualified the former and could be invoked provided its procedural requirements were met.

Paragraph 5.16 issue. Construed contra proferentem, paragraph 5.16 and Schedules 1–2 did not compel the Appellant to waive claims for wrongful dismissal or breach of the tax-efficiency clause as a condition of receiving the contractual termination payment. Any ambiguity in the employer-drafted documents had to be resolved in favour of the employee.

Holding and Implications

Order: The Supreme Court ALLOWED the Appellant’s appeal, DISMISSED Company A’s cross-appeal, and restored the order of the Deputy High Court Judge.

Implications: The judgment definitively re-affirms the elective theory of termination in UK employment law, clarifies that a PILON clause requires unequivocal notice in addition to payment, and construes waiver provisions in termination agreements narrowly. While establishing no new statutory rule, the decision materially influences contractual drafting and dismissal practices by employers.
