The High Court has delivered a definitive warning to corporate executives, ruling that a director cannot bypass their board to sabotage a company transaction—even when claiming to act in the interest of national security.
Background:
The dispute centres on a high-stakes corporate power struggle involving Gardner Aerospace, a major UK-based supplier to Airbus and Boeing, and its former CEO, Mr. Upton. Following the 2017 acquisition of Gardner by the Chinese-owned Ligeance Aerospace Technology (LAT), the company operated under National Security Deed intended to protect sensitive UK military and aerospace technology. In 2022, a proposed internal restructuring—referred to as the ‘transaction’—was set to shift control to a Chinese state-owned entity, Shaanxi Dilong Heavy Industries (SDHI). As the Gardner board officially pursued "Plan A" to secure government approval and critical bank refinancing, Mr. Upton secretly embarked on a contradictory path. Believing his own tenure was at risk under the new ownership, he began a unilateral campaign to sabotage the restructuring, leveraging his position to lobby government officials and regulators, suggesting that the deal posed a dire threat to national security and UK jobs, all while positioning himself to lead the company under a potential new buyer through forced divestment.
Decision:
The High Court ruled that Mr. Upton had committed a comprehensive and "remarkable" breach of his fiduciary and contractual duties. The Judge’s reasoning was anchored in the fact that a CEO’s primary obligation under Section 172 of the Companies Act 2006 is to promote the success of the company for the benefit of its members as a whole. By secretly lobbying against the board's agreed strategy, Mr. Upton instead actively worked toward the failure of the company’s primary refinancing plan, which the Court found could have led to Gardner’s insolvency.
The Court rejected Mr. Upton’s defence that he was acting as a "whistleblower" for national security or job protection, concluding instead that these were convenient pretexts used to mask a personal agenda for career self-preservation. Furthermore, the Court found that Mr. Upton breached Section 175 regarding conflicts of interest by negotiating a future role with a competitor and potential acquirer while still employed by Gardner. His failure to be transparent with the board—including providing a heavily "sanitised" version of his government correspondence—was cited as clear evidence of bad faith and a lack of honesty by the objective standards of ordinary decent people.
Implications:
This ruling provides a definitive modern interpretation of the boundaries of directorial autonomy and the absolute nature of the duty of loyalty within English company law. It reaffirms that the "subjective" test of a director acting in good faith under Section 172 is not an unlimited mandate for rogue behaviour, as a director cannot claim they were acting in the company's best interests while simultaneously deceiving the board about their methods. The decision makes it clear that, even if a director identifies a legitimate external risk—such as a national security concern or a threat to the workforce—they are legally obligated to address that risk through the company's established governance structures rather than by embarking upon unilateral, clandestine action. Within the broader legal landscape, the case clarifies that "proper purpose" under Section 171 is strictly tied to the specific goals as authorised by the board, meaning that any executive using their delegated powers to intentionally derail a board-approved transaction is in prima facie breach of duty.
The judgement also strengthens the enforcement of Section 175 by demonstrating that "preparing to compete," or assisting a potential acquirer, while still in office, constitutes a clear conflict of interest, regardless of whether a formal sale process has actually begun. In the age of increasing regulatory scrutiny, particularly regarding foreign investment and national security, this case sets a precedent that the board must remain the ultimate "clearing house" for all material information. It serves as a stark reminder to all corporate officers that transparency is a standalone fiduciary requirement. Hence, actively withholding or editing information to avoid "offending" shareholders or to protect one's own exit strategy is a breach of the duty to keep the board informed.
