Vadim Don Benyatov v Credit Suisse (Securities) Europe Ltd

This was not a routine employment dispute. It grew out of cross-border investment banking work, a long-running foreign prosecution and the practical effect that a criminal conviction can have on a regulated career.

Mr Benyatov was a senior Credit Suisse banker working on Romanian privatisation projects. In 2006, while in Romania for work, he was arrested and later prosecuted in connection with the Electrica Muntenia Sud privatisation. He denied wrongdoing and said the prosecution was politically motivated.

The bank did not abandon him. It investigated the allegations, concluded that he and the other employees involved had done nothing wrong, paid for lawyers and supported his defence over many years. He remained employed by the bank during that period.

The turning point came in 2013 when he was convicted in Romania. Although the FCA did not take action against his registration because he was already on garden leave and not carrying out regulated activities, it was common ground that the conviction effectively ended his ability to work as a regulated financial professional. That practical barrier sat at the centre of the claim.

He later sued the bank in England, saying that the conviction and its consequences had destroyed his banking career and future earning capacity. He sought compensation for very substantial lost earnings.

The claim was put in two alternative ways.

First, Mr Benyatov brought a negligence claim. He said the bank owed him a duty of care not to expose him to criminal conviction in the performance of his duties. His pleaded case said the bank should have assessed the risks of working in Romania and on transactions that might expose him to criminal conviction, communicated the results of that assessment, and given any necessary training or advice so he could mitigate those risks.

That meant the negligence case was not only about what happened after his arrest. It was also about what the bank should allegedly have done before and during the work, including whether Romania and the relevant transactions were high-risk and whether warning signs were known or should have been known.

Second, he argued that his employment contract contained an implied indemnity. This was the broader argument. In substance, he said that because the loss arose from him doing the job the bank employed him to do, the bank should compensate him even without proving fault in the same way as a negligence claim.

He also relied on an unlawful-enterprise indemnity theory, based on the idea that an employer may indemnify an employee against liabilities arising from an unlawful enterprise if the employee did not know it was unlawful. But that argument depended on the scope of the underlying indemnity and did not create a wider free-standing right.

The Court of Appeal framed the appeal as raising an issue about when an employer may be liable to compensate an employee for loss of earnings caused by the act of a third party in consequence of the employee doing their job. That framing is what gives the case wider business value.

On negligence, the question was whether the pleaded duty of care existed in the form argued for. Could an employer be under a duty broad enough to assess and guard against the risk of an employee being convicted in a foreign jurisdiction while carrying out work for the business?

On contract, the question was whether the law should imply an indemnity broad enough to make the employer bear career-long financial loss, even where the immediate cause of that loss was a third party’s act and there was no employer fault. The court had to consider implication both as a matter of law and as a matter of fact.

The appeal also involved factual arguments about what the bank knew, whether alleged warning signs had been established, and whether the claimant had shown actual or constructive knowledge of relevant risks.

The Court of Appeal dismissed the appeal. It upheld the trial judge’s decision rejecting both the negligence claim and the contractual indemnity claim.

On negligence, the court did not accept the duty of care case in the way it had been pleaded. It also rejected the claimant’s challenges to the trial judge’s factual findings about the bank’s knowledge of alleged warning signs and whether the relevant risks had been established. The negligence claim therefore remained dismissed.

On the contractual side, the court rejected the argument for a broad implied indemnity requiring an employer to compensate an employee for all losses, including lost earnings, suffered as a result of doing the job. The court said English authority did not support a general principle that a person acting on another’s instructions is entitled to be indemnified against all losses of any kind suffered as a result.

The court was concerned that such a term would impose a form of strict or no-fault liability far beyond recognised employment duties. It said the relationship between employer and employee is already addressed through appropriate duties of care and employment protection legislation. That did not justify making the employer, in effect, the employee’s insurer in respect of all harm suffered in consequence of work.

The court also rejected the argument that an indemnity should be implied as a matter of fact on these particular facts. The claimant’s case depended heavily on the proposition that the work in Romania was high-risk in the relevant sense. The judge’s earlier factual findings meant that the necessary foundation for that argument had not been established.

As for the unlawful-enterprise indemnity point, the court treated it as adding nothing wider. If the broader indemnity claim failed, that claim failed too.

The useful lesson is not that employers are safe whenever a third party causes the immediate harm. Nor is it that overseas risk does not matter. The real lesson is that courts are cautious about expanding employer liability beyond recognised duties and clear contractual promises.

For business owners, that matters because the losses claimed in cases like this can be enormous. If the law implied a general indemnity for all work-connected losses, businesses could face open-ended claims for future earnings even where they had not acted negligently. The Court of Appeal was not willing to create that kind of exposure through implication.

The case is especially relevant if your business sends staff overseas, works in regulated sectors, or handles politically sensitive or high-value transactions. Those settings can create legal, regulatory and reputational risks that are difficult to predict and expensive to manage.

The court did not say employers can ignore those risks. It simply refused to convert them into a blanket promise to cover every downstream financial consequence. That is an important distinction. Risk management still matters, but it should be approached as practical governance rather than as an assumed all-purpose indemnity.

If your staff work across borders or in regulated roles, this case is a prompt to review how your documents and internal processes fit together. The aim is not to eliminate all risk. It is to define responsibilities clearly and reduce later arguments about what support or protection was supposedly built into the employment relationship.

Start with the employment contract. If a role may involve overseas travel, local-law exposure, contact with regulators or politically sensitive work, the contract should not describe the role in vague generic terms only. It should reflect the real operating model.

Then look at policies and approvals. A policy can explain how the business expects staff to handle higher-risk work in practice, including sign-off routes, escalation steps and when local advice should be sought. That kind of framework can be proportionate even for smaller businesses if the work genuinely carries extra risk.

Finally, think carefully about support arrangements. Some businesses choose to provide legal support or reimbursement in investigations or proceedings. If so, it helps to state the scope clearly. For example, is support discretionary, who decides, what costs are covered, and does support continue after employment ends? The case shows the danger of leaving those questions to implication after the event.

This decision should not be read as a green light to be casual about overseas or regulatory risk. It is better read as a reminder that ordinary risk management and clear drafting do the heavy lifting.

If your business enters unfamiliar jurisdictions, consider whether staff need a structured briefing before travel or project work. That may include local legal sensitivities, reporting lines, document handling, contact with public officials and what to do if authorities approach them. The right level of formality will depend on the size of the business and the nature of the work.

For regulated businesses, think about the practical consequences if an employee becomes subject to allegations, proceedings or a conviction. Even where a regulator does not take immediate formal action, the commercial effect on the person’s role may still be severe. Internal planning should recognise that reality.

Most importantly, avoid overstating what the business will do. If support is discretionary, say so. If insurance exists, explain its limits. If the business expects employees to comply with local law and internal approvals, make that expectation clear and workable in practice.

If you are reading this on a phone, the short version is simple. The employee lost. The Court of Appeal would not impose a broad implied indemnity making the employer pay for career-long lost earnings caused by a foreign conviction connected with work. It also upheld the rejection of the negligence claim as pleaded.

That does not mean employers have no duties. It means the court would not stretch those duties, or imply a new contractual promise, so far that the employer became the employee’s insurer against all serious work-connected financial harm caused by a third party.

This is a Court of Appeal decision in Vadim Don Benyatov v Credit Suisse (Securities) Europe Ltd [2023] EWCA Civ 140. Judgment was handed down on 17 February 2023. The appeal was from the High Court decision of Freedman J, reported as [2022] EWHC 135 (QB), and the appeal was dismissed.

For business readers, the durable point is narrow but important. The case rejects a broad implied indemnity for lost earnings on these pleaded claims and facts. It should not be overstated as a universal rule about every employer duty or every kind of employee loss.
