Is it reasonable for an employer looking into allegations of misconduct to refuse to undertake further investigations that could support an employee's case? No says Brian Palmer of our Employment Team, particularly where gross misconduct is alleged.

In a recent Employment Appeal Tribunal (EAT) case called Stuart v London City Airport, Mr Stuart was employed as a Ground Services Agent at London City Airport (LCA). He entered a duty-free store within the airport to buy some presents. While queuing to pay, he was beckoned outside the store boundary to a seating area by another member of staff and went to speak to her.  At that point he was apprehended by the police for dishonestly removing goods without payment.  Mr Stuart argued that he had no intention of stealing the items and that he felt that he was still in the general shop area.  Mr Stuart had an impeccable record and his most recent appraisal graded him as excellent.

In dismissing Mr Stuart, LCA relied primarily upon their conclusion that he had in fact left the store boundary with the unpaid items and upon the strongly disputed evidence of a store assistant who had informed her store manager that she saw Mr Stuart conceal items in his jacket before he left the store.

The evidence of the store assistant was never tested orally during the internal appeal or subsequent Tribunal proceedings. During the internal proceedings, LCA refused to interview the store cashier or the staff member who beckoned Mr Stuart outside of the store boundary. Further, LCA also failed to consider available CCTV footage of Mr Stuart's movements inside the store.  The CCTV footage would have assisted in determining the allegation of concealment and, therefore, whether Mr Stuart's conduct was dishonest.

When deciding whether a dismissal is fair or unfair, an Employment Tribunal (ET) should not decide whether it considers the employee is guilty of the misconduct, but rather whether the employer had reasonable grounds for believing that the employee was guilty. The ET must review the level of investigation undertaken by the employer and consider whether it was within, what is commonly referred to as, a 'band of reasonable responses' – or in other words one which a reasonable employer would have undertaken in the circumstances.  While the ET in this case held that the investigation was reasonable and the dismissal fair, the EAT ruled that the employer's investigation did not go far enough.

Of particular importance to the EAT in reaching its decision was the fact that the misconduct at issue related to the claimant's honesty. Although the employer had conducted an investigation prior to dismissing the employee, there was other evidence readily available which was ignored. CCTV footage may well have proved whether Mr Stuart had been acting dishonestly in the shop. The EAT ruled that the failure of LCA to carry out investigations, which could have supported Mr Stuart's account that he was at no time acting dishonestly, was objectively unreasonable and, therefore, unsustainable.

What does this mean for employers?

This case is an important reminder to employers that, in cases where an employee's integrity is in question, a higher level of investigation may be required to establish the employee's guilt (or otherwise). This is especially so where the employee raises a plausible defence to a serious allegation. The employer, as investigator, must be seen to be even handed and look for evidence which proves innocence as much as it does to look for evidence which proves guilt.
