London Ambulance Service NHS Trust v Small: This case is a reminder that the tribunal's role in unfair dismissal cases is not to substitute its own view, but to determine whether the decision to dismiss fell within the band of reasonable responses open to the employer. The Court of Appeal reaffirmed that, in deciding whether an employer's decision to dismiss fell within the band of reasonable responses, the tribunal should consider only those facts reasonably known to the employer when dismissing the employee.
