In Klusova v London Borough of Hounslow [2007] EWCA Civ 1127, the Court of Appeal upheld a finding of unfair dismissal in the case of an employee who was dismissed on the grounds that she was no longer entitled to work in the UK. There was evidence to support the tribunal's finding that the employee was, in fact, legally entitled to work in the UK at the time of her dismissal. While the employer's mistaken belief about her immigration status was capable of amounting to "some other substantial reason" for dismissal, the fact that the employer had failed to follow the statutory dismissal procedure rendered the dismissal automatically unfair.
