"21. Offence (1) A person commits an offence if he employs another ("the employee") knowing that the employee is disqualified from employment by reason of the employee's immigration status. (1A) A person commits an offence if the person - (a) employs another person ("the employee") who is disqualified from employment by reason of the employee's immigration status, and (b) has reasonable cause to believe that the employee is disqualified from employment by reason of the employee's immigration status."
"15. Penalty (1) It is contrary to this section to employ an adult subject to immigration control if - (a) he has not been granted leave to enter or remain in the United Kingdom, or (b) his leave to enter or remain in the United Kingdom - (i) is invalid, (ii) has ceased to have effect (whether by reason of curtailment, revocation, cancellation, passage of time or otherwise), or (iii) is subject to a condition preventing him from accepting the employment. … (3) An employer is excused from paying a penalty if he shows that he complied with any prescribed requirements in relation to the employment."
"31. That leaves the question of appeal. It is generally good employment practice to include a right of appeal. Mrs Winstone suggested that it might be inconsistent with immigration law for such a right to be included because it could convey the impression that some form of employment relationship was continuing. I cannot accept that submission for two reasons. Firstly, there is no legal argument before me to support it, so it is a submission made without any substantiation. Secondly, it is clear that in earlier cases there was an appeal and that does not appear to have given rise to any particular difficulty. Nevertheless, I accept Mrs Winstone's submission that in this case there was nothing to appeal against: the test which the employer had to apply is whether before the date of the expiry of the permission it had reasonable grounds for believing that the Claimant had made a valid application for an extension. So, once the date had passed, there was no basis for the employer to, as it were, back calculate or back-fill a belief it did not have on 12 August. In those circumstances, while not ideal, I cannot say looking at it as a whole that it was unfair to fail to offer a right of appeal in the dismissal letter. 32. In reaching this conclusion, I also bear in mind the continued contact between the parties after dismissal, which included an open offer to reengage the Claimant, albeit as a new starter. So, there was no question of the Respondent not wanting to have the Claimant back, it simply was a question of what terms should apply as to continuity and back pay."
"(4) Where the employer has fulfilled the requirements of subsection (1), the determination of the question whether the dismissal is fair or unfair (having regard to the reason shown by the employer) - (a) depends on whether in the circumstances (including the size and administrative resources of the employer's undertaking) the employer acted reasonably or unreasonably in treating it as a sufficient reason for dismissing the employee, and (b) shall be determined in accordance with equity and the substantial merits of the case."
