Supreme Court Rules: Illegal Working Penalty Notices Can Be Invalid If They Fail to State the Specific Reason
IMPORTANT UPDATE FOR EMPLOYERS
If your business has ever received, or is currently dealing with a civil penalty notice from the Home Office for alleged illegal working, the UK Supreme Court has just handed down a decision that you need to know about. The Supreme Court has ruled that a civil penalty notice is legally invalid if it does not clearly state the specific reason why the Home Office believes the employer is liable. A notice that simply lists every possible ground without identifying which one applies to that employer does not meet the legal standard.
This decision could have significant implications for a large number of existing and past penalty notices. If you have received one, I strongly recommend that you contact me immediately so that we can assess whether the notice you received is properly made out.
What Happened in this Case
Akbars Restaurant, a restaurant in Middlesbrough, was inspected by the Home Office in January 2023. The Home Office took the view that the restaurant had employed someone who did not have the legal right to work in the UK. In March 2023, the Home Office issued a civil penalty notice of £15,000.
However, the notice did not clearly specify exactly why the Home Office considered the restaurant to be liable. Instead, it simply reproduced all of the possible legal grounds on which an employer can be penalised under section 15 of the Immigration, Asylum and Nationality Act 2006, without stating which of those grounds actually applied in this case.
The restaurant challenged the notice on the basis that it was legally defective. That challenge failed in the County Court and in the Court of Appeal. However, the Supreme Court has now unanimously agreed with the restaurant. The penalty notice was invalid.
The Legal Background — What Section 15 Requires
Under section 15 of the Immigration, Asylum and Nationality Act 2006, an employer can be made liable to pay a civil penalty if they employ an adult subject to immigration control in specified circumstances. There are four distinct grounds on which liability can arise under the Act, for example, where the employee has no leave to be in the UK at all, where their leave has expired, or where their leave does not permit them to work.
Section 15(6)(a) of the Act requires a penalty notice to state why the Home Office considers the employer to be liable. The question the Supreme Court had to answer was: does a notice comply with this requirement if it simply lists all of the possible grounds together, without identifying which one the Home Office is actually relying on in that specific case?
The Supreme Court's answer was no. It does not.
What the Supreme Court Decided — and Why It Matters
You are entitled to know exactly what you are accused of
The Supreme Court's reasoning is rooted in a basic principle of fairness: if the state imposes a financial penalty on a person or a business, that person or business is entitled to know precisely why. The court put it plainly, saying that one or other of several mutually inconsistent grounds applies does not actually tell the employer why the penalty is being imposed. It leaves the employer to guess.
The notice must stand on its own
The Home Office argued that even if the notice itself was deficient, the employer could work out the relevant ground from other documents exchanged during the appeal process. The Supreme Court rejected this entirely. The obligation under section 15(6)(a) applies to the penalty notice itself, not to the surrounding correspondence. It is the notice that imposes the penalty and it is the notice that requires the employer to make a decision: object, appeal, or pay. That decision has to be made on the basis of what the notice says.
An employer should not have to appeal to find out what they are accused of
This point is particularly significant. In the Akbars case, the restaurant only discovered which specific ground the Home Office was relying on once proceedings were already under way. The Supreme Court found this unacceptable: an employer should not be put in the position of having to appeal simply to discover what case is being made against them.
The notice was invalid — not merely flawed
The court also confirmed that the failure to comply with section 15(6)(a) was not a minor procedural irregularity that could be overlooked. It was a fundamental condition of the notice's validity. This is important because it means the notice did not merely become challengeable, it was invalid from the outset.
The Home Office is, however, entitled to issue a new and correctly worded penalty notice. So where a genuine breach has taken place, the employer is not necessarily free from liability, but the original notice cannot stand.
What This Means for Employers
This decision could affect a significant number of civil penalty notices if the Home Office has been using a standard template notice that lists all possible grounds without specifying the one relevant to each individual case. That now appears to be exactly what was happening.
If you have received a civil penalty notice
The first thing to check is whether the notice clearly identifies which specific ground of liability is being alleged against you. If your notice simply reproduces the statutory language in general terms without pointing to the specific circumstances of your case, it may be legally defective in the same way as the notice in the Akbars case.
This should be checked as a matter of urgency, because there are strict time limits for challenging a penalty notice. Do not wait until the deadline is approaching. Please contact me and I will review the notice with you.
If you have already paid a penalty
Whether there are grounds to recover a penalty already paid is a more complex question that would depend on the specific facts and any earlier proceedings. Again, this is something I can advise you on individually.
What this case does not mean
It is important to be clear about the limits of this decision. The Supreme Court's ruling does not reduce the obligation on employers to conduct right to work checks properly and to keep the correct records. Where a genuine breach has occurred, the Home Office can simply issue a fresh and legally compliant notice. The case is not a general licence to avoid liability — it is a procedural safeguard that protects employers from poorly or improperly made notices.
The best protection against any civil penalty, whether the notice is correctly worded or not — remains a robust right to work checking process carried out in accordance with the Home Office Code of Practice and the employer's guidance. If you follow the correct process and keep the records, you will have a statutory excuse even if the Home Office later contends that the person did not have the right to work.
Practical Checklist for Employers
In light of this decision, I recommend that all employers review the following:
If you have received a civil penalty notice, check immediately whether it clearly identifies the specific ground of liability being alleged, or whether it simply lists all possible grounds in general terms.
If the notice does not clearly specify the ground, contact me without delay. There are strict time limits and you must act promptly.
Review your right to work checking procedures to ensure they comply with the current Home Office guidance. Compliant checks provide a statutory excuse even if a notice is validly issued.
Ensure you are keeping copies of all right to work documents, passports, share codes, and Home Office verification letters, as these records are your primary protection.
If you have any employees on time-limited visas, put in place a system to recheck their entitlement to work before their leave expires. The right to work check is not a one-off exercise.
If you are unsure whether your current practices are compliant, I can carry out a right to work audit for your business. Please contact me to discuss this.
This is a significant ruling that shifts the balance of procedural fairness back toward employers. It confirms that businesses are entitled to know exactly what is alleged against them and that the Home Office must be specific, not merely comprehensive, in its penalty notices.
