The overstayer exception: paragraph 39E, now SUI 13.1.

What is now SUI 13.1 of the Immigration Rules was, until 11 November 2025, paragraph 39E. The provision is widely known as the fourteen-day rule. The description was unhelpful when it described paragraph 39E and is no more helpful now that it describes SUI 13.1. The provision is not a fourteen-day grace period for applicants whose leave has expired. It is a narrowly drawn exception in two principal limbs — one of which has almost nothing to do with the fourteen days that give the popular name its currency — and the standard of what counts under either limb is stricter than the casual reader would assume from the label.

Paragraph 39E was introduced into the Immigration Rules on 24 November 2016, replacing an earlier regime under which the consequences of overstaying could be softened by a written “out of time” concession issued by the Home Office. That regime was more flexible and more arbitrary; 39E was less flexible and more predictable. Both versions existed against the same structural fact: the Immigration and Asylum Act 1999 and the Immigration Act 1971 together create a regime in which overstaying without leave is a matter of strict statutory effect, and any softening of that effect has to be built into the Rules deliberately.

On 14 October 2025, Statement of Changes HC 1333 introduced a harmonised Part Suitability across the Immigration Rules. Among many other changes, the substance of paragraph 39E was relocated into Part Suitability as SUI 13.1, with the relocation taking effect on 11 November 2025. The two limbs that gave 39E its operational shape carried across, and three further categories — covering the COVID-19 period, the Hong Kong British National (Overseas) route, and the “exceptional assurance” concession — were drawn in beside them. The relocation reflects the regulator’s view that the overstayer exception is properly read as a question of suitability rather than as a structural feature of the Rules at large.

Since the relocation, the case-law decided under paragraph 39E has continued to inform interpretation under SUI 13.1. The substance of the two limbs is materially unchanged, the statutory architecture around section 3C is unchanged, and the operational positions taken by the Home Office on what counts as a good reason or a qualifying previous application are unchanged. The cite has moved; the doctrine has not.

SUI 13.1 sits inside Part Suitability of the Immigration Rules and provides, in substance, that an applicant will not be treated as an overstayer in five distinct sets of circumstances. The five sit at sub-paragraphs (a) to (e), and each is a discrete provision rather than a variant of a single rule.

SUI 13.1(a) — the first limb. An application made within fourteen days of the applicant’s previous permission expiring, where the Secretary of State considers there was a good reason beyond the control of the applicant or their representative, provided in or with the application, for the application not being made in time. This is the substantive successor of paragraph 39E(1).

SUI 13.1(b) — the second limb. An application made following the refusal or rejection of a previous application, within fourteen days of one of four triggering events: the refusal or rejection itself; the expiry of any leave extended by section 3C of the Immigration Act 1971; the expiry of the time limit for making an in-time administrative review or appeal; or the conclusion, withdrawal, abandonment, or lapse of any such administrative review or appeal. This is the substantive successor of paragraph 39E(2).

SUI 13.1(c) — a closed historical concession. Periods of overstaying that fell between 24 January 2020 and 31 August 2020, the early window of the COVID-19 pandemic during which the Home Office made a public commitment that such periods would not be held against applicants. The provision is preserved in the Rules for cases that turn on residence histories spanning that window.

SUI 13.1(d) — the Hong Kong British National (Overseas) carve-out. Periods of overstaying engaged by applicants who hold, or have held, permission on the BN(O) route, in the circumstances specified by the sub-paragraph.

SUI 13.1(e) — exceptional assurance. Periods of overstaying that fell between 1 September 2020 and 28 February 2023 and that were covered by an exceptional assurance — defined at SUI 13.2 as a written notice given to a person by the Home Office stating that they would not be considered an overstayer for the period specified. The exceptional assurance scheme was operated by the Home Office as a discretionary administrative measure during the later phases of pandemic disruption; SUI 13.1(e) is the provision that gives recognised assurance its current standing in the Rules.

The remainder of this article concerns the two principal limbs, SUI 13.1(a) and (b), which carry the substantive weight of the exception in current practice. The other three sub-paragraphs are real provisions; their operation, however, is bounded by date or by route in a way that places them outside the everyday treatment of overstayer questions.

SUI 13.1(a) provides, in substance, that the exception applies where an application for permission to stay was made within fourteen days of the applicant’s existing permission expiring, and the Secretary of State considers that there was a good reason beyond the control of the applicant or their representative, provided in or with the application, for the application not being made in time.

Four elements are doing work here. Each is a constraint.

First: the fourteen days run from the expiry of leave, not from the last day of some grace period. If leave expired on the first of the month, the outer bound of the first limb is the fifteenth. A minute past midnight on the fifteenth does not fall within it.

Second: the good reason must be “beyond the control of the applicant or their representative”. A forgotten deadline is, in ordinary English, within the control of the applicant. Unawareness of the expiry date is within the control of the applicant — a premise the Home Office applies strictly even in cases where the evidence suggests real confusion. The professional judgement of an adviser who miscalculated a date is imputed to the applicant; my lawyer got it wrong is not, on the Home Office’s current approach, a good reason.

Third: the good reason must be “provided in or with the application”. An applicant who submits an application out of time and subsequently produces an explanation in correspondence has not met the requirement that the reason accompany the application itself. The Home Office position is that the reason must be before the caseworker at the moment of decision, set out in the application or its accompanying documentation.

Fourth: the Secretary of State must “consider” that the reason is good. This is a judgement of fact, not a judgement of law, and it sits within the ordinary discretion of the decision-maker. Challenges proceed on the narrow public-law grounds that the decision was irrational, was reached on an error of law, or failed to take relevant matters into account.

Examples of what the Home Office has, in practice, accepted as good reason include serious illness of the applicant documented by contemporaneous medical records; close bereavement documented by death certificates; demonstrable postal or electronic-submission failures shown by tracking records of an application dispatched before leave expired but received after; and a small number of concessions for extraordinary external events (flood displacements, pandemic-era disruptions).

Examples of what has not, in practice, been accepted include the categories that applicants commonly assume are sufficient: personal stress, work pressure, relationship difficulties (except where they produced a documentable crisis), the adviser’s workload, unawareness of the rules, a belief that an unrelated extension was in place, a deliberate decision to wait until finances were secure.

The Court of Appeal and the Upper Tribunal have both declined to create a category of generous interpretation of the first limb. The position is that Parliament created a narrow exception, the Secretary of State applies it narrowly, and applicants who fall outside it are treated as having overstayed.

SUI 13.1(b) is the limb that most applicants and many advisers read as if it were a postscript to the first. It is not. It is, in many cases, the more important provision.

The second limb applies where an application is made following the refusal or rejection of a previous application for permission which was made in time, and within fourteen days of one of four triggering events: the refusal or rejection of that previous application; the expiry of any leave extended by section 3C of the Immigration Act 1971; the expiry of the time limit for making an in-time application for administrative review or appeal; or the conclusion, withdrawal, abandonment, or lapse of any such administrative review or appeal.

What this second limb does is structural. Section 3C of the 1971 Act continues leave automatically while an in-time application for variation is under consideration. But section 3C does not continue leave through administrative review proceedings. Administrative review is a separate post-decision process that an applicant may choose to pursue — it is available where the Immigration Rules provide for it, typically against certain refusals under the Points Based System and the family routes. During an AR the applicant is, in strict statutory terms, without leave. The leave fell away with the refusal of the underlying application.

Before the second limb was first introduced — into paragraph 39E in 2016, and now preserved at SUI 13.1(b) — this created a difficult position. The applicant who had done everything in time, whose leave had lapsed because of a refused in-time application, and who was now pursuing a formal review process, could easily become an overstayer in the eyes of a subsequent application merely by taking the review through to its conclusion. The Home Office’s general position on overstayers produced refusals in cases that on any ordinary reading ought not to have been refused.

The second limb fills that gap. It provides that an application made within fourteen days of the relevant trigger — refusal, lapse of section 3C leave, expiry of AR time limit, conclusion of AR or appeal — is treated, for the purposes of the overstayer exception, as if it were in time.

The Court of Appeal has construed this limb narrowly on the question of what constitutes a qualifying previous application. In Akinola v Secretary of State for the Home Department [2021] EWCA Civ 1308, decided under the predecessor paragraph 39E(2), the Court considered the interaction between validity, rejection, refusal, and the second limb’s prerequisite of a previous in-time application. The distinction between a refused application and a rejected application has produced its own litigation: rejection on validity grounds does not, on some readings, engage the second limb in the same way as a substantive refusal. The substance of SUI 13.1(b) is materially identical to that of paragraph 39E(2), and Akinola accordingly remains good law on the point.

This produces a pattern in which applicants who thought they were within the second limb discover that they are not, because the previous application they thought protected them was not, for the purpose of SUI 13.1(b), a qualifying application.

To understand why the exception exists in the form it does, the reader has to understand section 3C of the 1971 Act. Section 3C is the central operational feature of UK immigration practice. It provides that where an application for variation of leave is made in time — before the existing leave expires — the existing leave continues, automatically, during the determination of the application, and during any period in which an appeal could be brought or is pending. The continuation takes effect by virtue of the statute itself; it does not require the Home Office to grant it, and it cannot be withdrawn by the Home Office except by a determination of the underlying application.

Section 3C(2) lists the situations in which leave continues, including during any period when an appeal under section 82(1) of the Nationality, Immigration and Asylum Act 2002 could be brought or is pending. Section 82 of the 2002 Act lists the appealable decisions. Not every refusal of leave gives rise to a section 82 appeal — most decisions to refuse a Points Based System application, for example, generate an administrative review right rather than an appeal. Because administrative review is not an appeal under section 82, it is not covered by section 3C(2). An applicant in an AR process does not have continuing leave under section 3C.

Paragraph 39E(2), introduced into the Rules in 2016 and now preserved at SUI 13.1(b), was deliberately drawn to address the gap that this produces. The provision cannot grant leave — only the Home Office can do that. What it can do, and does, is to treat an application made within a defined post-refusal window as if it had been made in time for the purposes of the overstayer provisions. The applicant is still technically without leave during that window. They cannot work, and they cannot travel and return. What they are not doing, in the eyes of the Rules, is overstaying in a way that defeats their next application.

This is structural legal plumbing rather than a grant of indulgence. SUI 13.1 does not give applicants fourteen extra days to get their paperwork in order. It prevents the ordinary consequences of overstaying from bearing on applications that otherwise would have succeeded.

Until 11 November 2025 the overstayer exception sat at paragraph 39E in Part 1 of the Immigration Rules and the suitability grounds of refusal sat in a separate Part 9. The two interacted, often consequentially, but they were architecturally distinct. The relocation effected by HC 1333 ended that separation. SUI 13.1 now sits inside Part Suitability alongside the substantive grounds of refusal that engage when overstaying is not disregarded. The exception and the rule share a section of the Rules.

The practical effect is twofold. First, the exception is applied within the same analysis as the rest of Suitability rather than across it; a caseworker considers Suitability as a whole, and SUI 13.1 takes its place in the sequence. Second, the relationship between current and future applications is clearer. SUI 13.1 governs the treatment of the current application, and a successful invocation of it defeats refusal on overstaying grounds alone. The historic fact of having overstayed, however, persists on the Home Office record, and may engage other Suitability grounds at a later application depending on the length, the cumulative pattern, and whether a good reason was accepted at the time.

The cumulative pattern is particularly consequential. An applicant who has made two separate applications, each of which invoked the exception and each of which was saved by it, may discover on a third application that the total period of overstaying across the two earlier episodes — twenty days plus fifteen days, say — exceeds the thirty-day threshold at which the wider Suitability provisions on overstaying begin to bite. Each invocation saved its respective application; the two together may not save a third.

The fuller mechanics of Part Suitability — the thresholds, the weight given to different categories of historic conduct, the remediable and non-remediable grounds — are examined in the piece on Appendix Long Residence, where the interaction with historic conduct is most substantial. The point for the present reader is the specific one: SUI 13.1 is a provision of limited scope, operating at the moment of application, with a consequence that persists on the record beyond the application it was invoked to save.

SUI 13.1 does five things clearly, and does not do most of the things that are commonly imputed to it.

What it does:

1. It creates a fourteen-day window from the expiry of permission within which, if a good reason beyond the control of the applicant is shown, an application may be treated as in time despite the overstaying. This is SUI 13.1(a).
2. It creates a fourteen-day window from a defined list of triggering events after a refused in-time application, within which a subsequent application is similarly treated as in time. This is SUI 13.1(b).
3. It operates to prevent a refusal on overstaying grounds where the application is within either limb.
4. It operates by strict criteria applied strictly, as a matter of the Secretary of State’s discretion reviewable on public-law grounds.
5. It is a provision of the Immigration Rules, not of statute. The underlying statutory position — that overstaying triggers the ordinary consequences of being without leave, and is a criminal offence under section 24 of the 1971 Act — is not altered by it.

What it does not do:

1. It is not a fourteen-day grace period for applicants who are disorganised.
2. It does not create continuing leave during its operation. An applicant within the SUI 13.1 window is still without leave in the strict statutory sense, and cannot work or travel.
3. It does not exempt the overstaying from being taken into account on future applications. The historic fact remains on the record and may engage other Suitability grounds at a later application.
4. It does not cover every post-refusal situation. In particular, rejected applications (as distinct from refused ones), or applications that were not in time to begin with, do not engage the second limb.
5. It does not constitute advice. An applicant who is considering whether their situation falls within SUI 13.1 should not make that assessment alone.

The persistent description of paragraph 39E as the fourteen-day rule was never a mistake of ignorance. It was a habit of compression that even practitioners occasionally fell into when explaining the provision to a client. The relocation to SUI 13.1 has not, on the evidence of the past six months, broken the habit. The shorthand has simply transferred to the new home. It remains unhelpful, for the same reasons: it implies a temporal generosity that the rule does not contain, and it obscures the structural work that the second limb does in the section 3C and administrative review architecture of UK immigration.

A more accurate short description, if one is needed, would be: the overstayer-exception provision, in two limbs — one for narrow cases of good reason, one for the post-refusal continuation window that section 3C does not cover. That is not a phrase that fits in casual conversation. Perhaps it is not supposed to.

For applicants whose permission is approaching expiry, or who have already had a refused in-time application and are considering a further step, the correct next action is not to rely on a first-reading of SUI 13.1. The provision rewards applicants who have read it carefully and, where relevant, have had an adviser read it with them. It does not reward applicants who read the popular description and relied on it.
