Comprehensive guide to written submissions in UK immigration appeals. Explains the purpose, structure and requirements of Appeal Skeleton Arguments, Practice Direction rules, timing and procedural steps for written submissions in First‑tier Tribunal (Immigration and Asylum Chamber) cases, with practical tips for appellants and advisers.

Written submissions - often called skeleton arguments or appeal submissions - are a central part of preparing and presenting an immigration appeal in the United Kingdom. When challenging a refusal by the Home Office in the First‑tier Tribunal (Immigration and Asylum Chamber), clear written submissions help the tribunal understand why the original decision is wrong and what legal and factual issues the appellant relies on. Written advocacy plays a vital role in influencing how the tribunal evaluates the appeal, supports evidence, and ultimately decides the case. This article explains the purpose, structure, procedural requirements, timing, practical guidance, risks and common questions about written submissions in immigration appeals.
What Are Written Submissions in an Immigration Appeal?
Written submissions in an immigration appeal are documents submitted to the tribunal that explain the appellant's legal and factual arguments in support of overturning a Home Office decision. They serve as a roadmap for the tribunal and the respondent (usually the Home Office) to understand:
- The grounds of appeal.
- The factual basis for the challenge.
- The legal principles and policies that support the appellant's position.
- Reference to evidence and law explaining why the original decision was incorrect or unreasonable.
In the context of the First‑tier Tribunal's online procedure, these submissions are normally required as an Appeal Skeleton Argument (ASA) and are provided alongside the appeal bundle of evidence.
Legal and Procedural Requirements
Appeal Skeleton Argument (ASA)
Under the tribunal's procedural rules, appellants must provide an Appeal Skeleton Argument within specified timeframes after the respondent (Home Office) has provided their bundle of documents:
- Generally 28 days after the respondent's bundle is provided, or
- 42 days after the Notice of Appeal, whichever is later.
The ASA must contain three core elements:
- Brief summary of the appellant's factual case
This outlines the key facts underpinning the appeal, such as dates, personal circumstances, and the Home Office decision being challenged. - Schedule of issues
These are the discrete points of law or fact that the appellant disputes. Listing issues clearly helps the tribunal focus on what is genuinely in dispute. - Appellant's submissions on each issue
This explains why the decision was incorrect, citing relevant law, facts and evidence. Submissions should be clear and detailed enough for the tribunal and respondent to understand the basis of challenge.
The ASA should be concise, structured in numbered paragraphs, and engage directly with the decision under challenge, without extensive quotations from large documents.
Practice Direction Requirements
A new Practice Direction governs written submissions in immigration appeals, especially in online cases. Key points include:
- Page limits: A standard ASA is limited to 12 pages unless permission is obtained to exceed this (for example, where complex issues require more detailed treatment).
- Formatting: Text must be legible (size 12 font, 1.5 line spacing).
- Issue‑based focus: Written submissions should concentrate on principal and disputed issues, without including unnecessary material.
These requirements reflect the tribunal's emphasis on clarity, efficiency and fairness in managing appeals.
Bundles and Evidence
Where the ASA refers to material not already in the Home Office bundle, the appellant must provide that material in an indexed and paginated bundle simultaneously with the ASA. This ensures all referenced evidence is readily accessible to the tribunal and the respondent.
Purpose and Strategic Role of Written Submissions
Written submissions serve multiple purposes:
- Clarify arguments for the tribunal: They frame the core legal and factual questions in the appeal, allowing judges to focus on contested points early.
- Influence tribunal directions: Well‑prepared submissions may reduce the need for a full oral hearing or shape case management directions.
- Assist the respondent's review: The Home Office must review the ASA and provide a meaningful response, indicating which issues it accepts, denies or contests.
- Support oral advocacy: A clear written summary strengthens oral submissions at the hearing by providing a structured reference point.
Because the tribunal will rely heavily on the written argument, appellants (and their advisers) should plan submissions carefully, integrating facts, legal authority and policy context.
Preparing Effective Written Submissions
Focus on Key Issues
The written submissions should identify the central issues in dispute between the appellant and the Home Office. Appellants should avoid broad repetition of facts that are not directly relevant to the legal tests in question. An issues schedule helps the tribunal isolate what matters most.
Engage with the Decision Under Challenge
Rather than repeating factual narrative, submissions should engage explicitly with the wording of the Home Office decision letter or first instance decision. This means citing specific findings or reasoning that the appellant argues is erroneous.
Use Clear, Logical Structure
Use numbered paragraphs and clear headings to guide the reader. Begin with a concise summary, followed by the schedule of issues and then a detailed explanation of each point. Legal references should be clearly linked to fact and to evidence in the bundle.
Reference Authoritative Evidence
Written submissions should make reference to supporting evidence (such as witness statements, expert reports or country information) and legal authority (statutes, policy guidance, case law). Where documents are cited, they should be readily found in the index or bundle.
Time Limits and Practical Milestones
Time limits for written submissions are strict and must be met to avoid delay or adverse case management orders:
- Deadlines for submitting the ASA are usually communicated in the tribunal's directions or via email when the respondent's bundle is uploaded.
- Parties should monitor deadlines closely and use HMCTS online systems (such as MyHMCTS) to track due dates and upload documents.
Failing to comply with directions risks the tribunal proceeding without full written argument or issuing case management orders that limit reliance on late submissions.
Written Submissions for Unrepresented Appellants
Appellants without legal representation also must provide written submissions, but the tribunal may offer procedural flexibility. If unrepresented, parties may be directed to provide a written outline of issues and evidence in a clear, accessible format that enables the Home Office and tribunal to understand the case. The Practice Direction anticipates that unrepresented appellants will still meet basic requirements for clarity and structure, albeit with directions tailored to their circumstances.
Common Challenges and Risks
Overly Long or Unfocused Submissions
Without clear structure and concise legal framing, written submissions can become unwieldy or confusing. Page limits and issue‑based focus increase efficiency but require careful editing.
Late Evidence and Submissions
Tribunals may permit late evidence or supplementary written submissions only by leave, usually justified by significant new matters or good reasons why the material was not provided earlier. Appellants should avoid last‑minute filings unless genuinely necessary and supported by application.
Failure to Link Submissions to Evidence
An argumentative skeleton without clear linkage to the evidential bundle or legal rule risks dismissal or weak impact. Written submissions should always cross‑reference page numbers, paragraph numbers and legal authority.
Common Questions
Are written submissions mandatory in every immigration appeal?
Yes, in most cases the tribunal will direct appellants to provide an Appeal Skeleton Argument or written submissions as part of the online appeal process. Failure to provide them can affect how the case is managed and decided.
Can I submit new evidence with my written submission?
Yes, but any new evidence referred to in the ASA must be included in the appellant's bundle when the submission is provided. Evidence must be indexed and clearly linked to argument.
Can the respondent (Home Office) respond in writing?
Yes. After the ASA is provided, the Home Office must conduct a meaningful review and respond in writing, indicating acceptance, denial or modification of points raised. This response helps clarify disputed issues before a hearing.
Key Takeaways
Written submissions, especially the Appeal Skeleton Argument, are a core feature of immigration appeals in the UK. They require appellants to frame their grounds of appeal in a structured, persuasive document that summarises facts, outlines key issues and explains legal submissions with reference to evidence. Timely preparation, clarity, issue‑based structure and compliance with Practice Direction requirements (such as page limits) are essential for effective advocacy. Written submissions enable both the tribunal and the Home Office to understand the contested points, guide case management, and support oral advocacy at hearings. Meeting procedural deadlines and preparing clear, concise submissions enhances the chances of a successful appeal.
