How to Appeal an HMRC Tax Credit Decision?

Updated: Jan 27


Understanding HMRC Tax Credits and Overpayment Disputes


Introduction to HMRC Tax Credits

Tax credits in the UK, managed by Her Majesty's Revenue and Customs (HMRC), are state benefits that provide extra income to those with children and workers on lower incomes. Two main types of tax credits exist: Child Tax Credit, supporting families with children, and Working Tax Credit, for those on low incomes. Understanding the specifics of these credits is crucial for UK taxpayers, as they can significantly affect one's financial situation.


How to Appeal an HMRC Tax Credit Decision

Overpayments and Common Issues

Occasionally, HMRC may pay more tax credits than one is entitled to, known as overpayments. These overpayments can occur due to various reasons like changes in income or family circumstances, errors in information provided by the claimant, or HMRC errors. When overpayments happen, HMRC usually seeks to recover the excess amount, which can lead to financial difficulties for the recipients.


Disputing Overpayments

If you believe that an overpayment has occurred through no fault of your own, or due to HMRC's mistake, you have the right to dispute the overpayment. Disputing involves communicating with HMRC to explain why you think the overpayment should not be repaid. It is important to provide clear reasons for the dispute, including any evidence of HMRC mistakes or incorrect advice. The process begins by filling out the TC846 form, available online or in a printable format for postal submissions.


Preparing for Dispute

Before starting the dispute process, it's advisable to read up on tax credits, appeals, and complaints guidelines available on the HMRC website. Essential information needed for the form includes reasons for disputing the overpayment, your National Insurance number, and relevant details about your claim. It's important to gather all necessary documents and information before starting the process, as partially completed forms cannot be saved when filling out online.


Online and Postal Applications

The dispute can be made online, which requires a Government Gateway user ID and password, or via post. Online submissions provide a reference number for tracking the progress of your dispute. For postal submissions, it's crucial to ensure that the form is fully completed before sending it, as incomplete forms may lead to delays in the process.

Official Error and Late Appeals

In some cases, HMRC may admit to an official error, leading to a straightforward correction of the decision without a formal appeal. Such errors can be corrected up to five years from the date the decision was made, provided the claimant did not contribute to the mistake. If the deadline for appeal has passed, you might still be able to appeal under certain circumstances, such as serious illness or postal delays, within 13 months of the mandatory reconsideration notice.


Seeking Advice

While the tribunal process for appeals is less formal than court proceedings, it is advisable to seek legal or professional advice when preparing your case. This can include help with filling out forms, understanding documents, and representing you at a hearing if needed. Organisations like Citizens Advice can provide such support throughout the process.


Importance for Taxpayers

For UK taxpayers, understanding the process of disputing tax credit overpayments is critical. It empowers them to challenge decisions that may have been made in error and to mitigate the financial impact of such overpayments. With the right information and support, taxpayers can navigate the dispute process more effectively, ensuring their rights are upheld and their financial interests are protected.


The Appeal Process for HMRC Tax Credit Decisions


The Mandatory Reconsideration Phase

When disputing an HMRC tax credit decision, the first step is to request a mandatory reconsideration. This step is essential before you can appeal to a tribunal. In this phase, you must ask HMRC to review their decision, providing reasons and any additional evidence to support your case. The HMRC reviewer, independent of the original decision-maker, will re-evaluate the case and make a decision, typically within 45 days. The reviewer may either agree with you, partially agree and vary the decision, or uphold HMRC’s original decision.


HMRC's Review Outcome

If the reviewer agrees with your dispute, the original decision is canceled. If they partially agree, they will adjust the decision accordingly. However, if they uphold the original decision, you have the option to appeal to the tribunal. It's important to provide as much relevant information and evidence as possible when requesting a review to strengthen your case.


Opting for an Appeal

If you disagree with the outcome of the mandatory reconsideration or if HMRC fails to make a decision within the stipulated time, you can proceed to appeal to the tribunal. An appeal must be filed within 30 days from the date of the review conclusion letter or the expiry of the review period. This step involves submitting an appeal to the HM Courts and Tribunals Service (HMCTS), using the appropriate form or a written letter. The appeal should include your full name, National Insurance number, and the date on the mandatory reconsideration notice.


Tribunal Process

The tribunal, independent of HMRC and overseen by a judge, will examine the evidence from both parties. The judge will then make a decision based on the merits of the case. Hearings may be conducted in person, over the phone, or via video conference. In-person hearings require adherence to specific protocols like wearing a mask.


Preparing for the Tribunal

Preparation for the tribunal is crucial. This may include filling in the appeal form, understanding documents sent by HMRC or the tribunal, and organizing evidence. It is advisable to seek help from advisory services such as Citizens Advice throughout the appeal process. They can assist in understanding and responding to correspondence, preparing for the hearing, and even representing you at the tribunal.


Special Considerations and Deadlines

If you miss the deadline for filing an appeal, you might still be able to appeal under certain conditions, like serious family illness or postal delays. However, these appeals must be made within 13 months from the date of the mandatory reconsideration notice. In such cases, the tribunal will decide whether to accept the late appeal based on the circumstances.


The Importance of Legal Aid

While usually, legal aid is not available for tax credits appeals, getting professional advice is recommended. The complexity of tax laws and tribunal procedures makes it beneficial to seek expert guidance, ensuring that your case is presented effectively and your rights are fully represented.


Navigating the appeal process for HMRC tax credit decisions can be complex and daunting. Understanding each step, from mandatory reconsideration to tribunal appeal, and seeking professional help when needed, can significantly impact the outcome. For UK taxpayers facing such challenges, being informed and prepared is key to successfully resolving disputes with HMRC.

The Role of HMRC WTC/AP Form in Appealing an HMRC Tax Credit Decision

Understanding the HMRC WTC/AP Form

The HMRC WTC/AP form is a critical document for taxpayers in the UK seeking to challenge decisions regarding their tax credits. This form, formally known as the HM Revenue and Customs Working Tax Credit Appeal Form, serves as the primary means for individuals to register their disagreement with a tax credit decision made by HMRC. It's essential for those affected to understand not only the form itself but also the process it initiates and its importance in the broader context of tax administration and taxpayer rights.

Filing an Appeal: The Process and Requirements

The process of filing an appeal using the WTC/AP form is designed to be user-friendly yet thorough. When a taxpayer disagrees with a decision about their tax credits, they must first request a mandatory reconsideration from HMRC. If this reconsideration does not resolve the issue to their satisfaction, they can then proceed to file an appeal using the WTC/AP form.

This form requires detailed information about the taxpayer, the decision being appealed, and the reasons for the appeal. It's vital for taxpayers to provide clear and comprehensive reasons for their disagreement, as this information forms the basis of the appeals process. Additionally, the form asks for any supporting evidence the taxpayer wishes to submit, reinforcing the need for thorough documentation and record-keeping in matters of tax credit administration.

Timelines and Deadlines: Navigating the Administrative Process

Timeliness is a crucial aspect of the appeals process. Taxpayers typically have one month from the date of the mandatory reconsideration decision to submit their WTC/AP form. However, under certain circumstances, late appeals can be accepted if the taxpayer provides a reasonable explanation for the delay. Understanding these timelines is vital for ensuring that the right to appeal is not forfeited due to administrative oversight.

Impact of the Appeal on Tax Credit Payments

While an appeal is being considered, the original decision of HMRC generally stands. This means that any adjustments to tax credits made by HMRC will remain in effect until the appeal is resolved. Taxpayers need to be prepared for the financial implications of this, particularly if they are reliant on tax credits for their income. In some cases, interim payments may be available, but these are not guaranteed and depend on the specific circumstances of the case.

The Role of Tribunals in the Appeal Process

Once the WTC/AP form is submitted, the appeal is typically heard by an independent tribunal. This tribunal is not part of HMRC; instead, it operates under the jurisdiction of the Courts and Tribunals Service. The tribunal examines the evidence presented by both the taxpayer and HMRC, offering an impartial judgment on the matter. The role of the tribunal is crucial in ensuring fairness and objectivity in the appeals process, providing a check on the administrative decisions of HMRC.

Case Outcomes and Their Implications

The outcomes of appeals can vary widely, ranging from the tribunal upholding HMRC's original decision to a complete overturning of that decision. In some cases, the tribunal may also send the case back to HMRC for further consideration. Understanding the potential outcomes and their implications is important for taxpayers as they navigate the appeals process.

After the Tribunal: Next Steps and Further Appeals

In the event of an unfavorable decision from the tribunal, taxpayers have further recourse. They can appeal to the Upper Tribunal if they believe there has been a legal error in the decision-making process. However, this step requires careful consideration, as it involves more complex legal arguments and procedures.

The HMRC WTC/AP form is a vital instrument in the landscape of UK tax administration, providing taxpayers with a formal avenue to challenge decisions about their tax credits. Its role extends beyond mere administrative function; it embodies the principles of fairness, transparency, and taxpayer rights within the tax system. Navigating the appeals process requires a clear understanding of the form, its requirements, and the broader procedural context in which it operates. For taxpayers in the UK, the WTC/AP form is not just a document but a gateway to justice in matters of tax credit administration.

HMRC Tax Credit Appeal Form (TC846) - Navigating the Process


Introduction to the HMRC Tax Credit Appeal Form (TC846)

The HMRC Tax Credit Appeal Form (TC846) is a crucial document for UK taxpayers who wish to dispute an overpayment decision by HMRC. It is used to tell HMRC if you have received excess tax credits and believe you should not have to repay them due to HMRC's mistake or incorrect advice. The form was last updated in April 2023 for the 2023 to 2024 tax year.


Preparing for the Appeal

Before filling out the TC846 form, it’s recommended to read the 'Tax credits: appeals and complaints' guide to ensure a proper understanding of the dispute process. Necessary information for completing the form includes the reason for disputing the overpayment, your National Insurance number, and, if applicable, your partner’s National Insurance number for joint claims.


Online and Postal Submission Options

The TC846 form can be submitted online using a Government Gateway user ID and password or by post if you’re an agent or cannot use the online form. When filling out the form online, you'll receive a reference number to track the progress of your form. If submitting by post, ensure the form is completely filled out before printing and mailing it, as partially completed forms cannot be saved.


The SSCS5 Form for Tribunal Appeals

If the dispute progresses to a tribunal appeal, a different form, the SSCS5, is required. This form is not available for online submission and must be downloaded, filled out in black ink using BLOCK CAPITALS, and posted. Sections 1, 2, 5, 6, 6a, and 9 are mandatory for everyone. The SSCS5 form requires details like your personal information, the date of your mandatory reconsideration letter, and reasons if your appeal is late.


Important Considerations for the Appeal Process

  • Suspension of Debt Recovery: Upon submitting a mandatory reconsideration request, HMRC should suspend the recovery of the debt until the appeal is settled, withdrawn, or heard by a Tribunal. If you are disputing rather than appealing, the recovery will not be suspended.

  • Tribunal Hearings: If a tribunal hearing is required, it might be suggested as a phone call or video conference. Tribunal hearings are independent of HMRC and overseen by a judge who reviews evidence from both parties before making a decision.

  • Late Appeals: If you miss the deadline for appealing, you might still be able to appeal if you have a good reason, such as illness or bereavement. Late appeals must be made within 13 months from the date of the mandatory reconsideration notice.


Navigating the HMRC tax credit appeal process requires attention to detail and a thorough understanding of the necessary forms and procedures. Whether disputing an overpayment or appealing to a tribunal, the TC846 and SSCS5 forms are integral to the process. It’s advisable to seek professional advice if needed, ensuring that your appeal is as robust and well-prepared as possible. With careful preparation and understanding of the appeal process, taxpayers can effectively manage disputes with HMRC regarding tax credits.

The Role of HMRC TC846 Form in Appealing an HMRC Tax Credit Decision

Overview of HMRC TC846 Form

The HMRC TC846 form plays a pivotal role in the tax credit appeal process in the United Kingdom. It serves as a formal request for reconsideration of a decision made by HM Revenue and Customs (HMRC) regarding tax credits. This form is integral for taxpayers who believe that the HMRC has made an error in their tax credit calculation or decision.

Purpose and Significance

The primary purpose of the TC846 form is to provide a structured means for taxpayers to present their case against HMRC's decision. It ensures that all necessary details are gathered in a systematic manner, facilitating a thorough review of the decision. This form is significant as it represents the first formal step in the appeals process, offering taxpayers an avenue to seek redress.

Filling Out the Form: Key Sections

The form comprises several sections, each designed to capture specific information about the taxpayer's situation. These include personal details, the specific decision being appealed, and the reasons for disagreement. Accurately completing these sections is crucial for a successful appeal.

Reasons for Disagreement

One of the most critical parts of the TC846 form is the section where taxpayers outline their reasons for disagreeing with HMRC's decision. This requires a clear and detailed explanation, backed by any relevant evidence. This section is the taxpayer's opportunity to present their case and argue why the decision should be reconsidered.

Evidence Submission

The form allows taxpayers to attach evidence supporting their case. This could include financial statements, correspondence with HMRC, or other relevant documents. Submitting robust evidence is key to strengthening the appeal.

Timelines and Deadlines

Timeliness is essential when submitting the TC846 form. There are strict deadlines for submitting an appeal, usually within 30 days of receiving the HMRC decision. Late submissions can be accepted under exceptional circumstances, but this is not guaranteed.

HMRC's Review Process

After submission, HMRC reviews the appeal. This process involves examining the reasons and evidence provided, with the potential for additional inquiries or requests for further information.

Possible Outcomes

The outcomes of using the TC846 form can vary. HMRC may uphold their original decision, revise the decision in favor of the taxpayer, or request further information. The taxpayer is informed of the outcome and given guidance on subsequent steps if they remain dissatisfied.

Further Appeals

If the taxpayer is not satisfied with the outcome of the TC846 appeal, they can escalate the matter to an independent tribunal. This step is considered if there are grounds to believe that HMRC's decision is flawed on legal or factual grounds.


The HMRC TC846 form is a vital tool in the UK tax system, providing a structured and formal means for taxpayers to challenge tax credit decisions. Its role extends beyond administrative functionality; it represents a fundamental aspect of taxpayer rights and fair tax administration. Accurate completion and timely submission of the form, along with the provision of strong evidence, are key to effectively utilizing this tool in the tax credit appeal process.

When To Use HMRC WTC/AP Form and When To Use HMRC TC846 Form in Appealing an HMRC Tax Credit Decision In The UK - Why 2 Different Forms

The HMRC WTC/AP form and the HMRC TC846 form are used for different stages in appealing a UK tax credit decision. The WTC/AP form is typically used for the initial stage of appealing against a tax credit decision. It's the form you would fill out when you first disagree with HMRC's decision about your tax credits. On the other hand, the TC846 form is used for requesting a reconsideration, which is a step that usually follows after you have received a response to your initial appeal. It's a secondary step if you're not satisfied with the outcome of the initial appeal. Having two different forms helps streamline the process, ensuring each stage of the appeal is handled appropriately.

In the United Kingdom, navigating the process of appealing a tax credit decision involves understanding the specific roles and applications of two distinct forms provided by HM Revenue and Customs (HMRC): the WTC/AP form and the TC846 form. These forms serve different functions in the appeal process, and their use is guided by the specific circumstances and stages of the appeal.

Understanding the WTC/AP Form

The HMRC WTC/AP form, also known as the Working Tax Credit Appeal Form, is primarily used when an individual disagrees with a decision made by HMRC regarding their tax credits. This form is the first step in the formal appeals process. It is designed for taxpayers who wish to contest HMRC's decision on various grounds, including the calculation of tax credits, eligibility decisions, or other related issues.

Key Features of the WTC/AP Form

  • Initiation of the Appeal: The WTC/AP form is used to initiate the formal appeal process. It is the primary tool for taxpayers to express their disagreement with HMRC's initial decision.

  • Detailed Explanation Required: The form requires a detailed explanation of why the taxpayer believes the decision is incorrect, including any relevant circumstances or evidence.

  • Timeliness: Timely submission of this form is crucial. Typically, there is a deadline (usually 30 days from the HMRC decision) within which the appeal must be lodged.

Understanding the TC846 Form

The TC846 form, on the other hand, is used for a different stage in the appeal process. This form is typically utilized when a taxpayer requests a reconsideration of HMRC's decision following an initial response to their appeal.

Key Features of the TC846 Form

  • Request for Reconsideration: The TC846 form is used when a taxpayer is dissatisfied with the outcome of their initial appeal or wishes to challenge HMRC's response.

  • Second Stage of Appeal: It represents a secondary stage in the appeals process, offering another level of review.

  • Further Explanation and Evidence: This form allows taxpayers to provide additional information or evidence that might not have been included in the initial appeal.

Why Two Different Forms?

The existence of two separate forms – WTC/AP and TC846 – reflects the layered approach to appeals in the UK tax system. This structure ensures that taxpayers have multiple opportunities to present their case and have it reviewed at different levels.

  • Clarity and Structure: Having distinct forms for different stages of the appeal process brings clarity and structure to what can be a complex procedure. It helps in organizing the process and ensures that taxpayers understand at which stage they are engaging with HMRC.

  • Efficient Processing: By segmenting the appeals process into initial appeals and reconsiderations, HMRC can manage and process appeals more efficiently. This differentiation aids in the administrative handling of numerous appeals.

  • Fairness and Rigour: The two forms allow for a more rigorous and fair examination of appeals. Taxpayers have the opportunity to refine their arguments or present new evidence at the reconsideration stage, which might not have been possible in the initial appeal.

In summary, the WTC/AP and TC846 forms are integral components of the UK's tax credit appeal process, each serving a specific purpose. The WTC/AP form is the starting point for challenging an HMRC decision, while the TC846 form offers a subsequent avenue for further review and reconsideration. This system, with its distinct stages and corresponding forms, exemplifies the commitment to a thorough, fair, and structured approach to tax credit appeals in the UK. It underscores the importance of understanding and correctly utilizing these forms to effectively navigate the appeal process.

The Role of HMRC SSCS5 Form in Appealing a Tax Credit Decision - Why Yet another 3rd Form?

The HMRC SSCS5 form plays a crucial role in the further escalation of appeals in the UK tax credit system, especially after the initial steps involving the HMRC WTC/AP and TC846 forms have been completed. This form is specifically used for appealing to the Social Security and Child Support Tribunal after previous appeals to HMRC have not resolved the taxpayer's concerns.

The necessity of the SSCS5 form arises when a taxpayer is not satisfied with the outcomes from using the WTC/AP and TC846 forms. This situation typically occurs when the taxpayer believes there has been a misinterpretation of the law, overlooked evidence, or an error in the administrative process. The SSCS5 form allows for an independent tribunal to review the case, providing an additional layer of scrutiny and fairness.

Moreover, the SSCS5 form may be required in complex cases where there are broader implications or where the taxpayer feels that the decision-making process has not adequately considered their circumstances. This form offers a more formal and legally structured avenue for appeal, involving legal representatives and potentially leading to a tribunal hearing.

Initial Steps: HMRC WTC/AP and TC846 Forms

The appeal process for tax credit decisions in the UK begins with the HMRC WTC/AP form. This form is used for an initial appeal against a decision by HMRC. If dissatisfied with the outcome, the taxpayer proceeds to the TC846 form, which requests a reconsideration of HMRC's decision.

The Need for SSCS5 Form

Following these initial stages, if the taxpayer remains unsatisfied, the HMRC SSCS5 form becomes necessary. This form escalates the appeal to an independent tribunal, offering a higher level of scrutiny.

Filing an SSCS5 Appeal

The SSCS5 form is filed with the Social Security and Child Support Tribunal. This step is taken when there are grounds to believe that the previous decisions were incorrect due to legal errors, overlooked evidence, or procedural issues.

The Tribunal Process

The tribunal, an independent body, reviews the case, providing a fresh perspective and ensuring a fair hearing. This stage may involve legal arguments and representation.

Conclusion: The Role of SSCS5 in the Tax Credit Appeals Process

The HMRC SSCS5 form is essential in providing taxpayers with an avenue for external review beyond the HMRC's internal processes. It highlights the UK tax system's commitment to thorough, impartial adjudication in tax credit matters.

How to Fill SSCS5 form - A Step-by-Step Process

The SSCS5 form is used for appealing against decisions made by HM Revenue and Customs (HMRC) regarding various benefits such as Tax Credit, Child Benefit, Guardian’s Allowance, and others. The form has multiple sections, each requiring specific information from the appellant.

This section requires basic personal information like name, address, date of birth, National Insurance number, and contact details. You should provide accurate and current information to ensure effective communication regarding your appeal.

Section 2: Benefit Appeal Details

Here, you specify which benefit your appeal is about. It's important to be precise, as the benefit type can affect the appeal process.

Section 3: Appointee Information (If Applicable)

If someone is appointed by HMRC or a court to handle the benefits of another person, their details go in this section.

Section 4: Representative Details

If you have a representative to help with your appeal, their details are filled in here. This can be a legal advisor, friend, or family member.

Section 5: Reasons for Appeal

This crucial section is where you articulate the reasons for your appeal. Be clear and detailed about why you disagree with HMRC's decision. Providing evidence to support your claims is also critical.

Section 6: Appeal Hearing

Indicate whether you wish to be part of the hearing process and, if so, your preferred mode of hearing (telephone, video, or face-to-face).

Section 7: Support at Hearing

If you require any special support during the hearing, like an interpreter or accessible facilities, mention it in this section.

Section 8: Availability for Hearing

Specify any dates when you are not available for the hearing. This helps in scheduling the hearing at a convenient time.

Section 9: Signature and Submission

Finally, sign the form, confirming that the information provided is accurate. You also need to submit the form to the appropriate address, along with a copy of the Mandatory Reconsideration Notice (MRN).

Tips for Filling Out the Form:

  • Use black ink and BLOCK CAPITALS where instructed.

  • Be thorough and provide as much detail as possible, especially in the reasons for appeal.

How Can a Tax Accountant Help with HMRC Tax Credit Appeals

How Can a Tax Accountant Help with HMRC Tax Credit Appeals?

Navigating the complexities of tax credit appeals with HM Revenue and Customs (HMRC) can be daunting for taxpayers. This is where the expertise of a tax accountant becomes invaluable. Tax accountants play a crucial role in guiding individuals through the HMRC tax credit appeal process, ensuring that their clients' cases are presented accurately and effectively. Their knowledge and experience can be a deciding factor in the success of an appeal.


Understanding Tax Credits and HMRC Appeals

Tax credits, such as Child Tax Credit and Working Tax Credit, are benefits designed to support individuals with children or those on low incomes. However, issues like overpayments and eligibility disputes can arise, leading to the need for appeals to HMRC. A tax accountant can demystify the often complex criteria and regulations surrounding tax credits, helping clients understand their entitlements and the reasons behind HMRC's decisions.


Expert Analysis of HMRC Decisions

One of the first steps a tax accountant takes is a thorough analysis of HMRC's decision regarding tax credits. They review the client's case, cross-checking with the latest tax laws and regulations. This expertise allows them to identify any errors or misinterpretations in the initial assessment by HMRC, forming a solid foundation for an appeal.


Assistance with Mandatory Reconsideration

Before appealing to a tribunal, taxpayers must ask HMRC for a mandatory reconsideration. A tax accountant assists in drafting a comprehensive reconsideration request, incorporating all necessary evidence and articulating why the decision should be reviewed. Their skill in presenting the case in a clear, concise, and legally sound manner significantly enhances the chances of a favorable outcome at this stage.


Guidance Through the Appeal Process

If the case progresses to a tribunal, a tax accountant’s role becomes even more crucial. They guide their clients through the preparation of the appeal, including the completion of the necessary forms (such as the SSCS5 form) and gathering of supporting documentation. Their knowledge of the tribunal's procedures and requirements ensures that the appeal is procedurally correct and substantively strong.


Representation and Advocacy

In some cases, tax accountants can represent their clients in dealings with HMRC or even at tribunal hearings. Their advocacy skills, coupled with their tax expertise, can be instrumental in effectively communicating the intricacies of a case. They can challenge HMRC’s position with well-researched arguments, increasing the likelihood of a successful appeal.


Providing Strategic Advice

Tax accountants also offer strategic advice on the potential risks and benefits of pursuing an appeal. They can advise on the likelihood of success and the possible financial implications, helping clients make informed decisions. This strategic counsel is particularly important in cases where an appeal could potentially lead to increased liabilities.


Ensuring Compliance and Future Advice

Following the resolution of an appeal, a tax accountant plays a key role in ensuring ongoing compliance with tax credit rules. They can provide advice on how to avoid future issues with HMRC, including accurate reporting of changes in circumstances and understanding of entitlement criteria.


Emotional and Practical Support

Dealing with HMRC can be stressful for taxpayers. A tax accountant provides not only technical support but also emotional reassurance throughout the process. They handle the bulk of the communication with HMRC, reducing the client's burden and stress.


A tax accountant's expertise is invaluable in navigating the HMRC tax credit appeal process. From analyzing HMRC decisions and guiding mandatory reconsiderations to representing clients in tribunals, their role is multifaceted.
