The importance of the accounting expert opinion in the appeals phase of judicial and arbitral disputes
In the world of litigation, mistaken decisions do not always mean the end of the road. In many situations, errors in technical interpretation or inconsistencies in the expert reports presented in the first instance can be corrected through a well-founded accounting expert opinion during the appeals phase. This stage is decisive for supporting legal arguments in higher courts, and therefore requires a robust, clear, and technically incontestable document.
This is where DFEXA – Dispute & Forensic Experts Advisory stands out. With a highly qualified team composed of masters, doctors, and professionals with extensive forensic experience, DFEXA offers accounting, economic, and financial opinions specifically geared towards the appeals phase, providing not only technical foundations but also direct impact on judicial or arbitral case reassessment.
In this article, we explore why accounting expert opinions have gained increasing relevance in appeals, how they are used, and how they can change the course of a dispute—even after an unfavorable decision.
What is an accounting expert opinion for appeals?
An accounting expert opinion geared towards the appeals phase is a document prepared with the aim of countering, complementing, or clarifying points in expert reports presented in earlier stages of a judicial or arbitral proceeding. It is a technical instrument that allows a second, more critical and in-depth review of the elements already included in the case files, offering a new layer of analysis that may be decisive in overturning a judgment.
Unlike a pre-litigation expert report, usually produced in the pre-procedural or evidentiary stage to support petitions, the appeals opinion specifically identifies weaknesses, omissions, methodological inconsistencies, or even technical flaws in the expert documents used as a basis for the judgment or arbitral decision.
Why is it decisive in the appeals phase?
The appeals phase is often the last opportunity to reverse an unfavorable decision. However, for an appeal to be effective, it is not enough to simply express disagreement with the result. It is necessary to technically demonstrate where the errors lie and why the decision should be reviewed.
In this regard, an accounting expert opinion can:
- Reveal calculation or methodological errors in the previous report;
- Indicate that the assumptions used were not consistent with the available documentation;
- Show that economic hypotheses were not properly tested or substantiated;
- Counter misinterpretations of contractual clauses from a financial perspective;
- Identify omissions or negligence in the collection of accounting and tax data;
- Provide alternative simulations more realistic and consistent with the nature of the operation in question.
When well presented, these technical elements reinforce legal arguments and significantly increase the chances of success in an appeal or reconsideration.
Cases where a DFEXA expert opinion made a difference
Although confidentiality prevents the disclosure of specific cases, there are many examples where opinions prepared by DFEXA played a decisive role in reversing unfavorable decisions or weakening opposing theses during the appeals phase.
Among the main types of disputes in which these opinions have proven effective are:
- Corporate disputes involving equity assessments;
- Contractual conflicts with adjustment clauses, default, or financial charges;
- Debates over managerial liability and misuse of resources;
- Tax-related litigation based on assessments or disputed amounts;
- Compliance and integrity processes where decisions were based on inconsistent reports.
The differential of DFEXA’s opinions lies not only in their technical content but also in their ability to communicate clearly, logically, and structurally with the decision-maker. This makes the reading more fluid and the persuasion more natural.
Who is it for and when to request an appeals opinion
The DFEXA accounting expert opinion can be requested by:
- Law firms specialized in strategic litigation and arbitration;
- Legal departments of companies involved in complex legal disputes;
- Arbitration chambers and institutions seeking independent technical assessments;
- Boards of directors and audit committees needing support in decisions about pursuing appeals;
- Risk, compliance, and controllership managers involved in litigation loss prevention.
The best time to request the opinion is immediately after the ruling or arbitral award is published while there is still time to appeal. The sooner the opinion is prepared, the greater its chance to positively influence the appeal strategy.
