Cassation Appeal Against Civil Judgments
A cassation appeal is an extraordinary method of objecting to court judgments. The authority competent to examine such appeals is the Supreme Court.
Judgments Subject to Cassation and Exceptions
Cassation Appeal
As stated above, a cassation appeal is an extraordinary means of challenging a court judgment, through which the contested decision is reviewed for compliance with Islamic principles and statutory laws.
The Supreme Court examines the cassation petition and, by either affirming or overturning the challenged judgment, fulfills its duty of supervising the proper and uniform application of the law.
In handling cassation appeals, the Supreme Court either affirms the contested judgment or annuls it and remits the case to the court of first instance or to a parallel branch. This is because reexamination of the merits of the dispute does not fall within the Supreme Court’s jurisdiction. Rather, its review is limited to whether the judgment issued conforms to legal and religious standards.
This distinction explains the difference between cassation, appeal, and objection proceedings. In appellate review, the appellate court reassesses the case in its entirety and may even issue a new judgment that contradicts the prior decision.
Judgments Subject to Cassation
As a general legal principle, judgments issued by courts become final at the appellate stage and are no longer subject to further objection. However, in certain civil matters and claims, depending on whether the judgment was issued by a court of appeal or a court of first instance, cassation review is provided by law. These judgments include the following:
Judgments Issued by Courts of Appeal
Judgments concerning the essence or dissolution of marriage, lineage, divorce, endowment, or legal incapacity are subject to cassation review.
Exceptions:
- Where the judgment is based on a decisive admission by one of the parties.
- Where the judgment is based on an expert opinion that the parties have expressly and in writing agreed to treat as decisive.
- Where the parties have expressly waived their right to file a cassation appeal.
Orders issued by courts of appeal, such as orders rejecting a claim, invalidating a petition, declaring the lapse of a claim, or determining the lack of legal capacity of one of the parties, are subject to cassation only if the underlying judgment itself is eligible for cassation review.
Judgments of Courts of First Instance Subject to Cassation
Pursuant to the Civil Procedure Code, certain judgments issued by courts of first instance are also subject to cassation review, provided that such judgments have become final and have not been challenged through objection or appeal.
These judgments include:
- Judgments involving claims exceeding twenty million rials.
- Judgments relating to the essence or dissolution of marriage, lineage, divorce, legal incapacity, detention, trusteeship, one-third estate disposition, and endowment.
Orders issued by courts of first instance, including orders declaring the lapse of a claim, lack of legal capacity of a party, rejection of a petition, or invalidation of a petition, are subject to cassation review only where the underlying claim itself is eligible for cassation.
Incidental Cassation Appeal
Under the Civil Procedure Code, another form of cassation appeal is the incidental cassation appeal. This type of appeal may only be filed by the respondent to the cassation appeal against the appellant and must be raised within the response submitted to the cassation petition.
Time Limit for Filing a Cassation Appeal
For individuals residing in Iran, the time limit to file a cassation appeal is 20 days from the date of notification. For individuals residing outside Iran, the time limit is two months from the date of notification of the judgment. If the appellant has a legitimate excuse for delay, supporting documents and evidence must be submitted together with the cassation brief.
Procedure and Stages of Cassation Appeal
A cassation appeal must be filed through the electronic judicial service offices. The appellant is required to prepare and submit a cassation petition along with a cassation brief through these offices. After completion of this process, the petition is forwarded to the court that issued the challenged judgment, and a copy of the petition and brief is served on the respondent.
The respondent is granted a twenty-day period to submit a written response to the appellant’s arguments to the issuing court. Subsequently, the case file is referred to a Supreme Court chamber for review.
Frequently Asked Questions Regarding Cassation Appeals Against Civil Judgments
A cassation appeal is an extraordinary method of objecting to a court judgment that is examined by the Supreme Court. The Supreme Court reviews only the compliance of the judgment with the law and Islamic principles and does not consider the merits of the dispute. In contrast, on appeal, the appellate court reexamines the case and may issue a new judgment that differs from the prior one.
Judgments relating to the essence or dissolution of marriage, lineage, divorce, endowment, and legal incapacity issued by courts of appeal are subject to cassation, unless they are based on a decisive admission, a written agreement accepting an expert opinion as final, or a waiver of the right to cassation.
Judgments involving claims exceeding twenty million rials, as well as judgments concerning marriage, dissolution of marriage, lineage, divorce, legal incapacity, detention, trusteeship, one-third estate disposition, and endowment, are subject to cassation provided that they have become final and have not been challenged through objection or appeal.
An incidental cassation appeal arises when the respondent to a cassation appeal, in responding to the appellant’s brief, submits a cassation request against the appellant. This is permissible only within the context of the respondent’s reply.
The time limit is twenty days from the date of notification for residents of Iran and two months for residents outside Iran. In the event of a justified delay, supporting documentation must be attached to the cassation submission.
A cassation appeal is filed through electronic judicial service offices. The appellant must submit the cassation petition and brief, after which the documents are forwarded to the issuing court and served on the respondent.

If someone misses the appeal deadline by just a few days because of an emergency, are there ever exceptions?
Whether a late appeal can still be considered depends on the applicable procedural rules and the reason for the delay. Some legal systems recognize limited exceptions in specific circumstances, but these are generally subject to strict legal requirements. It is important to act promptly whenever an appeal is being considered.
Can both parties appeal the same judgment at the same time?
Yes. If each party believes that the judgment adversely affects its rights or interests, both may have the right to file an appeal in accordance with the applicable procedural law. The appellate court will then consider the issues properly raised by each side.
Does filing an appeal automatically stop the judgment from being enforced?
Not always. Whether enforcement is suspended during the appeal depends on the applicable law and the nature of the judgment. In some cases, additional legal steps may be required to postpone enforcement while the appeal is pending.
Can new evidence be submitted during the appeal, or is the court limited to the original case file?
That depends on the procedural rules governing the appeal. Some appellate courts may consider new evidence under specific conditions, while others primarily review the legal and factual findings made by the lower court.
If only one part of the judgment is disputed, does the entire case have to be appealed?
Not necessarily. An appeal may be limited to the specific parts of a judgment that the appellant believes are incorrect. The scope of appellate review generally depends on the issues raised in the appeal and the applicable procedural rules.
Can the appellate court reach the same result but for completely different legal reasons?
Yes, depending on the applicable legal framework. An appellate court may uphold a judgment while relying on different legal reasoning if it concludes that the final outcome is legally correct.
Is an appeal a completely new trial with witnesses appearing again?
Not usually. In many legal systems, an appeal focuses on reviewing the lower court’s judgment rather than conducting an entirely new trial. Whether witnesses are heard again depends on the type of appeal and the governing procedural rules.
Can someone withdraw an appeal after filing it?
In many situations, yes. An appellant may be permitted to withdraw an appeal, although the procedure and legal consequences depend on the applicable procedural rules and the stage of the proceedings.
If the appellate court finds only a minor legal error, does that always mean the judgment will be overturned?
No. Not every legal error necessarily results in the judgment being reversed. The appellate court generally considers whether the error materially affected the outcome before deciding whether to uphold, modify, or set aside the judgment.
What’s one mistake people commonly make when deciding whether to appeal?
A common mistake is assuming that simply disagreeing with the outcome is enough to succeed on appeal. Appellate courts generally examine whether there are valid legal or procedural grounds to challenge the judgment, rather than reconsidering every aspect of the case from the beginning. Preparing well-supported grounds of appeal is often just as important as filing the appeal on time.
