Appeal and Cassation in a Criminal Case: Real Chances of Challenging a Sentence and How It Works

10.06.2026Reading time: 8 minAuthor: attorney Yuriy Arutyunov

A sentence handed down by a court of first instance does not always become the final decision in a criminal case. The Code of Criminal Procedure of the Russian Federation provides for several stages of appeal that make it possible to correct errors made during the investigation or during the trial. Appeal and cassation in a criminal case give the convicted person, their defence counsel or the victim an opportunity to have the decision reviewed. In Moscow, such appeals are heard by the Moscow City Court, and at the next levels by higher courts.

Many people find themselves in a situation where a sentence seems too harsh or contains violations. Under Article 389.1 of the Code of Criminal Procedure of the Russian Federation, an appeal makes it possible to review the lawfulness and validity of a sentence before it enters into force. This is an important mechanism for protecting rights that helps avoid unjust punishment. An attorney for criminal cases in Moscow with experience in appellate courts helps to build the right strategy for an appeal.

The difference between appeal, cassation and supervisory review

Appealing a sentence in a criminal case

An appeal is a review of a sentence conducted under rules close to those governing the hearing of a case at first instance. The court of appeal re-examines the evidence, questions witnesses where necessary and assesses whether the rules of criminal and criminal procedure law were correctly applied. A sentence may be appealed within 10 days of the day it is pronounced or handed to the convicted person.

On appeal, new evidence may be submitted if it became known after the sentence was passed or, for valid reasons, was not examined earlier. For example, if a new expert examination has become available or a witness has appeared who previously could not give evidence. An attorney handling an appeal in a criminal case carefully prepares the appeal, pointing to specific violations, such as incorrect classification under an article of the Criminal Code or a discrepancy between the court's conclusions and the actual circumstances.

Cassation in a criminal case: features and procedure

A cassation appeal begins after the sentence has entered into legal force. Under Chapter 47.1 of the Code of Criminal Procedure of the Russian Federation, cassation reviews material violations of criminal procedure law that affected the outcome of the case. Here the evidence is no longer reassessed; instead, gross errors are sought: for example, a case being heard by an unlawfully constituted court, a violation of the right to a defence, or incorrect application of substantive law.

The time limit for filing a cassation appeal is three months. A cassation appeal in a criminal case requires an in-depth analysis of the case materials and references to resolutions of the Plenum of the Supreme Court of the Russian Federation. In Moscow, such appeals are often sent to the judicial panel for criminal cases of the Moscow City Court, and then to the Supreme Court.

Supervisory review as an exceptional stage of review

Supervisory review is used in cases of particularly gross violations affecting citizens' constitutional rights. The Chairman of the Supreme Court or the Chairman's deputies may initiate a review. This stage is used rarely, but in complex cases it may become the last chance for justice.

Time limits for appealing a sentence and important procedural points

The time limits for appealing a sentence are strictly regulated. For an appeal, it is 10 days. Missing the deadline is permissible only for valid reasons, such as serious illness or late delivery of a copy of the sentence. For cassation, it is 3 months from the day the decision enters into force. Restoring a missed time limit requires a separate motion and supporting documents.

What can be appealed? The entire sentence or individual parts of it: the type and severity of the punishment, the classification of the offence, the decision on the civil claim. A preventive measure may be appealed both on appeal and in cassation. For example, if a person is held in custody without sufficient grounds, the attorney prepares an appeal against the extension of the detention.

  • 10 days for an appeal from the day the sentence is pronounced
  • 3 months for cassation after the sentence enters into force
  • The possibility of restoring a missed time limit for valid reasons
  • Mandatory participation of defence counsel at all stages of appeal upon a motion

Grounds for a successful appeal and cassation in criminal cases

A successful appeal under the Criminal Code is most often based on the following grounds: material violations of criminal procedure law (Article 389.15 of the Code of Criminal Procedure of the Russian Federation), incorrect application of criminal law, or the unfairness of the sentence. Typical violations include refusal to grant well-founded motions of the defence, falsification of evidence or pressure on witnesses.

An example from practice: in one case, the sentence was amended on appeal because the court of first instance had not taken into account mitigating circumstances — the presence of young children and positive character references from the place of work. As a result, the punishment was reduced from actual imprisonment to a suspended sentence. An attorney for criminal cases in Moscow uses such precedents to build a strong position.

Statistics on appeals against sentences in Moscow courts

According to judicial statistics, around 15–25% of appeals in criminal cases are granted in full or in part by the appellate instance of the Moscow City Court. In cassation, the percentage is lower — approximately 5–10%. However, with a competently prepared appeal and the participation of experienced defence counsel, the figures improve noticeably. This confirms the importance of professional legal assistance in criminal cases.

What an attorney does when preparing an appeal or a cassation appeal

An attorney for criminal cases studies all the case materials in detail: interrogation records, expert examinations, the results of operational search activities. The attorney then forms a legal position and drafts a reasoned appeal with specific references to articles of the Code of Criminal Procedure of the Russian Federation and the Criminal Code of the Russian Federation.

At the appeal hearing, the attorney files motions for the examination of new evidence, the questioning of witnesses and the exclusion of inadmissible evidence. In cassation, the emphasis is on procedural violations. An attorney's services in criminal cases include full support: from preparing documents to taking part in hearings and monitoring the enforcement of the court's decision.

The attorney's step-by-step procedure for an appeal

First, a detailed consultation and analysis of the sentence are carried out. Next, any missing case materials are requested. After that, all possible violations are identified and a strategy is formed. The text of the appeal is prepared, and additional character references and certificates are collected. Finally, the client's interests are represented in court and any objections from the opposing party are dealt with.

  • Reviewing all volumes of the criminal case
  • Identifying violations of the Code of Criminal Procedure of the Russian Federation and the Criminal Code of the Russian Federation
  • Preparing an appeal or a cassation appeal
  • Collecting additional documents and character references
  • Taking part in hearings of higher courts
  • Monitoring time limits and the correct enforcement of the decision

Typical mistakes when appealing a sentence on your own

Filing an appeal on your own often results in a refusal to accept it. The main mistakes are an emotional style of presentation instead of legal arguments, no references to specific legal provisions, missed deadlines and an incomplete set of documents. In addition, without professional analysis it is difficult to spot hidden procedural violations.

To avoid these problems, it is advisable to seek help in good time. An urgent attorney in Moscow can step in even in the last days of the time limit and minimise the risks. A good attorney in Moscow knows the specifics of how cases are heard in the capital's courts and helps to avoid formal refusals.

Real possibilities and what you can expect from an appeal

As a result of a successful appeal or cassation, a sentence may be quashed entirely and the case sent for a new hearing, or amended with a reclassification of the article or a reduction of the punishment. Sometimes the case is terminated for lack of the elements of a crime.

For example, in theft cases (Article 158 of the Criminal Code of the Russian Federation), it is often possible to obtain reclassification to a less serious article where there are mitigating circumstances. In cases involving bodily harm (Articles 111, 112 and 115 of the Criminal Code of the Russian Federation), additional medical examinations play an important role. An attorney for defence in court helps to gather such evidence and present it properly.

Other areas of an attorney's work in criminal cases

Experienced defence counsel also provides assistance in cases of driving while intoxicated, violation of traffic rules, extortion, fraud, hooliganism and other offences. Work on entering into an inheritance and personal bankruptcy is also possible as part of comprehensive protection.

How to prepare properly for appealing a sentence

Preparation begins with obtaining a copy of the sentence and the record of the court hearing. It is important to keep all documents and correspondence. You should not comment to the media or other participants without consulting your defence counsel. Every step can affect the outcome of the case in higher courts.

An attorney available around the clock in Moscow is ready to provide support in difficult situations. Legal assistance in criminal cases makes it possible to approach the problem systematically and increase the chances of a positive result on appeal or in cassation.
