1. Appeal — apellyatsiya. Filed within 15 days of the verdict. The appeal court can re-examine both the facts and the law, hear evidence again, and change the sentence. This is the widest opportunity and the shortest deadline. Details on the appeal page.
2. Cassation — kassatsiya. Once the verdict has entered into force. The cassation court does not re-establish facts; it looks for breaches of law significant enough to have affected the outcome. Filed within six months for the "continuous" route, after which the case can still be raised but only at a judge's discretion. Details on the cassation page.
3. The Supreme Court of the Russian Federation. A second level of cassation before the Judicial Collegium for Criminal Cases, and beyond it supervisory review before the Presidium. See Supreme Court appeal.
4. A complaint to the Chairman of the Supreme Court. Where a single judge has refused to refer a cassation complaint to a hearing, the Chairman or a deputy may disagree with that refusal. A narrow but real remedy — see complaint to the Chairman.
5. The Constitutional Court. Not an appeal. It examines whether the law applied in the case is compatible with the Constitution. See Constitutional Court complaint.
