Who this page is for

This page is for a defendant who has received an unfavourable first-instance judgment in a Bulgarian criminal case and wants to understand whether, and how, it can be appealed; for someone whose appeal has already been decided and who wants to understand whether a further cassation review is realistically available; and for anyone trying to understand, at a general level, how the appellate structure in Bulgarian criminal procedure actually works before deciding on next steps. It assumes a first-instance judgment already exists or is expected shortly; for the stages that come before that point, see the criminal defence lawyer hub, and, for the very earliest stage after an arrest or detention, the arrested in Bulgaria page.

It is not written for a civil appeal arising from a civil claim with no criminal element, which follows a different procedure under the Civil Procedure Code and is covered on the litigation lawyer page, nor for an appeal against a purely administrative sanction, covered on the administrative appeals page.

The two-stage structure: appeal, then cassation

Bulgarian criminal procedure generally provides for two distinct levels of challenge to a first-instance judgment, though how they apply can vary depending on the level of court that issued the first-instance decision and the nature of the case:

• Appeal (въззираждане). A challenge to the first-instance judgment, brought before the competent appellate court, which reviews the case on both the facts and the law. The appellate court can re-examine the evidence, hear the case afresh to the extent needed, and can uphold the first-instance judgment, amend it, overturn it, or, in some circumstances, send the case back to the first-instance court for the proceedings to be repeated in whole or in part because of a defect serious enough to require that.
• Cassation (касационно обжалване). A further, more limited review, available in cases that meet the applicable criteria, before the Supreme Court of Cassation of the Republic of Bulgaria — the final instance in the ordinary criminal court system. Cassation review is confined to points of law, not a fresh look at the facts: it examines whether the law was correctly applied and whether the proceedings below were properly conducted, not whether the appellate court's assessment of the evidence was the one a different court might have reached.

This structure means an appeal is a genuine second look at the whole case, while cassation is a narrower, more technical review confined to legal error. Treating the two as interchangeable, or assuming cassation offers the same kind of fresh hearing an appeal does, is one of the more common misunderstandings clients bring to this stage of a matter, and correcting that expectation early is part of giving an honest assessment of the realistic options.

Grounds for a criminal appeal

An appeal against a first-instance criminal judgment can generally be based on a combination of the following, depending on what actually happened in the specific case:

• Incorrect or incomplete factual findings. The first-instance court's assessment of the evidence was wrong, incomplete, or failed to properly account for evidence that was actually before it.
• Misapplication of the substantive criminal law. The conduct found proven does not actually amount to the offence the court convicted for, the wrong article of the Penal Code was applied, or the sentence imposed does not correctly reflect the applicable legal framework.
• A material breach of procedural rules. A defect in how the trial itself, or an earlier stage of the proceedings, was conducted — for example, a serious failure to respect a defendant's procedural rights — that was significant enough to have affected the outcome or the fairness of the process.
• An unjust or disproportionate sentence. Even where guilt is not seriously disputed, a sentence can be challenged as excessive, or as failing to properly account for a recognised mitigating factor, in light of the actual facts of the case and the applicable sentencing framework.

A well-prepared appeal identifies which of these grounds genuinely applies to the specific judgment, supported by the actual trial record, rather than asserting all of them generically in the hope that something sticks. An appellate court, like any court, engages far more seriously with a specific, evidenced argument than with a broad complaint that the outcome feels unfair.

Grounds for cassation

Because cassation review is confined to points of law, the grounds available at this stage are narrower than at the appeal stage. In general terms, cassation is directed at defects such as: a misapplication of the substantive law by the appellate court, a material breach of the procedural rules that affected the proceedings before the appellate court, and a sentence that is manifestly unjust in a legal sense — imposed outside the legal framework that should have applied, rather than simply a sentence the defendant considers too severe. Cassation is not a further opportunity to re-argue whether the appellate court weighed the evidence correctly; that assessment, once made properly and lawfully by the appellate court, is generally final. Whether a specific case genuinely raises a point of law capable of supporting a cassation challenge, rather than simply a renewed disagreement with the facts as found, is one of the first things to establish honestly before committing to this stage.

Deadlines: short, and specific to the judgment

As with administrative appeal deadlines elsewhere on this site, this page deliberately does not state a specific number of days for filing a criminal appeal or a cassation challenge, because doing so risks being wrong for a specific case and creates a false sense of certainty. What can be said honestly: deadlines in Bulgarian criminal procedure for both an appeal and a cassation challenge are counted from a defined event — typically the announcement of the judgment or the date it is properly served, depending on how the proceedings were conducted — and they are considerably shorter than many clients expect coming from a different legal system. Missing a deadline is one of the most common and most avoidable ways a genuinely arguable case is lost, not on the merits but on a technicality that a timely filing would have avoided entirely. Establishing the exact deadline that applies to a specific judgment, from the judgment itself and the current text of the Criminal Procedure Code, should be one of the very first steps taken once an unfavourable judgment is received — not something left until a case is reviewed in general terms weeks later.

What actually happens at the appeal stage

Where an appeal is filed, the appellate court reviews the case file, including the trial record and the evidence considered by the first-instance court, and can hear further evidence itself where that is appropriate to the grounds raised. Both the defence and the prosecution can appeal, and can each respond to an appeal filed by the other side, meaning a defendant's appeal does not automatically insulate them from a prosecution appeal seeking a harsher outcome on the same judgment. The appellate court then issues its own reasoned decision, which itself becomes subject to a further, more limited review by way of cassation in cases that qualify.

What actually happens at the cassation stage

A cassation challenge is filed with the Supreme Court of Cassation of the Republic of Bulgaria, setting out the specific points of law relied on. Because this stage does not re-examine the facts, the written submission carries particular weight: it needs to identify precisely which legal error is alleged, and why it matters to the outcome, rather than restating a general disagreement with how the case was decided. The Supreme Court of Cassation can uphold the appellate court's decision, overturn it, or, in some circumstances, return the case for further proceedings consistent with its own findings on the legal question raised.

Documents that matter at the assessment stage

• The first-instance judgment, in full, including its stated reasoning, and, once it exists, the appellate court's decision.
• Proof of the date the judgment was announced or served, since this fixes the deadline and is often the single most important document in the file at this stage.
• The trial record and the evidence considered, to the extent already available, so that the actual basis for the first-instance decision can be reviewed rather than assumed from the judgment's summary alone.
• Any procedural objections already raised during the trial itself, since these can matter to whether a specific ground is available on appeal.
• Correspondence with any lawyer already involved in the first-instance proceedings, where representation is changing at this stage.

Sending what already exists, even where the full file is not yet assembled, is normally the fastest way to get a useful initial view on whether an appeal or a cassation challenge is realistically worth pursuing, and by when it needs to be filed.

How a criminal appeal matter is assessed

An appeal or cassation enquiry is assessed in the same sequence as any other matter this practice takes on. First, a written description of the case and the judgment, including the date it was announced or served. Second, a check for conflicts of interest and for whether the matter genuinely falls within the current practice scope, including confirming realistically whether the deadline that applies to the specific judgment can still be met. Third, where the matter can be taken forward, a written scope covering exactly what work will be done — a deadline and merits review, a full appeal, or a cassation challenge — and the applicable fee. Fourth, once that scope and fee are agreed, the substantive work follows. This is the same process described on the criminal defence lawyer hub, with no separate or accelerated route for an appeal matter specifically.

Realistic framing: no outcome is guaranteed

It would be improper to promise that any particular appeal or cassation challenge will succeed. What can be said honestly is this: a judgment correctly identified as flawed on one of the recognised grounds, challenged within the correct deadline and supported by a properly prepared submission, has a materially better realistic prospect than a late filing or one that does not actually engage with the reasoning the court gave. Some first-instance judgments are, on a genuine review, correctly decided on the facts and the law, in which case the honest advice is to say so plainly rather than pursue an appeal with little realistic prospect simply because the outcome was unwelcome. Part of the value of an early, honest review at this stage is being told clearly where a specific matter actually stands before committing further time and cost to it.

What this practice does not do

To be direct about the limits of this service: this practice does not promise or predict the outcome of any appeal or cassation challenge, does not treat cassation as a second appeal on the facts when it is not, does not invent a deadline where the correct one has not yet been confirmed against the actual judgment, and does not offer an emergency or same-day filing service — a properly prepared appeal takes the time it genuinely needs, within whatever deadline actually applies, and that deadline is established as a first step rather than assumed.

Fees

Criminal appeal and cassation matters are not fixed by a public price list, because a deadline and merits review on a single judgment is a different piece of work from a full appellate hearing or a cassation submission. The professional fee is set out in writing as part of the proposed scope, before any work begins — see how fees are set. There is no default consultation fee published on this page, and no promise of a free initial call.
