Can You Appeal a Criminal Court Conviction to Supreme Court?

Appeals to the Supreme Court against judgments rendered on appeal by the Provincial Court that resolve Criminal Court sentences at first instance.

You have been convicted in a Criminal Court. The sentence does not exceed five years. And now everything is time-sensitive.
The question is logical: can I reach the Supreme Court or is everything decided in the Provincial Court?
The honest answer is this: the Supreme Court is not the natural next stop. First comes the appeal, always. And, after that, cassation exists, but only in very specific cases. Understanding which ones avoids wasting time, money and opportunities.

What a Criminal Court conviction means

The Criminal Court generally hears less serious crimes. In practice, this usually translates to moderate sentences, often equal to or less than five years imprisonment.

These judgments are not final immediately. The law provides for a mandatory second instance: the appeal before the Provincial Court.
This is important because it marks the path and limits of what comes after.

The Provincial Court does not repeat the trial, but it does review the judgment. It can confirm, modify or revoke the conviction.
Only after that appeal does the possibility of going to the Supreme Court arise, in certain cases.

When to appeal a Criminal Court judgment to the Supreme Court

Is cassation appeal available for sentences of five years or less?

Here is the core of the problem.

In this scenario, access to cassation moves within the framework of article 847.1 b) of the Criminal Procedure Act.

Stated clearly: it allows cassation appeals of certain judgments rendered on appeal by the Provincial Court, but with a very serious limitation.

Only appeals for violation of law are permitted.

What does cassation appeal for violation of law mean?

In Spanish criminal procedure, violation of law is regulated in article 849.1 of the Criminal Procedure Act.

Translated to plain language:

The Supreme Court reviews whether, accepting the proven facts as correct, the court correctly applied the crime, aggravating factors, mitigating factors or sentence.

What happened is not reviewed.
What is reviewed is how what happened was legally classified.

What the Supreme Court controls with this ground

When a cassation appeal for violation of law is filed, the Supreme Court always asks itself the same question:

«With these proven facts, does the conviction comply with criminal law or not?»

This implies

Why this ground is so important in Criminal Court convictions

When you come from a Criminal Court and the Provincial Court dismisses the appeal, in most cases this is the only possible ground for cassation.

This means that:

• either there is a clear legal error,
• or the appeal has no real prospects.

There is no middle ground.

A cassation appeal for violation of law is not won by arguing what happened, but by reading very carefully how the proven fact is written and asking:

«Does this really fit that crime and that sentence?»

That is where the technical work lies.
And that is where it is decided whether there is cassation… or inadmissibility.

The common mistake: wanting to use cassation for what it does not serve

In practice, many appeals fail due to a basic confusion.

A weak evidentiary evaluation is detected, a poorly reasoned judgment or an unconvincing conviction, and an attempt is made to force cassation to correct that. The approach is understandable. But it is legally erroneous.

In this procedural scenario, the Supreme Court cannot review the evidence. Not because it does not want to, but because the law does not permit it.

A very frequent case:

The proven facts could be disputed for lack of evidentiary rationality. The key testimony presents contradictions. The reasoning is sparse
