Da Costa case and legal certainty: how an acquittal verdict could ruin two lives

Catrine da Costa was murdered and dismembered in 1984. Two doctors were acquitted of murder charges in 1988 but were singled out in the reasons for the dismemberment. It was not possible to appeal. Almost 40 years later, the state gives them two million kronor each.

The

Da Costa case is not just the story of an unsolved death. It is the story of a judicial process in which an acquittal had the same social and professional effect as a conviction. It is also an examination of how sentencing reasons, media, administrative decisions and political inaction can together create

a legal impasse.

The first thing that has to be said is that Catrine da Costa is the original victim of the crime. She was found dismembered in 1984, the cause of death could not be determined and no one has been convicted of her murder. The case was later time-barred. Reviewing the legal abuse against the two designated doctors must not make her

death a footnote.

The second is that the rule of law problem in the case does not require knowing who killed her. Quite the opposite: the core issue is how the state treated two people when the evidence wasn't enough to

convict.

The central paradox: exonerated but singled out

In 1988 Thomas Allgén and Teet Härm were acquitted of the murder of Catrine da Costa. At the same time, the district court wrote in the reasons for the verdict that they had dismembered the body. As the conviction was exonerating, there was no conviction to appeal. Since the act on which the court ruled was time-barred and not part of the judgment, they could not have the question of guilt examined in a higher

instance in the usual way.

That is why the case has become a legal certainty symbol. A court shall convict or acquit in the act to which the indictment relates. If, instead, the court inserts a damaging statement of guilt into the grounds of judgment, without this being able to be attacked as a conviction, a judicial no-man's land arises. The person is cleared on the record but guilty in

community court.

SVT reported on 16 June 2026 that the government will award the two men two million kronor each in ex gratia compensation. According to SVT, Minister of Justice Gunnar Strömmer described the problem as follows: they were in practice convicted of a crime for which they had not been charged, which was time-barred and which could

not be appealed.

Timeline at a Glance

What went wrong?

1. The reasons for the conviction were a sentence without a verdict. The most serious lack of legal certainty is that the court effectively created a guilty mark without giving those singled out an appealable conviction. That is the crux of the government's later criticism.

2. Prescription was used as a legal valve. If a deed is time-barred, the state should not be able to use it as a side track to nevertheless pronounce guilt with devastating consequences. Limitation is not just a technicality. It indicates that the state is no longer allowed to prosecute the deed

.

3. The management track compounded the damage of the judgment grounds. The medical credentials were later withdrawn. Thus, the statement of guilt moved from the text of the court to a practical professional ban. The question no longer became just what the district court had written, but how other parts of the state built on

the writing.

4. The media acted as amplifiers. SVT's own programme description writes that the 2024 documentary series examines how the justice system came to the conclusion that the doctors were guilty and how the process became one of Sweden's most hotly debated. SVT's news article states that the documentary showed that the designation was made on very weak grounds. The role of the media was twofold: first they drove up the pressure, later, investigative journalism contributed to redress.

5. The chain of child witnesses and circumstantial evidence became too heavy for its carrying capacity. SVT Play describes how the investigation gained new momentum through information that a young child would have seen a dismemberment and how experts were called in to assess the child's story. In a legally secure process, such data must be handled with extreme caution, especially when adults' interpretations, memory, affect, and questioning techniques may become part of the evidence.

6. No learning mechanism closed the case. In the January 2025 parliamentary question, the case is described as a judicial scandal and compared to the Quick case. The question was whether the government should appoint an independent commission. The Attorney General replied at the time that he was following the matter but did not wish to speak out because those singled out

were considering legal avenues of action.

The judge and the adjudicators: what can be reviewed?

There are two different levels here. The first is the coated procedural level. A first main hearing had to be rescheduled after a committee member spoke to Aftonbladet about the court's reasoning. That in itself is serious. The deliberation of the court is closed, and the adjudicators are the judges of the case. If a judge speaks next to his mouth, confidence in the court hearing the case in the courtroom and not in the media logic is disturbed

.

The second level is personal connections, networks, and any ties of judges or adjudicators. This requires a review of documents and sources. In the open sources reviewed for this article, there is insufficient verified evidence to single out a particular judge or adjudicator with private connections who would have influenced the decision. It would not be legally safe to replace a criticized verdict with loose innuendo of your own

.

On the other hand, what should be examined in a serious commission is concrete: who sat in court at each hearing, what political committee mandates did they have, what was said in media contacts, how were questions handled, what contacts existed between police, prosecutors, experts and the media, and what documents formed the basis for the formulation of the reasons for judgment?

Why free and trap at the same time?

It is not possible to know for sure why the court chose the construction that came to characterize the men's lives. But it is possible to formulate cautious hypotheses, based on the mode of the process and the latter criticism

.

One possible explanation is compromise. The court may have perceived that the murder charge was not proven, but at the same time wanted to point out that it nevertheless believed that the men handled the body. In that case, there will be a compromise between the requirement of proof for murder and a moral conclusion about the course of events. The problem is that such a compromise does not belong in a criminal judgment if it lacks an appealable judgment.

Another possible explanation is pressure. The Da Costa case was medially charged, brutal and politically sensitive. When a community demands answers in a high-profile case, a court may be tempted to provide a narrative even when the evidence is insufficient for conviction. It may give the sense that the justice system has solved something anyway, but the price will be that the uncertainty is placed

on the defendant.

A third possible explanation is institutional self-protection. If police and prosecutors for a long time pursued a trail, a perfectly clean acquittal verdict could appear as a failure of the investigation. A statement of guilt in the grounds of judgment can then, consciously or unconsciously, soften the image of the failure of the system. This is precisely why courts must be particularly disciplined: the court's job is not to save

the reputation of investigations.

A fourth possible explanation is that the court underestimated the consequences. The court may have viewed the writing as a legal judgment without understanding that it would become the basis for the revocation of credentials, social stigma, and forty years of public debt. That explanation doesn't make the error any less. It just shows how dangerous sentencing reasons can be when they deal with guilt outside

of the judgment.

$2 million: where does the sum come from?

The open reporting shows that Allgén and Härm requested SEK 5 million each. The government granted two million each. Aftonbladet's Oisín Cantwell writes that five million was “haggled” to two million per person, stressing that this is not compensation or compensation for lost work income but a symbolic gesture

.

That is the important point: in the open sources reviewed, there is no transparent calculation model explaining why the sum was just two million. Sveriges Radio describes the compensation as ex gratia, i.e. compensation for people who have been mistreated by the state. SVT states that the motive was the extensive suffering the men had endured. But none of these sources presents a table of lost income, mental suffering, occupational prohibitions, social isolation, age, previous processes

or the state's debt share.

That makes the sum possible to question from two sides. It can be seen as high because the government pays without a court-determined liability for damages. At the same time, it can be seen as very low when compared with almost 40 years of professional loss, singling out, illness, isolation and the absence of the possibility of legal exoneration. The bottom line is that two million seems like a political and moral ex gratia level, not a full compensation for

actual harm.

Lessons of the rule of law

The

Da Costa case shows that legal certainty is not just about the final line in a judgment. It is about the whole chain: how the police lock down a hypothesis, how the prosecutor chooses the prosecution, how experts are used, how judges handle their role, how reasons for sentencing are formulated, how media reinforce guilt and how administrative authorities build on a court

text.

The most dangerous construct in the case was not only that two people were acquitted but singled out. It was that the designation was placed where the rule of law had the weakest remedy: on grounds of conviction that hurt as a conviction but could not be appealed as a conviction

.

Therefore, if an independent commission is ever appointed, it should not simply ask whether Allgén and Härm were mistreated. It should ask what procedural rules, court cultures, media logics and authority decisions allowed an acquittal to serve as a lifelong sentence
