Swedish courts assemble the evidence puzzle, but do the pieces hold?

The consent law and the evidence gap

Since 2018, Swedish law defines rape and sexual assault by consent rather than force or threat ^[2]. Reports to police have increased, but the share of cases reaching conviction has not kept pace. The challenge, according to legal professionals interviewed by Tidningen Advokaten, lies in demonstrating what occurred when two accounts conflict and physical evidence is limited or absent ^[2].

Swedish courts apply the principle of free evaluation of proof, set out in Rättegångsbalken 35 kap. 1 § ^[1]. Any evidence can be presented, and its weight is judged by the court based on how trustworthy it appears. There is no hierarchy. A text message can matter as much as forensic findings, or more, depending on the circumstances.

What courts look for

Judges and prosecutors describe the process as assembling a puzzle ^[2]. Witness statements form the foundation, but they are assessed against forensic reports, digital traces such as messages or location data, and patterns of behaviour before and after the alleged event. A single piece rarely decides the outcome. Instead, the question is whether the pieces together support one account over another beyond reasonable doubt ^[2].

Digital records play a growing role. Messages exchanged before or after an encounter, timestamps from apps, and logs from devices can place people at a location or show what was said. Yet the reliability of these records depends on who kept them, how they were obtained, and whether they could have been altered. A screenshot presented by one party is evidence of what they claim was said, but without independent confirmation, the other party can dispute it.

The trust question

When evidence comes from a source controlled by one of the parties, the court must decide how much weight to give it. An unaltered record is more persuasive than one that could have been edited quietly. This is the evidence question in practice: not whether something exists, but whether it can be shown unchanged.

A sealed record, such as one created by a digital witness, does not prove the content is true. It shows that a particular record existed at a specific time and has not been altered since ^[3]. That distinction matters. In a case where one party claims a message was sent and the other denies it, a sealed copy can settle whether the message existed as claimed, but it does not determine whether the content is accurate or whether the sender's intent was as described.

eIDAS, the EU regulation on electronic identification and trust services, provides a framework for this. Article 41 states that an electronic timestamp cannot be denied legal effect simply because it is electronic ^[4]. A qualified timestamp carries a presumption that the date, time and integrity of the data are correct. WitniumChain does not currently hold qualified timestamp status under eIDAS, but the principle applies: a record that can be independently verified as unchanged has greater evidential weight than one that cannot.

Where records come from

The party presenting evidence typically controls it. A complainant may have kept messages, photos or voice recordings. The accused may have their own records. Each side presents what supports their account, and the court evaluates how reliable those records are.

When records are kept by a third party, such as a messaging platform or a location service, they can be obtained through legal process, but the platform's logs are only as trustworthy as the platform's systems. If the platform cannot show that its records are protected from tampering, their weight as evidence may be questioned.

A digital witness shifts the responsibility for proof. By sealing a record at the moment it is created, the person creating it no longer has to ask the court to trust that they kept it safe. The seal allows anyone to check whether the record has changed, without relying on the party who kept it.

What this means for you

If you are involved in any situation where a record might later be questioned, consider these questions:

• Who keeps the record, and could they alter it without detection?
• If you need to show later that a message, a photo or a document is unchanged, do you have a way to prove it?
• Would a sealed copy, created at the time, make your position clearer if someone challenges what you claim happened?

For legal professionals advising clients, the question is similar. When a client says they have evidence, ask whether they can show it is unchanged. A screenshot is a claim. A sealed record is a checkable fact.

For organisations handling sensitive records, such as healthcare providers, social services or insurers, the standard is higher. If a record could affect someone's rights or livelihood, the ability to show it has not been altered is not just helpful, it is often required. Under GDPR, data controllers must ensure integrity and confidentiality ^[5]. A seal makes that demonstrable.

What to watch

Sweden's courts will continue to apply free evaluation of proof. The legal framework is settled. What may change is the evidential standard expected of digital records, as courts become more familiar with the technology that can protect them. The question is not whether sealed records will be accepted, but whether records that could have been sealed, and were not, will be given less weight.

The AI Act does not directly apply to evidence in criminal proceedings, but it sets a precedent for how logs and records should be kept in high-risk systems. Article 12 of the AI Act requires certain AI systems to log events over their lifetime, and those logs must be complete and accurate ^[6]. The same principle applies to any record that might later be questioned: if it can be changed quietly, its value as evidence is lower.

For anyone who might one day need to prove what happened, the lesson is straightforward. Keep the record, seal it, and keep the seal where it can be checked. When the time comes to show what occurred, you will have more than a claim. You will have a fact that anyone can verify.
