Claims for Compensation Under and Outside Contracts Following the Rambøll Ruling

The Supreme Court recently handed down a ruling in HR-2025-1115-A (Rambøll), which provides further clarification on the conditions that must be met in order for so-called tort-based claims to be brought in contractual relationships, and how these claims relate to contractual liability. This article reviews case law and summarises the legal situation.

Contractual liability and tort liability

Contractual liability and tort liability constitute two main categories of liability under tort law. The distinction is particularly important in terms of the requirements for liability, the losses that can be claimed for compensation, and the rules that apply to limitation periods, limitation of liability and complaints.

Contractual liability is based on contract law, whereby the parties have agreed to certain obligations towards each other. Liability for damages in contracts generally requires that there has been a breach of contract, and liability is often regulated by the provisions of the contract and background law.

Tort liability (outside of contract), on the other hand, is based on breaches of general standards of conduct that apply regardless of contract. This typically applies to breaches of unwritten standards or statutory obligations that are not contractually agreed between the parties. Traditional and general damages are an example of this.

Tort liability may arise both within and outside contractual relationships. In contractual relationships, there is a fundamental question of whether and when tort liability can supplement or compete with contractual liability. Firstly, this may raise the question of whether claims that are not based on breach of contract can be brought in a contractual relationship. Questions may also arise as to whether, outside contractual relationships, claims based on breach of contract can be brought against third parties.

The Rambøll ruling

Over the past decade, the Supreme Court has heard several cases in which the relationship between contractual and non-contractual liability has been gradually clarified, mainly through what are often referred to as the “Bori rulings”, but also through last year’s “Bank Fraud” ruling.

The Rambøll ruling concerned the question of whether tort liability could be imposed for losses resulting from a failure to fulfil a duty of care in a contractual relationship, where the loss was purely financial. The ruling provides further clarification on the conditions that must be met in order for tort-based claims to be brought in contractual relationships.

The Supreme Court summarises and continues to apply the criteria previously developed in the Bori judgments, but clarifies that the distinction between contractual and tortious liability must be maintained in order to safeguard predictability and risk control in contractual relationships.

The Supreme Court clarifies that there must be a breach of an external, general standard of conduct outside the contractual relationship in order for tort-based claims to be brought in a contractual relationship. However, this standard of conduct does not need to be “established”.

The Supreme Court also emphasises that a standard of conduct stipulated in the contract cannot form the basis for tort liability, and that a breach of contract or a breach of contractual duties of loyalty or care is not sufficient. In addition, a broad assessment must be made of whether it is reasonable to impose liability.

What does this mean?

The development of the boundary between contract-based and tort-based claims can be summarised as follows:

Judgment Legal ruling(s)
Bori
(HR-2015-537-A)
Tort liability may be imposed for serious breaches of public law obligations, but a broad assessment must be made that takes into account the extent of the loss, the seriousness of the breach, the interests protected and enforcement considerations. A person who has several grounds for a claim may, in principle, choose which of these to assert, but the right of choice may be limited if there are clear indications in the sources of law.
Fire compartment
(HR-2017-1834-A)
It takes a lot for tort liability to arise in contractual relationships. A broad assessment must be made, and the existence of a contractual defect alone is not sufficient.
Solem
(HR-2020-312-A)
Tort liability may arise for breaches of public law obligations even if there is no breach of contract in the contractual chain. A broad assessment must be made according to the Bori I criteria, and such claims must not undermine the system and balance of contract law.
Kruse Smith
(HR-2021-2201-A)
It takes a lot for tort liability to arise in contractual relationships, and there must be a specific basis for deviating from the liability rules of contract law. A broad assessment must be made according to the Bori criteria.
Bank fraud
(HR-2024-990-A)
Non-contractual liability may also be invoked in contractual relationships, but this presupposes a breach of an (established) external standard of conduct.
Rambøll
(HR-2025-1115-A)
It is not sufficient that there has been a breach of contract. It must be demonstrated that there has been a breach of an external, general standard of conduct outside the contractual relationship, but this does not need to be “established”. A standard of conduct that follows from the contract cannot give rise to tort liability.

The following may then be a summary of the legal situation as of today:

  • Tort liability may supplement contractual liability, but only where there is no breach of contractual obligations and where there are specific reasons for imposing liability outside the contract.
  • It takes a lot for tort liability to arise in contractual relationships. Tort liability must not undermine the considerations of predictability and risk control in contractual relationships.
  • There must be a breach of a general trading standard that is not derived from the contract, but from external legal sources (such as laws, regulations, unwritten law). It is not sufficient that there is a breach of contract or a breach of contract-based loyalty or duty of care obligations.
  • The injured party must have suffered a financial loss, and there must be an adequate causal link. The loss must be protected by tort law, assessed according to criteria such as the size of the loss, the seriousness of the breach of duty, the interests protected and enforcement considerations. A broad assessment must be made of whether it is reasonable to impose liability.
  • It is permissible to regulate and limit tort liability in contracts, for example through limitations of liability or complaint deadlines, as long as this does not conflict with mandatory legislation or fundamental principles.

However, several questions remain that may be suitable for future elaboration and clarification, including:

  • It is unclear where the line between contractual obligations and general commercial standards lies, and which standards can be considered “external” in this context. This leaves room for interpretation in the grey area between contractual and tortious liability, particularly in more complex contractual relationships.
  • The assessments to be made appear to be discretionary, and limited guidance is provided on how this discretion should be exercised.
  • The rulings have mostly concerned breaches of public law obligations in construction contracts. It is questionable whether there may be grounds for other assessments in other contexts.
  • It is unclear how the broad assessment model used in the Bori judgments will be coordinated with the traditional conditions of adequacy and protection of interests.

The Supreme Court has also acknowledged that further rulings are needed to establish sufficiently precise standards in this area. The final word on this issue has therefore not yet been spoken, but the Rambøll ruling provides useful clarification.
