The Bavarian Supreme Court (BayObLG) issued a textbook decision on September 10, 2025 (case reference: Verg 6/25) on fundamental questions of public procurement law: How is the main object of a mixed contract determined and when may the award of specialist lots be dispensed with? The decision shows that the value share of the construction services only has an orientation function and does not solely determine the type of procedure.

Facts: The classification of a parking guidance system
The subject of the tender was the procurement and installation of a parking guidance system for nine parking spaces and two parking garages. The system was intended to reduce parking search traffic by displaying free capacities, in particular for specific vehicle types (e.g. motorhomes).
The contract was initially awarded nationally in accordance with VOB/A and was described as a “construction measure” with an estimated contract value of 1.39 million euros. The specifications contained the titles “Civil engineering” and “Display elements and control”. In addition to the price (70%), the concept (20%) and energy consumption (10%) were defined as award criteria. The concept for detection accuracy had to achieve a minimum score in order not to be excluded.
One bidder, specializing in electrical installation systems, objected to the tender. He was of the opinion that it was a supply and service contract and should have been put out to tender throughout Europe because the relevant EU threshold had been exceeded. Furthermore, he criticized the failure to divide the civil engineering services into lots. The North Bavarian Public Procurement Chamber rejected the application, as the value share of the construction services (approx. 40–49% of the total value) was the main focus.
Key point of the decision: The true main object lies in the function
The BayObLG overturned the decision of the procurement chamber and ruled in favor of the applicant. It found that the contracting authority must put the contract out to tender throughout Europe and divide it into lots.
1. qualification of the order: function takes precedence over value
In the case of a mixed contract (construction and supply and services), the main subject matter must be determined on the basis of the overall legal and economic circumstances.
- Role of the value shares: The value of the construction services (here approx. 40–49%) only has an orientation and control function. There are no fixed value limits.
- Focus on services: The court saw the focus on the supply and services. The contract was characterized by the design and construction of the parking guidance system, not by the required construction services.
- The decisive factor is the purpose: the purpose of the contract was to optimize the use of the existing parking spaces and to regulate traffic, not to intervene in the construction.
- Indicator award criterion: The outstanding importance of the criterion “concept” (detection accuracy and effort for recalibration) showed that the technical solutions for data acquisition and not the civil engineering work were the formative part of the contract.
2. violation of the requirement to award lots
The contracting authority violated Section 97 (4) sentences 2 and 3 GWB.
- Lot awarding as a rule: As there is a separate market for civil engineering and parking guidance system services, the creation of specialist lots was generally required.
- No sufficient documentation: The exception to the principle of awarding lots (overall award) must be justified by a comprehensive consideration of the conflicting interests, whereby the reasons for the overall award must prevail. The client had not documented its considerations prior to the announcement, which already constitutes an error.
- Insufficient justification: The generally associated coordination effort, a potential cost risk or the risk of a time delay cannot justify an overall award on their own.
Tips for public clients: focus and consideration
The decision is a strong signal that the formal designation of a contract or the pure value share of a service does not determine the applicable procurement regulations.
- Qualitative overall assessment: In the case of mixed contracts, the functional purpose of the project is decisive. Ask yourself: What is the contractual obligation? Is it the construction of a building (construction contract) or the integration of a complex technical solution for optimization (supply/service contract)?
- Lot awarding as a principle: Lot awarding is the rule. An overall award is only permitted in the case of compelling economic or technical reasons that require a comprehensive assessment and clearly outweigh the reasons.
- Exclusion of standard reasons: Typical risks such as an increased coordination effort, warranty issues, general cost risk or slight time delays do not justify an overall award.
- Documentation obligation: The decision not to award the lot must be comprehensively documented before the announcement. Postponing reasons is highly risky and insufficient in the event of a dispute.
Tips for bidders and applicants: Check lot formation and legal process
The ruling shows that bidders can successfully take legal action even in the case of supposedly clear-cut national construction tenders.
- Checking the main subject matter: If you feel excluded from participation due to the mixed nature (construction and technology/IT), check whether the actual focus of the service is on the supply of goods and services. The lower threshold value for supplies and services opens up the upper threshold legal protection.
- Objection to the overall award: Check whether a specialized lot formation would be possible. The client must provide detailed reasons for an overall award. Raise a complaint if the client’s justification is based solely on typical, inherent disadvantages of the lot award.
- Entitlement to submit an application without a tender: You may also be entitled to submit an application without submitting a tender if the alleged breach of public procurement law (e.g. failure to split lots) has conclusively prevented you from submitting a tender with a good chance of being successful.
