Integration between Fair Compensation and the Public Procurement Code

The dispute arose from a challenge to a tender for engineering services issued by a local administration, the Province of Viterbo, which allowed discounts on the entire base price, including the portion allocated to professional fees. As reported by specialized publications such as Il Sole 24 Ore and Il Quotidiano Giuridico, the legal challenge was brought by trade associations including OICE and CNI to protest the breach of non-derogable minimum parameters. The case was heard across both instances of administrative justice: following a ruling by the Lazio Regional Administrative Court (TAR Lazio) upholding the professionals' arguments, the Council of State confirmed the decision on appeal. The core of the ruling lies in the protection of fees, aimed at preventing competition among professionals from turning into a race to the bottom that devalues technical services.

The primary legal sources in this case are Law No. 49 of April 21, 2023, and Legislative Decree No. 36 of March 31, 2023.

1. Law No. 49/2023, Article 3, introduces so-called protective nullity for clauses setting compensation below ministerial parameters, establishing a principle of economic public policy.
2. The Public Procurement Code (Legislative Decree No. 36/2023), Articles 1 and 8, sets out the principles of result and contractual autonomy, aiming for maximum efficiency and open competition in tenders.
3. Annex I.13 to the same Code establishes the methods for calculating fees for technical services, incorporating the provisions of the so-called Parameters Decree. The legal question is whether the special nature of the Procurement Code can derogate from the minimum fee protection established by the general law on fair compensation.

Initially, administrative case law was divided between a restrictive approach, which considered discount bidding the core of public tendering and thus prevalent over minimum tariffs, and a broader interpretation. The latter, now consolidated by the Council of State, affirms the principle of necessary integration. The courts clarified that the two regulatory frameworks are not incompatible but must be interpreted systematically: the contracting authority must ensure compliance with fair compensation, as it is a mandatory rule protecting the dignity of professional work. Consequently, the minimum fee is fixed and non-discountable, while competition among bidders remains limited to ancillary cost components, such as general overheads and administrative expenses.

1. Analytically examine tender documents: always verify that the contracting authority has separated the professional fee from ancillary expenses and overheads.
2. Assess the risks of fee discounts: a reduction that infringes upon minimum fee parameters is not a competitive advantage, but a legal defect capable of invalidating the clause.
3. Engage professional associations: promptly notify professional bodies of tender documents failing to comply with Law No. 49/2023, enabling collective legal action or institutional interventions.
4. Distinguish fees from expenses: remember that only general expenses and ancillary charges may be subject to discounting in economic bids.
