Dutch Public Procurement Act 2012: Complete Overview

Introduction

The Aanbestedingswet 2012 (Dutch Public Procurement Act 2012) is the primary legislation governing public procurement in the Netherlands. This law regulates how government bodies and public organizations must tender contracts for works, supplies, and services. The act came into force on April 1, 2013, replacing the earlier Decree on Public Procurement Rules (Bao) and the Decree on Procurement in Special Sectors (Bass).

Purpose of the act

The Procurement Act aims to ensure:

• Transparency: All potential tenderers receive equal access to information
• Non-discrimination: No unequal treatment based on nationality or place of establishment
• Proportionality: Requirements and criteria must be proportionate to the contract
• Competition: Safeguarding sufficient competition in public procurement

Scope

The act applies to:

1. Contracting authorities: Central government, provinces, municipalities, water boards, bodies governed by public law
2. Special sector entities: Organizations active in water, energy, transport, and postal services
3. Concession holders: Parties executing a concession agreement

Threshold amounts

The act distinguishes based on the estimated contract value:

Amounts apply for the 2024-2025 period and are revised biennially by the European Commission.

Above these thresholds, European procurement rules apply (Part 2 of the act). Below the thresholds, national rules apply (Part 1), which are less strict but still binding.

Structure of the act

Part 1: Contracts below the threshold

This part contains the basic rules for all public contracts, regardless of value:

• Chapter 1.1: Definitions
• Chapter 1.2: General provisions (procurement principles)
• Chapter 1.3: Publication and timeframes
• Chapter 1.4: Selection and award
• Chapter 1.5: Special provisions (reserved contracts, SME-friendliness)

Part 2: European procedures

For contracts above the thresholds, the act prescribes European procedures:

• Open procedure: Anyone may submit a tender
• Restricted procedure: Pre-selection, then invitation
• Competitive dialogue: For complex contracts
• Competitive procedure with negotiation: Negotiation after initial submission
• Innovation partnership: For innovative solutions
• Negotiated procedure without publication: Only in exceptional cases

Part 3: Special sectors

Specific rules for water, energy, transport, and postal services. These sectors have slightly more flexibility in their procurement procedures.

Part 4: Concessions

Rules for granting concession contracts for works and services.

Key principles

Proportionality

The Guide to Proportionality is a mandatory guideline in procurement. Requirements, conditions, and criteria must be reasonably proportionate to the subject of the contract.

Clustering and splitting

The act contains rules on combining (clustering) contracts:

• Clustering is only permitted when proportionate
• Contracting authorities must justify clustering
• Division into lots must be considered to promote SME access

Legal protection

The Procurement Act provides various legal remedies:

1. Complaint handling: Each contracting authority must have a complaints procedure
2. Committee of Procurement Experts: Independent advisory body for complaints
3. Summary proceedings: Injunctive relief before the civil court
4. Full proceedings: Damages after the fact

Standstill period (Alcatel period)

After the award decision, a waiting period of at least 20 calendar days applies before the contract may be concluded.

Conclusion

The Aanbestedingswet 2012 forms the foundation of Dutch procurement law. Knowledge of this act is essential for both contracting authorities and tenderers.
