Non-Discrimination Principle (GPA)

The Non-Discrimination Principle is the second pillar of the WTO Government Procurement Agreement's equality obligations, sitting alongside the national treatment principle. Where national treatment governs the relationship between foreign and domestic suppliers, non-discrimination governs the relationship between suppliers from different GPA parties: each must be treated as well as the best-treated group.

What is the Non-Discrimination Principle (GPA)?

Article IV of the revised GPA establishes two distinct non-discrimination obligations:

Most-favoured-nation (MFN) treatment. A GPA party must extend to all other GPA parties treatment no less favourable than it accords to any other GPA party. If a contracting authority in the EU grants preferential access to suppliers from one GPA party (for example, through a bilateral procurement agreement that gives better terms to US suppliers), it must extend the same treatment to suppliers from all other GPA parties. GPA MFN prevents a web of bilateral preferences that would fragment the multilateral procurement market.

No local preference. In covered procurement, a contracting authority may not treat one supplier less favourably than another on the basis of the degree of foreign affiliation or ownership. A company incorporated locally but majority-owned by foreign shareholders must not be disadvantaged relative to a fully domestic firm on that basis alone, provided the contract is otherwise covered by the GPA.

The non-discrimination obligation applies throughout the procurement process: in the drafting of technical specifications, in the design of qualification criteria, in the evaluation of tenders, and in the award decision. A contracting authority that applies evaluation criteria differentially depending on the nationality of the bidder violates this principle even if each individual criterion appears neutral on its face.

Why it matters for bidders

For a European supplier competing in a GPA-covered foreign market, the MFN obligation provides an important tool: if a competitor from another GPA party appears to have received preferential treatment in a procurement (for example, through prior access to technical briefings, pre-qualification waivers, or evaluation adjustments), the principle of non-discrimination provides grounds to challenge that treatment through the jurisdiction's challenge procedures.

The principle also matters in a defensive context. When an EU contracting authority enters into or applies terms from a bilateral procurement agreement with a non-GPA partner, it must be careful not to create preferences that would effectively discriminate against suppliers from GPA parties. The relationship between bilateral agreements and GPA MFN obligations requires careful legal management.

Example

The procurement authority of a GPA-party government has recently signed a bilateral trade agreement that gives preferential scoring bonuses to suppliers from one specific trading partner. A Dutch supplier bidding on the same contract notices that the evaluation matrix awards 5 bonus points to suppliers from the preferred partner country. This differential scoring may breach the GPA's non-discrimination principle, since the Dutch supplier (from an EU GPA party) is being treated less favourably than a supplier from the preferred partner. The Dutch firm can raise this through the applicable challenge procedure.

Frequently Asked Questions

Is the non-discrimination principle the same as the most-favoured-nation principle in goods trade?

The underlying concept is the same: extend to all parties the best treatment offered to any party. In the GPA context, MFN applies across GPA parties. It does not extend to non-GPA countries, so a contracting authority can legitimately treat suppliers from a non-GPA country less favourably than those from GPA parties. The GPA MFN obligation is narrower in scope than the general WTO MFN rule because only GPA parties are bound.

Can joint ventures or consortia face discrimination under this principle?

If a joint venture includes a GPA-party supplier and a non-GPA-party supplier, the treatment of the joint venture as a whole may be affected. GPA parties may legitimately limit access to suppliers from GPA parties and may therefore decline to extend GPA treatment to a bid where the non-GPA partner is the lead entity or holds a controlling interest. The precise rules depend on the buying country's coverage schedule and domestic procurement law.

Does the principle cover sub-contracting?

The GPA's non-discrimination obligations apply to the contracting authority's treatment of the prime supplier. Contracting authorities may not require prime suppliers to sub-contract to domestic firms as a condition of award, as this would indirectly discriminate against foreign prime suppliers whose supply chains are organised differently. However, the GPA does not directly regulate a prime supplier's own sub-contracting decisions.
