More Regional Antitrust: Competition law in West Africa at the hands of ECOWAS

After the successful launch (and by now, first decade) of its Eastern regional counterpart, the COMESA Competition Commission, as of today, West Africa’s ECOWAS body likewise boasts a supra-national antitrust enforcement regime. AAT will be following its path closely.

By Jannes van der Merwe

The Economic Community of West Africa States (“ECOWAS”) was established by fifteen West Africa countries (“member states”) in 1975 when the member states signed the ECOWAS Treaty, with the aim and objectives to maintain and enhance economic stability and development in Africa.[1] The member states signed the revised treaty in 1975, currently governing the member states.

The current member states are Benin, Burkhina Faso, Cabo Verde, Côte d’Ivoire, The Gambia, Ghana, Guinea, Guinea Bissau, Liberia, Mali, Niger, Nigeria, Senegal, Sieera Leone and Togo.

Authority Established in 2008

In 2008 ECOWAS implemented two pieces of legislation through the authority of the treaty to steer the competition framework within the member states. The first was the Supplementary Act A/SA.1/12/08, and the second Supplementary Act A/SA.2/12/ 08.

Supplementary Act A/SA.1/12/08:

The purpose of this piece of legislation (known as the Community Competition Rules) nutshell is to promote competition, enhance economic efficiency, prohibit anti-competitive conduct that restricts or distorts competition, ensure consumer welfare and to expand opportunities for domestic enterprises of the member states. [2]

Supplementary Act A/SA.2/12/ 08:

The purpose of this piece of legislation was to establish a regional body to be known as the ‘ECOWAS Regional Competition Authority’ (“the Commission”) to govern, oversee and implement the Community Competition Rules.

The Commission

The formal launching of the Commission took place in May 2019. In December 2021, together with further enactment of legislation, the Council of Ministers of ECOWAS amended Supplementary Act A/SA.2/12/ 08 to, inter alia, enhance article 2, governing the bodies of the ERCA[3].

The amendment established two formal bodies of the ERCA, being the Council and the Executive Board of the ERCA, together with the Executive Directorate who is the administrative, investigative and implementing body of the Council’s decisions[4].

On 2 October 2024 the newly elected Council of the Commission will be sworn in at Banjul, the capital of the Republic of Gambia. See photo below.

This event will mark the dawn of a new day for competition in West Africa, whereby the Commission, through the Council, will become fully functional in order to administrate and give effect to the Competition Rules to member states.

Legal Framework

The Commission, through the Council, will be able to give effect to the preamble of the Treaty and align a vitally important piece that was missing from the practical application of the treaty.

The Community Competition Rules will be the governing legislation providing the umbrella under which the Commission will operate.

During December 2021, the Council of Ministers for ECOWAS further enacted regulations to govern the rules and procedures to give effect to the articles of the Community Competition Rules established in 2008.

A brief description of all the relevant legal framework will be discussed below.

 The Competition Community Rules

The Competition Community Rules will regulate, inter alia, Agreements and Concerted Practices in Restraint of Trade; Abuse of Dominant Position; Mergers and Acquisitions; State Aid; Public Enterprises; Compensation for Victims of Anti-Competitive Practices; Authorisation and Exemptions; Agreements Concluded by Member States and the Application and Implementation of the Community Competition Rules[5].

ERCA’s Rules of Procedure in Competition Matters

Regulation C/REG.24/12/21[6] was established to set out the rules and procedures of the ECRA in competition matters and by doing so, harmonising competition laws, procedures, cooperations, investigations, exchange of information, decision making, enforcement, sanctions and compensation[7].

Supplementary Act A/SA.3/12/21

The amended act’s new article 3 provides a positive duty on the Commission to represent ECOWAS wherever necessary in matters of competition and consumer protection[8].

Mergers and Acquisitions in ECOWAS

Regulation C/Reg. 23/12/21[9] was established to set out the rules and procedures for mergers and acquisitions.

This regulation requires that merging parties of member states that meets the threshold will have to obtain prior approval before implementing. The merger threshold is governed by enabling Rule PC/REX.1/01/2024[10]

Leniency and Immunity Proceedings in Competition within ECOWAS

Regulation C/REG.22/12/21[11] was established to set out the rules, conditions and procedures of leniency and immunity applications to the Commission. Simultaneously, this regulation is a guide to the Commission in the exercise of its investigative and prosecutorial discretion in illegal cartels who, through their cooperation, help to reveal Cartel conduct[12].

Regulation C/REG.22/12/21 is accompanied with enabling Rule PC/REX.1/01/24[13] containing the manual for leniency and immunity applications and what leniency and immunity the Commission may grant for enterprises of member states which are engaged in anti-competitive behavior and who voluntarily disclose information to facilitate the Community Competition Rules.

Final Word

The operational ECOWAS Regional Competition Authority and the implementation of a functioning Council for the ECOWAS Regional Competition Authority is a leap forward in the West Africa competition sphere and will protect enterprises and enhance competition within the West Africa markets, providing benefits for entrepreneurs, enterprises and consumers.

Notifying African M&A – balancing burdens & costs

Merger filings in Africa remain costly and cumbersome

By AAT guest contributor Heather Irvine, Esq.

The Common Market for Eastern and Southern Africa Competition Commission (COMESA) recently announced that it has received over US$3 million in merger filing fees between December 2015 and October 2016.

heatherirvineAbout half of these fees (approximately $1.5 million) were allocated to the national competition authorities in various COMESA states. However, competition authorities in COMESA member states – including Kenya, Zambia and Zimbabwe – continue to insist that merging parties lodge separate merger filings in their jurisdiction. This can add significant transactional costs – the filing fee in Kenya alone for a merger in which the merging parties combined generate more than KES 50 billion (about US $ 493 million) in Kenya is KES 2 million (nearly US $ 20 000). Since Kenya is one of the Continent’s largest economies, significant numbers of global transactions as well as those involving South African firms investing in African businesses are caught in the net.

Merging parties are in effect paying African national competition authorities twice to review exactly the same proposed merger. And they are not receiving quicker approvals or an easier fling process in return. Low merger thresholds mean that even relatively small transactions, often with no impact on competition at all, may trigger multiple filings. There is no explanation for why COMESA member states have failed to amend their local competition laws despite signing the COMESA treaty over 2 years ago.

Filing fees are even higher if a proposed cross-border African merger transaction involves a business in Tanzania or Swaziland– the national authorities there have recently insisted that filing fees must be calculated based on the merging parties’ global turnover (even though the statutory basis for these demands are not clear).

The problem will be exacerbated even further if more regional African competition authorities, like the Economic Community of West African States (ECOWAS) and the proposed East African Competition authority, commence active merger regulation.

Although memoranda of understanding were recently signed between South Africa and some other relatively experienced competition regulators on the Continent, like Kenya and Namibia, there are generally few formal procedures in place to harmonise merger filing requirements, synchronise the timing of reviews or align the approach of the regulators to either competition law or public interest issues.

The result is high filing fees, lots of duplicated effort and documents on the part of merging parties and the regulators, and slow merger reviews.

If African governments are serious about attracting global investors, they should prioritise the harmonisation of national and regional competition law regimes.
