🔹 1. Definition of Public Interest Merger Test

A Public Interest Merger Test is a regulatory assessment applied by governments or competition authorities to evaluate whether a proposed merger or acquisition aligns with national or societal interests beyond pure commercial or competition considerations.

It usually examines:

Competition Impact – Will the merger reduce competition?
Economic Efficiency – Will it enhance productivity, innovation, or investment?
Employment – Will jobs be created or lost?
National Security – Does the merger involve sensitive sectors like defense, energy, or telecom?
Financial Stability – Especially in banking or strategic industries.
Consumer Welfare & Access – Impact on pricing, quality, or availability of goods/services.

🔹 2. Legal Framework

International/Regional Examples:

European Union
- Merger Regulation 139/2004 governs EU merger control.
- Article 21 allows intervention on public interest grounds:
  - Security of supply
  - Media plurality
  - Employment
United States
- Federal Trade Commission (FTC) and Department of Justice (DOJ) consider public interest indirectly via antitrust laws.
India
- Competition Act 2002 Section 31 considers public interest alongside competition.
South Africa & Canada
- Both allow “public interest” to include employment, small business impact, and ownership considerations.
