Mechanism
Decreto-Lei n.º 138/2014 was issued by the Portuguese Government under the legislative authorisation granted by the Assembleia da República through Lei n.º 9/2014. It creates Portugal's initial horizontal investment-screening mechanism — the Regime de Salvaguarda de Ativos Estratégicos Essenciais — and operates as the foundational PT parent statute for FDI oversight in sensitive-sector infrastructure.
Key structural features:
1. Ex-officio trigger (no mandatory pre-notification). Unlike the Denmark ISA (2021), Netherlands Wet Vifo (2022), or Sweden Lag 2023:560, the Portuguese regime does not impose a mandatory pre-closing notification obligation on investors. The Council of Ministers can open a review ex officio — i.e., on the initiative of the competent sectoral minister or the government upon becoming aware of a transaction — but investors are not required to notify the government ahead of closing. This is a materially weaker procedural posture than the newer EU member-state mandatory-suspensory regimes and reflects the 2014 vintage of the statute, pre-dating EU Regulation 2019/452.
2. Scope: strategic essential assets in three infrastructure domains + national security. - Energy, transport, and communications: main infrastructure assets and assets providing essential services in these sectors. - National defence and security: assets linked to defence/security interests. - Acquirer nationality threshold: regime applies to non-EU/non-EEA investors acquiring control. EU and EEA acquirers are outside its scope (consistent with EU Treaty freedoms of establishment and capital).
3. Control concept. The Decree-Law adopts the de facto or de jure control standard as defined in national law and EU competition law (EU Merger Regulation / Commission Guidelines), incorporating the developed body of national-authority practice and ECJ case law. This means minority positions conferring negative control or material influence may in principle be reviewable.
4. Opposition procedure. Upon identification of a qualifying transaction: - The competent sectoral minister or the Council of Ministers can initiate review ex officio. - Review opens within a defined window of the government becoming aware of the transaction. - Investigation window: 60 working days from opening (extendable in complex cases). - A prohibition (opposition) decision requires a reasoned Council of Ministers resolution, proposed by the sectoral minister. - Prohibited transactions are declared null and void; the nullification is described as an "inherent risk of the transaction" that the investor assumes from the date of government awareness.
5. Authorising legislative base — Lei n.º 9/2014. The Assembleia da República delegated rulemaking authority to the Government to establish this regime via Lei n.º 9/2014. The Decreto-Lei is therefore subordinate legislation under the statutory authorisation; any future supersession by a new primary statute (e.g., transposing the proposed EU FDI Regulation update) would abrogate it.
Why severity 3
- Foundational but procedurally weak. The absence of a mandatory pre-closing notification obligation is the central limitation: unlike the modern suspensory-mandatory regimes (DK/NL/SE/AT/CZ/SK), Portugal cannot automatically freeze a transaction pending review unless the investor voluntarily suspends closing. Ex-officio review after closing creates enforcement complexity (post-closing unwind risk).
- Horizontal parent status. As the first and (as of this filing) only horizontal investment-screening statute in Portugal, DL 138/2014 covers the full breadth of strategic-infrastructure FDI — Sines LNG terminal, REN (electricity transmission + gas), EDP (generation and distribution), Galp (fuel/energy infrastructure), the Lisbon/Oporto port systems, and the NOS/Altice telecoms backbone. This breadth warrants 3 rather than 2.
- Pre-EU 2019/452 era regime. The EU Screening Regulation 2019/452 (applicable from October 2020) mandated EU-wide cooperation but did not require member states to create national screening regimes. Portugal's DL 138/2014 predates that framework and has not been replaced by a newer statute aligning with it. A future amendment or replacement to introduce mandatory pre-notification and mandatory-suspensory effect would warrant re-rating to 4.
- Atlantic/Iberian infrastructure centrality. Portugal hosts the Sines deepwater container terminal (one of Europe's largest, on the Atlantic trade lane), AICEP Portugal Global strategic assets, the Porto de Lisboa, REN's cross-Iberian electricity interconnections, sub-sea cable landing stations, and Galp's Atlantic-facing LNG infrastructure. Non-EU strategic acquirers in any of these assets fall within the regime's scope.
Downstream implications
- Sines LNG + Atlantic connectivity layer. Any non-EU/non-EEA investor acquiring control in Portuguese energy or port infrastructure — including PRC state-linked entities, Gulf SWFs, or US-sanctioned-country-linked capital — faces ex-officio opposition risk under DL 138/2014. Material to the Sines-Terminal-XXI (COSCO affiliate previously held a stake) and to any future Chinese port/energy exposure.
- EU FDI Regulation update (2025). The European Commission's proposed revised EU FDI Screening Regulation (2024 Commission proposal, political agreement 2025-12-11 per already-filed action if applicable) will impose minimum standards — including mandatory pre-notification in sensitive sectors — on all EU member states. When adopted, DL 138/2014 will require supersession or amendment to align Portugal with the mandatory-suspensory standard. File the amending Decreto-Lei as an

- PT peers in the EU FDI screening map. DL 138/2014 completes the Iberian Peninsula FDI-screening pair alongside the filed Spain Ley 19/2003 art 7bis + RD 664/1999 framework. Together, DM (AT, BE, CZ, DK, FI, FR, DE, IE, IT, NL, PL, RO, SK, SE, PT, ES) national FDI-screening regimes now have foundational-parent coverage in the register.
- REN (Redes Energéticas Nacionais). Portuguese electricity transmission + national gas transmission operator; Chinese State Grid Corporation acquired ~25% in 2012 — before DL 138/2014 — but any further acquisition or new non-EU strategic-infrastructure acquirer in Portugal's energy grid would trigger the regime. Track alongside the EU-level energy-security and critical-infrastructure themes.
Open questions
- 2025-26 update to align with EU FDI Regulation. If Portugal enacts a new investment-screening statute superseding DL 138/2014 to transpose the forthcoming revised EU FDI Regulation, file as a new action and mark this filing as
responds_to parent context.
- Enforcement record. No high-profile opposition decisions under DL 138/2014 have been identified in public sources. Verify with AICEP Portugal Global or the Ministério da Economia whether any ex-officio reviews have been initiated under the Decree-Law since 2014.
- REN / COSCO / CMHI exposure. Verify current ownership of strategic Portuguese infrastructure assets by non-EU/non-EEA state-linked entities and map against the DL 138/2014 threshold.
