Investment Arbitration and Investment-Related Disputes in Tunisia
Protect investments, anticipate disputes and defend the interests of international investors. A dispute with a public authority, a regulatory change affecting a project's profitability or a measure that may compromise an investor's rights can have major financial consequences. For foreign companies operating in Tunisia, these situations raise essential questions: which protection mechanisms apply, which forum can be seized, and under what conditions is an international arbitration proceeding available? Investment arbitration is, in certain circumstances, a means of settling disputes between foreign investors and States. Whether it is available depends notably on the applicable treaties, the nature of the investment, the investor's nationality and consent to arbitration.
Investment Arbitration and Investment-Related Disputes in TunisiaKey figures and 2026 developments

The legal framework for investment arbitration in Tunisia
Legal protection of an international investment may rest on several complementary instruments.
The legal framework for investment arbitration in Tunisia
Bilateral investment treaties
Bilateral investment treaties (BITs) may provide guarantees protecting investors of one contracting State when they invest in the other. Depending on the applicable text, these guarantees may cover treatment of the investment, transfers of funds, expropriation measures or dispute-settlement mechanisms.
Tunisia has concluded several such agreements. Their scope must nonetheless be assessed case by case: some are in force, while others are signed but not yet in force. The investor's nationality, the ownership structure and the conditions set out in the treaty are decisive.
The legal framework for investment arbitration in Tunisia
Tunisia is a member of the International Centre for Settlement of Investment Disputes (ICSID), a World Bank Group institution that administers investor–State dispute settlement proceedings.
Access to ICSID is not automatic. It requires that the jurisdictional conditions set out in the applicable instruments be met, including valid consent to arbitration.
Depending on the legal basis of the dispute, a proceeding may also fall under other international arbitration rules, notably those of UNCITRAL.

Tunisian law and investment contracts
Contracts with public entities, administrative authorisations, concessions and financing agreements can also play a central role.
Contract-based arbitration must be distinguished from treaty-based investment arbitration. The two mechanisms do not necessarily follow the same jurisdictional rules, guarantees or admissibility conditions.
Which disputes may give rise to investment arbitration?
An investor may consider an international claim when State measures or investment-related disputes are liable to impair rights protected by an applicable instrument.
These situations do not automatically amount to violations of international law. The analysis must establish the applicable obligations, the relevant facts and the link between the contested measures and the investor's rights.
- ✓Expropriation and dispossession: measures affecting control or ownership of assets, subject to the conditions of applicable law
- ✓Regulatory measures: administrative decisions or regulatory changes that may substantially affect an investment
- ✓Withdrawal or modification of authorisations: disputes over licences, concessions or permits required to operate a project
- ✓Contractual difficulties with public entities: non-performance, payment delays or termination of contractual relations, where the legal basis for the claim allows it
- ✓Treatment of the investor: measures that may raise issues of discrimination, unfair or inequitable treatment or breach of other treaty guarantees
A case involving Tunisia registered in 2026
On 7 April 2026 ICSID registered Shell Tunisia Upstream Limited and Shell Tunisia LPG S.A. v. Republic of Tunisia (ARB/26/14). The dispute concerns the hydrocarbons sector and relies on the United Kingdom–Tunisia bilateral investment treaty of 1989.
As of 6 August 2026 the proceeding was pending and arbitrator appointments were continuing. Registration of this case is a concrete example of investment litigation involving Tunisia; it does not prejudge the outcome or the merits of the parties' claims.
These figures relate to ICSID's worldwide activity and not exclusively to disputes involving Tunisia. They nonetheless underline the importance of checking, from the structuring of an investment, which instruments may protect the operation. UNCTAD's Investment Dispute Settlement Navigator lists public proceedings based on international investment agreements; its database is not necessarily exhaustive. A registered case does not mean that a breach has been established or that compensation will be awarded.
How to prepare an investment arbitration proceeding?
An effective strategy starts well before filing a request for arbitration. Early identification of the legal basis and preservation of evidence can be decisive.
- ✓Step 1 — Identify the applicable protection instruments: investment treaties, contracts, national laws and dispute-settlement clauses; verify investor nationality, the ownership chain, the investment date and access conditions to arbitration
- ✓Step 2 — Build the legal and financial file: contracts, authorisations, administrative correspondence, contested decisions, financial reports and economic valuations; a documented chronology supports analysis of alleged liability, time limits and loss
- ✓Step 3 — Assess available settlement routes: compare arbitration with negotiation, mediation, court proceedings or contractual procedures; check preconditions, limitation periods, forum clauses and notice obligations
- ✓Step 4 — Prepare the procedural strategy: tribunal jurisdiction, admissibility of claims, evidence, quantum, counsel selection and coordination with any parallel proceedings
Recognition and enforcement of arbitral awards
Obtaining a favourable award does not, on its own, guarantee recovery of the sums awarded.
Recognition and enforcement rules depend notably on the legal regime of the award, the institution concerned and the assets targeted. Awards rendered under the ICSID Convention follow a specific regime, distinct from that applicable to many international commercial awards.
It is therefore essential to anticipate asset location, any applicable immunity rules and the procedures that may be required to obtain effective enforcement.

Frequently asked questions on investment arbitration in Tunisia
Can a foreign investor sue the Tunisian State directly before an international arbitral tribunal?
It depends on the applicable legal basis and consent to arbitration. An investment treaty may, under certain conditions, give an investor a direct claim against a State. The investor's nationality, the definition of investment and the procedural conditions must be verified.
Frequently asked questions on investment arbitration in Tunisia
Does every dispute with a Tunisian administration fall under investment arbitration?
No. An administrative or contractual disagreement does not automatically amount to an investment arbitration dispute. It must be determined whether the matter arises under a treaty, a contract containing an arbitration clause or another legal mechanism.
Frequently asked questions on investment arbitration in Tunisia
What is the difference between commercial arbitration and investment arbitration?
Commercial arbitration generally concerns a dispute between parties to a commercial or contractual relationship. Investment arbitration primarily addresses disputes between an investor and a State based on an investment-protection instrument. The parties, legal bases and applicable rules may therefore differ.
Frequently asked questions on investment arbitration in Tunisia
Can an arbitral award be enforced in Tunisia?
