digital trade frameworks, especially those emerging from OECD and United Nations initiatives. 2.2 Model Bilateral Investment Treaty Spain’s BITs and its approach to multilateral invest- ment treaties are broadly based on a model treaty framework, which has evolved over time. The most influential version was released in 2005, drawing from earlier OECD models and Spain’s own treaty practice. The key and distinctive provisions typically found in Spain’s model BIT framework are as follows. • FET standard: (a) It guarantees investors protection against arbitrary, discriminatory, or unreasonable state conduct. (b) It is often interpreted to include protection of legitimate expectations, especially regarding regulatory stability. • National and most-favoured nation treatment (MFN): (a) This principle ensures foreign investors receive treatment no less favourable than domestic investors or those from third countries. (b) MFN clauses may extend procedural rights (eg, access to arbitration) from other treaties. • Protection against expropriation – direct and indi- rect expropriation must be for a public purpose, non-discriminatory and accompanied by prompt, adequate, and effective compensation. • Free transfer of funds – investors can freely trans- fer capital, profits, dividends, and other payments related to their investment, subject to limited exceptions (eg, bankruptcy or criminal enforce- ment). • Full protection and security – it requires host states to provide physical and legal security to invest- ments. • Umbrella clause – it elevates contractual obliga- tions between the state and the investor to treaty level, allowing breach of contract claims under the BIT. • Investor–state dispute settlement (ISDS) – it offers access to international arbitration, typically ICSID or UNCITRAL, and often allows investors to choose between domestic courts and international arbitration.

Spain’s newer treaties and EU-led agreements include the following. • Provisions on corporate social responsibility (CSR), labour rights, and environmental protection. • Provisions on sustainable development (language promoting responsible investment aligned with climate and social goals). • In EU treaties, traditional ISDS is being replaced by a standing tribunal and an appellate mechanism. 2.3 Free Trade Agreements Spain is embedded in a broader free trade struc- ture through its membership in the EU. This grants Spain access to a vast network of EU-negotiated free trade agreements (FTAs) and investment protection frameworks. As an EU member since 1986, Spain participates in all trade and investment agreements negotiated by the EU (as 2.1 Bilateral and Multilateral Investment Treaties shows). These agreements offer market access, investment protection, and dispute resolution mechanisms for Spanish investors abroad and foreign investors in Spain. EU FTAs and investment treaties typically include the following. • FET standard – it protects investors from arbitrary or discriminatory treatment. • Protection against expropriation – it requires com- pensation if assets are seized. • Free transfer of capital – it ensures investors can repatriate profits and funds. • Transparency and CSR – newer treaties include provisions on labour rights, environmental stand- ards, and corporate responsibility. Spain’s treaties – especially those under the EU – are shifting toward modernised dispute resolution mecha- nisms. • ISDS – still present in older BITs and some EU agreements, allowing investors to sue states directly. • Investment court system (ICS) – a newer EU model replacing ISDS with a standing tribunal and an appellate body, aimed at increasing transparency and legitimacy.
