Legal Protection for Investors in Public-Private Partnership Agreements

Abstract

Public Private Partnership (PPP) agreements have become an important legal instrument for financing and delivering public infrastructure by combining public sector objectives with private sector investment and expertise. Despite their economic significance, PPP projects expose investors to various legal, political, financial, and regulatory risks that may undermine investment certainty and project sustainability. Effective legal protection is therefore essential to ensure investor confidence while preserving the government's authority to regulate in the public interest. This study examines the legal mechanisms that protect investors in Public Private Partnership agreements and evaluates their role in promoting legal certainty and balanced contractual relationships. Employing a normative legal research method through statutory, comparative, and conceptual approaches, the study analyzes legislation governing public-private partnerships, investment law, contract law, and relevant international legal principles concerning investor protection and dispute resolution. The findings demonstrate that investor protection extends beyond contractual guarantees and depends on transparent regulatory frameworks, equitable risk allocation, effective dispute resolution mechanisms, and consistent enforcement of contractual obligations. The study concludes that a balanced legal framework, integrating contractual autonomy with regulatory accountability and institutional certainty, is fundamental to strengthening investor confidence, encouraging sustainable infrastructure development, and ensuring the long-term success of Public Private Partnership projects.
