<![CDATA[This article addresses the urgent question of how the integration of Maqashid Shariah and the Green Constitution can serve as a normative-legal framework to respond to the escalating phenomenon of illegal investment in Indonesia. Against the backdrop of rampant technology-based fraudulent investments including robot trading, fake crypto assets, and pyramid schemes and their devastating socio-ecological impacts, this study employs a qualitative method of legal document analysis, examining cases of fraudulent investment alongside the Job Creation Law (UU Cipta Kerja) and its environmental implications. The study argues that illegal investment violates all five core objectives of Maqashid Shariah (al-kulliyat al-khamsah) protection of religion, life, intellect, lineage, and wealth while simultaneously undermining the constitutional guarantees of environmental protection embedded in Indonesia's Green Constitution. The findings demonstrate that reactive legal enforcement alone is insufficient to combat the complexity of investment-related fraud. The principle of ḥifẓ al-māl in Maqashid Shariah highlights the ethical imperative to protect wealth proactively, advocating for transparency, equity, and distributive justice in financial regulation. Simultaneously, the Green Constitution anchors environmental sustainability and social justice as constitutional obligations, emphasizing the role of law in safeguarding both present and future generations from systemic economic and ecological harm. Together, these two frameworks form a transdisciplinary legal model that transcends legal formalism by incorporating moral, spiritual, and ecological values into investment governance. The study concludes that national legal reform must adopt an integrative approach to ensure not only legal certainty, but also ethical legitimacy and sustainable public welfare.]]>
