Consumer protection is an important aspect of business law that often clashes with the principle of freedom of contract. This paper analyzes the conflict between Article 18 of the Consumer Protection Law (UUPK) and Article 1320 of the Civil Code (KUHPerdata) in the context of consumer protection in Indonesia. The norm conflict arises mainly in the use of standard clauses in standard contracts, which can harm consumers. John Rawls' theory of justice and Gustav Radbruch's theory of legal certainty are used to understand how the law can balance the interests of consumer protection and freedom of contract. In addition, technological developments and globalization also complicate the application of GCPL in electronic and cross-border transactions. The author suggests several legal strategies to address this conflict, including revision of laws, integration of technology, and harmonization of international law. In conclusion, effective consumer protection requires a balance between substantive justice and legal certainty and adaptation to technological change and market dynamics.
