Background (General): Consent serves as the central boundary distinguishing lawful sexual relations from criminal sexual violence. Background (Specific): For persons with disabilities, assessing consent becomes more complex due to cognitive, mental, physical, or sensory limitations that may affect their ability to understand and communicate agreement. Knowledge Gap: Indonesian criminal law, including the UU TPKS, lacks explicit definitions of consent and standardized indicators for determining consent capacity, unlike jurisdictions such as the United Kingdom and Canada. Aim: This study examines Indonesia’s legal framework on sexual consent and evaluates the absence of consent-capacity standards for persons with disabilities through comparative analysis with UK and Canadian regulations. Results: Findings show that Indonesian law narrowly associates non-consent with coercion or threats, failing to consider cognitive incapacity, whereas the UK (Sexual Offences Act 2003; Mental Capacity Act 2005) and Canada (Criminal Code Section 153.1) provide clear criteria for assessing mental ability, voluntariness, and relational power imbalance. Novelty: This research identifies the structural legal gap in Indonesian consent-capacity regulation and proposes a model grounded in comparative jurisprudence. Implications: The study underscores the urgent need for legal reform to establish explicit consent-capacity standards, strengthening protection against sexual exploitation of persons with disabilities. Highlights: Highlights the absence of explicit consent-capacity standards in Indonesian law. Shows how UK and Canada provide clearer protections through defined legal criteria. Emphasizes the urgency of legal reform to safeguard persons with disabilities from exploitation.
