This research explores the use of English for Specific Purposes (ESP) in constitutional law classes at Institut Parahikma Indonesia (IPI) Gowa, focusing on the role of English language skills in the legal field. Many law students face difficulties in understanding legal terms and language structures. This study aims to connect language and law through ESP-based classroom activities and evaluate their impact on students' language skills and legal understanding. The respondents in this study were six first-semester students from the Constitutional Law Study Program at IPI in the 2024/2025 academic year, as well as lecturers teaching English courses. By using qualitative methods, the researchers collected the data through observations and interviews. The results showed that activities such as trial simulations helped improve students' legal knowledge and communication skills while building their confidence in using English professionally. However, the study also identified challenges in implementing ESP effectively, particularly in aligning teaching materials with students' needs. This highlights the importance of collaboration between educators and legal experts in developing a relevant curriculum. Overall, this research underscores the value of creative ESP teaching in preparing students for legal careers.
