This research paper analyses the implementation and impact of the Right to Information (RTI) Act, 2005, in Odisha, India. The RTI Act, a fundamental right under Article 19(1)(a) of the Indian Constitution, seeks to promote transparency, accountability, and good governance by empowering citizens to access information held by public authorities. The study employs a mixed-methods approach, analysing responses from Public Information Officers (PIOs), First Appellate Authorities, and RTI applicants through surveys and interviews. It explores the historical and constitutional foundations of the RTI Act, highlighting its role in upholding democratic principles. Findings reveal the RTI Act's crucial role in curbing corruption, improving service delivery, and empowering citizens. However, implementation challenges persist, including delays, denials, and lack of awareness. The research provides a comparative analysis of RTI implementation across government departments in Odisha, uncovering variations in compliance, response time, and information quality. Additionally, the study examines the role of appellate authorities in safeguarding the RTI Act's principles and ensuring timely redressal. It analyses the impact of judicial pronouncements on strengthening implementation and protecting the constitutional right to information. Based on the research findings, recommendations are offered to enhance the RTI Act's effectiveness. These include capacity building for PIOs, streamlined processes, proactive disclosure, and widespread awareness campaigns. The study also emphasizes the need for continuous monitoring and evaluation to ensure the Act's effective implementation and uphold the constitutional guarantee of the right to information. This research contributes to the existing body of knowledge by providing a comprehensive assessment of the RTI Act's implementation and impact in Odisha, while emphasizing its constitutional significance. The insights and recommendations presented can inform policymakers, practitioners, and civil society organizations working towards strengthening transparency, accountability, and good governance in India.
