The Right to Information (RTI) Act 2005 aims to promote transparency and accountability in public authorities by allowing citizens access to information held by them. Enacted on June 15, 2005, it sets procedures for requesting information, outlines the roles of public authorities, and establishes the Central and State Information Commissions for oversight and appeals. The Act defines key terms such as 'information' and 'public authority,' and lists provisions for fees, processes for dealing with information requests, and exemptions for certain types of information.
