Access to Information (ATI) laws are powerful tools by which citizens, journalists, and civil society organisations can obtain information to scrutinise government.

Strong and well-implemented ATI laws are therefore an important prerequisite for accountability and participation, and are one of the cornerstones of a healthy democracy.
