Harshavardhan's first tryst with the RTI (The Right To Information Act - 2005) was when he was denied a passport for over two years, with no valid explanation from authorities. Determined, he filed an RTI application, filed a case in the District Consumer Forum, pursued his case for six months, and finally received his passport. This experience opened his eyes to the power of RTI as a tool for justice, especially for marginalised communities facing systemic issues.

Since then, Harshavardhan has filed hundreds of RTI petitions to address diverse challenges, from withheld loans in government banks and land record statement discrepancies, to unpaid wages for labourers and environmental violations by industries prioritising profit over community well-being.
