According to sources, the charge sheet was filed before a magistrate in Saket court who posted the matter for April 23 for consideration.
Pachauri was accused of sexually harassing a female colleague in 2015. He stepped down as chairperson of the UN Intergovernmental Panel on Climate Change in February last year and proceeded on leave from TERI where he was the director general.
In November, the woman researcher who accused him of sexual harassment quit her job at TERI, alleging she was treated badly. TERI denied the charge.
On February 8, Pachauri was appointed as the executive vice chairman of the organisation. After severe criticism, TERI on February 12 asked him to proceed on indefinite leave.
