The woman drank poison at the city court in Ahmedabad, Gujarat, and was rushed to hospital, where doctors said she is not in a critical condition.
She alleges her employer and his friends raped her at a garment factory where she worked in 2007 and that the police refused to file the case when she first reported it.
The police maintained that her allegations were false – a defence rejected by the court in 2010, NDTV reported.
A fresh inquiry was launched and the woman’s medical file requested, only for the case to be adjourned until next month.
