Singhal, an aspiring law student, said that the arrests of the Mumbai girls, Shaheen Dhadha and Renu Srinivasan for their Facebook posts left a chilling effect on her and other internet users.
She said section 66(A) was susceptible to 'wanton abuse' in view of the subjective discretion of the police.
"I filed the PIL because I felt that the arrests ... were a gross violation of our right to free speech and expression ensured under the Constitution. I am a Facebook user and I feel a sense of camaraderie with all the people who were arrested," she said.
The Supreme Court on Thursday disapproved of the arrests of two youngsters in Palghar for questioning in their Facebook posts the Mumbai shutdown of November 18 for Sena chief Bal Thackeray’s funeral.
It agreed to hear a PIL seeking scrapping of section 66A of the IT act used for the arrests.
Dhadha, 21, was arrested on November 19 for putting up the post. And her friend, Srinivasan, was detained later for liking it.
“The arrest of two children outraged the conscience of many,” a bench led by CJI Altamas Kabir said after senior advocate Mukul Rohatgi mentioned the petition.
