In its petition filed before the High Court, Twitter contended that account-level blocking is a disproportionate measure and violates the rights of users under the Constitution.
The petition stated that the orders in question were manifestly arbitrary, and procedurally and substantively not in consonance with Section 69A of the IT Act.
Further, they fail to comply with the procedures and safeguards prescribed by the Information Technology (Procedure and Safeguards for Blocking for Access of Information by Public) Rules, 2009 (Blocking Rules), it was submitted.
Twitter also argued that the direction to block entire accounts falls afoul of Section 69A of the IT Act.
