The Karnataka High Court dismissed Twitter's petition challenging Centre's blocking orders and imposed a cost of ₹50 lakh for the following reasons: 1. Lack of compliance: The court observed that Twitter had not fully complied with the new IT Rules, 2021, which required social media platforms to appoint grievance officers and comply with takedown requests within a specified timeframe. 2. Delay in compliance: The court noted that Twitter had taken a considerable amount of time to appoint a grievance officer in India, which raised concerns about its commitment to adhering to the new rules. 3. Public interest: The court emphasized the need to balance freedom of speech with public interest and national security concerns. It stated that if social media platforms fail to comply with blocking orders related to such concerns, it can have serious consequences. 4. Deterrence: The imposition of a hefty cost was seen as a measure to deter Twitter and other platforms from delaying or avoiding compliance with the law, as non-compliance can affect public order and national security. In conclusion, the court's decision to dismiss Twitter's petition and impose a cost of ₹50 lakh was based on concerns regarding lack of compliance, delay in compliance, and the need to balance freedom of speech with public interest and national security.
