The Indian government's power to order blocking of content on the internet using Section 69A of the Information Technology Act is incredibly draconian, and has always been ripe for misuse.
There have been attempts over many years to try and challenge the misuse of the law, from a prayer within the Shreya Singhal case (which did lead to the striking down of a different draconian provision, Section 66A), to separate cases like that of satirical dowry calculator website creator Tanul Thakur.
Twitter's arrival on this scene with its petition in the Karnataka High Court against several blocking orders sent to it, however, could be a game-changing moment in the fight to prevent misuse of this law, not least because it is a rare attempt by a corporate entity to stand up to the government on an issue connected with fundamental rights.
