Going by this letter of law, gatherings per se can, indeed, cause ‘annoyance’ to ‘any person’ and be the source of ‘disturbance of public tranquillity’. By this reading, protests, even in a democratic space, are up for subjective hyper-scrutiny and cherry-picking. In other words, every protest can be deemed unlawful if the authorities choose to see it as being so.
By their very nature, ‘peaceful’ public protests are disruptive, anti-status quo-ist. For the allowance of such a democratic right to have any practical meaning, it would be wise to be more specific and detailed in law to define what amounts to ‘annoyance’ and ‘disturbance of public tranquillity’. All protests don’t take place in ‘Tiananmen Squares’. And they certainly don’t amount to challenging the ‘welfare of the sovereignty and integrity of India, the security of the State’.
