The BJP government was investigating its political enemies with the intent of subverting democracy and getting absolute and authoritarian control over India.

The Judiciary is protecting the constitution and its principles.

The BJP government openly supports terrorists [1][2] and tries to defame the principles on which the country is based on.

>The Indian government is democratically elected

The BJP government is trying to destroy those very democratic principles. Spying on citizens and journalists and supporting terrorism are just few of the examples. The NSDAP was also democratically elected in 1933. [3]

The state is legally allowed to spy, in fact it is their duty to spy both inside and outside the country.

I do not think a court has any say in it.

> The state is legally allowed to spy

BJP government was misusing this power to spy on its political opponents which is a clear misuse of power and a subversion of the democratic principles.

> I do not think a court has any say in it.

Seems like they do.

That's rather tragic. The judiciary can be reigned in one way or the other by the legislature. Ideally, the country should have a strong executive (like the POTUS) who is accountable to the people instead of the legislature.

Don't know why you were downvoted. That is how separation of powers usually work.

That judges aren't also elected is sometimes a problem, even if they are bound by law. Different countries have different approaches here, the US has its juries, which is an unusual approach compared to other democracies.
