Here's part of the "State judiciary" section of Languages with official status in India:

It sounds like these four states said basically "Instead of using Hindi, we'd like to use Hindi." Is that really what this is saying, and if so, what's the point? Or have I misunderstood something? Nyttend (talk) 13:00, 6 October 2018 (UTC)[reply]

I'm fairly sure that what it's actually saying is that the states are saying instead of using English, we'd like to use Hindi. See also the first paragraph in Languages with official status in India#Judiciary. Without obtaining authorisation, the states default to English in their High Courts. They are able to use Hindi or the state's official language, but only if they get the necessary permissions etc. In those four cases they asked for permission to use their official languages which are Hindi although I'm not sure if the process is structured that it's actually clear which one they are requesting.

[1] says something similar. Maybe Judiciary of India and List of high courts in India will also be of interest to those unfamiliar with how things are in India. Note that the organisations of courts is somewhat different from the clearly delineated separate state level and federal (or central/union) level entities as in the US.

And your findings are reinforced by the article's "Judiciary" section. My apology for misunderstanding; somehow I'd misread something to indicate that Hindi was the default language of the courts. Nyttend (talk) 21:17, 6 October 2018 (UTC)[reply]
