That’s not how the law works in India. Any ruling by an Indian court on matters applicable to the entire country will apply to the entire country. There’s only one Supreme Court in India, and it cannot (and in many cases will not) handle all the cases relevant to national interest.

Very helpful! That sounds like this court is similar to the United States district court.

Can I ask: If someone wishes to challenge this decision from a regional High Court, do they petition the India Supreme Court?

Late reply: yes, if someone wishes to challenge a High Court order, they’d typically appeal in the Supreme Court. There are avenues for “review petitions”, but those don’t work well. The backlog of cases across all the courts is really huge.
