Indian Constitution - Question and answers

I'm a political science student researching federalism for a term paper. I've read the Seventh Schedule of the Indian Constitution, which lists Union, State, and Concurrent Lists, but I'm struggling to apply this to recent events like the COVID-19 pandemic. For instance, during the lockdowns, both central and state governments issued orders, and it's unclear who had the final authority in areas like health and disaster management.I've reviewed the Disaster Management Act, 2005, and the Epidemic Diseases Act, 1897.I've looked at news articles, but they often contradict each other.I need practical insights or case studies to understand how powers are exercised in such scenarios.

I've been using Gujarati textbooks and online resources, but when it comes to exam questions that involve hypothetical cases, I often mix up which constitutional provisions apply. For instance, in a scenario about environmental protection, I'm unsure whether to prioritize Article 21 (right to life) or the directive principles under Part IV. I've tried creating comparison charts, but still find it confusing during mock tests.
