Consider the following statements :
In the post-73rd Amendment era, there has to be decentralization of
1. decision-making powers
2. system as a whole
3. judicial powers
4. administrative powers
Which of the above statements are correct?

In the post-73rd Constitutional Amendment era, Panchayati Raj decentralized decision-making powers (1), system as a whole (2), and administrative powers (4) to rural local self-governments. However, judicial powers were not decentralized, as India maintains an integrated and independent judiciary. Therefore, statements 1, 2, and 4 only are correct.
