Explanation:

Seat of Supreme Court -The Constitution declares Delhi as the seat of the Supreme Court. But, it also authorises the chief justice of India to appoint other place or places as seat of the Supreme Court. He can take decision in this regard only with the approval of the President. This provision is only optional and not compulsory. This means that no court can give any direction either to the President or to the Chief Justice to appoint any other place as a seat of the Supreme Court.
The SC’s Jurisdiction cannot be Curtailed - The Parliament is not authorised to curtail the jurisdiction and powers of the Supreme Court. The Constitution has guaranteed to the Supreme Court, jurisdiction of various kinds. However, the Parliament can extend the same.
