What is the case under which UNI's office was sealed in Delhi?

The office of the United News of India (UNI) in Delhi was sealed on March 20 following a Delhi High Court order that upheld the cancellation of its land allotment. The cancellation in March 2023 came after UNI failed to build the office complex on the plot for over 45 years, since 1979. UNI had filed a petition against cancellation.
