A bench of Acting Chief Justice Gita Mittal and Justice C Hari Shankar issued the direction while observing that the municipal corporations were responsible for allowing illegal constructions to reach such a stage where nothing can be done about it.
"Can you demolish all the unauthorised constructions in entire east Delhi," the bench asked and added that the area was located in a sensitive seismic zone where an earthquake of even 5 magnitude on the Richter Scale would cause huge loss of life and widespread damage.
The observations of the bench came after the lawyer for one of the corporations alleged that the petitioner was facing extortion charges.
Pulling up the lawyer, the court told him "he becomes an extortionist because he is saying you are not doing your duty. ... If we tell you to file an affidavit on how many properties are there in Delhi which are as per law, can you do that."
The bench directed the corporations to provide the details before the next date of hearing on February 20, 2018.
