The Bombay High Court on Wednesday refused to grant any relief to stock brokers challenging a demolition order passed by the Brihanmumbai Municipal Corporation (BMC) on certain illegal structures inside the Bombay Stock Exchange (BSE) building in Mumbai.A PIL in this regard was filed by Aditya Srinivas and several other brokers who challenged the May 28, 2013 notice and June 21, 2013 order passed by the civic body asking BSE to raze illegal structures constructed on a podium terrace and three service floors in its building, also known as P J Tower. The PIL sought for a direction to BSE to approach the corporation for regularisation of unauthorised constructions. The court said if BSE's petition had been dismissed then nothing much can be done in this PIL and posted the petition for March 14.
