A division bench of Chief Justice Manjula Chellur and Justice GS Kulkarni was hearing a petition filed by the residents of Churchgate in south Mumbai against the cutting of over 5,000 trees to pave way for the metro line.
The court had yesterday restrained the authorities from cutting even a single tree until further orders.
The MMRC had informed the court that it had taken permission from the BMC's Tree Authority department in this regard.
The court said it also wants details of what kind of trees would be cut, how old they are and if they can be restored or replanted elsewhere.
