Final arguments by the Mumbai Metro Rail Corporation (MMRCL) and the Parsi community ended on October 8 in the Bombay High Court, which is hearing a case where Zoroastrian residents of Mumbai are protesting tunnelling for the underground Metro Line 3. The line is expected to run below two of the community's highest seats of worship in the city, the Wadiaji Atashbehram and Anjuman Atashbehram, both at Princess Street.

To prove their comitment to allow infrastructure development to progress, the petitioners — structural engineer Jamshed Sukhadwalla, advocate Zerick Dastur, lawyer Berjis Desai, priest RP Peer, and two others — engaged European tunnelling expert Nicola Della Valle at their own expense through the good offices of Mumbai architect Hafiz Contractor. The concept drawings for eight realignment options, including reducing the proposed Kalbadevi station by 3.5 metres to enable shifting of the up tunnel under JSS Road, were presented.
