Learned counsel for the petitioner submits that the construction of residential complex was undertaken in accordance with municipal sanction plan No.385/TPS/92 dated 09.10.1992. The members of petitioner association are owners of residential flats and also undivided share in the extent covered by door numbers referred above. The 1st respondent cannot, on the representation of respondents 4 to 6, who do not have exclusive or independent interest in the subject premises, sanction plan etc., take up relaxation of regulation, much less grant exemption to respondents 4 to 6 for conversion of alleged surplus parking space into shop rooms. The further submission of learned counsel for the petitioner is that respondents 1 to 3 cannot, in law, ignore the commonality of interest of owners of residential complex, the effect of sanction plan dated 09.10.1992 and arbitrarily grant conversion of stilt for commercial activity. Any request of respondents 4 and 5 firstly cannot be considered within the four corners of law and secondly if respondents 1 to 3 consider the request for relaxation, the same shall not be without notice to the petitioner association or individual flat owners. On the short ground that the impugned GO is illegal and violative of principles of natural justice, the learned counsel prays for setting aside the same.
