( 1 ) THIS is a petition by an Association registered under the Bombay Non-Trading Corporations Act. The Respondent No. 1 herein is the Ahmedabad Municipal Corporation and the Respondent No. 2 is the State of Gujarat. The petitioner-Association has various premises constructed on a plot situated on the Ashram Road Ahmedabad. The petitioner-Association had submitted its first plan for construction on that plot and that plan was sanctioned on 1-2-80 and the due commencement certificate was given. Then the revised plan was submitted on 23-3-81 which was rejected 23-6-81 and the second revised plan submitted on 27-12-82 claiming 1-40 F. S. I. (Floor Space Index) was also rejected on 17-2-83. The petitioner alleged that the revised plans had been rejected on the sole ground that the available F. S. I. was 1 and not 1-40 as claimed. The petitioner had therefore ultimately filed this petition for the following prayers to be fouud at page 32: (B) this Honble Court may be pleased to declare the notification dated 12/08/1983 of the Government of Gujarat under the Gujarat Town Planning and Urban Development Act 1976 making provision of F. S.

I. of 1 in Commercial Zone of Ashram Road with effect from 16/09/1983 on a proposal submitted in January 1976 without inviting any objections is clearly illegal null and void and of no effect; (F) this Honble Court may be pleased to direct the Ahmedabad Municipal Corporation to examine the question of permissible F.

S. I and also to act upon the opinions expressed by expert bodies with regard to the permissible F. S. I. on Ashram Road; (I) this Honble Court may be pleased to hold that the State Government and/or the authorities of the Ahmedabad Municipal Corporation are estopped in law and on facts in contending that the permissible FSI on Ashram Road for the period from January 1976 till 16/09/1983 should be I and not 1. 33 1. 5 or 2. 3; (J) this Honble Court may be pleased to direct the State Government and/or the Ahmedabad Municipal Corporation to adopt reasonable standard in the matter of relaxation of FSI for buildings situate on Ashram Road and not to adopt discriminatory and/
