( 1 ) THIS is a rule taken out at the instance of the petitioner against the respondent the Ahmedabad Municipal Corporation for an appropriate writ order or direction under Article 226 of the Constitution quashing and setting aside several notices issued by the respondent calling upon the petitioner to demolish and remove that portion of his property coming within the roadline within seven days of the receipt of the notices and to keep the land underneath open. The petition gives rise to a contention which lies in a narrow compass but our decision we are informed and verily believe will affect some other cases of the same nature. The petitioner is the owner of property bearing survey numbers 4225 4225 4224 4224 4224 4222 and 4223 situate in Jamalpur Ward of the city of Ahmedabad. The property is a four-storied building and the petitioner and the members of his family reside in the same. There are four shops on the ground floor of the building. On 22/06/1956 the respondent Corporation issued a notice under sec. 212 (1) (b) of the Provincial Municipal Corporations Act 1949 to be referred to by us hereafter as the Act calling upon the petitioner to show cause why the land bearing the stated survey numbers should not be acquired and removing the structure thereon as the said structure was within the roadline demarcated by the respondent. The petitioner filed his objections to the same challenging inter alia the legality of the notice and the legality of the position of the alleged roadline. Nothing appears to have been done by the Corporation till 20/06/1960 when it issued notices calling upon the petitioner to remove the structure within seven days of the receipt of the same and to clear the space. These latter are the notices which are challenged on this petition. Various contentions have been raised by the petitioner in his petition. His principal contention and one which has been passed before us is that the Commissioner of the respondent Corporation has imposed and demarcated the roadline relied on by the respondent without following the proper procedure laid down in section 210 (1) (b) of the Act. The contention is that the proper procedure required the Commissioner to obtain approval of the Standing Committee of the Corporation before making any change in the existing roadline. It is said that no public notice of the proposal to impose the change in the roadline was issued by the Commissioner by advertising in local newspaper nor was any notice of the proposed change in the roadline put in the street or part of street for which the change in the roadline was proposed to be prescribed. It is further said that no objections were invited to the proposed change in the roadline as required by section 210. Succinctly stated the case of the petitioner is that the Commissioner had no power to impose the change in the roadline complained of by the petitioner and as he admittedly failed to obtain the previous approval of the Standing Committee to the proposed change the notices served on the petitioner are void and inoperative in law and should therefore be quashed by an appropriate writ or order of this Court. It is also the case of the petitioner in the petition that sections 211 and 212 of the Act are ultra vires Articles 19 and 31 of the Constitution. It is unnecessary to give a resume of the petitioners case on this aspect since Mr. A. H. Mehta learned Advocate for the petitioner has not pressed the same before us.

( 2 ) IN opposition to the rule the Commissioner of the respondent Corporation has filed an affidavit in which he has denied the correctness of the contention raised in the petition. According to him the notices issued under section 212 were legal. He has stated in his affidavit that there was and is a roadline upon the building of the petitioner and that the same is legal. To his affidavit he has annexed a sketch to which we shall turn a little latter. Another affidavit has been put in on behalf of the
