As noted herein above, even though notification under Section 4 (1) of the Act was issued as far back as 06-03-2007, the petitioner remained quiet till 21-10-2012, when, for the first time, he has filed WPMP.No.42933 of 2012 for impleadment in WP.No.6780 of 2008 filed by respondent Nos.3 and 4 challenging the acquisition proceedings. As noted above, even in the said Writ Petition, he has not raised any pleading relating to validity of acquisition. When WP.No.6780 of 2008 was sought to be withdrawn, no objection was raised on behalf of the petitioner for its withdrawal. All these facts would suggest that the petitioner had no intention of questioning the acquisition proceedings atleast till he has filed the implead petition in the year 2012, for as many as 5 years. The petitioner has not convinced this Court that he is diligent in pursuing his cause relating to acquisition proceedings. The petitioner cannot be permitted to challenge the acquisition proceedings at his leisure after efflux of substantial time. The learned Counsel for the petitioner submitted that in respect of the western side of the proposed road, two Writ Petitions are pending and that this Writ Petition may also be heard along with the said Writ Petitions. I am unable to accept this request as he has failed to offer convincing reasons for not approaching this Court within reasonable time.
