first respondent had granted permission, the previous landlord constructed and completed the temporary shed, but subsequently, the first respondent had rejected the planning permission application on 28.08.2002 stating that the construction did not comply with the CMDA rules. Subsequently, the sixth respondent continued further construction, without getting permission from the previous landlord and without any planning permission from the competent authority. Therefore, the previous landlord himself had given a complaint to the first respondent about the un-authorised construction made by the sixth respondent. Subsequently, the petitioner purchased the property on 14.02.2006. In spite of insistence made by the petitioner, the sixth respondent refused to demolish the illegal construction of temporary shed and has been continuing his business operation in the same building, which was constructed without proper planning permission.
