21.The object of letting out the shops is to collect more revenue for the respondent-Municipality, which is meant to be used for welfare measures. The Government Orders, as narrated above, are very specific about the purpose of auction followed by lease/licence. Since the transactions are commercial in nature, the petitioners, being licensees, cannot insist that the rent, which as they think, just and proper alone is liable to be paid. Since the licence is to be granted by the respondent- Municipality, while making offer, the said authority can impose its own terms in accordance with law. While accepting the said offer, the petitioners cannot insist that the condition attached therein cannot be imposed. A perusal of the Government Orders referred to above as well as the orders impugned make it clear that the rent has been fixed based upon the prevailing market value and not otherwise. What has been given by way of extension to an existing licensee was only a concession. The subsequent extension has been made during the pendency of the writ petitions. The said decision was made in view of the undertaking given by the licensees. An undertaking was given in connection with the payment as well as on the withdrawal of the writ petitions. The Government orders also state that in the event of non compliance of the conditions imposed including the payment of appropriate rent, a licensee is liable to be removed.
