6. It appears from the material filed by either side that the 1st respondent-Corporation has found some deviations and therefore, notices were issued. As a consequence to the issuance of notices, it is for the respondent-corporation to take further course of action as warranted by law, after giving due opportunity to the erring building owners. Having regard to the specific assertions of respondents 2 and 3, that no notice was served, which is not seriously disputed, the notice issued under Section 452 of the H.M.C Act, be served on the respondents 2 and 3 within a period of one week. All the above contentions on behalf of respondents 2 and 3 can be raised before the 1st respondent-Corporation and it is expected that the competent authority of respondent-Corporation shall consider all such contentions that may be raised by them. They are also entitled for personal hearing. The respondent-Corporation shall complete the enquiry and finalise the issue with regard to the allegation of unauthorized construction, as expeditiously as possible, preferably within a period of eight (8) weeks from the date of receipt of copy of this order. Till the issue is finalized, the interim order passed by this Court shall continue.
