1. After hearing Smt. Kitty Kumarmangalam, learned counsel for the appellant and Shri A. Subba Rao, learned counsel for the respondents, we are inclined to the view that the High Court was not right in its interpretation of the word and used at the end of paragraph (b) of sub-clause (ii) of the proviso to clause (b) of sub section (1) of Section 3 of the Mines Act, 1952 as being conjunctive.

2. In the present case, admittedly the respondents are engaged in working an open cast mine. After an inspection, the inspector of Mines found that the respondents were engaged in the open cast mining and the number of persons employed on anyone day exceeded 50. That being so, the respondents fell within the mischief of the proviso to clause (b) of Section 3(1) of theand became subject to the provisions of the. The Inspector was therefore well within his powers to serve a notice under Section 22 read with Section 17 of thecalling upon the respondents to appoint a qualified manager for the mine. The High Court on an erroneous interpretation of word and occurring at the end of paragraph (b) of sub-clause (ii) of the proviso to clause (b) of the proviso to clause (b) of sub-section (1) of Section 3 of theheld that the use of the word and made the three paragraphs conjunctive and unless the conditions specified in paragraphs (a), (b) and (c) co-existed, the Inspector had no authority to serve the impugned notice. It accordingly allowed the writ petition filed by the respondents and quashed the impugned notice.

3. In order to appreciate the point involved, it is necessary to refer to a few statutory provisions. The object and purpose of the, as reflected in the long title, is that it is an Act to amend and consolidate the law relating to the regulation of labour and safety in mines. By Section 2(h) of the Act, a person is said to be employed in a mine who works under appointment by or with the Knowledge of the manager, whether for wages or not, in any mining operation. Sub-section (1) of Section 3 of theprovides that the provisions of the, except those contained in Sections 7, 8, 9, 44, 45, and 46 shall not apply to (a) any mine or part thereof in which excavation is being made for prospecting purposes only and not for the purpose of obtaining minerals for use or sale, (b) any mine engaged in the extraction of any of the minerals specified therein, including limestone. There is a proviso under each of the clauses (a) and (b) and they set forth three conditions on the happening of any one of which the proviso would be attracted, that is to say, the provisions of the would be made applicable to such a mine. The provision of sub-section (1) of Section 3 of theinsofar as relevant for purposes of this case reads as follows:

"3. Act not to apply in certain cases. - (1) The provisions of the, except those contained in Sections 7, 8, 9, 44, 45 and 46 shall not apply to -

(a) * * *

(b) any mine engaged in the extraction of kankar, murrum, laterite, boulder, gravel, shingle, ordinary sand (excluding moulding sand, glass sand and other mineral sands), ordinary clay (excluding kaolin, chine clay, white clay or fire clay), building stone, road metal, earth, fullers earth and limestone

Provided that -

(i) * * *

(ii) where it is an open cast working -

(a) the depth of the excavation measured from its highest to its lowest point nowhere exceeds six meters

(b) the number of persons employed on any one day does not exceed fifty; and

(c) explosives are not used in connection with the excavation."

4. According to the plain meaning, the exclusionary clause in sub-section (1) of Section 3 of theread with the two provisos beneath clauses (a) and (b), the word and at the end of paragraph (b) of sub-clause (ii) of the proviso to clause (b) of Section 3(1) must in the context in which it appears, be constructed as or; and if so construed, the existence of any one of the three conditions stipulated in paragraphs (a), (b) and (c) would at once attract the proviso to clauses (a) and (b) sub-section (1) of Section 3 and thereby make the mine subject to the provisions of the. The High Court overlooked the fact that the use of the negative language in each of the three clauses implied that the word and used at the end of clause (b) had to be read disjunctively. That construction of our is in keeping with the legislative intent manifested by the scheme of the which is primarily meant for ensuring the safety of workmen employed in the mines.

5. We accordingly allow the appeal, set aside the judgment of the High Court an dismiss the writ petition. However, it was represented by learned counsel for the respondent that it is difficult to find a duly qualified person to come and serve as manager of a mine in rural areas and we should call upon the appellant to find a suitable person for appointment as manager. Learned counsel for the appellant was however gracious enough to suggest that the department will find a qualified person and depute him to work as manager, and the respondents shall be liable to pay his salary and allowances as may be stipulated by the Joint Director of Mines Safety. The Joint Director will select and depute a proper person to serve as manager of the respondents mine within thirty days from the receipt of this order.

6. In view of this, the appellant will consider the feasibility of not launching a prosecution against the respondents for their past failure to appoint a duly qualified manager as required under Section 17 of the Mines Act, 1952.
