JUDGMENT

After hearing Smt. Kitty Kumarmanglam, 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-cl. (ii) of the proviso to Cl. (b) of sub-s. (1) of S. 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 mine and the number of persons employed on any one day exceeded 50. That being so, the respondents fell within the mischief of the proviso to Cl. (b) of S. 3(1) of the Act and became subject to the provisions of the Act. The Inspector was therefore well within his powers to serve a notice under S. 22 read with S. 17 of the Act calling upon the respondents to appoint a qualified Manager for the mine. The High Court on an erroneous interpretation of the word and occurring at the end of paragraph (b) of sub-cl. (ii) of the proviso to Cl. (b) of sub-s. (1) of S. 3 of the Act held 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 Act, 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 S. 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-s. (1) of S. 3 of the Act provides that the provisions of the Act, except those contained in Ss. 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 lime stone. 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 Act would be made applicable to such a mine. The provision of sub-s. (1) of S. 3 of the Act insofar as relevant for purposes of this case reads as follows :

"3. Act not to apply in certain cases - (1) The provisions of this Act, 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, china clay, white clay or fire clay), building stone, road metal, earth, fullers earth and lime stone:

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-s. (1) of S. 3 of the Act read with the two provisos beneath clauses (a) and (b), the word and at the end of paragraph (b) of sub-cl. (ii) of the proviso to cl. (b) of S. 3(1) must in the context in which it appears be construed 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) of sub-s (1) of S. 3 and thereby make the mine subject to the provi
