Summarize the following court judgment. N: Criminal Appeal No. 261 of 1976. Appeal by Special Leave from the Judgment and order dated 2 12 1975 of the Andhra Pradesh High Court in Criminal Misc. Petition No. 2064/75. D. V. Patel	 Naunitlal and Miss Kiran Singh for the Appellants. P. P. Rao	 K. Narayan Rao and G. N. Rao for the Respondent. 93 The Judgment of the Court was delivered by JASWANT SINGH	 J. The appellants who are Directors of Tandur and Navandgi Stone Quarries Private Limited and holders of a mining lease for extraction of lime stones (Shahabad Stones) are being prosecuted in the Court of Munsif	 Judicial Magistrate	 First Class	 Tandur	 for the alleged violation of Rule 21 (1)(ii) of the Mineral Conservation and Development Rules	 1958 which is made punishable under Rule 27 of the said Rules in that they failed to employ a qualified geologist or a mining engineer. they made an application before the trial Magistrate urging by way of preliminary objection that the complaint against them was not maintainable in view of the fact that the 'Shahabad Stones ' Which were being extracted by them were used fol. building and construction purposes and as such were minor minerals which were specifically excluded from the purview of the Rules. The Magistrate dismissed the application holding that what was being operated by the appellants was 'a mine for the purpose of the provisions of Rule 21 of the Mineral Conservation and Development Rules	 D	 1958 '. The appellants thereupon moved the High Court for quashing the aforesaid criminal proceedings pending against them reiterating that as the Shahabad Stones which they were extracting were used for building purposes and were described as minor minerals in Item 15 of Schedule I to the Andhra Pradesh Minor Mineral Concession Rules	 1966 (hereinafter referred to as M.M.C. Rules	 1966)	 the complaint against them was not tenable. 'The High Court dismissed the application holding that the inherent powers possessed by it under Section 482 of the Code of Criminal Procedure 1973 could be invoked and exercised only when the facts alleged in the complaint if they are accepted to be correct at their face value	 do not make out an offence with which the accused is charged. The High Court further held that merely because the 'Shahabad Stones ' were included in Schedule I to Rule 10 of the M.M.C. Rules	 it could not be said straightway that the Stones which were being extracted by the appellants were minor minerals and that some evidence regarding their user was necessary for determination of the question as to whether the appellants were entitled to the benefit of the provision of Rule 2 of the M.M.C. & D. Rules which Provided that the M.M.C. Rules do not apply to the minor minerals. It is this refusal of the High Court to quash the proceedings which has given rise to the present appeal. It is now well settled that the High Court does not ordinarily interfere at an interlocutory stage of a criminal proceedings pending in a subordinate Court. Bearing in mind the well recognised principles of law governing the matter and taking into consideration the nature of 94 the impugned order	 we think the High Court was right in declining to grant relief to the appellants. It is also not a matter in which we may legitimately interfere in exercise of our extraordinary powers under Article 136 of the Constitution specially when the case is at its threshold and evidence has still to be adduced as to whether the minerals extracted could or could not be used as a major mineral for certain purposes. It must be realised that it is not possible to determine difficult question of the kind involved in the instant case purely in abstract without relevant evidence bearing on the matter in issue. Accordingly	 we dismiss the appeal. Our order will not	 however	 be interpreted as barring the appellants from raising any defence or contention that may be open to them before the trial court which will dispose of the same in accordance with law uninhibited by any observations made by it earlier or by the High Court in the course of its Order dismissing the application under section 482 of the Code of Criminal Procedure	 1973. S.R. Appeal dismissed.

The trial magistrate dismissed the application and the High Court declined to interfere under Section 48 of the Criminal Procedure Code	 1973. Dismissing the appeal by special leave the Court	 ^ HELD: As the High Court does not ordinarily interfere at an interlocutory stage of a criminal proceedings pending in a subordinate Court	 the A.P. High Court was right in declining to grant relief to the appellants	 bearing in mind the well recognised principles of law governing the matter and taking into consideration the nature of the impugned order. It is also not a matter in which Supreme Court may legitimately interfere in exercise of their extra ordinary powers under article 136 of the Constitution especially when the case at its threshold and evidence has still to be adduced as to whether the minerals extracted could or could not be used as a major mineral for certain purposes. It is not possible to determine difficult question of the kind involved in the instant case	 purely in abstract without relevant evidence bearing on the matter in issue. [93G H	 94A B]
