Summarize the following court judgment. : Petitions for Special Leave to Appeal (Criminal) Nos. 1090 91 of 1989. From the Judgment and Order dated 8.5.1989 of the Delhi High Court in Misc. Appln. No. 106/89 & 107/1989. U.R. Lalit	 Tushar Shah and B .V. Desai for the Petitioners. J.S. Arora and Satish Agarwala for the Respondent. After filing of the charge sheet the High Court ordered their re arrest by cancelling the bail. The order of 379 the High Court is now under challenge. I do not find any merit in these petitions. But before dismissing	 I wish	 however	 to draw attention to some aspects of the question raised. The facts: On 23 March	 1988 the petitioners were arrested in Bombay by officers of the Narcotic Control Bureau. They were ordered to be produced before the competent Magistrate at New Delhi. They were accordingly produced before the Addi tional Chief Metropolitan Magistrate	 New Delhi. On 29 March	 1988 they were remanded to jail custody till 12 April	 1988. The remand order was subsequently renewed from time to time. On 10 May	 1988 the petitioners moved the Chief Metropolitan Magistrate for bail. When that petition was pending consideration	 the prosecution submitted charge sheet. The charge sheet was filed on 23 June	 1988 for offences under Sections 21	 23 and 29 of the . On July 22	 1988 the petitioners filed an application for bail under Section 167(2) Cr. P.C. on the ground that the charge sheet was filed after the expiry of 90 days of their arrest. On 29 July	 1988 learned Magistrate enlarged them on bail on their furnishing self bonds in the sum of Rupees two lakhs each with two surety bonds in the sum of Rs. 1 lakh each. The efforts of the prosecution to have the bail can celled could not succeed before learned Magistrate. So they moved the Delhi High Court under Section 439(2) read with section 482 of the Cr. In that application	 the nature of the offence committed	 the part played by the accused	 the gravity of the offence etc.	 were all set out. 1t was also stated that since two of the accused were earlier absconding	 the investigation in the case could not be completed within the time frame. The High Court by following the decision of this Court in Raghubir Singh vs State of Bihar	 ; and after considering the material on record cancelled the bail order. The High Court said: "In the present cases	 no doubt an order was passed granting bail because the charge sheet was not filed within the statutory period of 90 days but it was filed on 92 days. 380 There is no doubt that the charge against the respondents is very serious in nature because they are alleged to have entered into a con spiracy to export heroin out of India. The minimum punishment prescribed in such offence is a sentence of 10 years rigorous imprison ment	 and a fine of Rupees one lakh. I am	 therefore	 of the view that the authority re ferred above is fully applicable to the facts of the present case. Respondents are further alleged to have procured services of one H.S. Gala and a lady carrier Manjula Ben who car ried 3 Kg. heroin from India to USA in Novem ber 1987. Therefore it was on the basis of the statements made by those persons in USA that the respondents were arrested in India. I am	 therefore	 of the view that it is a fit case where order of bail should be cancelled. " The question is whether the discretion exercised by the High Court is legally sustainable? Whether the accused have a special right to remain on bail merely because they have been enlarged under proviso (a) to Section 167(2) of the Code? It is not disputed and indeed cannot be disputed that when an accused is granted bail	 whether under proviso (a) to Section 167(2) or under the general provisions of Chapter XXXIII	 the only method by which the bail may be cancelled is to proceed under Section 437(5) or Section 439(2). That is because the person released on bail under the proviso to Section 167(2) shall be deemed to be so released under the provisions of Chapter XXXIII of the Code. Sub section (5) of Section 437 provides: "Any Court which has released a person on bail under sub section (1) or sub section (2) may	 if it considers it necessary so to do	 direct that such person be arrested and commit him to custody." Sub section (2) of Section 439 provides: "A High Court or Court of Session may direct that any person who has been released on bail under this Chapter be arrested and commit him to custody." 381 Under sub section (5) of Section 437	 the Court if it considers it necessary	 direct that the person on bail be arrested and committed to custody. The bail may be cancelled by the Court if it comes to the conclusion that there are sufficient grounds that the accused has committed a non bailable offence and that it is necessary that he should be arrested and committed to custody. This is what this Court observed in Raghubir Singh vs State of Bihar	 ; It was said (at 826): "Where bail has been granted under the proviso to section 167(2) for the default of the prosecution in not completing the investiga tion in sixty days	 after the defect is cured by the filing of a charge sheet	 the prosecu tion may seek to have the bail cancelled on the ground that the accused has committed a non bailable offence and that it is necessary to arrest him and commit him to custody. In the last mentioned case	 one would expect very strong grounds indeed." And said: "The order for release on bail was not an order on merits but was what one may call an order on default	 and order that could be rectified for special reasons after the defect was cured. " An order for release on bail under proviso (a) to Sec tion 167(2) may appropriately be termed as an order on default. Indeed	 it is a release on bail on the default of the prosecution in filing charge sheet within the prescribed period. The right to bail under Section 167(2) proviso (a) thereto is absolute. It is a legislative command and not Court 's discretion. If the investigating agency fails to file charge sheet before the expiry of 90/60 days	 as the case may be	 the accused in custody should he released on bail. But at that stage	 merits of the case are not to be examined. Not at all. In fact	 the Magistrate has no power to remand a person beyond the stipulated period of 90/60 days. He must pass an order of bail and communicate the same to the accused to furnish the requisite bail bonds. The accused cannot	 therefore	 claim any special right to remain on bail. If the investigation reveals that the accused has committed a serious offence and charge sheet is filed	 the bail granted under proviso (a) to Section 167(2) could be cancelled. 382 I examined the material on record. The offences alleged are of serious nature. I am of the opinion that the discre tion exercised by the High Court does not call for any interference. The Petitions	 are	 therefore	 rejected. N.P.V. Petitions dis missed.

The petitioners were arrested on March 23	 1988 and produced before the Chief Metropolitan Magistrate	 who remanded them to jail custody. During the pendency of peti tioner 's application for bail	 the prosecution filed charge sheet on June 23	 1988 for offences under Section 21	 23 and 29 of the . Thereafter	 on the petitioners ' application for bail under Section 167(2) Cr. P.C. on the ground that the charge sheet was filed after the expiry of ninety days of their arrest	 the Magistrate enlarged them on bail. On an application	 under sec. 439(2) read with Section 482 of the Cr. P.C.	 filed by the prosecution for cancella tion of the bail	 stating that since two of the accused were earlier absconding	 the investigation in the case could not be completed within the time frame	 the High court cancelled the bail order. Hence	 the special leave applications by the petitioners. On the question: whether the discretion exercised by the High Court was legally sustainable and whether the accused had a special right to remain on bail merely because they had been enlarged under Proviso (a) to Section 167(2) of the Code	 378 Dismissing the Special Leave Petitions	 HELD: An order for release on bail under proviso (a) to Section 167(2) of the Code of Civil Procedure may appropri ately be termed as on order on default. Indeed	 it is a release on bail on the default of the prosecution in filing charge sheet within the prescribed period. The right to bail under the provision is absolute. It is a legislative command and not Court 's discretion. If the investing agency fails to file chargesheet before the expiry of 90/60 days	 as the case may be	 the accused in custody should be released on bail. At that stage	 merits of the case are not to be exam ined. In fact	 the Magistrate has no power to remand a person beyond the stipulated period of 90/60 days. He must pass an order of bail and communicate the same to the ac cused to furnish the requisite bail bonds. [381E G] The accused cannot claim any special right to remain on bail. If the investigation reveals that the accused has committed a serious offence and charge sheet is filed	 the bail granted under proviso (a) to Section 167(2) could be cancelled under Sections 437(5) or 439(2) of the Code. [381H] In the instant case	 the offences alleged are of serious nature and the discretion exercised by the High Court does not call for any interference.
