Summarize the following court judgment. No. 522 of 1974. Petition under Article 32 of the Constitution. H. section Marwah for the petitioner. section C. Majumdar	 G. section Chatterjee and Sukumar Basu for the respondent. KRISHNA IYER	 J. The detenu petitioner	 challenges his detention on various rounds but Shri H. section Marwah	 appearing as amicus curiae	 has raised big contentions and small	 some of which do not merit consideration and others need not be dealt with since	 on a short point	 the petition must succeed. The scheme of the (Act No. 26 of 1971) (hereinafter called the MISA	 for short) is in keeping with article 27 of the Constitution and emphasizes the various stages at which there will be consideration of the need for the detention by different authorities	 such as the District Magistrate	 the State Government and	 ultimately	 the Central Government. For the effective exercise of this power a scheme has been built into the statute. 15 5 We are concerned at present with the power to direct release of the detenu. We may extract the provision here : 14(1) Without prejudice to the provisions of section 21 of the 	 a detention order may	 at any time	 he revoked or modified= (b)notwithstanding that the order has been made by a State Government	 by the Central Government."	 With a view to posting the Central Government with the detention and the grounds t herefore	 section 3(4) provides thus : "3. Power to make orders detaining certain persons. (4)When any order is made or approved by the State Government Under this section	 the State Government shall	 within seven days	 report the fact to the Central Government together with the grounds on which the order has been made and such other particulars as in the opinion of the State Government have a bearing on the necessity for the order." (emphasis	 ours) A fair reading of section 3 indicates that the State Government may directly issue an order of detention or	 if it is done by a lesser authority	 approve of such detention order as provided in the statute. Sub section (4) of section 3	 which we have extracted	 obligates the State Government to communicate	 within seven days of the order of detention it makes or it approves	 that fact to the Central Government	 together with the grounds on which the order has been made and other relevant particulars. Even assuming that the order is made by the District Magistrate and is approved by the State Government	 the communication has to be made to the Central Government within the time specified. This procedural mandate is inviolable except on peril of the order being voided. In the present case it is obvious that the detention order was made on November 21	 1972 by the District Magistrate and approved by the State Government on December 2	 1972. It is curious that on the State 's own showing the communication to the Central Government in compliance with section 3(4) of the MISA has been made on December 1	 1972. This date is beyond seven days of the District Magistrate 's order and it could not have been in compliance with the seven days ' spell after the approval by the State Government	 that having been done only a day after the alleged communication to the Central Government. It is thus plain that the State Government before the approval itself was made. Secondly	 if what it communicated was the order of the District Magistrate	 it	 was not sufficient compliance with the statutory requirement. Moreover	 it was beyond the seven	 days ' period. 156 In short	 there has been an infringement of the procedural safeguard. This has	 in several rulings	 held that the liberty of the citien is a priceless freedom	 sedulously secured by the Constitution. Even so	 during times of emergency	 in compliance with the provisions of the Constitution	 the said freedom may be curtailed	 but only in strict compliance with statutory formalities which are the vigilant concern of the Courts to enforce. We have pointed out how in the present case there has been a failure on the part of the State Government to comply with s.3(4). Judicial engineering prevents breaches of constitutional dykes protecting fundamental freedoms. The order of detention is invalid and the detenu is liable to be 	released. The rule is made absolute. Petition allowed.

Section 3 of the 	 indicates that the State Government may directly issue an order of detention or	 if it is done by a lesser authority	 approve of such detention order as provided. Section 3(4) obligates the State Government to communicate	 within 7 days of the order of detention it makes or approves	 that fact to the Central Government	 together with the grounds and other relevant particulars. The procedural mandate is inviolable except on peril of the order being avoided. In the present case	 the order of detention was made by the Dt. Magistrate on November 21	 1972 and the order was approved by the State Government on December 2	 1972. The order was however communicated to the Central Government on December 1	 1972. HELD : There was no strict compliance with statutory formalities and since there has been ail infringement of the procedural safeguard	 the order of detention is invalid. [155H 156A] (a) The communication to the Central Government by the State Government of its approval was not within 7 days after its approval	 as required by section 3(4)	 because	 the approval by the State Government was only a day after the communication to the Central Government. [155G] (b)If what is communicated is only the order of the District Magistrate	 this was not sufficient compliance with the statutory requirement	 and it further was also beyond the 7 days ' period [155 G H]
