The Judgment of the Court was delivered by SHAH	 J. This is an appeal filed with a certificate granted under article 133(1)(c) of the Constitution by the High Court of Judicature of the State		 of Hyderabad. The appellant was a Jagirdar holding jagirs Ramwarm Chandam Palli and Gulla Palli	 Taluq Sirsalla	 in the District of Karimnagar in the State of Hyderabad. After the Police Action in August	 1948	 Major General Chaudary was appointed the Military Governor for the State of Hyderabad. His Exalted Highness the Nizam of Hyderabad invested the Military Governor with authority to administer the State by a Farman dated September 19	 1948. The Farman was in the following terms: " Whereas the General Officer Commanding in Chief Southern Army has appointed Major General J. N. Chaudary	 O.B.E.	 to be the Military Governor for the Hyderabad State and whereas all authority 313 for the administration of the State now vests in him	 I hereby enjoin all the subjects of the State to carry out such orders as he may deem fit to issue from time to time. I appeal to all officers of the State administration and subjects of the State to render faithful and unflinching obedience to the Military Governor and conduct themselves in a manner calculated to bring about the speedy restoration of law and order in the State ". On August 7	 1949	 His Exalted Highness the Nizam issued an explanatory Farman in the following terms: " With reference to my Farman dated 19 9 1948	 in which I referred to the fact that all authority for the administration of the State now vests in the Military Governor	 I hereby declare that the said authority includes and has always included authority to make Regulations ". On August 10	 1949	 the Military Governor promulgated The Hyderabad (Abolition of Jagirs) Regulation of 1358 Fasli	 which will hereinafter be referred to as the Abolition Regulation. This Regulation was brought into force on August 15	 1949	 the date of its publication in the Official Gazette. Section 5 of the Regulation directed that from a date to be notified for the transfer of the administrations of the jagirs in the State to the Government	 the jagirdars shall make over the management of the jagirs to the Jagir Administrator and in default of compliance therewith the Officer appointed under the Regulation may take forcible possession. By section 6	 it was provided that the jagirs shall be included in the " Diwani " and unless and until included in a district	 shall be administered by the Jagir Administrator	 and that the powers	 rights and liabilities in relation to such jagirs shall cease to be exercisable by the jagirdars and shall be exercisable by the Jagir Administrators	 and that no jagirdar shall recover or receive any customary or other dues from any tenant or resident of the jagir. By section 14	 it was declared that the jagirdars were to receive certain interim maintenance allowances until such time as the terms of the commutation of the jagirs were determined. Pursuant to the authority reserved by a. 6 of the Abolition Regulation	 possession 314 of the jagirs was taken over sometime in September 1949 by the Jagir Administrator acting on behalf of the State of Hyderabad. On December 1	 1949	 another Farman was issued by His Exalted Highness the Nizam which provided as follows: " Whereas the General Officer Commanding in Chief Southern Army has as from the 1st December	 1949	 terminated the appointment of Major General Chaudary	 O.B.E.	 to be the Military Governor for the Hyderabad State; And whereas it is necessary to make other arrangements for the administration of the State as from the said date; Now	 therefore	 I hereby appoint as from the said date Mr. M. K. Vellodi	 C.I.E.	 I.C.S.	 to be my Chief Minister and . I further direct that all the powers of administration	 vested in the Military Governor before the said date are exercisable by the Chief Minister ". In exercise of the powers vested in him	 the Chief Minister promulgated the Hyderabad Jagirs (Commutation) Regulation No. XXV of 1359 Fasli which will hereinafter be referred to as the Commutation Regulation. This Regulation was brought into operation on January 25	 1950. By section 3 of the Regulation	 the method of computing the commutation sum for every jagir was prescribed. After the inauguration of the Constitution of India on January 26	 1950	 on which date the ' territory of the State of Hyderabad became part of the Union of India	 the President on April 25	 1950	 certified the two Regulations under article 31(6) of the Constitution by a notification published in the gazette of the Union of India. The Constitution was amended on June 18	 1951 by the Constitution (First Amendment) Act of 1951 whereby	 inter alia	 articles 31(A) and 31(B) and Sch. IX were incorporated in the Constitution. The Abolition Regulation and the Commutation Regulation were included in Schedule IX and by virtue of article 31(B)	 neither the Regulations nor any of the provisions thereof were to be deemed to be void or ever to have become void on the ground that the 315 Regulations were inconsistent with or took away or abridged any of the rights conferred by any of the provisions of Part III of the Constitution. In the meantime	 the appellant had	 on January 29	 1951	 filed a petition in the High Court of Hyderabad for a writ in the nature of mandamus directing the State of Hyderabad and the Jagir Administrator to hand over possession of the appellant 's properties and for an order declaring the Abolition Regulation and the Commutation Regulation ultra vires and unconstitutional and for certain interim orders. After the amendment of the Constitution	 the petition was amended on August 14	 1952. By this petition	 the appellant claimed that sections 4(1)(c) and 4(2) of the Commutation Regulation and section 6(4) of the Abolition Regulation were invalid because by these provisions	 there was " naked confiscation of the property " of the appellant and that they amounted to " colourable and fraudulent exercise of legislative power ". The High Court of Hyderabad rejected the petition filed by the appellant	 but certified the case under article 133(1)(c) as a fit one for appeal to this court. In this appeal	 two principal contentions fall to be determined	 viz.	 (1) whether legislative authority was conferred upon the Military Governor by the Farman dated September 19	 1948 and (2) If	 by the Farman	 legislative authority was delegated to the Military Governor	 whether it was circumscribed by any limitations or reservations. Was the Military Governor	 by the Farman dated September 19	 1948	 invested with all the sovereign authority legislative	 executive and judicial of H.E.H. the Nizam or was he merely invested with the executive authority ? By the plain words used in the Farman	 " all authority for the administration of the State was conferred upon the Military Governor" and there is nothing in the text of the Farman which warrants the view that only executive authority was intended to be delegated thereby. Within the expression	 " all administrative authority " is encompassed the entirety of the authority of the sovereign	 and by the delegation from His Exalted Highness the Nizam	 the Military Governor was invested with that authority 316 in all its amplitude. The injunction to the subjects of the State to carry out all such orders as the Military Governor may deem fit to issue and the appeal to the officers of the State and the subjects to render faithful and unflinching obedience and to conduct themselves in a manner calculated to bring about the speedy restoration of law and order	 do not detract from the amplitude of the powers delegated to the Military Governor. The expression	 " orders " would include every order made in exercise of authority for the administration of the State; and the object intended to be achieved	 viz.	 the speedy restoration of law and order in the State by His Exalted Highness the Nizam as expressed in the appeal was not restrictive of that authority. That His Exalted Highness the Nizam in and before the month of September	 1948	 was an absolute ruler invested with all authority	 executive	 legislative and judicial is indisputable. He had supreme powers vested in him to modify	 restrict take away or extinguish the rights of any of his subjects and the validity of his actions or orders was not liable to be questioned before any tribunal or authority. The Farman promulgated on September 19	 1948	 by His Exalted Highness the Nizam delegated his sovereign authority to the Military Governor and to remove all doubts as to the effect of that delegation	 an explanatory Farman dated August 7	 1949	 was issued. It was declared in express terms by that Farman that the authority of the Military Governor to; included and has always included the authority to make Regulations ". In the clearest terms	 the author of the Farman proclaimed the content of the authority delegated by him to the Military Governor. The plea rather faintly urged by Mr. Varma that the Farman merely recited that the Military Governor had been invested with authority for administration and did not by its own force purport to invest the Military Governor with authority to administer the State is plainly inconsistent with the argument which was advanced in the High Court and the statement of the case filed in this court and was therefore rightly abandoned by him. 317 Though by the delegation of authority	 the Military Governor was invested with all authority of His Exalted Highness the Nizam in the matter of administration of the State in all its departments	 the sovereignty of His Exalted Highness the Nizam was	 by this act of delegation	 undoubtedly not extinguished. It was open to him	 notwithstanding the delegation	 to issue orders or Regulations contrary to those which were issued by the Military Governor	 and also to withdraw the authority of the Military Governor. There is	 however	 no evidence on the record to show that after September 19	 1948	 and before the Abolition Regulation was promulgated	 the authority of the Military Governor was withdrawn or that His Exalted Highness the Nizam had issued any order or Regulation inconsistent with the Abolition Regulation. The authority of the Military Governor was withdrawn in December	 1949	 and the Chief Minister was invested with the same authority of administration including expressly the power of legislation	 and it was in exercise of that authority that the Chief Minister issued the Commutation Regulation. The authority of His Exalted Highness the Nizam as the sovereign ruler to resume the jagirs and to extinguish the interests of the jagirdars being by delegation vested in the Military Governor	 the legality of the action of the latter was not open to challenge on any test of legislative competence. Assuming that no opportunity had arisen for exercise of the sovereign authority in the matter of resumption of jagirs or extinction of the jagirdars ' interests before the promulgation of the Abolition Regulation	 an inference cannot therefrom arise that His Exalted Highness the Nizam had irrevocably placed a restriction on his sovereignty	 or that the delegation to the Military Governor of the sovereign authority was subject to an implied restriction that the interests of the jagirdars in the jagirs could not in exercise of the authority be extinguished. The authority of the Military Governor	 being unrestricted	 so long as it enured	 his action in issuing the Abolition Regulation could not be challenged on the plea that it was a colourable exercise of legislative 41 318 authority. The doctrine of invalidity of legislative provisions enacted in colourable exercise of authority applies to legislatures whose powers are subject to constitutional restrictions. When such a legislative body seeks	 under the guise or pretence of complying with the restrictions	 in enacting a statute	 to evade or elude them	 it is but a fraud on the Constitution	 and the statute is liable to be declared invalid on the ground that the enactment is in colourable exercise of authority	 the statute being in truth beyond the competence of the body. But a statute enacted by a legislative authority whose powers are not fettered by any constitutional or other limitations	 cannot be declared invalid as enacted in colourable exercise of its powers. The authority of the Chief Minister under the Farman dated December 1	 1949	 in its amplitude	 was as extensive as that of His Exalted Highness the Nizam and the Commutation Regulation was not liable to be challenged on the ground of want of legislative competence or colourable exercise of legislative authority	 the power exercised by him being the legislative power as the delegate of the Sovereign. The plea that the fundamental rights of the appellant under the Constitution were infringed by the two Regulations does not require any detailed examination. By virtue of the Abolition Regulation	 the rights of the appellant as a jagirdar in his jagir were extinguished and by the Commutation Regulation	 the quantum of compensation payable to him was determined by a pre Constitution legislation. The Regulations were competently promulgated in exercise of legislative authority in that behalf ; and the Constitution does not operate retrospectively to revive the rights which had been	 before it was enacted	 extinguished. The Constitution has except as otherwise expressly provided	 no retrospective operation Keshavan Mahava Menon vs State of Bombay (1); and rights which were by legislation extinguished	 before it was enacted	 are not revived thereby. At the commencement of the Constitution	 the appellant had	 therefore	 no rights in the jagirs and he	 obviously	 could not claim a writ of mandamus directing (1) ; 319 delivery of possession of the jagir	 or a writ directing commutation otherwise than under the provisions of the Commutation Regulation. It may also be observed that the Parliament has	 by the Constitution (1st	 Amendment) Act	 included the Abolition and the Commutation Regulations in the ninth schedule	 and by virtue of article 31(B)	 the two Regulations are exempt from challenge on the ground that they are inconsistent with or take away or abridge any of the fundamental rights conferred by Part III of the Constitution. The appeal therefore fails and is dismissed with costs. Civil Appeal No. 686 of 1957. This appeal raises the same question which has been decided in the companion Appeal No. 392 of 1956 and for reasons set out therein	 this appeal must fail and is dismissed with costs. Appeals dismissed.

After the Police action in the State of Hyderabad in August	 1948	 the Nizam	 by a Farman dated September 19	 1948	 invested the Military Governor " with all authority for the administration of the State " and by a later Farman declared that " the said authority includes and has always included authority to make Regulations." By virtue of the said powers	 the Military Governor promulgated the Hyderabad (Abolition of jagirs) Regulations of 1358 Fasli. Thereafter on the termination of the appointment of the Military Governor	 the Nizam by another Farman appointed Mr. Vellodi as his Chief Minister and directed that " all the powers of administration	 vested in the Military Governor before the said date are exercisable by the Chief Minister. " Thus empowered	 the Chief Minister promulgated the Hyderabad jagirs (Commutation) Regulation XXV of 1358 Fasli. Thereafter with the commencement of the Constitution of India	 the territory of the State of Hyderabad became part of the Union of India and the President certified the two Regulations under article 31(6) of the Constitution. By the Constituion (First Amendment) Act of 1951	 articles 31(A) and 31(B) and Sch. IX were inserted into the Constitution and the two Regulations were included in the said schedule. The appellant	 whose properties had been taken over by the jagir Administrator under the Abolition Regulation	 and who had	 in the meantime	 filed a writ petition in the High Court	 by his amended petition after the amendment of the Constitution	 claimed that sections 4(1)(c) and 4(2) of the Commutation Regulation and section 6(4) of the Abolition Regulation were confiscatory in nature and amounted to colourable and fraudulent exercise of legislative power. The High Court found against him and rejected his petition: Held	 that the decision of the High Court must be affirmed. There can be no question that the Nizam	 at the time when he executed the Farmans and prior to it	 was an absolute ruler vested with all authority executive	 legislative and judicial and had unquestionable powers to modify or extinguish any of the rights of his subjects and the language of the Farmans leaves no manner of doubt that he thereby delegated the entirety 312 of his authority and powers to the Military Governor and thereafter to the Prime Minister. The doctrine of invalidity of legislation enacted in colourable exercise of legislative authority can apply only where the legislature is subject to constitutional restrictions. But where the powers of the legislature suffers from no limitations	 constitutional or otherwise	 that doctrine can have no application. No question of infringement of fundamental rights could arise as (i) the impugned Regulations were pre Constitution legislations and the appellant 's rights had already been determined before the Constitution	 (ii) article 32(B) of the Constitution exempts the Regulations from such a challenge.
