A) ABSTRACT / HEADNOTE

This landmark constitutional law case challenged the powers conferred under the Travancore Taxation on Income (Investigation Commission) Act, 1124 (Act XIV of 1124 M.E.) in light of Article 14 of the Constitution of India. The Supreme Court ruled on the constitutionality of Section 5(1) of the Act, jurisdiction of High Courts under Article 226, and the legality of investigations extending beyond originally referred assessment years. It interpreted statutory provisions in light of post-Constitutional legal frameworks and reasserted protection under fundamental rights. The judgment struck down ultra vires administrative actions, underscoring procedural propriety and statutory limitation. It also clarified distinctions between mere administrative agents and empowered legal authorities under law.

C) INTRODUCTION AND BACKGROUND OF JUDGEMENT

The legal framework of this case unfolded in the post-independence period, involving statutory continuity from the erstwhile princely state of Travancore. In 1949, the Travancore Taxation on Income (Investigation Commission) Act, 1124 was enacted, modelled on the Indian Taxation on Income (Investigation Commission) Act, 1947 (Act XXX of 1947). The central controversy arose when investigations into the petitioner’s income-tax affairs for 1942 and 1943 were initiated under the Travancore law by a Commission established for the purpose. The subsequent merger of Travancore with Cochin and the advent of the Indian Constitution complicated jurisdictional and fundamental rights aspects. The petitioner challenged both the jurisdiction and the constitutional validity of the investigation extension, especially beyond the years originally authorized under Section 5(1) of the Act. The case evolved into a seminal interpretation of administrative legality under Article 14 and judicial powers under Article 226.

D) FACTS OF THE CASE

A. Thangal Kunju Musaliar, a businessman from Quilon (Travancore), had been assessed for income-tax for the years 1942 and 1943 by the Chief Revenue Authority. The Travancore Taxation on Income (Investigation Commission) Act, 1124, enacted in 1949, created a Commission to investigate cases of substantial tax evasion. His cases were referred as Evasion Cases Nos. 1 and 2 of 1125 under Section 5(1). The State of Travancore-Cochin came into existence in 1949, continuing prior Travancore laws. Post-Constitution, the Centre extended Act XXX of 1947 to the State, and all pending cases were transferred to the Indian Investigation Commission. The petitioner received notice in 1951 that investigations would also cover the period from 1940 to the latest completed assessment year, which he challenged as ultra vires and illegal. The Travancore High Court issued a writ limiting the investigation to 1942 and 1943, and the matter reached the Supreme Court through cross-appeals.

E) LEGAL ISSUES RAISED

i. Whether the High Court under Article 226 could issue a writ against an authorised official appointed under Section 6 of the Act?

ii. Whether the Investigation Commission had jurisdiction to extend the investigation period beyond the specific years 1942 and 1943?

iii. Whether Section 5(1) of the Travancore Act XIV of 1124 is unconstitutional for violating Article 14?

iv. Whether the petitioner’s fundamental rights under Article 14 were violated by retrospective and excessive administrative powers?

F) PETITIONER’S ARGUMENTS

i. The counsels for Petitioner submitted that:

• Respondent 1 lacked legal authority to investigate years not specifically referred under Section 5(1).

• The Government’s orders only referred to the years 1942 and 1943, hence expanding to 1940 and beyond was ultra vires.

• Section 5(1) of the Act was vague and discriminatory, lacking intelligible differentia, and violated Article 14.

• The Commission lacked jurisdiction to initiate suo motu investigations.

• The authorised official was not immune from judicial scrutiny under Article 226 despite being subordinate to Respondent 2.

• The Act was not validly brought into force before July 1, 1949, hence was not an “existing law” within the meaning of Ordinance I of 1124.

G) RESPONDENT’S ARGUMENTS

i. The counsels for Respondents submitted that:

• The High Court lacked jurisdiction under Article 226 against Respondent 2, which operated from New Delhi.

• The scope of investigation logically included all years within the definition in Section 8(2).

• Section 5(1) provided sufficient clarity and basis for rational classification, focusing on substantial evasion during war years.

• The Commission had procedural authority under central laws post integration and constitutional transition.

• The notification bringing the Travancore Act into force from July 22, 1949 was valid and not retrospective.

H) RELATED LEGAL PROVISIONS

i. Relevant Statutes and Articles:

• Article 14 – Right to Equality

• Article 226 – Power of High Courts to issue writs

• Section 5(1) & 6 – Travancore Taxation on Income (Investigation Commission) Act, 1124

• Section 47(1) – Travancore Income-Tax Act, 1121

• Act XXX of 1947, Act XXXIII of 1950, Act XLIV of 1951

I) JUDGEMENT

a. RATIO DECIDENDI

i. The High Court has jurisdiction under Article 226 to issue writs against officers located within its territorial limits. The authorised official, even if subordinate to a Central Commission, is not immune from writ jurisdiction if his actions violate law or fundamental rights.

ii. The Commission lacked authority to investigate beyond 1942 and 1943, as only these years were referred via Government order under Section 5(1). The expansion of scope was illegal and without jurisdiction.

iii. Section 5(1) did not violate Article 14. It targets a different class of persons – those where no definitive information existed but where prima facie belief of substantial evasion during war years was formed. This is distinct from Section 47(1) cases where specific evasion had already been discovered.

b. OBITER DICTA 

i. The Court emphasized that High Courts under Article 226 should be functional protectors of fundamental rights and cannot be restricted merely because the superior authority lies outside territorial limits.

c. GUIDELINES 

• Writ jurisdiction can apply to subordinate officials located within the State even if acting under an external authority.

• Investigations under Section 5(1) are bound strictly by the scope of reference by Government and cannot be extended suo motu.

I) CONCLUSION & COMMENTS

This ruling reaffirmed judicial safeguards under Article 226 and enforced substantive limits on administrative power under tax law regimes. It drew a critical line between procedural excess and constitutional legality, shielding citizens from indefinite or arbitrary extension of investigatory mandates. The judgment also clarified that mere government suspicion cannot bypass procedural jurisdictional limits. The validation of Section 5(1) under Article 14, by highlighting its rational classification, reflects judicial respect for legislative intent, while still requiring strict procedural compliance.
