ContentsCase note & sources

Facts and procedural history

The appellants imported cellular phones and textile goods. They had enjoyed sales-tax exemptions granted by the Federal Government.

Three notifications withdrew exemptions or changed rates:

  • 280(I)/2013: cellular phones, 4 April 2013.
  • 460(I)/2013: cellular phones, 30 May 2013.
  • 682(I)/2013: textile goods, 26 July 2013.

They were issued under sections 3, 4(c), 8, 13 and 71 of the Sales Tax Act, 1990. Challenges in the Islamabad High Court, including intra-court appeals, failed.1

The Supreme Court addressed a narrower question: had the legally authorised institution made the decision?

Fiscal officials had issued the notifications without a Cabinet decision. One preceded an Adviser to the Prime Minister’s approval, which was given after the event.

For this challenge, everything else about the notifications was assumed to be in order.2

Issues

  1. Who is the Federal Government under Articles 90 and 91?
  2. Does allocating departmental work, or authorising a signature, also confer the underlying power to decide?
  3. Could these fiscal notifications issue without prior Cabinet consideration and approval?3

Holding

The Federal Government means the Cabinet acting collectively: the Prime Minister and Federal Ministers.

Where legislation assigns a power to that body, an individual officeholder cannot exercise it in the Cabinet’s place.

The Rules of Business were binding. The fiscal proposals required prior Cabinet consideration. Authentication established a document’s genuineness; it did not supply missing decision-making power.

The Court accordingly held the challenged notifications invalid.4

Articles 90 and 91

Composition of the Federal Government

Prime MinisterHeads the Cabinet
Federal MinistersAct collectively
Federal GovernmentAccountable collectively to Parliament

A single officeholder is not a substitute for the whole institution.

Reasoning

The constitutional decision-maker

The Court read Article 90 together with Article 91. The Prime Minister and Federal Ministers act collectively, and the Cabinet is collectively responsible to Parliament.

Executive authority is exercised in the President’s name. That formal position does not transfer the Cabinet’s constitutionally assigned authority to the President.5

Allocation of functions

Departmental processing, Cabinet approval and authentication

  1. DepartmentPrepare

    Develop the policy and process the proposal.

  2. CabinetDecide

    Exercise the power assigned to the Federal Government.

  3. Authorised officialAuthenticate

    Establish the instrument’s genuineness, without conferring substantive decision-making power.

Mustafa Impex · paras 60–63

The Rules of Business

Article 99 provides the machinery for conducting government business. The executive is bound by the Rules of Business it makes.

Rule 16 required Cabinet consideration of proposals concerning the levy, abolition, remission, alteration or regulation of tax.

Failure to obtain Cabinet consideration was a defect of legal authority, not merely a procedural irregularity.6

Processing, approval and authentication

The Revenue Division could process fiscal policy. A secretary could authenticate an instrument. Neither function conferred the substantive power to decide.

Under Rule 7(2), authentication was a formal act establishing genuineness. It could not make an otherwise unauthorised instrument valid.

Section 3 of the Sales Tax Act entrusted the relevant delegated legislative power to the Federal Government. Neither the Secretary nor the Adviser could exercise it instead.7

Collective responsibility

The Court linked collective decision-making to collective accountability under Article 91(6). Treating one officeholder as the Federal Government would undermine collective parliamentary accountability.

The Court held that the Prime Minister’s position as head of the Cabinet did not permit him to exercise the Cabinet’s authority alone.

Rule 16(2), which enabled the Prime Minister to bypass the Cabinet, was declared beyond lawful authority.8

Analysis

The judgment requires decisions to be made by the authority designated by law. Departmental practice cannot alter a statutory allocation of power.

Its practical test is to identify who holds the power, then establish whether that body actually exercised it.9

The implications extend beyond tax. Paragraph 84 addresses ordinances, government bills, and budgetary or discretionary expenditure.

That breadth creates an operational concern: the Cabinet cannot perform every administrative task.

The distinction is functional. Departments may prepare and execute policy. The Cabinet must decide matters that the law reserves to the Federal Government.10

Practical implications

Counsel should obtain the Cabinet summary, approval and routing documents, in addition to the Gazette notification.

Separate three questions: who processed the proposal, who approved it, and who authenticated the resulting instrument.

Where prior Cabinet approval was required, a signed notification remains vulnerable without evidence of that decision.

A statutory grant to another authority must be express and constitutionally permissible. Simply describing a different body as the Federal Government does not make it so.11

Conclusion

Mustafa Impex requires the Cabinet’s collective decision where the law assigns power to the Federal Government. Neither individual approval nor formal authentication can replace that decision.12
