Taking a Tax Case to the Supreme Court of Pakistan: Leave to Appeal After a High Court Reference
A High Court judgment in a tax reference is challenged by a petition for leave to appeal under Article 185(3) of the Constitution, filed within 60 days of the judgment under the Supreme Court Rules, 1980. Leave is discretionary: the petition has to show a question of law that deserves the Court's attention. Constitutional challenges to a tax provision itself now belong to the Federal Constitutional Court, as the super tax cases showed.
Few tax disputes reach the Supreme Court, and those that do are usually decided at the leave stage. Clients looking for the best advocate of the Supreme Court for tax matters need someone who can put the legal point in a few pages that persuade a bench to grant leave, with the record in order.
Leave to appeal, not an appeal as of right
There is no automatic second appeal in tax cases. After the High Court answers a reference, the aggrieved party files a civil petition for leave to appeal under Article 185(3). If leave is granted, the petition becomes an appeal and is heard on the merits; if it is refused, the High Court's judgment stands. The petition must therefore show, briefly and precisely, why the question of law matters: a conflict between High Courts, a misreading of the statute, or an issue affecting many taxpayers.
The 60-day limit and the record
Under the Supreme Court Rules, 1980, a civil petition for leave to appeal must be filed within 60 days of the judgment. Time spent obtaining certified copies is accounted for under the limitation rules, but it is safer to apply for them immediately. The petition is filed through an Advocate-on-Record and argued by an Advocate of the Supreme Court, with the High Court judgment, the Tribunal's order and the documents the questions depend on.
Where tax cases are heard
Tax, customs and revenue matters are generally fixed before benches at the Supreme Court's Principal Seat in Islamabad rather than at the Karachi Branch Registry, so Karachi clients should expect hearings there. Interim relief against recovery is sought by a separate application in the petition.
The Supreme Court and the Federal Constitutional Court
Since the 27th Amendment, constitutional questions sit with the Federal Constitutional Court. Appeals from High Court judgments in tax references continue to the Supreme Court, but where a taxpayer challenges the validity of a tax law itself, the matter goes to the Federal Constitutional Court. That is how the court decided the super tax challenges in January 2026. Choosing the wrong forum costs time a taxpayer rarely has. Our Supreme Court and constitutional practice page explains the current division.
How we approach a tax petition
We start from the High Court judgment and ask a narrow question: is there a point of law on which the Supreme Court is likely to want to hear the case? If there is, the petition is built around it, with the questions stated at the outset and the record limited to what supports them. If there is not, we say so, because a refused petition only adds cost.

Common questions
How do I appeal a High Court tax judgment to the Supreme Court of Pakistan?
By filing a civil petition for leave to appeal under Article 185(3) of the Constitution. The Supreme Court first decides whether to grant leave; only if leave is granted is the case heard as an appeal on the merits.

Under the Supreme Court Rules, 1980, a civil petition for leave to appeal must be filed within 60 days of the High Court's judgment. Apply for certified copies immediately, as the time taken to obtain them is accounted for under the limitation rules.
Which court hears constitutional challenges to a tax law?
Since the 27th Amendment, the Federal Constitutional Court. It decided the super tax challenges to sections 4B and 4C of the Income Tax Ordinance, 2001 in January 2026. Appeals from High Court judgments in tax references continue to the Supreme Court.
