Calibrating Judicial Review: Doctrinal And Normative Analysis of Pakistan’s Contemporary Challenges to the Twenty-Sixth Constitutional Amendment

The Constitution (Twenty‑Sixth Amendment) Act, 2024, has triggered intense legal and political controversy in Pakistan by restructuring the architecture of judicial power, including appointments, internal court governance, and the scope of Supreme Court and High Court judicial review. Critics argue that the amendment subordinates the judiciary to political control and undermines the constitutional commitment to judicial independence and the rule of law (ICJ, 2024; BIPP, 2024). This article offers a doctrinal and normative analysis of the contemporary challenges to the Twenty‑Sixth Amendment through the lens of three standards of review: Wednesbury unreasonableness, perversity, and proportionality. The research problem is whether Pakistan’s superior courts should evaluate the 26th Amendment using a deferential Wednesbury framework, a limited perversity test, or a rights‑ and structure‑sensitive proportionality standard, given the Court’s existing jurisprudence on salient features in Sindh High Court Bar Association v. Federation (PLD 2009 SC 879) and District Bar Association Rawalpindi v. Federation (PLD 2015 SC 401). Methodologically, the article employs a qualitative doctrinal method, analysing constitutional text (Articles 175, 175A, 184, 199), leading Supreme Court precedents on basic structure and tribalisation, and recent commentary on the 26th Amendment, supplemented by comparative constitutional analysis of proportionality in other common‑law jurisdictions. The article argues normatively that Wednesbury and perversity remain appropriate for ordinary administrative review, but are inadequate for basic‑structure cases. It proposes that proportionality-type scrutiny should govern constitutional challenges to the 26th Amendment, requiring Parliament to justify any impairment of judicial independence and core review functions as necessary and proportionate. The conclusion advances a calibrated model of judicial review: deferential in routine governance, but structured and exacting where amendments threaten the Constitution’s Islamic‑democratic, federal, and rights-protective core.
