A constitutional confrontation is escalating between Punjab and Khyber Pakhtunkhwa provinces over interprovincial trade restrictions that critics say violate Pakistan's Constitution and risk inflaming ethnic tensions between Punjabis and Pashtuns.
Punjab Chief Minister Maryam Nawaz and her provincial government are facing calls for treason charges under Article 6 after allegedly imposing restrictions on goods entering or leaving the province — actions that constitutional lawyers say directly violate Article 151 of Pakistan's Constitution.
Article 151 explicitly states that "A Provincial Assembly or a Provincial Government shall not have power to make any law, or take any executive action, prohibiting or restricting the entry into, or the export from, the Province of goods of any class or description."
The constitutional provision was designed to prevent exactly this scenario: provinces using trade barriers to advance political agendas or discriminate against other regions. Its violation raises fundamental questions about Pakistan's federal structure and the supremacy of constitutional law over provincial politics.
Constitutional experts interviewed for this story emphasized the clarity of Article 151's language and the serious implications of provincial governments disregarding it. "This isn't a gray area," one Lahore-based constitutional lawyer said, speaking on condition of anonymity. "The Constitution explicitly forbids provinces from restricting interprovincial trade. Any such action is unconstitutional, full stop."
The crisis has taken on a dangerous ethnic dimension, with accusations that Punjab's government is deliberately targeting Khyber Pakhtunkhwa — a predominantly Pashtun province — in ways that echo historical grievances about Punjabi political and economic dominance.
Pakistan's federal system has long struggled with tensions between provinces over resource allocation, revenue sharing, and political representation. Punjab, as the country's most populous province, wields disproportionate political influence, while smaller provinces like Khyber Pakhtunkhwa, Balochistan, and Sindh have periodically accused the center and Punjab of marginalizing their interests.
Economists warn that interprovincial trade barriers could have severe economic consequences for a country already struggling with inflation, currency depreciation, and IMF loan conditionalities. Pakistan's economy depends on the free movement of goods between provinces, particularly agricultural products from Punjab and minerals and other resources from Khyber Pakhtunkhwa and Balochistan.
"If provinces start imposing trade restrictions on each other, you're essentially creating internal borders in what's supposed to be a single economic unit," said an Islamabad-based economist who requested anonymity. "This would be catastrophic for economic stability and investment confidence."
The political motivations behind the restrictions remain unclear, but analysts point to ongoing tensions between Punjab's ruling Pakistan Muslim League-Nawaz (PML-N) and Khyber Pakhtunkhwa's Pakistan Tehreek-e-Insaf (PTI) government as a likely factor. The two parties have been locked in bitter conflict since PTI's Imran Khan was removed from power as prime minister in 2022.
Critics of Maryam Nawaz argue that using provincial powers to wage political battles against opposition-governed provinces threatens Pakistan's democratic fabric and constitutional order. Calls for Article 6 treason charges — typically reserved for actions like abrogating the Constitution or overthrowing the government — reflect the severity with which legal experts view the alleged violations.
The federal government in Islamabad has remained conspicuously silent on the dispute, raising questions about whether it will intervene to uphold constitutional provisions or allow provincial conflicts to escalate.
In Afghanistan, as across conflict zones, the story is ultimately about ordinary people navigating extraordinary circumstances. In Pakistan, ordinary traders, farmers, and businesses face the prospect of economic disruption and bureaucratic barriers because of political conflicts between provincial elites — a reminder that constitutional crises often have very concrete human costs.
