Petronas, Sarawak lawsuits pose serious ‘constitutional stress test’, headache for Anwar government

An unprecedented legal showdown between the Sarawak state government and national oil corporation Petronas over hydrocarbon resource ownership could change long-assumed understandings of federal power in Malaysia, say analysts.

KUALA LUMPUR: Two opposing legal suits filed in the Federal Court by national oil corporation Petroliam Nasional Bhd (Petronas) and the Sarawak state government over hydrocarbon resource ownership have cast a long shadow over long-assumed understandings of federal power in Malaysia.

Analysts note that the filings — Petronas’ on Jan 10 and Sarawak’s on Feb 23 — represent not merely a corporate-regulatory dispute but the most serious federal constitutional test since Malaysia’s formation in 1963.

“At this stage, the situation does not amount to a constitutional crisis in the classical sense, but it does constitute a significant constitutional stress test with clear political implications,” said Samirul Ariff Othman of Global Asia Consulting and a lecturer at Universiti Teknologi Petronas.

Jamil Ghani, a doctoral candidate at Singapore’s S Rajaratnam School of International Studies, said the Federal Court’s ruling will have serious implications for Prime Minister Anwar Ibrahim’s government and the country’s economic stability.

“A clear and definitive ruling could resolve longstanding ambiguities over federal-state legal boundaries in oil and gas governance. However, if the court adopts a narrow interpretation or leaves room for further contestation, it may instead formalise competing legal claims and prolong uncertainty,” he told CNA.

Samirul added: “The issues before the court are serious because they would have implications well beyond the oil and gas sector, potentially prompting renewed assertions of state authority and reopening long-assumed understandings of federal power.”

THE DISPUTE

Both parties’ turn to the Federal Court represents the latest twist to a saga that goes back to July 2024, when Petronas and the Sarawak state government began talks over the latter’s claim for greater autonomy over its hydrocarbon reserves.

The core dispute is Sarawak’s challenge to the constitutional foundation of Petronas’ monopoly over the country’s hydrocarbon reserves that is stipulated under the Petroleum Development Act (PDA) enacted in 1974.

The state government, through its wholly owned Petroleum Sarawak Bhd (Petros), is demanding regulatory control over the hydrocarbon reserves within its own territory — both onshore and offshore Borneo island.

Petronas is seeking judicial clarity from the Federal Court regarding the regulatory framework governing its upstream and downstream operations in Sarawak. The national oil corporation also wants the court to determine whether it must comply with state mining laws or if the PDA overrides state legislation.

Its case is scheduled for a hearing on Mar 16.

Sarawak, in a nutshell, wants the Federal Court to determine the validity of three federal laws — the PDA, the Continental Shelf Act (1966), and the Petroleum Mining Act (1966) — that the state government is arguing adversely affect and deprive the state of its rights to its natural resources.

No hearing dates have been set for Sarawak’s legal challenge.

“What Sarawak is asking would declare the PDA invalid, destroy Petronas, and open Malaysia to overlapping territorial claims with countries like the Philippines if the Continental Shelf Act is deemed invalid and does not apply to the state,” noted Azmi Hassan, a fellow at the Nusantara Academy for Strategic Research.

CHALLENGE TO FEDERAL STRUCTURE

The Sarawak-Petronas spat is a serious challenge to Malaysia’s federal structure, which combines a constitutional monarchy with a parliamentary democracy, distributing powers between the federal government and 13 states, along with three federal territories, noted analysts.

The quarrel also carries serious ramifications for the national economy, with an annual gross domestic product (GDP) of roughly US$420 billion.

Losing any regulatory control over Sarawak — where over 60 per cent of Malaysia’s natural gas is located — would be devastating for Petronas, which is already grappling with industry-wide headwinds of weak global oil prices and lower-quality oil fields in more difficult geological locations that are hurting its bottom line.

Sarawak has probable and proven reserves of petroleum representing 60.87 per cent of Malaysia’s total reserves, and the state accounts for 90 per cent of Malaysia’s liquefied natural gas (LNG) exports that make up a large portion of the oil corporation’s earnings.

As the sole custodian of the national hydrocarbon reserves, Petronas plays a central role in the national economy.

For the financial year ending December 2025, Petronas reported total revenue of RM266.1 billion, a 17-per-cent decline from the previous year. Net profit also fell to RM45.4 billion, down 18 per cent from the previous year, the company announced on Feb 27.

In October 2025, the government announced that it expected to receive a dividend payment of RM20 billion from the national oil corporation this year. The payout forecast, down from RM32 billion the government received in 2025, is set to be the lowest amount received since 2017.

All of this sustains the country’s civil service of close to 1.7 million employees and other government programmes, particularly those related to affirmative action policies for the country’s politically dominant ethnic Malays.

WHAT’S AT STAKE FOR PETRONAS, ANWAR

Petronas is more than just the custodian for the nation’s hydrocarbon reserves.

One of its most crucial roles is that of the so-called “central aggregator” of the country’s natural gas sector.

Essentially, Petronas enjoys the sole designation as the single buyer, or aggregator, for all gas produced domestically and imported LNG. It pools these gas supplies and sells them to power producer
