What Happens When a Sarawak Law Contradicts Federal Law?

Full disclosure: I am not a lawyer. But I recently loaded the entire Federal Constitution of Malaysia into a RAG (retrieval-augmented generation) system and asked it a question that had been nagging me for a while — what happens when a state law contradicts a federal law? And in particular, what about Sarawak laws that were enacted before the formation of Malaysia in 1963?

The answers, drawn directly from the constitutional text, turned out to be more nuanced than I expected.

The General Rule: Federal Law Prevails

The starting point is straightforward. Article 75 of the Federal Constitution states:

"If any State law is inconsistent with a federal law, the federal law shall prevail and the State law shall, to the extent of the inconsistency, be void."

This is Malaysia's version of a supremacy clause. When state and federal legislation collide, federal law wins and the conflicting state provision is rendered void — not the entire Act, but specifically the inconsistent part.

Meanwhile, Article 4(1) establishes the Constitution itself as the supreme law of the Federation. Any law inconsistent with the Constitution is void to the extent of that inconsistency.

But What About Laws That Existed Before Malaysia?

This is where it gets interesting — particularly for Sarawak, which had its own legal system as a Crown Colony before joining the Federation on 16 September 1963.

The Malaysia Act 1963 addressed this directly:

• Section 73(1) guarantees that all "present laws" (including laws of the Borneo States passed before Malaysia Day) continue to have effect according to their tenor on and after Malaysia Day.

• Section 73(3) re-classifies these pre-existing laws: if a pre-1963 Sarawak law covers a matter that the State Legislature no longer has the power to legislate on, it is treated as a federal law. Otherwise, it remains a state law.

• Section 73(4) is the critical safeguard — the continuation of pre-existing laws "shall not validate or give effect to any provision which is inconsistent with the Constitution." In other words, pre-existing laws are not grandfathered into immunity from constitutional scrutiny.

The Federal Constitution reinforces this through Article 162, which provides that existing laws continue in force but can be modified by the courts to bring them into accord with the Constitution. Under Article 160, the definition of "State law" expressly includes existing laws on matters within state legislative competence, and "federal law" includes existing laws under Parliament's jurisdiction. This means pre-1963 Sarawak laws are fully subject to Article 75 — they must yield to any inconsistent federal law.

Sarawak's Special Protections

Here is where the story takes a different turn. While federal supremacy applies as a general principle, the Constitution carves out significant protections for Sarawak (and Sabah) that limit federal reach into specific domains.

Native Customary Rights

Sarawak has exclusive legislative authority over native matters. Under the Ninth Schedule, List IIA (Supplement to State List for Sabah and Sarawak), Item 13, native law and custom — covering personal law, marriage, divorce, family law, succession, and native court procedures — falls squarely under state jurisdiction. Article 95B(1)(a) confirms these matters are deemed not to be included in the Federal or Concurrent Lists.

The protection goes further:

• Article 150(6A) provides that even during a declared emergency, Parliament's emergency powers cannot extend to making laws on native law or custom in a Borneo State.
• Article 161A(5) prevents the equality provisions of Article 8 from invalidating State laws that reserve land for natives or give them preferential treatment in land alienation.
• Article 161E(2)(d) requires the concurrence of the Yang di-Pertua Negeri (Governor) of Sarawak for any constitutional amendment affecting the special treatment of natives.

Land

Land is generally a state matter under List II of the Ninth Schedule, but Sarawak enjoys additional autonomy:

• Article 95D completely excludes Sarawak from Parliament's power under Article 76 to pass uniform laws on land tenure, landlord-tenant relations, registration of titles, transfer of land, and compulsory acquisition.
• Article 95E means the Sarawak State Government is not required to follow policies formulated by the National Land Council regarding land utilisation and development.

Immigration

Perhaps the most distinctive safeguard:

• Article 161E(4) elevates any immigration powers conferred on the Sarawak Government by federal law to constitutional status — meaning they can only be amended with the concurrence of the Yang di-Pertua Negeri.
• Article 9(3) permits Parliament to impose restrictions on the free movement of citizens between Sarawak and other states, upholding Sarawak's special position on immigration control.

Constitutional Amendments

Overarching all of these protections, Article 161E(2)(c) mandates that no constitutional amendment affecting the legislative powers of the Sarawak State Legislature — or the executive authority of the State over those matters — can be made without the concurrence of the Yang di-Pertua Negeri.

A Real Example: Petroleum

The tension between federal supremacy and Sarawak's pre-federation laws is not merely academic. One of the most striking cases sits at the intersection of oil, sovereignty, and constitutional law.

Sarawak's Oil Mining Ordinance (1958)

Before Malaysia existed, Sarawak had its own Oil Mining Ordinance — Chapter 85 of the Laws of Sarawak, Revised Edition 1958, enacted on 9 June 1958. This Ordinance gave the Governor in Council (now the Majlis Mesyuarat Kerajaan Negeri, the State Cabinet) the power to grant oil exploration licences, prospecting licences, and oil mining leases over Sarawak's land and Continental Shelf. It was, in every sense, Sarawak's own petroleum regime — governing who could explore, who could extract, and under what terms.

The Ordinance defined "land" broadly to include foreshores, submarine areas beneath Sarawak's territorial waters, and the Continental Shelf. Licences could not be assigned or transferred without the prior written approval of the State Cabinet. Any person mining without lawful authority faced penalties and forfeiture of all machinery and products.

Then Came the Petroleum Development Act 1974

Eleven years after the formation of Malaysia, Parliament passed the Petroleum Development Act 1974 (Act 144). Section 2(1) is sweeping:

"The entire ownership in, and the exclusive rights, powers, liberties and privileges of exploring, exploiting, winning and obtaining petroleum whether onshore or offshore of Malaysia shall be vested in a Corporation..."

That Corporation is PETRONAS. Section 2(3) makes the vesting "irrevocable." The Schedule of the Act contains a template instrument for state governments to sign, granting and conveying to PETRONAS "in perpetuity" all petroleum rights. In return, Section 4 provides that PETRONAS shall make "such cash payment as may be agreed" to the Federal and State governments. The specific terms — including the royalty rate — are set out in the individual vesting deeds signed between PETRONAS and each state government, not in the Act itself.

The Contradiction

On paper, these two laws are in direct conflict:

• The Oil Mining Ordinance 1958 vests petroleum licensing authority in the Sarawak State Government through the Majlis Mesyuarat Kerajaan Negeri and the State Minerals Management Authority.
• The Petroleum Development Act 1974 vests all petroleum ownership and rights in PETRONAS, irrevocably.

Under Article 75, the federal PDA should prevail, and the Oil Mining Ordinance should be void to the extent of the inconsistency.

But the Oil Mining Ordinance Is Still Alive

Here is the remarkable part. The Oil Mining Ordinance was not repealed. It was amended — most recently by Cap. A178/2018, effective 3 August 2018. The 2018 amendments were not cosmetic. They:

• Replaced colonial-era references ("Crown" with "State", "Governor in Council" with "Majlis Mesyuarat Kerajaan Negeri")
• Established the State Minerals Management Authority (under the Minerals Ordinance 2004) as the regulatory body
• Updated the definition of "petroleum" to include natural gas, casinghead petroleum spirit, and bituminous shales
• Added provisions for mining structures on the continental shelf (Section 3A)
• Deleted references to "British subjects" and "Her Majesty's dominions"

The Ordinance still governs oil exploration licences, prospecting licences, and mining leases — with the State Cabinet retaining the power to grant them. The definition of "Government" in the 2018 amendment means "the Government of the State of Sarawak." Not the Federal Government. Not PETRONAS.

What Does This Mean?

A note in the Sarawak State Attorney General's annotated copy of Cap. 85, extracted from the Petroleum Mining Act 1966 (F. Act 58/66, as amended by P.U.(A)467/69), provides a partial answer: Section 13(2) states that the Oil Mining Ordinance of Sarawak "shall continue in force except in relation to the exploration, prospecting or mining for petroleum in off-shore land" — those offshore provisions cease to have effect.

This suggests a territorial carve-up: the federal petroleum regime (PDA 1974 / PETRONAS) governs offshore petroleum, while Sarawak's Oil Mining Ordinance may continue to govern onshore oil mining under state authority. Whether this interpretation holds up in practice is a matter for constitutional lawyers and courts, not for a non-lawyer with a RAG pipeline. But the fact that the Sarawak legislature amended Cap. 85 as recently as 2018 — with no apparent challenge from the Federal Government — suggests that both sides accept some form of this arrangement.

This is also consistent with the constitutional protections discussed above. Land is a state matter under the Ninth Schedule, and Article 95D excludes Sarawak from Parliament's power to make uniform land laws. If onshore petroleum is treated as a land matter, Sarawak's authority over it has constitutional backing that goes beyond the ordinary Article 75 analysis.

The Bottom Line

So, does federal law always trump Sarawak law? As a general rule, yes — Article 75 is unambiguous. Pre-existing laws from before 1963 are not exempt; the Malaysia Act 1963 and Article 162 make that clear.

But the reality is more textured. The Constitution deliberately shields Sarawak's authority over native customary rights, land, and immigration from federal override. These are not mere courtesies — they are constitutionally entrenched provisions that require the Governor's consent to amend. In these domains, Sarawak's legislative autonomy is not just preserved but fortified.

The petroleum case illustrates this perfectly. A pre-federation Ordinance and a federal Act appear to contradict each other — yet both remain in force, apparently governing different slices of the same resource. The Constitution does not always produce clean winners and losers. Sometimes it produces a negotiated coexistence, where the lines between state and federal authority are drawn not just by legal text but by political accommodation and historical context.

I am not qualified to say which interpretation would prevail in court. But I find it fascinating that the question itself exists — that the 1958 Oil Mining Ordinance, a relic of Sarawak's pre-federation legal system, was updated and strengthened sixty years later, while PETRONAS continues to operate under its own irrevocable mandate. The constitutional machinery designed in 1963 is still doing its work, and the tensions it manages are very much alive.
