The Sabah state government has reiterated its unwavering position that implementing the Malaysia Border Control and Protection Agency Act 2024 must not diminish the state's constitutional immigration authority, lawmakers heard in the State Legislative Assembly this week. The stance reflects deepening concerns among Sabah's leadership about potential encroachment on powers specifically granted to the state when Malaysia was formed more than sixty years ago. Datuk Joniston Bangkuai, serving as Assistant Minister to the Chief Minister, delivered this message directly to the legislative body while confirming the government had already communicated its concerns through formal channels to Prime Minister Datuk Seri Anwar Ibrahim.

At the heart of Sabah's resistance lies a fundamental constitutional principle enshrined in Article V of the Malaysia Agreement 1963, the foundational document that brought Sabah into the federation. Rather than dismiss the federal law outright, the state administration acknowledges that the Act falls properly within federal legislative competence. However, Sabah insists this federal authority cannot legitimately override the state's immigration powers, which remain both constitutionally protected and operationally essential for managing entry into the state. The government has emphasised that these powers are non-negotiable, using language that signals this position will not be compromised through negotiation or administrative convenience.

A critical component of Sabah's position centres on retaining control of the Sabah State Immigration Department as the designated authority overseeing all entry points into the state. Currently, this department manages the critical function of determining who enters Sabah and under what conditions. The state government has made clear that operational control must remain with this existing institution rather than transitioning to the newly established federal agency. This is not merely a matter of bureaucratic preference but reflects the principle that decisions affecting the state's sovereignty and security should remain within the state's hands, guided by officials accountable to Sabah's population.

Equally significant to Sabah's position is the preservation of authority over Not-To-Land notices, administrative instruments that prevent certain individuals from entering the state. These notices serve as a crucial enforcement mechanism for maintaining border security and protecting state interests. By insisting that issuance authority remain within the Sabah State Immigration Department, the government seeks to maintain discretionary control over a sensitive tool that directly affects individuals' ability to enter Sabah's territory. Loss of this power would represent a meaningful diminution of the state's capacity to manage its own borders and populations.

Chief Minister Datuk Seri Hajiji Noor had previously announced in May that Sabah would postpone implementation of the Act until the federal government provided explicit guarantees protecting the state's special rights. This decision effectively halted the Act's application in Sabah pending resolution of constitutional concerns. Hajiji reinforced that the very foundation of Malaysia itself was contingent upon granting immigration autonomy to both Sabah and Sarawak, making these powers integral to the federation's original constitutional bargain rather than mere administrative conveniences susceptible to reallocation.

The context for this dispute reflects broader tensions about federalism in Malaysia. When Sabah joined the federation alongside Sarawak in 1963, distinct constitutional arrangements were negotiated to address both states' concerns about preserving their distinct identities and interests. Over subsequent decades, the federal government has occasionally sought to exercise greater influence over areas nominally reserved to the states, prompting periodic assertions of state constitutional rights. Immigration control represents one of the few remaining areas where Sabah possesses meaningful autonomous regulatory authority, making its defence particularly significant to the state administration.

For Malaysian observers, this dispute illustrates the ongoing tension between federal consolidation and state autonomy within the federation's structure. The formation of a dedicated federal border control agency reflects legitimate national security interests and modernisation efforts. However, the creation of such an agency does not automatically extinguish state authority over the same subject matter. Unlike unitary state systems where sovereignty resides exclusively at the centre, Malaysia's federal structure theoretically permits concurrent jurisdiction, though the practical allocation of power and responsibility remains contentious.

The implications extend beyond Sabah to Sarawak, which maintains similar constitutional protections and has traditionally coordinated closely with Sabah on matters affecting both states' interests. Should the federal government successfully subordinate either state's immigration authority to the national agency, it would establish a precedent potentially affecting other constitutional protections granted to the East Malaysian states. Sarawak's government has likely monitored Sabah's position closely, understanding that developments in Kota Kinabalu could foreshadow demands on its own authorities.

For businesses, investors, and individuals requiring movement into and within Sabah, the outcome of this dispute carries practical consequences. Clarity regarding which authority makes final determinations on entry eligibility, processing timelines, and appeal procedures affects economic planning and operational efficiency. Prolonged ambiguity about which agency ultimately controls immigration decisions could frustrate cross-border movement and investment processes. Resolution that explicitly delineates federal and state roles while preserving meaningful state autonomy would provide the certainty necessary for economic activity.

The Malaysian government faces a delicate balancing act. National security and border management unquestionably fall within federal responsibility, justifying the creation of a coordinated national agency. Yet honouring constitutional commitments made to Sabah and Sarawak at independence is equally important to maintaining federal integrity and the political consensus underlying Malaysia's multiethnic federation. Negotiations will likely focus on defining how the federal agency and Sabah's immigration department can cooperate and share responsibilities without creating jurisdictional conflicts or duplicative processes.

Moving forward, the resolution will likely involve detailed memoranda of understanding clarifying which decisions rest with which authority and how information and authority will be shared operationally. Such arrangements could preserve both federal coordination objectives and state autonomy interests. However, given the explicitly non-negotiable language Sabah's leadership has employed, any agreement falling short of substantive protection for state immigration powers risks being politically rejected within Sabah regardless of its technical merits. The state government has invested significant political capital in this position, making retreat difficult without demonstrable gains protecting its constitutional interests.
