With Bangsamoro’s first parliamentary elections now scheduled for September 2026, the region appears to be approaching an important moment in its transition from armed conflict to democratic governance. The Philippine Congress recently approved on final reading a measure setting the election date, a bill now awaiting enactment pending the president’s signature. After years of repeated delays and uncertainty surrounding the electoral timetable in the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM), this legislative momentum offers long-awaited clarity about the transition’s next phase.
However, the establishment of a new electoral timetable does not fully resolve constitutional questions surrounding the transition. A number of petitions filed with the Supreme Court have introduced legal challenges that may affect both the structure of the Bangsamoro transitional government and the legal framework governing the region’s parliamentary elections.
Legal Challenges to the Electoral Framework
In January of this year, the Bangsamoro Transition Authority (BTA) Parliament enacted a new redistricting law intended to comply with a Supreme Court ruling issued the previous year, which invalidated earlier districting arrangements and required elections to be held on or before March 30, 2026. Legal and operational constraints following the passage of the law complicated election preparations, and prompted the Commission on Elections to postpone the polls to a later date within the year.
While the national government has consistently expressed support for holding the Bangsamoro parliamentary elections this year, the new redistricting measure has drawn scrutiny from several quarters. The Moro Islamic Liberation Front (MILF), while not opposed to elections, has raised concerns that the enabling redistricting law reproduces legal vulnerabilities similar to those identified by the Supreme Court when it invalidated the previous districting arrangement for failing to meet criteria under the Bangsamoro Organic Law (BOL). The MILF argues that the electoral framework must be carefully structured to withstand judicial review and remain consistent with the BOL, which established the BARMM and provides the legal framework for its transitional governance and political institutions.
Debates surrounding the redistricting law have also intersected with broader questions about the composition and political balance of the BTA Parliament. Deliberations on the measure appeared to reveal shifting alignments among members of parliament, prompting some figures within the MILF to argue that the transition authority no longer reflects the political configuration originally envisioned under the BOL.
These tensions have also surfaced in the legal arena. One petition filed before the Supreme Court seeks to invalidate several presidential appointments to the BTA, arguing that the appointments altered the political balance of the interim parliament and, therefore, raise questions about the integrity of the transition arrangement. Petitioners contend that these developments affect representation and procedural fairness as the region prepares for its first parliamentary elections. Further legal uncertainty has emerged through another petition filed before the court seeking to nullify several Bangsamoro laws governing the region’s parliamentary elections. Petitioners argue that elements of the districting framework and related electoral provisions conflict with both the BOL and the Philippine Constitution. Together, these cases introduce an additional layer of uncertainty for the region’s first parliamentary polls.
Such concerns are not merely hypothetical. The Supreme Court has previously intervened in Bangsamoro electoral arrangements, including invalidating districting laws last year shortly before scheduled elections. These precedents illustrate how judicial rulings have the potential to impact both the electoral timetable and the institutional foundations of the Bangsamoro transition.
Lingering Trust Deficits in the Bangsamoro Transition
These legal disputes also intersect with broader political tensions between the Philippine government and the MILF. Disagreements over representation and procedural fairness have contributed to lingering mistrust between the two sides. The tensions became more visible during deliberations over the new redistricting law, which exposed emerging factions within the MILF bloc in the BTA Parliament and raised questions among some members about whether the interim transition government still reflects the MILF-led arrangement envisioned in the peace agreement.
Trust between the parties had already been tested by leadership and appointment decisions within the transitional government. The replacement of MILF chair Murad Ebrahim in March 2025 as interim chief minister by Abdulraof Macacua, another MILF leader who commands the group’s armed wing, through presidential appointment marked a sensitive moment in the transition. Controversy emerged over several presidential appointments to the transition parliament, particularly the process that led to the selection of the current interim chief minister, which the MILF leadership described as having been “unilaterally decided” by the national government. For MILF and its allies, such decisions departed from the consultative approach that had typically characterized negotiations under the peace agreement.
These tensions have increasingly surfaced in Bangsamoro public discourse. In October 2025, the MILF publicly expressed its “loss of trust” in national government actors involved in implementing the peace agreement, particularly the head of the Office of the Presidential Adviser on Peace, Reconciliation, and Unity (OPAPRU). This sentiment has been echoed by MILF-affiliated groups and civil society actors in the region, who accuse the office of interfering in BTA appointments and leadership selection without adequate consultation – claims that underscore the fragile relationship between Manila and key stakeholders in the Bangsamoro transition.
As the Bangsamoro approaches its first parliamentary elections, these tensions are likely to shape both political alignments within the MILF and broader perceptions of the transition’s credibility.
Risks of Polarization and Localized Violence
Peace processes rarely unravel all at once. More often, they weaken gradually as strains in relationships persist and intensify without a clear means of resolution.
While political dynamics in Manila naturally fluctuate, developments affecting the leadership of institutions responsible for implementing the peace agreement have also become a point of concern. The recent resignation of the chair of the government peace implementing panel prompted the MILF leadership to call on the national government to appoint a fully empowered panel chair capable of sustaining dialogue between the parties. In its latest response, the OPAPRU maintained that the selection of the panel’s leadership is an internal matter of the government.
Concern over the broader direction of the peace process has also been echoed by civil society actors in the Bangsamoro. In a recent statement, a coalition of multisectoral stakeholders, including former members of the Philippine government negotiating panel, called on President Ferdinand Marcos, Jr. to exercise a “decisive leadership” to “restore confidence in the peace process”. These public interventions reflect growing unease among key stakeholders about the direction and coordination of the transition.
This episode illustrates how shifts within national government institutions in Manila can reverberate through the peace architecture, where continuity in dialogue mechanisms remains critical for managing disagreements between the parties.
In a recent report, the International Crisis Group urged both the Philippine government and the MILF to restore trust, warning that progress on the normalization track, particularly the delivery of social and livelihood packages to decommissioned combatants, should not stall. The MILF’s directive last year for its local fighters to refrain from participating in the government’s decommissioning activities was widely interpreted as a visible indication of strain in its relationship with the national government. In response to these tensions, the MILF has mobilized its constituencies across the Bangsamoro, both to demonstrate the breadth of its public support and to signal that it retains the capacity to maintain cohesion among local commanders despite internal pressures.
Meanwhile, the Interim Chief Minister of the BTA, who faces legal petitions concerning his appointment, has emphasized efforts to maintain unity within the Bangsamoro. During the controversy surrounding the petition, he issued a strong public statement regarding those he believed were behind the legal challenge, expressing concern that the petition had questioned his capacity and commitment to lead the Bangsamoro government.
Altogether, these developments heighten the risk of polarization within communities if political tensions within the MILF leadership begin to resonate among local actors. In contexts where armed groups are undergoing demobilization and political institutions remain in transition, competing narratives about legitimacy and leadership can sharpen divisions among communities and political constituencies. In particular, these dynamics may encourage local actors to align themselves with rival political camps or factions, particularly where loyalties remain closely tied to former command structures. If not carefully managed through sustained dialogue and credible institutional processes, localized disputes or grievances among former combatants could translate into isolated incidents of violence.
Electoral competition may further reshape local political dynamics. Contests for parliamentary seats could encourage local elites and political actors to align with competing factions, potentially polarizing communities in the lead-up to the elections. Should these tensions deepen, the Bangsamoro transition could enter a more fragile political phase, particularly if political rivalries begin to overshadow the fragile gains of the peace process.
Bangsamoro and the Philippines’ Broader Security Environment
Developments in Bangsamoro also intersect with the Philippines’ broader security environment. As Manila faces persistent maritime tensions with China in the waters west of the Philippines, maintaining domestic political stability remains an important strategic consideration. A successful transition in Bangsamoro could consolidate the region’s internal security and allow the Philippine government to focus greater attention on external challenges. Conversely, renewed instability in the region could complicate the country’s broader security priorities. This emphasis on internal stability also aligns with Manila’s broader diplomatic objectives as the Philippines bids for a non-permanent seat on the United Nations Security Council.
The international dimension of the peace process has also come under renewed attention. At the height of negotiations, the International Monitoring Team (IMT) served as an important confidence-building mechanism between the parties, helping monitor ceasefire compliance and sustain stability on the ground. In recent years, however, concerns have emerged that the role of international support mechanisms in the peace process, including the IMT, has gradually diminished during the implementation phase, raising questions about the institutional architecture that has long supported the peace agreement.
At the same time, the Bangsamoro transition unfolds as the Philippines strengthens its security partnerships with external actors. The expansion of the Enhanced Defense Cooperation Agreement (EDCA) with the United States, including the establishment of additional facilities in parts of Mindanao, reflects Manila’s efforts to respond to shifting regional security dynamics. In this broader strategic context, sustaining stability in Mindanao remains important not only for domestic peacebuilding but also for maintaining a security environment in which the Philippines can manage both internal and external challenges.
A Crucial Test for the Bangsamoro Transition
At the onset, the trajectory of the Bangsamoro transition will depend on how key actors navigate this next phase of the peace process. For the national government, rebuilding trust and sustaining the consultative spirit of the peace agreement will remain important in maintaining confidence in the transition’s institutional arrangements, including ensuring clarity and coherence among the institutions responsible for implementing the agreement, such as the government peace implementing panel and the OPAPRU.
For the MILF, the shift toward electoral politics will require managing internal differences while preserving organizational cohesion as the movement evolves from a revolutionary force into a governing political actor. At the same time, local communities and political leaders across the Bangsamoro will play a critical role, as their ability to manage political competition peacefully will determine whether emerging rivalries remain within democratic institutions or escalate into localized tensions.
In addition to serving as a procedural milestone, the 2026 BARMM parliamentary elections will therefore serve as an important test of whether the institutions created by the peace agreement can sustain a durable transition from conflict to democratic governance.
