Summary
On May 21, 2026, a regional appeals court in Ankara annulled the 2023 congress of Turkey’s main opposition party, the Republican People’s Party (CHP), citing alleged vote-buying and procedural violations. The ruling removed reformist leader Özgür Özel and the entire executive elected at that congress, reinstating veteran politician Kemal Kılıçdaroğlu and the previous party administration. The legal challenge was brought by CHP members, including former Hatay Mayor Lütfü Savaş, and persisted despite an extraordinary congress in 2025 that re-elected Özel. The court’s intervention is highly unusual, as oversight of party congresses typically falls to the Supreme Election Board, not civil courts. The decision follows a broader crackdown on opposition figures, including the arrest of Istanbul Mayor Ekrem İmamoğlu and the removal of dozens of CHP mayors. The CHP has denounced the ruling as a “judicial coup,” sparking mass protests and deepening political uncertainty as the party prepares to appeal.
Detailed Report
1. Key Figures and Parties
Özgür Özel, a reformist politician, was elected CHP leader in November 2023 and led the party to historic victories in the 2024 local elections. Kemal Kılıçdaroğlu, who led the CHP from 2010 to 2023 and lost the 2023 presidential election to Recep Tayyip Erdoğan, was replaced by Özel but has now been reinstated by court order. Ekrem İmamoğlu, the CHP mayor of Istanbul and a prominent opposition figure, was arrested in March 2025 on corruption charges. President Erdoğan, head of the ruling Justice and Development Party (AKP), has denied political motivations behind these judicial actions. The CHP is Turkey’s main opposition party, center-left and secular-leaning, currently the second-largest in parliament and dominant in local government after 2024.
2. Key Institutions and Terms
· Supreme Election Board (YSK): Turkey’s highest electoral authority, overseeing all elections and internal party votes; its decisions are typically final and not subject to appeal.
· Court of Cassation (Yargıtay): The highest appeals court for civil and criminal cases, reviewing whether law was correctly applied.
· Party Congress: The main gathering of party delegates to elect leaders and set policy; its legitimacy is central to party leadership.
· Absolute Nullity (Mutlak Butlan): A legal concept meaning a decision is void from the outset due to fundamental illegality; declaring the 2023 congress “absolutely null” invalidates all decisions made there, including Özel’s election.
3. The Court Ruling
On May 21, 2026, a civil court in Ankara annulled the CHP’s 38th Ordinary Congress, held in November 2023, on grounds of alleged vote-buying and procedural violations. The court cited “absolute nullity” as its legal basis, removing Özel and the entire executive elected at that congress. The ruling ordered reinstatement of Kılıçdaroğlu and the pre-2023 administration. This intervention is highly unusual, as Turkish law typically assigns oversight of party congresses to the YSK, not civil courts; legal experts have criticized the ruling as judicial overreach. The decision was communicated to the YSK and other authorities for enforcement.
4. Who Brought the Challenge and Why
The legal challenge was filed by CHP members and delegates, most notably former Hatay Mayor Lütfü Savaş, alleging the 2023 congress was tainted by cash payments to delegates and procedural violations. These cases were consolidated in early 2024. Despite the CHP holding an extraordinary congress in September 2025, re-electing Özel in an attempt to render the challenge moot, the court proceeded and issued its May 2026 ruling. CHP officials and many observers have characterized the lawsuits as politically motivated, with the timing and persistence of legal challenges fueling suspicions of external influence.
5. Background Context: Timeline
The ruling follows a series of events:
March 18, 2025: Istanbul University annulled İmamoğlu’s degree, barring him from presidential candidacy.
March 19, 2025: İmamoğlu was arrested on charges including corruption and leading a criminal organization; over 100 others were detained.
March 23, 2025: İmamoğlu was placed in pre-trial detention at Silivri Prison, coinciding with the CHP’s presidential primary.
July 16, 2025: İmamoğlu was convicted of insulting Istanbul’s Chief Public Prosecutor, sentenced to one year and eight months.
November 11, 2025: Prosecutors charged İmamoğlu with 142 offences, seeking a cumulative sentence exceeding 2,000 years.
February 2025: Prosecutors opened an investigation into the CHP’s 2023 congress.
September 2025: An Istanbul court annulled the CHP’s provincial congress, removed the elected chair, and installed a caretaker board.
By mid-2026: At least 23 CHP mayors had been jailed and approximately 25 removed from office.
The government has framed these actions as anti-corruption measures, while the CHP and international observers argue they are selective and politically motivated, noting that similar allegations against AKP officials have not produced comparable actions.
6. Immediate Effects and What Comes Next
All decisions made by the Özel administration since November 2023 are now legally in question. Kılıçdaroğlu has been formally reinstated as the legal leader of the CHP, though the practical implications remain complex. Turkish law requires a new party congress within 40–45 days; failure to comply could result in a court-appointed committee managing the process. The CHP has announced it will appeal to the Court of Cassation. If the appeal fails, the annulment becomes final; if successful, Özel could be reinstated. The party’s ability to function and prepare for elections is severely hampered during this period of legal uncertainty.
7. Statements and Commentary from Opposing Parties and Factions
The court’s decision to annul the CHP’s 2023 congress and remove Özgür Özel as leader was met with strong opposition from the reformist faction. Özel and his supporters denounced the ruling as a politically motivated attack on democratic opposition, asserting that the legal process was designed to undermine the party’s electoral mandate. They argued that subsequent internal party votes had already addressed any procedural concerns, rendering the annulment ineffective in practice. Jailed Istanbul Mayor Ekrem İmamoğlu, a key ally of Özel, also dismissed the ruling as illegitimate and framed the dispute as a broader struggle over the future of democracy in Turkey.
In contrast, Kemal Kılıçdaroğlu and the reinstated leadership welcomed the court’s intervention, urging party members to remain calm and united. Kılıçdaroğlu presented the ruling as an opportunity for reconciliation within the party and emphasized the importance of internal stability over personal ambition. The plaintiffs, led by former Hatay Mayor Lütfü Savaş, maintained that the 2023 congress was fundamentally flawed due to alleged vote-buying and procedural violations, insisting that judicial action was necessary to restore internal party democracy. Government officials from the ruling AKP characterized the court’s decision as a routine exercise of judicial independence, emphasizing that the process was initiated by CHP members themselves and that the government had in the proceedings.
Conclusion
The May 2026 court ruling annulling the CHP’s 2023 congress and removing Özgür Özel as leader marks a critical escalation in Turkey’s ongoing political and judicial crisis. The decision has triggered mass protests, deepened legal uncertainty for the opposition, and drawn condemnation from rights organizations, while international governmental responses remain muted. The outcome of the CHP’s appeal and the government’s handling of ongoing unrest will be pivotal for the future of democratic competition in Turkey.
