A civil court chamber in Ankara reached back to a party congress held nearly three years earlier and declared it void, and the aftershock has now cost Turkey’s largest opposition party its sitting leader and ninety members of parliament in a single week.

The Resignations
Ninety lawmakers, led by former Republican People’s Party (CHP) leader Özgür Özel, formally resigned from Türkiye’s main opposition party on Friday, July 24, 2026, marking the largest split in the party’s recent history. Özel signed the founding documents of a new political party the same day, officially starting the legal registration process. The new party’s name and leadership structure are expected to be announced once registration procedures are complete.
How Özel Got Here
The resignations came days after Özel told his final CHP parliamentary group meeting on Tuesday that he intended to establish a new political party, following a prolonged internal leadership dispute that had consumed the party for roughly two months. Özel had led the CHP since defeating Kemal Kılıçdaroğlu for the chairmanship at the party’s November 2023 congress, going on to steer the party through the 2024 local elections, in which the CHP outperformed the ruling AK Party nationally for the first time in decades.
The Ruling That Started It: Absolute Nullity
The crisis traces to a May 21, 2026 ruling by the 36th Civil Chamber of Ankara’s Regional Court of Appeal, which declared the CHP’s November 2023 congress and a subsequent April 2025 extraordinary congress legally void under the doctrine of absolute nullity, citing allegations of irregularities during the leadership election process. The ruling removed Özel and the party’s other elected organs from office and ordered Kılıçdaroğlu and his prior leadership team reinstated. It also nullified every congress and party decision made after the 2023 convention, including a provincial congress held in Istanbul that October.
Two Competing Claims to Legitimacy
The ruling split opinion sharply along lines of which kind of legitimacy should prevail. Özel and his supporters characterized the decision as a judicial overreach into a matter of internal party democracy, arguing that a leadership chosen by convention delegates should not be reversible by a civil court years later. Ankara’s mayor, Mansur Yavaş, said the ruling’s underlying aim was to divide and weaken the CHP as Türkiye’s largest opposition party. Kılıçdaroğlu and his allies took the opposite position, arguing the court’s decision had to be respected because it restored what they considered the party’s legally recognized leadership, and Kılıçdaroğlu formally accepted the chairmanship again on the day the ruling was issued.
The Police Action and Market Shock
Enforcement of the ruling proved contentious. On May 24, Turkish police entered CHP’s main Ankara offices, deploying tear gas and rubber bullets to remove the ousted Özel-era leadership from the building, according to multiple accounts of the events. The ruling also triggered an immediate reaction in financial markets: Turkish stocks fell roughly 6% and trading was briefly halted the day the decision was announced, while state banks reportedly sold between $6 billion and $8 billion to defend the lira as the country’s risk premium rose from 247 to 257 basis points.
The CHP’s Response to the Split
CHP spokesperson Müslim Sarı said earlier in the week that launching a rival party while still remaining formally inside the CHP would not be ethical, and argued that those preparing to leave had failed to articulate any ideological alternative to the party’s long-standing political line, framing the departure as opportunistic rather than principled.
What the Split Could Mean for 2028
Analysts following the crisis have flagged a longer-term consequence tied to the party’s presidential ambitions: Istanbul Mayor Ekrem İmamoğlu’s nomination as the CHP’s prospective 2028 presidential candidate was made under Özel-era congresses now declared void, meaning it could itself be nullified if the underlying court ruling becomes final. That question carries particular weight given that opinion polling from earlier this year showed İmamoğlu leading President Recep Tayyip Erdoğan by a wide margin in a hypothetical runoff.
Why Analysts Are Watching for a Snap Election
Some analysts have suggested Türkiye’s ongoing opposition crisis could increase the likelihood of a snap election, with Mayor Yavaş warning that a struggling economy makes that scenario more plausible the longer the CHP’s internal fragmentation continues. A divided opposition heading into any early vote would represent a materially different electoral landscape than the united CHP that outperformed the AK Party in 2024.
Law and Legal Implications
The absolute nullity doctrine applied here, mutlak butlan under Turkish civil law, treats certain procedural defects in an organization’s governing decisions as void from inception rather than merely voidable, a legal standard that in principle can unwind years of subsequent decisions made under an affected leadership. The ruling reversed an earlier October 2025 decision by the Ankara 42nd Civil Court, which had dismissed the same underlying case as lacking merit, and the CHP has since appealed to Türkiye’s Court of Cassation, meaning the matter remains subject to further judicial review even as its practical consequences, including Özel’s new party, are already unfolding on the ground.
The nullification’s retroactive reach to the 2023 Istanbul provincial congress and other party decisions also raises unresolved questions about which CHP actions taken between 2023 and the May 2026 ruling might face separate legal challenges to their validity, a category of dispute that could extend well beyond the immediate leadership question.
What Özel’s New Party Still Has to Prove
It remains unclear what name, platform, and leadership structure Özel’s new party will adopt once registration concludes, or how many of the CHP’s remaining lawmakers and provincial organizations will ultimately align with it rather than the Kılıçdaroğlu-led CHP. Whether the Court of Cassation will uphold, modify, or reverse the absolute nullity ruling on appeal has not been decided, leaving the legal status of the underlying 2023 and 2025 congresses formally unsettled. The practical effect on İmamoğlu’s 2028 presidential prospects, given the nullification’s reach into his own nomination process, is not yet resolved either. Forensic Times continues to monitor CHP internal proceedings, the Court of Cassation appeal, and the registration of Özel’s new party.
