An Ankara appeals court engineered a seismic shift in Turkey's political landscape on Thursday, issuing a radical ruling that effectively decapitated the country's main opposition party. By declaring the 2023 leadership congress of the Republican People’s Party (CHP) an "absolute nullity," the 36th Civil Chamber of the Ankara Regional Court of Justice summarily deposed current chairman Özgür Özel. In his place, the bench ordered the temporary reinstatement of his octogenarian predecessor, Kemal Kılıçdaroğlu. The judicial maneuver directly threatens to reverse the opposition’s recent democratic gains and secure President Recep Tayyip Erdoğan’s grip on power ahead of critical upcoming national elections.
To understand the scale of this intervention, one must look past the dry legal architecture of the court's 22-page text. This is not a bureaucratic dispute over party bylaws. It is a highly coordinated exercise in judicial warfare.
The Anatomy of a Judicial Coup
The mechanism used by the Ankara appeals court relies on a retroactive legal erasure. The court overturned a October 2025 lower-court decision that had dismissed internal challenges to the CHP’s November 2023 congress. That earlier ruling found the dispute moot because Özel had already solidified his mandate by winning a subsequent extraordinary congress in September 2025.
The appeals court tore up that logic. By ruling that the initial 2023 vote suffered from "absolute nullity" due to unproven allegations of delegate bribery and vote-buying, the judges wiped out the legal foundation of every party decision made over the last two and a half years.
This includes:
- The election of Özgür Özel and his entire executive board.
- The subsequent policy platforms and extraordinary congresses designed to insulate the party from judicial overreach.
- The candidate selection processes that allowed the CHP to humiliate Erdoğan's Justice and Development Party (AKP) in major municipal contests.
The immediate fallout hit the economy like a hammer. Markets panicked instantly. Trading on the Borsa İstanbul was halted following a sharp 6% drop in the BIST 100 index, while banking shares plummeted by more than 8%. Investors understand what the domestic electorate is beginning to realize: political stability in Turkey is an illusion sustained by the gavel.
The Threat of a Rejuvenated Opposition
The timing of this ruling reveals its true motivation. Under Özel’s 18-month tenure, the CHP transformed from a sclerotic, risk-averse legacy institution into an aggressive electoral machine. The party's historic triumphs across municipal mayoralties shook the ruling party's assumption of permanence.
More threatening to the status quo was the CHP's trajectory for the next presidential election. The party had positioned Istanbul Mayor Ekrem İmamoğlu as its primary challenger to Erdoğan. İmamoğlu, currently held in a maximum-security facility near Istanbul following a controversial corruption and insult trial last year, remained the frontrunner in independent polling.
Özel had openly planned to run İmamoğlu for the presidency even from behind bars. By invalidating the CHP leadership, the court throws the legality of İmamoğlu's primary victory into complete chaos. The ruling systematically dismantles the high-command that possessed the spine to run an imprisoned candidate against an entrenched autocrat.
The Trojan Horse Within
The tragedy of the CHP’s current predicament is that the ammunition was supplied from within its own ranks. Justice Minister Akın Gürlek wasted no time pointing out that the lawsuit originated from disgruntled CHP delegates, most notably former Hatay Mayor Lütfü Savaş. This internal factionalism provided the perfect cover for state intervention.
Kılıçdaroğlu’s behavior in the days leading up to the verdict raises serious questions about his role in this transition. Just 48 hours before the court acted, the former leader released a video on X calling for a "purification" of the party, validating state-media narratives about corruption within the current opposition leadership. When the verdict dropped, Kılıçdaroğlu did not condemn the judicial overreach. Instead, he spoke to the pro-government broadcaster TGRT Haber, mildly remarking that he hoped the decision would be "beneficial to Turkey and the CHP."
For millions of opposition voters who marched through the streets of Ankara and Istanbul on Thursday night, chanting "traitor" outside party offices, the alignment between the palace’s objectives and Kılıçdaroğlu’s compliance felt absolute. Kılıçdaroğlu represents a known entity for the ruling government—a leader who presided over a dozen consecutive electoral defeats and whose return guarantees a return to a passive, predictable opposition.
A Blueprint for Total Control
European Parliament rapporteur Nacho Sánchez Amor accurately diagnosed the situation, calling the verdict a well-prepared plan to eliminate the main opposition party and a blueprint for a fully authoritarian system. The state has realized that it no longer needs to ban political parties outright; it can simply alter their internal management through compliant courts until they cease to be a threat.
The CHP has two weeks to appeal the decision to the Court of Cassation. In the meantime, the party faces an existential dilemma. Accepting the ruling means handing control back to a faction that voters decisively rejected in 2023. Resisting it completely risks pushing the century-old party into legal illegality, disqualifying it from participating in the very elections it is favored to win.
Özel told supporters outside headquarters that he did not promise them a path to power through a rose garden, but rather a refusal to surrender. The coming weeks will test whether that rhetorical defiance can survive a state apparatus that has learned to weaponize the rule of law against democracy itself.
