Thuringia premier Mario Voigt to sue university after doctorate revoked over plagiarism doubts
He says the university's decision raises legal questions and will be challenged in court; the controversy dates back to allegations before the 2024 elections.
Thuringia premier Mario Voigt will sue Chemnitz University after his doctorate was revoked amid plagiarism doubts.
Voigt has announced legal action after the Chemnitz University of Technology withdrew his doctoral degree following a lengthy review of his 2008 dissertation, and the university rejected his appeals against that decision.
Timeline and political fallout
The contested dissertation, published in 2008, was titled "The American presidential campaign: George W. Bush versus John F. Kerry." Initial allegations of plagiarism surfaced shortly before the 2024 state elections, when Voigt and the CDU were still in opposition and he led the party as its top candidate.
After the ballot, Voigt helped form a government made up of the CDU, Bündnis Sahra Wagenknecht (BSW) and the Social Democratic Party (SPD) — a grouping sometimes referred to in local coverage as the "coalition of apricot," a reference to the blend of party colours. Since the plagiarism allegations emerged, Voigt has been under sustained political pressure, particularly from the state branch of Alternative for Germany (AfD) led in Thuringia by Björn Höcke.
In January 2026 the university announced it had revoked Voigt's doctorate after a protracted probe. Voigt said at the time he would contest the decision, including in the courts if necessary; he has now made good on that warning and filed a lawsuit.
"From our perspective, the decision raises serious legal questions, especially regarding the assessment criteria and proportionality," Voigt's lawyer said, adding that they view the case as exceptional because, in their view, the university revoked a degree after an "external and independent expert" determined that the conditions for revocation were not met.
Pressure intensified earlier from the AfD: in early February the AfD parliamentary group in the Thuringian state parliament launched a no-confidence vote against Voigt, nominating Höcke as candidate for premier, but Höcke failed to secure sufficient backing.
In mid-May the AfD group released a report it had funded, prepared by the Austrian communications expert Stefan Weber, known publicly as a "plagiarism hunter." The report aimed to identify further allegedly plagiarised passages in Voigt's dissertation. Separately, Voigt has faced criticism over uncredited use of artificial intelligence in speeches and several authored pieces; in June the Frankfurter Allgemeine Zeitung removed one of his opinion texts from its website.
