Gollnisch was condemned in January 2007 to a three-month prison sentence on probation and ordered to pay costs of 55,000 Euros (with interest) by the Lyon tribunal correctionnel on a charge of "an offence of verbal contestation of the existence of crimes against humanity, " which is punished in France by virtue of the 1990 Gayssot Act.
Gollnisch had committed the verbal contestation on 11 October 2004, by declaring:
I do not question the existence of concentration camps but historians could discuss the number of deaths.
As to the existence of gas chambers, it is up to historians to speak their minds ("de se déterminer").

In reaction to a report denouncing the complacent attitude of the University Lyon III with respect to the far right, Gollnisch reiterated his declarations shortly after its publication.
Gollnisch's declarations, with their implication of holocaust denial, provoked a scandal, especially in the run-up to the ceremonies commemorating the 60th anniversary of the liberation of the Auschwitz extermination camp.
The chancellor of the university asked the Minister of National Education to suspend Professor Gollnisch, and announced the opening of a disciplinary procedure against him.

On 26 December, the chancellor suspended Professor Gollnisch's classes for 30 days.
Furthermore, on 2 December, the chancellor excluded him from the university, alleging a possible breach of the peace; however, this decision was overturned by the Conseil d'État on 14 January 2005.

On 2 February, Gollnisch started teaching again at Lyon III.
Students were prevented from entering his lecture room by groups of students from left-wing and Jewish associations.
A group of National Front students enabled his students to enter and blocked the protesters.
A brawl ensued; police officers arrived on the scene and a National Front student was arrested.
Other trouble ensued.

On 7 November 2006, at the opening of the trial, Gollnisch was asked whether "the organised extermination of European Jews by the Nazi regime (...) constitutes an undeniable crime against humanity, and that it was carried out notably by using gas chambers in extermination camps".
He replied "absolutely".
Gollnisch was finally found not guilty by the Cour de cassation on 24 June 2009.

On 23 October 2012, Gollnisch visited Hungary to deliver a speech in honour of Jobbik, a party described as "anti-Semitic" by the New York Times and as "extremist" by Marine Le Pen.
In the speech, Gollnisch declared that the Treaty of Trianon was "unjust and shameful."
Condemnation of the Treaty of Trianon is seen by Romania as the endorsement of irredentist claims on Romanian territory and of the redrawing of the map of Europe.
