Sweden's Parliament approved a constitutional amendment on November 4, explicitly criminalizing Holocaust denial under the country's laws governing freedom of the press and expression. The measure also covers the denial of certain other international crimes and will take effect on January 1, 2027.

The amendment clarifies and expands existing provisions against incitement to hatred against protected groups. Under the revised rules, publicly denying the Holocaust and certain other established international crimes can constitute an offense when the legal requirements are met. The legislation also addresses the justification or gross trivialization of genocide and crimes against humanity.

The changes extend the existing framework to publications and other forms of expression covered by Sweden's constitutional protections for freedom of the press. The amendment also makes clear that incitement to violence falls within the scope of the provisions and gives individuals belonging to protected groups the ability to seek damages as injured parties.

The parliamentary vote on November 4 was the final approval required for the constitutional change. Sweden requires constitutional amendments to pass two parliamentary votes with a general election held between them. The proposal initially passed in May 2024 before receiving final approval from the newly elected Parliament this week.

The amendment follows earlier changes to Sweden's Criminal Code, which took effect in July 2024. Those provisions explicitly criminalized Holocaust denial and the denial of certain other serious international crimes under the country's existing hate-speech framework. The January 2027 implementation date applies to the corresponding constitutional changes involving freedom of the press and expression.

Swedish officials have described the legislation as part of broader efforts to combat antisemitism and protect communities targeted by racist incitement. The government has argued that explicitly addressing Holocaust denial and other international crimes provides greater clarity in the country's existing legal protections.
