"Spain
Genocide denial was illegal in Spain until the Constitutional Court of Spain ruled that the words "deny or" were unconstitutional in its judgement of 7 November 2007.[79] As a result, Holocaust denial is legal in Spain, although justifying the Holocaust or any other genocide is an offence punishable by imprisonment in accordance with the constitution.[80]"
