A Holocaust-denying former bishop from an ultra-traditionalist Catholic splinter group lost a European Human Rights case against a conviction in Germany.

Richard Williamson had been fined €1,800 for denying there were gas chambers in Nazi Germany’s death camps in a 2008 interview with Swedish television carried out in Germany.

The European Court of Human Rights (ECHR) in Strasbourg rejected Williamson’s rights case as “manifestly ill-founded,” describing the sentence imposed on him as “very lenient.” Originally, Williamson had been fined €12,000, but the amount was lowered following an appeal.

Williamson, who is British, argued that the 2013 sentence violated his right to free expression and that Swedish rather than German law should have applied to the interview. Holocaust denial is not illegal in Sweden, but it is a criminal offence in Germany.

But the court said Williamson had clearly known his comments would cause concern, not just in Sweden but worldwide.

When Williamson gave the interview, he was a bishop in the ultra-traditionalist Catholic group the Society of Saint Pius X.

Williamson was excommunicated by the Vatican in 1988 but allowed back into the church in 2009. After carrying out an unauthorised consecration of a bishop in Brazil, he was excommunicated again in 2015.
