Fr. Thomas Rosica, Vatican spokesperson, has threatened to sue David Domet of Vox Cantoris for his allegedly libellous blog posts.

From here:

On February 18th 2015, it was reported on churchmilitant.tv that Fr. Thomas Rosica had issued threat of lawsuit against David Domet, of the Catholic blog “Vox Cantoris”. In the document issued from Folger, Rubinoff LLP, Domet is accused of having made false and defamatory statements about Rosica. David Domet has been critical of the outspoken and progressive positions of Fr. Thomas Rosica on church affairs.

If a lawsuit does come to fruition, it would be an unprecedented action for a Vatican official to bring litigious action against a private citizen and member of the church for expressing a critical opinion of the Vatican hierarchy.

The document from Folger, Rubinoff LLP, demands that nine statements, made by Domet, be retracted from the blog and a public apology to Rosica must be posted. It also notes that compliance with a retraction and apology will not remove the threat of litigation, but will merely reduce alleged damages.

Here is the report that the Wikipedia article references:

While even the threat of being sued is, at best, disagreeable, David Domet should be thankful he is not an Anglican. In my case, Bishop Michael Bird bypassed requests, threats, warnings and cease and desist letters, going, instead, straight for the jugular by suing me for $400,000 over posts I had made about him.

Only in Canada; I don’t think the clergy would get away with this in the U.S.
