The HBK said in a press release on Friday that the alleged initiative was a media fabrication.
"Such behaviour by the media is surprising and worrying to say the least, particularly in view of objective and truthful reporting," said the press release, signed by HBK Secretary General Vjekoslav Huzjak.
The HBK said that the Catholic Church supported efforts aimed at promoting "a new road culture" and called on both the public and lawmakers to demonstrate "their responsibility towards their own country and its people".
