Bošnjak, who has worked for the high-profile law firm Čeferin, was picked by the 22-member committee in Strasbourg from a list that also contained Supreme Court judge Nina Betetto and criminal law professor at Ghent University Nina Peršak.

The committee, whose session was also attended by Slovenian members Andrej Šircelj of the opposition Democrats (SDS) and Matjaž Hanšek of the opposition United Left (ZL), conducted on Sunday interviews with all three candidates and overwhelmingly chose Bošnjak as the most qualified for the post.

The Parliamentary Assembly is to take a secret vote on the candidate on Tuesday. An absolute majority is needed for appointment in the first vote. In a potential second vote, the candidate with the most votes wins; if needed, a second round will be held on Wednesday.

The new judge will be appointed for a period of nine years without the possibility of a second term. He or she will succeed Boštjan M. Zupančič, who will remain Slovenia's ECHR judge until a new one is appointed, although his term concluded on 31 October 2015.
