PM Cerar is especially happy with Juncker stressing the importance of the rule of law, the prime minister's office said in a press release.

Slovenia is currently putting a lot of effort into getting Croatia to implement the award of the border arbitration tribunal that determined the course of the border in several areas where the countries could not find a solution.

Juncker presented in his address to the European Parliament in Strasbourg today several ambitious proposals for a more united, stronger and democratic EU.

He talked about a scenario for Europe that is based on three principles: freedom, quality and the rule of law. Court decisions must be respected. "The rule of law is not optional in the EU. It is a must," the EU Commission president said.

The Foreign Ministry also welcomed Juncker's address, labelling it as an introduction to the autumn discussions about the EU's goals in 2018.

"We are happy that the speech clearly shows the ambition for the EU to focus on the fields on which the bloc's credibility is built," the ministry said in a press release.

"This includes above all measures to boost the economy, improve social standards and the safety of citizens and the digital environment, as well as a decisive fight against the climate change and the migration issues."

Like Cerar, the ministry is also satisfied that Juncker underlined that the EU was more than just the common market; that it was built on common values like freedom, equality and the rule of law.

"The respect for court decisions is not optional, it is a must," the ministry reiterated Juncker's words. "And we firmly believe that this must remain the motto of EU institutions and members alike."
