Hojs has responded to the media reports by telling commercial broadcaster POP TV he did not understand why people were getting so upset. "If everything was conducted properly, this will be confirmed, but looking into this is the right thing to do," he said.

TV Slovenija reported unofficially that Hojs wants a revision of the NBI's investigations involving Banka Slovenije in connection to the state of the Slovenian banking system in 2012, into the public procurement of stents, and into the responsibility of public office holders for the situation in paediatric cardiology.

While the minister's order has come under fire from the opposition, several experts have also indicated Hojs has gone too far.

Security expert Miroslav Žaberl told TV Slovenija that "the police force is led by the police commissioner ... and the minister cannot be the one telling him which internal oversight needed to be conducted".

The head of the Association of Criminal Police Officers, Slavko Koroš, told the public broadcaster that the minister can issue certain guidelines and instructions, "however the minister's domain does not cover police procedures whose directing has been taken over, in line with the act governing criminal proceedings, by the state prosecutor".

The two police trade unions issued diverging opinions. The SPS said that political issues should be left to politicians, while the PSS expressed concern.

"If the instructions entail a criminal act that is prosecuted ex officio, the matter will have to handed over to the Specialised State Prosecution," the PSS's Andrej Kocbek announced, albeit saying Hojs's document still needed to be studied.
