Serbian Prime Minister Ana Brnabic is the only one who knows the answers.
Serbia's prime minister says it's up to Novak to explain a "grey area" over his Covid test result.
The unvaccinated Serbian tennis star says he was granted a medical exemption to enter Australia after testing positive for Covid.
There are questions over public appearances he made.
The Prime Minister of Serbia said that a positive result would be a clear violation of the country's rules.
A judge on Monday restored the visa of Novak Djokovic, who had it revoked on arrival in Melbourne last week. The documents presented at the court showed that the man had tested positive for coronaviruses.
He was pictured at an event in Serbia on December 17th. He was at a photo shoot on December 18.
Ms Brnabic told Guy De Launey that if you are positive you have to be in isolation.
She said that there was some grey area because she did not know when he actually got the results.
The person who has tested positive for a drug must not receive a negative test result during the 14-day self-isolation period.
Ms Brnabic said that she would have to consult with the medical people who are in charge of implementing the regulations if it was found that he had broken Serbia's isolation rules.
Dijana told the BBC that it was up to her son to answer questions about his results.
The Australian visa dispute has made headlines around the world. The tennis star is trying to stay in the country so he can defend his title at the Australian Open.
Australia's immigration minister has the power to re-cancel the visa and deport the unvaccinated player.
Border officials are looking into the possibility that the travel entry form included a false declaration about not having traveled in 14 days. Social media posts show him in Serbia and Spain.
Ms Brnabic said she hoped that the Australian government would allow the Serbian star to stay in Australia to play in the tournament.
She did not agree with the player's stance on vaccination, which she said was the only effective response to the Pandemic.
"What matters to me is that we stand by Novak, but at the same time say that vaccination is important for the country and for me as the prime minister," she said.
