The battle of wills is far from over as Serbian tennis star Novak Djokovic, known for refusing to get vaccinated against COVID-19, finds himself once again a guest of Melbourne's Park Hotel after the Australian government invoked extraordinary executive power as it seeks to deport him ahead of the Australian Open.
Djokovic was returned to the immigration detention facility on Saturday after the Australian government said the tennis star's opposition to vaccination could cause "civil unrest."
This has set up yet another high-profile court showdown after the government failed in its earlier attempt to remove the unvaccinated 34-year-old from the country. The case will be heard from 9:30 am (10:30 pm GMT Saturday) by the full Federal Court of three justices, a format that leaves little room to appeal any decision.
For now, the Serbian ace is back at a notorious Melbourne immigration detention facility after a few short-lived days of freedom following his first successful court appeal.
A motorcade was spotted moving from his lawyers' offices – where he had been kept under guard for most of Saturday – to the former Park Hotel facility.
For millions around the world, the Serbian star is best known as a gangly all-conquering tennis champion with a ferocious backhand and his anti-vaccine stance.
In court filings, Australia has cast him as a figurehead for anti-vaxxers and a catalyst for potential "civil unrest" who must be removed in the public interest.
Djokovic's presence in Australia "may foster anti-vaccination sentiment," immigration minister Alex Hawke argued, justifying his use of broad executive powers to revoke the ace's visa.
Not only could Djokovic encourage people to flout health rules, Hawke said, but his presence could lead to "civil unrest."
So with just two days before the Australian Open begins, the defending champion is again focused on law courts rather than center court.
After months of speculation about whether Djokovic would get vaccinated to play in Australia, he used a medical exemption to enter the country a week ago, hoping to challenge for a record 21st Grand Slam title at the Open.
Many Australians – who have suffered prolonged lockdowns and border restrictions – believe Djokovic gamed the system to dodge vaccine entry requirements.
Amid public outcry, Prime Minister Scott Morrison's government revoked Djokovic's visa on arrival.
But the government was humiliated when a judge reinstated Djokovic's visa and allowed him to remain in the country.
This time, the government has invoked exceptional – and difficult to challenge – executive powers to declare him a threat to public health and safety.
Experts say the case has taken on a significance beyond the fate of one man who happens to be good at tennis.
"The case is likely to define how tourists, foreign visitors and even Australian citizens view the nation's immigration policies and 'equality before the law' for years to come," said Sanzhuan Guo, a law lecturer at Flinders University.
Djokovic's lawyers argue the government "cited no evidence" to support their claims.
The minister admitted that Djokovic is at "negligible" risk of infecting Australians, but argued his past "disregard" for COVID-19 regulations may pose a risk to public health and encourage people to ignore pandemic rules.
Public records show he attended a stamp unveiling, youth tennis event and granted a media interview around the time he got tested and his latest infection was confirmed.
Djokovic is the Australian Open's top seed and a nine-time winner of the tournament. He had been practicing just hours before Hawke's decision was announced.
The visa cancellation effectively means Djokovic would be barred from obtaining a new Australian visa for three years, except under exceptional circumstances, ruling him out of one of the four Grand Slam tournaments during that time.
He is currently tied with Roger Federer and Rafael Nadal with 20 Grand Slam titles each.
Serbian President Aleksandar Vucic on Friday accused Australia of "mistreating" the country's biggest star and national hero.
"If you wanted to ban Novak Djokovic from winning the 10th trophy in Melbourne why didn't you return him immediately, why didn't you tell him 'it is impossible to obtain a visa'?" Vucic said on Instagram.
"Novak, we stand by you!"
Spanish great Nadal took a swipe at his rival on Saturday as players complained the scandal was overshadowing the opening Grand Slam of the year.
"The Australian Open is much more important than any player," Nadal told reporters at Melbourne Park.
"Australian Open will be a great Australian Open with or without him."
Defending Australian Open champion Naomi Osaka called the Djokovic saga "unfortunate" and "sad" and said it could be the defining moment of his career.
"I think it's an unfortunate situation. He's such a great player and it's kind of sad that some people might remember (him) in this way," she said.
