    If Djokovic Goes, What Happens to the Australian Open Bracket?

    “Limbo,” the former Australian Open tournament director Paul McNamee had said this week, “is the worst scenario for the tournament.”Yet for days, the uncertainty of Novak Djokovic’s status had hung over the event. The decision on Friday to cancel his visa for the second time could yield some clarity. His plan to appeal that ruling will only extend it.But coming when it did, a day after Djokovic was placed in the No. 1 spot in the men’s draw, the cancellation of his visa — if it is upheld — could force a reshuffling of the men’s bracket.If Djokovic were to be kicked out of Australia, the draw for the men’s singles tournament would have to be reconfigured. According to Grand Slam rules, the No. 5 seed, Andrey Rublev, would move into Djokovic’s vacant slot in the draw. Rublev’s place at No. 5 would then be filled by another seed as part of a series of cascading changes.But if Djokovic appeals and delays his departure, or if his withdrawal were to come after the order of play for opening day has been released, his place would be taken by a so-called lucky loser: a player who had lost in the qualifying tournament and then been drawn by lot to receive a newly open spot.And instead of having Djokovic as the favorite to win his record 10th title, and 21st Grand Slam singles championship over all, the focus would shift to three of his most likely rivals for the trophy: the U.S. Open champion Daniil Medvedev; the Olympic champion Alexander Zverev; and the 20-time Grand Slam champion Rafael Nadal.None of it, of course, is ideal for the Open.“If Novak was going to be kicked out,” McNamee said, “the time to do it was before the draw.” More

    Novak Djokovic has legal options, but they are narrow.

    A second appeal of his canceled visa to enter Australia faces tougher hurdles and less chance of success.Novak Djokovic’s lawyers said on Friday night that they would challenge the Australian immigration minister’s decision to cancel his visa again, but experts said that he would find it much more difficult than his first court challenge.If he doesn’t want to simply comply with the cancellation and leave the country, he will need to apply for a court injunction to stop the Australian authorities from deporting him while his lawyers file a challenge, according to Mary Anne Kenny, an associate professor of law at Murdoch University. That would allow him to stay in the country, but he would most likely be held in immigration detention, where he was kept for five days before his first court challenge.He could, however, apply to the government for a bridging visa to let him stay out of immigration detention and continue to play tennis. But according to Daniel Estrin, an immigration lawyer, Djokovic is unlikely to be granted such a visa because he would have to abide by the condition that he cannot work. His participation in the Australian Open which begins on Monday, then, would disqualify him.But because Hawke’s discretionary powers are so broad, Estrin and Kenny said Djokovic would find it significantly more difficult than his first appeal.The minister just needed to demonstrate that Djokovic might be a risk to the health, safety or good order of the Australian community, Estrin said. That is a very low threshold — “anyone might be a risk to the Australian community if you look at it very broadly” — making it extremely difficult for Djokovic to argue his case on substance, he added. Instead, Djokovic would need to prove that Hawke made an “jurisdictional error,” or applied the law wrong, Estrin said — a much higher legal threshold.Djokovic’s lawyers will not be allowed to replead his case or argue that he should have been allowed into Australia, Estrin said, meaning that, as in his first appeal, he would have to succeed on procedural grounds.“The court doesn’t look at whether the minister made the right decision,” Estrin said. “The court will only look at whether the minister committed some error of law.” More

    With Djokovic’s Status in Limbo, So Is the Australian Open

    Thursday brought no resolution in the star’s duel with the government, even as the tournament’s draw placed him (for now) at the top of the bracket.MELBOURNE, Australia — On the outside courts, spectators were seeking refuge and cool drinks on Thursday as temperatures spiked to over 90 degrees. Players exchanged shots and grunts in qualifying matches, hustling to make the most of their long journeys.But however familiar the sun-drenched scene, this already has been an Australian Open like no other, even though the main event does not begin until Monday.All story lines, all prologue, have been thoroughly overshadowed by Novak Djokovic’s duel with the Australian government over whether he will be allowed to remain in the country and chase a 10th Australian Open singles title.Thursday brought no resolution: only more speculation and the administration of the Australian Open draw, which despite a delay of more than an hour was ultimately conducted smoothly, with Djokovic placed in his now-familiar spot at the top of the bracket.Although Alex Hawke, the Australian immigration minister, has the authority to revoke Djokovic’s visa and order his deportation, Hawke has yet to say whether he will make that bold move. For now, Djokovic is scheduled to face Miomir Kecmanovic, a much younger Serbian compatriot, in the first round and could face Tommy Paul, a rising if unseeded American, in the second round.“I’ve never seen anything like this,” said Brad Stine, Paul’s coach. “It’s obviously not good in so many different ways for the Australian Open or for our sport.”The Australian Open referee Wayne McKewen, center, and the tournament’s director, Craig Tiley, left, at the men’s draw on Thursday.Pool photo by Mark BakerIt was also avoidable. Djokovic is one of only a few top 100 players who have chosen not to be vaccinated against the coronavirus, and his decision to stick to that path, while so many of his peers have made a different choice, helped lay the groundwork for the standoff in Melbourne.Unless there is some significant medical risk that he has yet to make public, Djokovic’s anti-vaccination stance seems a triumph of self-interest over the greater good and has put him and his sport in a tight corner. Unvaccinated, he required a medical exemption to play in the Australian Open, and the state government of Victoria and Tennis Australia, which runs the Australian Open, provided that exemption on the basis of a recent case of Covid-19.The Australian federal government, which controls the nation’s borders, found that insufficient. It canceled Djokovic’s visa upon arrival last week and placed him in detention, only to see that decision overturned by a federal court on procedural grounds on Monday.Liberated, Djokovic has been training at Melbourne Park, where he practiced again on Thursday in the heat. But he has weakened his own case considerably this week, confirming that after testing positive for the coronavirus on Dec. 16, instead of self-isolating, he met with the French journalist Franck Ramella on Dec. 18 in Serbia. Djokovic explained that he did not want to disappoint Ramella, but Ramella wrote in his newspaper, L’Equipe, that Djokovic made no mention of his positive test during their meeting in Belgrade.Djokovic also claimed that his agent incorrectly filled out his Australian arrival documents, inadvertently checking a box that indicated Djokovic had not traveled internationally in the 14 days before his arrival in Australia when he had, it appears, been in Spain and Serbia.Those missteps could be grounds for Hawke to cancel Djokovic’s visa anew, and the Spanish foreign ministry denied published reports that it was investigating whether Djokovic illegally entered Spain despite being unvaccinated.Prime Minister Scott Morrison of Australia, right, had little to say about Djokovic’s case at a news conference on Thursday.Lukas Coch/EPA, via ShutterstockBut for now, Djokovic is in the Australian Open draw, and the men’s tournament is in limbo.“Limbo is the worst scenario for the tournament,” said Paul McNamee, a former Australian Open tournament director.If Djokovic were to be kicked out at this stage, the draw would have to be reconfigured. According to Grand Slam rules, the No. 5 seed, Andrey Rublev, would move into Djokovic’s vacant slot in the draw. But if Djokovic’s withdrawal were to come after the order of play for opening day has been released, he would be replaced by a so-called lucky loser: a player who had lost in the qualifying tournament and then been drawn by lot to receive a newly open spot.In McNamee’s view, “if Novak was going to be kicked out, the time to do it was before the draw.”Grand Slam draws certainly have been revised before. Andy Murray, initially seeded second at the 2017 U.S. Open, withdrew with a hip injury after the draw had been completed.The Novak Djokovic Standoff With AustraliaCard 1 of 4A vaccine exemption question.

    Bob Falkenburg, Tennis Hall of Famer Turned Entrepreneur, Dies at 95

    He won at Wimbledon in 1948 and took some doubles titles before decamping to Brazil and founding a fast-food chain.Bob Falkenburg, the Tennis Hall of Famer who captured the 1948 Wimbledon singles championship in a thrilling fifth-set comeback and also won a pair of Grand Slam men’s doubles titles, then forged a second career as a businessman who introduced fast food outlets to South America, died on Thursday at his home in Santa Ynez, Calif. He was 95.His death was confirmed to The Associated Press by his daughter Claudia.Falkenburg was ranked among the nation’s top 10 tennis players at age 17 and remained in that elite category for the next five years.His signature achievement came at Wimbledon in 1948, when he was down three match points facing John Bromwich of Australia. Relying on powerful backhands and a strong serve, he came back to win his only major singles championship. A year later, Falkenburg won the first two sets facing Bromwich in the Wimbledon quarterfinals, but Bromwich won the last three.Falkenburg teamed with Don McNeill as men’s doubles champions at the U.S. Nationals at Forest Hills in 1944 and with Jack Kramer in the Wimbledon doubles in 1947.The International Tennis Hall of Fame, which inducted Falkenburg in 1974, called him “a thinking man’s player, one who took calculated risks when others might play it safe.”“He was confident that his big booming serve wouldn’t fail him and that his forays to net would lead to winners,” it said.Falkenburg’s brother, Tom, and his sister, Jinx Falkenburg, competed in the U.S. Nationals. But Jinx was best known for her career in show business. She was a model and movie actress, then joined with her husband and manager, Tex McCrary, on the popular radio and early TV breakfast chat program “Tex and Jinx.”Falkenburg entered his last Grand Slam tournament in 1955 after moving to Brazil with his wife, Lourdes Mayrink Veiga Machado, a Brazilian native, whom he married in 1947. He played for Brazil in the 1954 and 1955 Davis Cups.According to the Tennis Hall of Fame, Falkenburg once remembered how on one of his trips from the United States to Brazil he was “distressed that I couldn’t get a decent hamburger or milkshake.”He founded South America’s first fast food and ice cream outlets in 1952 in the Copacabana neighborhood of Rio de Janeiro, calling them Bob’s. His mini-chain consisted of about a dozen outlets when the Falkenburgs, having moved back to Southern California in 1970, sold Bob’s to Nestlé’s Libby operation in 1974. Bob’s has had several ownerships since then and has expanded to more than 1,000 outlets in Brazil and beyond South America as well.Robert Falkenburg was born on Jan. 29, 1926, in Manhattan and grew up in Los Angeles. His father, Eugene, an engineer, and his mother, Marguerite (Crooks) Falkenburg, played in amateur tennis events, and Bob began wielding a racket at private clubs when he was 10 years old.He won a junior tennis tournament to the Bel-Air Country Club in 1937 and, while at Fairfax High School in Los Angeles, won the U.S. Interscholastic singles title in 1942; he also teamed with his brother to win the doubles title that year. He was later a fine amateur golfer and won the Brazilian amateur championship three times.After serving in the Army Air Forces during World War II, Falkenburg won the 1946 intercollegiate singles and double championships while at the University of Southern California.In addition to his wife and daughter, he is survived by his son, Robert, four grandchildren and five great-grandchildren, according to The A.P. Both Tex and Jinx (her birth name was Eugenia; her mother provided her nickname) died in 2003.Describing Falkenburg’s stunning final-set comeback at Wimbledon in 1948, The New York Times reported that “Wimbledon championship fans have seen far better tennis than today’s match, but they’ve rarely witnessed a more exciting one.”As for Falkenburg’s serve that ended the match, 7-5, The Times related how “there was one clear loud pop.”“Bromwich stood flatfooted as the service ace whizzed by him,” The Times wrote. “When a few minutes later, the Duchess of Kent up in the Royal Box presented the coveted trophy to Falkenburg, he looked as surprised as he was pleased.” More

    Novak Djokovic’s Fight to Play Tennis Unvaccinated Could Be Just Starting

    The days-long battle to enter Australia to defend his Open title presages headwinds he may face if he attempts to travel the world without being vaccinated for Covid-19.Novak Djokovic has fought through adversity of his own and others’ making for as long as he has been playing tennis.He beat extraordinary odds to become a champion, emerging from the former Yugoslavia despite economic hardship and a conflict that turned Serbia, his homeland, into an international pariah and made it difficult for him to travel and train. Once on tour, he had to contend with Roger Federer and Rafael Nadal, well on their way to becoming two of the game’s greatest players. Djokovic caught up to them and now holds a career edge in both rivalries. He has also been ranked No. 1 for 356 weeks, a record.Djokovic, stubborn and resilient, has had tougher fights in his career than the one he has faced this month with the Australian government over his visa. But this battle, which continues, is unlike any other he has encountered. It could do him lasting damage despite his surprise victory in Australia on Monday, when a federal court overturned the revocation of his visa on procedural grounds. The ruling still does not guarantee he will not be deported by Australian immigration authorities ahead of the Australian Open, which begins next Monday.Djokovic’s five-day detention, ended by the court ruling, was a blink of the eye compared with the detentions of some longstanding asylum seekers with whom he shared his Melbourne hotel. Djokovic, unlike some of his fellow lodgers, was also free to leave the country at any time. But the experience had to be draining, and it came after a phenomenal but emotionally taxing season in which he came within one match of achieving a Grand Slam before losing the U.S. Open final to Daniil Medvedev. He was also beaten at the Olympics and the ATP Finals by Alexander Zverev.Serbian tennis fans and antivaccination protesters rallied outside the Park Hotel in Melbourne, Australia, in support of Djokovic. Diego Fedele/Getty ImagesBased on transcripts provided to the federal court, he landed in Melbourne near midnight on Wednesday with the seeming belief that all his papers were in order, including his medical exemption from vaccination. He soon learned otherwise.While it is highly unlikely that Djokovic, an outspoken skeptic of vaccines, will find himself sequestered again in any other country over visa issues, the trouble in Melbourne presages some of the headwinds he could face in the months ahead if he continues to attempt to travel the world without being vaccinated for Covid-19.Governments are running out of forbearance in instituting or debating vaccine mandates, and some tennis officials are running out of patience, too. And the pace and direction of the coronavirus pandemic and its variants are unknown.The next major events on tour after the Australian Open are the Masters 1000 events in Indian Wells, Calif., and Miami, which both start in March. But the United States now requires that visitors be fully vaccinated to travel to the country by plane unless they are U.S. citizens, lawful permanent residents or traveling on a U.S. immigrant visa. Only limited exceptions apply, and it is unclear whether Djokovic would qualify for one or would even want to try to qualify for one after the Australian imbroglio.The French Open, which is the next Grand Slam tournament of the season after the Australian Open, begins in May and appears less problematic. The French sports minister, Roxana Maracineanu, told French national radio last week that she expected Djokovic would be allowed to enter the country and compete if unvaccinated because of the health protocols that are planned for major international sporting events in France.Djokovic’s family held a news conference on Monday in Belgrade, Serbia, after Djokovic was to be released from an immigration detention center in Melbourne after a court order.Srdjan Stevanovic/Getty ImagesBut in the same interview, Maracineanu emphasized that any athlete, French or foreign, who was a resident in France would be required to show proof of vaccination to have access to sports training facilities. That is a sign of which way the mistral is blowing. Some professional leagues have left loopholes in place, but gaps are also closing for the unvaccinated.Djokovic, who has long held nontraditional views on science and taken unorthodox approaches to his health, finds himself in the distinct minority with more than 90 percent of the top 100 players on the ATP Tour now vaccinated. If the ATP has made no official statements of public support for Djokovic during his detention, that might not be because Djokovic is now leading a new player group that has been critical of the ATP but because the ATP has pushed increasingly hard for its members to be vaccinated.In 2022, the tour will not require vaccinated players to take more than an initial test once they arrive at a tournament unless they develop symptoms. Unvaccinated players and team members will have to be tested regularly, and the tour will no longer cover the cost of follow-up testing for the unvaccinated.That will pose no hardship to Djokovic, who has earned about $154 million in career prize money and hundreds of millions more off court. But the tour rules do emphasize that Djokovic and the few remaining unvaccinated players are outliers.The Australian authorities have hardly wrapped themselves in glory during L’Affaire Djokovic. There were mixed signals, conflicting memos and other miscommunication between state and federal officials and Tennis Australia, which runs the Australian Open.If there had been a united, coherent effort that sent a clear message about the grounds for medical exemptions from vaccination, Djokovic’s overnight interrogation and visa cancellation could have been avoided.Djokovic after winning the Australian Open last year.Alana Holmberg for The New York TimesHe most likely would not have risked going to Australia if he had understood that the federal government did not consider a recent case of Covid-19 to be grounds for an exemption. But while Djokovic won in court on Monday, he has undoubtedly lost support in some chambers of the court of public opinion, though he has become a martyr for the anti-vaccine movement and among his countrymen.The Novak Djokovic Standoff with AustraliaCard 1 of 4A vaccine exemption question.

    Australia Court Hears Novak Djokovic's Appeal

    His lawyer argued that the tennis star had met all government requirements before flying to the country to compete in the Australian Open.SYDNEY, Australia — A lawyer for Novak Djokovic, the Serbian tennis star, argued in an Australian court on Monday that the government had erred in canceling a visa for Djokovic because he had complied with all the government’s requirements even though he has not been vaccinated for Covid-19.The hearing came five days after Djokovic was detained at an airport after arriving on a flight from Dubai to compete at the Australian Open.Djokovic landed late Wednesday with a visa and a vaccination exemption to play in the tournament, which begins Jan. 17, but border officials canceled the visa with the support of Prime Minister Scott Morrison. The authorities said that Djokovic did not qualify for an exemption from the requirement that everyone entering the country be fully vaccinated.The drawn-out conflict over the world’s top men’s tennis player, who is seeking to win a record-breaking 21st Grand Slam title, landed at the start of an election year in Australia and kicked off another round of international debate over vaccine politics.With the Omicron variant pushing Covid case numbers to new heights both in Australia and the rest of the world, Djokovic’s detention pits those who argue that vaccination is more important than ever for preventing serious illness against those who insist that no one should be forced into inoculation.On multiple occasions, Djokovic has stated his opposition to vaccine mandates, saying that vaccination is a private and personal decision. He had not, however, revealed until last week whether he had been vaccinated.In a court filing on Saturday, Djokovic’s lawyers said that the tennis star tested positive for the coronavirus in mid-December, and that the Australian government had erred in canceling his visa over the vaccine requirement.The Novak Djokovic Standoff with AustraliaWhat Happened: The No. 1-ranked men’s tennis player was refused entry to Australia over questions about a Covid vaccine exemption.Understand the Standoff: Mr. Djokovic, a vaccine skeptic, was granted an exemption that would allow him to defend his Australian Open title. Then the federal government stepped in.A Difficult Moment in Australia: Barring the tennis star offers a chance to change the subject as an election looms and cases are at record highs.Exemption Skepticism: Here’s how the tennis world initially reacted to the news that Djokovic was granted an exemption.On Monday, Anthony Kelly, the federal court judge overseeing Djokovic’s appeal, noted during the hearing that his visa application had included a medical exemption from a physician, supported by an independent panel convened by the Victoria state government.“The point I’m somewhat agitated about is, what more could this man have done?” Judge Kelly said.But the federal government’s lawyers, in their filing, said that past Covid-19 infections were not a valid reason to defer immunization against the virus.Under vaccine guidelines issued in December by the country’s chief medical body, people are expected to be vaccinated against Covid-19 after recovering from “acute major medical illness,” and, the government argued, “the evidence is that the applicant has recovered.”It is not clear if or when Djokovic was ill. On Dec. 16, the day he said he tested positive, he appeared at a live-streamed public event. The following day, he appeared at an awards ceremony for junior players, where photographs showed that he was not wearing a mask.What is clear, even to many Australians who say that the rules should be applied to everyone, including sports superstars, is that they are embarrassed by the whole affair. Australia’s entry process for the tournament, and international travel generally during the pandemic, has been marred by confusion, dysfunction and political point-scoring that all add up to an image of incompetence.Djokovic inadvertently joined the fray on Tuesday, when he announced on Twitter that he had received a medical exemption from the requirement that all people entering Australia be vaccinated or quarantine for 14 days upon arrival.In a statement later that day, Craig Tiley, the chief executive of Tennis Australia, explained that players seeking an exemption had to pass muster with two panels of medical experts. The process included the redaction of personal information to ensure privacy.Communications between national health officials and Tennis Australia, and between Tennis Australia and players, have revealed contradictory messages about whether unvaccinated people infected with the coronavirus during the past six months would receive an automatic medical exemption.Federal officials wrote to Tiley in November to indicate that testing positive for the virus during the past six months would not be sufficient to gain automatic entry into the country without vaccination. But letters leaked to Australian news outlets showed that an adviser to Australia’s federal chief health officer had also told Tennis Australia that the state of Victoria, where the tournament is being held, was responsible for assessing exemptions.On Dec. 2, Brett Sutton, the chief health officer in Victoria, wrote to Tennis Australia: “Anyone with a history of recent Covid-19 infection (defined as within 6 months) and who can provide appropriate evidence of this medical history, is exempt from quarantine obligations upon arrival in Victoria from overseas.”Five days later, Tennis Australia passed on the message to players.Djokovic landed at Tullamarine Airport in Melbourne around 11:30 p.m. on Wednesday. After a nearly 10-hour standoff at the airport, border officials said he would have to leave the country. He was held in a room overnight over the validity of his visa and questions about the evidence supporting his medical exemption.His team filed a legal challenge to the ruling on Thursday. A judge said Djokovic would be allowed to remain in Australia at a hotel that houses refugees at least until Monday as his lawyers awaited a hearing.By that point, the decision had already become political. Australian leaders have a long history of winning elections with tough talk on border enforcement, despite the country’s harsh treatment of asylum seekers in offshore detention centers, and Mr. Morrison has followed a predictable script.Facing a tough re-election campaign as the economy starts to seize up from a surge of absences caused by an Omicron outbreak and a shortage of testing capacity, he pounced on the decision to cancel Djokovic’s visa, trying to frame it as a clear-cut case of law and order.“Rules are rules,” he said, adding, “Our government has strong form when it comes to securing our borders, and I don’t think anybody doubts that.”Critics of Australia’s immigration policies said they were dismayed, but not surprised. The hotel where Djokovic is staying holds dozens of refugees, including some who have been detained for nearly a decade.“As a country, we have been shown over time to be very aggressive in enforcing immigration policy,” said Steven Hamilton, a former Australian Treasury official who teaches economics at George Washington University. “People overseas should view this through that prism rather than as a health measure. It has nothing to do with health.”On Friday, border officials told the Czech doubles player Renata Voracova that she, too, would have to leave the country, even though she had played matches in tuneup tournaments last week.Voracova, who was given a medical exemption because she has had Covid-19 during the past six months, was moved to the same hotel as Djokovic, but opted to leave the country voluntarily rather than fight the deportation ruling.

    Djokovic Tested Positive for Coronavirus in December, His Lawyers Say

    Lawyers for the tennis star, who is appealing Australia’s decision to deny him entry, said the positive test came weeks before he flew to the country.MELBOURNE, Australia — In a court filing on Saturday, lawyers for Novak Djokovic said the tennis star had tested positive for the coronavirus in mid-December, and that the Australian government had erred this week in canceling his visa over a vaccine requirement.Mr. Djokovic, who hopes to defend his men’s singles title at the Australian Open this month, was denied permission to enter the country on Thursday after arriving at a Melbourne airport. The border authorities said they canceled his visa because he had not provided evidence to justify being exempted from Australia’s requirement that arrivals be vaccinated against the coronavirus.In the filing on Saturday, Mr. Djokovic’s lawyers said he had been granted a vaccine exemption by Tennis Australia because of a positive Dec. 16 coronavirus test result, and because 14 days later, he had not had a fever or respiratory symptoms in 72 hours.The conditions of the exemption were consistent with the recommendations of Australia’s immunization advisory body, the lawyers argued. Given these circumstances, among others, “Mr. Djokovic understood that he was entitled to enter Australia,” the filing read.Mr. Djokovic, a vaccine skeptic, is in quarantine at a hotel in Melbourne as he awaits a hearing, scheduled for Monday, on his appeal of the government’s decision to revoke his visa.The Novak Djokovic Standoff with AustraliaWhat Happened: The No. 1-ranked men’s tennis player was refused entry to Australia over questions about a Covid vaccine exemption.Understand the Standoff: Mr. Djokovic, a vaccine skeptic, was granted an exemption that would allow him to defend his Australian Open title. Then the federal government stepped in.A Difficult Moment in Australia: Barring the tennis star offers a chance to change the subject as an election looms and cases are at record highs.Exemption Skepticism: Here’s how the tennis world initially reacted to the news that Djokovic was granted an exemption.He announced in June 2020 that he and his wife had tested positive for the coronavirus, but his December infection had not previously been disclosed.Mr. Djokovic’s lawyers argue that the Australian authorities, in canceling his visa, “radically and fundamentally” misconstrued or misapplied advice from Australia’s immunization advisory body about whether a coronavirus infection within the past six months should exempt him from the vaccination requirement.The filing also claims that Mr. Djokovic was denied procedural fairness after arriving in Australia, when he was held at the airport by the immigration authorities from about midnight to 8 a.m.His lawyers say Mr. Djokovic was initially told by immigration officials that a decision about his visa would not be made until after 8:30 a.m., after he had a chance to speak to Tennis Australia officials. But around 6 a.m., they say, he was pressured to consent to an immediate decision. He relented, “feeling he had no choice,” and was notified at 7:42 a.m. that his visa had been canceled, according to the filing.The Australian Border Force declined to comment on the filing, citing the pending court hearing. Prime Minister Scott Morrison has said that the revocation of Mr. Djokovic’s visa was “simply a matter of following the rules.”If Mr. Djokovic’s appeal fails, he could be barred from entering Australia for three years, under rules applicable to people whose visas are canceled.Separately, the Australian Border Force on Saturday night said that two others linked to the tennis tournament whom it had been investigating had left the country.“The Australian Border Force (ABF) investigation into the visa status of two other individuals connected to the Australian Open has concluded,” it said in an emailed statement. “The ABF can confirm both individuals have now voluntarily departed Australia.”The statement did not identify the two individuals, but local news media had reported the investigations a few days earlier.On Friday, the Czech foreign ministry confirmed in a statement that a Czech player, Renata Voracova, had been placed in the same detention as Mr. Djokovic, along “with several other tennis players.” She had “proven noninfectious status in a way that entitles her to participate in the tournament,” and had already played at a warm-up event, the statement said, but had “decided to give up further participation in the tournament and leave Australia due to the limited possibility of training.”The Australia Broadcasting Corporation also reported that a European tennis official under similar circumstances had left the country.
