(CNN) A federal judge in Florida struck down on Monday the Biden administration’s mask mandate for airplanes and other public transport methods, and a Biden administration official says the order is no longer in effect while the ruling is reviewed.
In the immediate wake of Mizelle’s ruling, Psaki told reporters that the White House wasn’t trying to “provoke uncertainty with passengers” by not providing an immediate response, but added that the administration continues to recommend that airline passengers continue to wear masks.
“So, we would say to anyone sitting out there — we recommend you wear masks on the airplane and … as soon as we can provide an update from here, hopefully soon, we’ll provide that to all of you,” she said.
Following the ruling, several US airlines — Delta, United and Southwest among them — said masks are now optional on their aircraft. In a statement, Alaska Airlines said that passengers whose behavior was “particularly egregious” over the past two years in objecting to the mandate will remain banned from flying on the airline, “even after the mask policy is rescinded.”
Amtrak and the Washington Metropolitan Area Transit Authority, which operates DC’s Metro, also announced that they will no longer require masks for passengers and employees, though the state-owned and operated NJ Transit and the New York Metropolitan Transportation Authority will keep their requirements.
The first part of the judge’s 59-page ruling turned on the meaning of the word “sanitation,” as it functions in the 1944 statute that gives the federal government the authority — in its efforts to combat communicable diseases — to issue regulations concerning “sanitation.”
Mizelle concluded that that the use of the word in the statute was limited to “measures that clean something.”
Other lawsuits that have been filed targeting the mandate — and the directive to enforce it by the Homeland Security Department’s Transportation Security Administration — have failed to succeed in blocking it.
According to a Justice Department filing submitted last week in a separate lawsuit against mandate the brought in Texas, “many other individuals have sought time-sensitive injunctive relief from the CDC or TSA orders that require masks during commercial air travel.”
“The Supreme Court has thrice rejected that relief, and so has every Court of Appeals to consider the issue — that is, the Fourth, Eighth, Eleventh, and D.C. Circuits — as well as the U.S. District Court for the Middle District of Florida,” the Justice Department said in that case, referring to an earlier lawsuit brought in Florida’s Middle District. “No court has granted such relief, and not a single Judge or Justice has noted their dissent from any of these orders.”
Unlike those other cases where judges were weighing emergency or preliminary orders, Mizelle was considering the legality of the mandate on the merits.
In the wake of the ruling, the Association of Flight Attendants urged “calm and consistency in the airports and on planes.”
“We urge focus on clear communication so that Flight Attendants and other frontline workers are not subject to more violence created by uncertainty and confusion,” the union, which represents nearly 50,000 flight attendants, said in a statement.
Republicans cheered the ruling, with Florida Gov. Ron DeSantis posting on Twitter that it was “Great to see a federal judge in Florida follow the law and reject the Biden transportation mask mandate.”
Sen. Chuck Grassley, a top Republican on the Judiciary Committee, said on Twitter that the ruling showed why his work on Trump judicial nominations was “so important to protect [individual] liberty” and “restraining [government] overreach.”
Democratic Sen. Ed Markey, meanwhile, tweeted that a “Trump-appointed judge is obstructing our pandemic response and putting the most vulnerable at risk.”

Supreme Court of Canada
The Supreme Court’s fourth annual review, disseminated on social media and posted on the court’s website, is part of Chief Justice Richard Wagner’s ongoing efforts, after he assumed the court’s leadership in December 2017, to make the court’s work more understandable and accessible to Canadians.
A well-received move in 2021 was the court’s pioneering decision to provide journalists, who sign strict confidentiality and embargo undertakings, with remote online access to selected particularly important or complex decisions for an hour and a half before the judgments are publicly released. The aim is to enable journalists to report quickly and accurately, once the judgment embargo is lifted, without having to be physically locked up beforehand in the close quarters of the media room of the Ottawa courthouse (the Supreme Court’s building was closed to “visitors” in 2021 due to the COVID-19 pandemic.)
The Supreme Court rolled out the first prejudgment remote lockup for journalists on March 25, 2021, the day the high court upheld the constitutionality of the Greenhouse Gas Pollution Pricing Act.
Ten days earlier, Chief Justice Wagner for the first time hoisted a newly created flag up the eastern flagpole in front of the Supreme Court’s imposing art deco building. The court’s new red, white and gold heraldic emblem features a royal Crown — signifying that Canada is a constitutional monarchy — along with nine maple leaves surrounded by a laurel, and undergirded by the court’s longtime motto “Justice and Truth” (in Latin).
The flag goes up each time the court is in session to hear an appeal (previously the court raised the Canadian flag). “These new emblems express the values of our institution: justice, independence, integrity, transparency and bilingualism,” Chief Justice Wagner told the public.
The Supreme Court’s Year in Review provides a brief description of “notable decisions” that year as well as a statistical profile of its work in 2021.
The numbers disclosed by the court reveal that 55 per cent of the cases heard by the court in 2021 involved criminal law (most were as-of-right appeals); 24 per cent were “public” law (including constitutional cases, and administrative law appeals involving, for example, tax, human rights or labour relations); and 21 per cent were cases involving disputes between individuals (for example in the areas of negligence, family law and contracts).
Of the 59 decisions rendered in 2021, 39 per cent were in criminal cases, 34 per cent were in public law cases and 27 per cent were in private law cases.
Close to half of the court’s hearings in 2021 were devoted to as-of-right cases. Of the 58 appeals heard in 2021, 26 were by-right appeals and 32 were by leave.
The nine judges’ decisions revealed more disagreement than agreement — with just 46 per cent of judgments featuring unanimous agreement on the results (down from the 49-per-cent unanimity rate the year before.)
Because of hearing delays due to the COVID-19 pandemic in 2021, the average time-lapse between the court granting leave and argument on an appeal was 8.2 months — down from 8.6 months in 2020 (the first year of the pandemic), but up considerably from 6.3 months the year before.
At the same time, the court was speedy in deciding leave applications in 2021 — taking an average of 2.8 months, the fastest time in a decade. As occurred in 2020, the court received fewer leave applications in 2021, reflecting pandemic slowdowns in the lower courts: 473 leave applications, down from the average of 538 in the eight years preceding the pandemic.
In 2021, the court also took, on average, only about four months to render its decisions — its second-fastest turnaround in 10 years (however, this average turnaround time includes decisions rendered immediately from the bench, which made up a substantial portion of the court’s total output.)
The Supreme Court heard appeals on 58 days in 2021, up from 35 days in 2020.
Overall, the entire Supreme Court appeal process, starting from the date of filing a leave application through to judgment, took 15.2 months, on average, reduced more than two months from 17.4 months in 2020.
The 2021 Year in Review indicates that the Supreme Court decided 59 cases, of which 22 were bench judgments, and 37 were reserved decisions.
