The Novel Coronavirus.

Like everyone else, I was thrilled by Pfizer and BioNTech’s joint announcement of a COVID-19 vaccine that is 90% effective. That made me wonder what exactly is involved in developing and—most importantly—proving that a vaccine works and is reasonably safe. The Pfizer/BioNTech vaccine is in Phase III trials. What does that mean?

The Food and Drug Administration’s process for new drugs normally is complex and lengthy. It can easily stretch out for years and create reams of data. But the FDA can shorten that time when the need is especially great, which certainly is the case with COVID-19 vaccines.

There are several stages to vaccine development which involve exploratory research, multiple rounds of pre-clinical and clinical review, tracking side effects, manufacturing, and quality control. Clinical development has three phases:

Phase I: Small groups take the vaccine to test for safety, efficacy, and to determine the correct dosage.

Phase II: Hundreds of people with different characteristics (such as age and health status) take the vaccine to further understand how it works and whether it is safe.

Phase III: Thousands of people are given the vaccine.

All three phases are tightly controlled and monitored. The FDA reviews the results and may require additional testing or tracking of participants before it approves the vaccine for widespread use. Under various fast-track rules and other programs, the FDA can—and has—changed some of the three phase requirements, including how many people must participate and how long the trials last.

Pfizer and BioNTech will ask the FDA for emergency authorization later this month with just two months of data. The FDA has the authority to allow unapproved medical products to be used in an emergency when there are no adequate or approved alternatives.

As a citizen, I want an effective vaccine as quickly as possible. As a lawyer, I wonder what litigation will inevitably follow with claims that approvals were rushed or wrong. What if vaccines are made mandatory, as the New York Bar Association recommended just last week? Should drug manufacturers receive protections from suit to encourage COVID-19 vaccine development? Like everything this year, so much remains unknown.

President Donald Trump and Supreme Court nominee Amy Coney Barrett at the White House. Photo courtesy of the White House.

Much of this week’s news cycle has been dominated by Supreme Court news including Judge Amy Coney Barrett’s confirmation hearing and possible attempts to expand the Supreme Court beyond the current nine members. I also came across an interesting article in Bloomberg BusinessWeek discussing Congress’s ability to strip the Supreme Court of its powers in order block judicial review of legislation.

I was taught that one of—if not the—bedrock of our democratic system is three equal branches of government asserting checks and balances on each other, so the Bloomberg story surprised me. How can Congress strip a co-equal branch of government of its powers? If that is the case, are they co-equal? Does that put the lie to what I learned in school?

The argument is based on Article III of the Constitution which states:

“The Supreme Court shall have appellate Jurisdiction, both as to Law and Fact, with such Exceptions, and under such Regulations as the Congress shall make.”

This “exception” clause has been accepted as giving Congress the power to remove appellate review from the Supreme Court. But Congress can never remove the Court’s original jurisdiction over disputes between states, actions involving various public officials, disputes between the United States and a state, and proceedings by a state against the citizens or aliens of another state. The sanctity of original jurisdiction was enshrined in the famous Marbury v. Madison decision in 1803.

Jurisdiction stripping is not a new idea. Congress stripped the Supreme Court of the power to hear specific cases as early as 1869 in Ex parte McCardle, 74 U.S. 506 and continues to do so.

The McCardle case is surprising to me. During Reconstruction, newspaper publisher William McCardle printed articles opposing federal Reconstruction laws. After being jailed by the military, he requested habeas corpus review in the Southern District of Mississippi. The District Judge sent him back to jail. He appealed to the Supreme Court. After oral arguments, but before a decision was issued, Congress suspended the Court’s jurisdiction over the case under Article III. Chief Justice Chase, writing for a unanimous court, upheld Congress’s withdrawal of the Court’s jurisdiction. While I am not an expert on this complex area of the law, I am sure Mr. McCardle was shocked that Congress could block court review of his jail sentence. How is a citizen to be protected from Congressional retaliation?

So, jurisdiction stripping is real. A recent example is the Military Commissions Act of 2006 which attempted to strip federal courts of jurisdiction over appeals from Guantanamo Bay detainees. There is no reason why it could not be used to avoid court review of politically divisive issues ranging from health care to gun control to gay rights, giving enormous power to Congress to sidestep judicial review.

While the current focus is on its use to control a conservative Court if Democrats sweep the 2020 election, it could just as easily be used by Republicans. So why has it not been used more often? Likely because weakening another branch of government would be politically unpopular and hard to explain to an electorate who—like me—believes in the importance of co-equal branches of government.

The 2020 Ig Nobel prize winners, awarded by the Annals of Improbable Research, were announced on September 17th. 2020 marked the thirtieth anniversary for the yearly ceremony, which was held virtually this year.

In this time of great stress, RDM member and CFO Dyanna Ballou takes you through some of the highlights. We hope you get a kick out of this year’s winners, each of whom gets a cash prize of a 10 trillion dollar bill from Zimbabwe.  Stay tuned for Dyanna’s favorite at the end.

And the winners are…

Acoustics: Stephan Reber and his team for inducing a female Chinese alligator to bellow in an airtight chamber filled with helium-enriched air.

Psychology: Miranda Giacomin and Nicholas Rul for developing a method to identify narcissists by examining their eyebrows.

Peace: The governments of India and Pakistan for having their diplomats ring each other’s doorbells in the middle of the night and then run away before anyone had a chance to answer the door. (My girlfriends and I did this in junior high at the houses of cute boys.  That didn’t advance my dating life either.)

Physics: Ivan Maksymov and Andriy Pototsky for determining what happens to the shape of a living earthworm when it is vibrated at high frequency.

Economics: Christopher Watkins and colleagues for quantifying the relationship between different countries’ income inequality and the amount of mouth-to-mouth kissing.

Management: Five professional hitmen in China who contracted to murder each other with none of them actually carrying out the crime.

Entomology: Richard Vetter for collecting evidence that many entomologists (scientists who study insects) are afraid of spiders, which are not insects.

Medical Education: The leaders of Brazil, the United Kingdom, India, Mexico, Belarus, Turkey, Russia and our own U.S. of A for using the Covid-19 pandemic to teach the world that politicians have a more immediate effect on life and death than scientists and doctors.

Materials Science: Metin Eren and his team for showing that knives made from frozen human feces do not work well.

And Dyanna’s personal favorite (“Which I suffer from—just ask my husband!”)

Medicine: Nienke Vulink and team for diagnosing a long-unrecognized medical condition of misophonia, the distress at hearing other people make chewing sounds.

Justice Ruth Bader Ginsburg was given the honor of lying in state in the U.S. Capitol after her death on September 18th. She is the first woman and the first Jew to be given this honor. RDM member and CFO Dyanna Ballou was surprised at that fact, which lead her to research the history of lying in state.

Two types of honors involve the ceremonial presence of remains in the Capitol: “Lay in state” and “lay in honor.” Per the Architect of the Capitol, only government officials or military officers may have their remains lay in state. Private citizens are may have their remains lay in honor.

Henry Clay was the first person to be lain in state in 1852. Since then 34 American officials, judges, and military leaders, have lain in state. U.S. Representative Elijah Cummings was the first Black American given the honor of lying in state in 2019. Only four people have lain in honor, including Rosa Parks.

There are no criteria for who is chosen except Congress’s approval and the deceased family’s consent. Not all those entitled to the honor have it accepted. The families of Presidents Truman and Nixon declined the honor.

Interestingly, those who have lain in state are placed on the catafalque used at President Lincoln’s funeral. Those who have lain in honor are placed on other biers.

Hydrocodone pills and bottles. Hydrocodone is an opioid painkiller.

The ravages of the nation’s opioid crisis are regular topics in the news today. The costs in damaged lives, healthcare expenses, lost productivity, and criminal activity are ever-growing. Now a new avenue for recouping those costs is opening: the plaintiffs’ bar is actively recruiting state and local governments to sue opioid manufacturers to recover the costs of combating the use of opioids. States, cities, and counties are signing up in record numbers, seeking reimbursement for the costs of battling opioid addiction.

The first lawsuit was filed in 2015 by Mississippi’s Attorney General. Now these lawsuits are filed almost weekly. And that certainly will continue, considering the enormous problem of opioid dependency. In 2016, almost 63 million Americans received a prescription for an opioid drug. According to the Centers for Disease Control and Prevention, over 100 Americans die from an opioid overdose every day. We all are familiar with famous names such as Prince, Heath Ledger, and Tom Petty. They represent thousands of other citizens who have had the same sad fate. In addition to death, drug abuse can result in criminal activity and broken lives as addicts who cannot get the painkillers through legal prescriptions turn to illegal drugs such as heroin and the synthetic opioids fentanyl and carfentanil. Synthetic opioids are a frightening development. Fentanyl is 10,000 times stronger than morphine, and carfentanil is 100 times stronger than an equal dose of fentanyl. Misusing these powerful drugs even once can result in death.

We’ve got the experience.

Managing this tidal wave has devastated city, county, and state budgets because of the high costs of police, courts, incarceration, medical care, and addiction treatment. As one example, every day over 1,000 people are treated in emergency rooms for misusing prescription opioids—not to mention the hidden costs of child welfare needs for families torn apart by opioid abuse, babies born to addicted mothers, and even seemingly minor costs such as using city employees to clean up used syringes left in parks. In November 2017, the President’s Council of Economic Advisors calculated the cost of the opioid crisis at $504 billion in 2015 alone. Despite this, when President Donald Trump declared the opioid epidemic a public health emergency in October 2017, neither he nor Congress allocated any extra money to state or local authorities to combat the issue.
