Judge orders mediation in massive 3M earplug litigation

Star Tribune  print


Court-ordered mediation is standard, but the size and potential impact of the earplug litigation isn't, said Alexandra Lahav, a professor at the University of Connecticut School of Law. "I don't think there has ever been as big an MDL as this one … The judge is saying it would be a lot better for the [judicial] system if the two sides got together and solved this," Lahav said. "She's not threatening them so much as guilting them."

Costs mount for 3M as earplug trials drag on

Star Tribune  print


Without a settlement, thousands more cases will go to trial in what has become the largest U.S. mass tort ever. Two stock analysts recently estimated total payouts to plaintiffs could be around $15 billion. "Right now, it looks like a 50-50 shot the plaintiffs will win," said Alexandra Lahav, a professor at the University of Connecticut School of Law. Their ratio of victories shows "there is merit to their cases. ... The plaintiffs right now have a lot of leverage, and 3M is thinking, how can we turn the tide?"

It has been more common for a judge to issue a directed verdict either before jurors begin deliberations or after they have reached a verdict. "The dispute isn't about what he (Rakoff) is doing," said Alexandra Lahav, a University of Connecticut law professor. "It is that he communicated his thinking at this stage of the case."

How much Texas gets from multistate, $26 billion opioid settlement hinges on how many local governments sign on

KSAT  online


Alexandra Lahav, a law professor at the University of Connecticut, said local officials should consider how much a lawsuit will cost, what their likelihood of success is, how much money they stand to win and how long it would take them to receive that money. Even if a municipality wins at trial, Lahav said, the ruling likely would be appealed, further delaying the payments for tackling the crisis. The settlement Texas worked out on the other hand, could be less money than originally sought, but is guaranteed and could start flowing to their communities faster.

Burned in Tobacco Deal, Cities in Drug Fight Target McKinsey

Bloomberg  online


McKinsey says almost all the states agreed that the deal they signed covers any other claims, setting up a legal fight between the company and local governments pressing ahead with their cases. At the heart of the dispute is who decides the fate of money intended to combat addiction and crime linked to the U.S. opioid crisis that’s killed hundreds of thousands of people. “There’s going to be a lot of litigation,” said Alexandra Lahav, a University of Connecticut law professor who specializes in mass tort cases. “Every state takes its own view of the powers an attorney general has to resolve claims on behalf of local governments within the state’s borders.”

How 3M earplug litigation got to be biggest MDL in history

A related factor is that it is very easy to ascertain who potential plaintiffs are, said Alexandra Lahav of the University of Connecticut Law School. “If you had earplugs and you were in the military, that’s a thing you would know about yourself,” she said. In other mass torts, such as those over the painkiller Vioxx or Bayer’s weedkiller Roundup, people are much less likely to remember whether they used the product, or how much, at some point in the past, she said.

The size of the earplug litigation — nearly 230,000 claims are pending before a federal court in Pensacola, Fla. — dwarfs most mass torts. The case is being closely watched in legal circles. "Anytime you get a case with this many people involved, people turn their heads," said Alexandra Lahav, a professor at the University of Connecticut School of Law. "It's an incredibly large number of complaints."

Bayer wants to resolve future Roundup liability in a class action. A new mass torts paradigm?

So why is the settlement so innovative? It’s true that some of its key elements have featured in previous mass tort deals. A West Virginia class action alleging that Dupont contaminated drinking water with toxic chemicals relied on a panel of scientific experts to determine threshold causation, as University of Connecticut professor Alexandra Lahav discussed in a just-published study cited in plaintiffs’ motion for preliminary approval. And some huge recent mass tort settlements, such as the BP Deepwater Horizon oil spill case and the NFL concussion litigation, have used the class action vehicle to resolve claims, including, in the NFL case, future claims by plaintiffs whose injuries have not yet manifested.

Major drugstore chains sue doctors in sprawling federal opioid case

Washington Post  print


Alexandra Lahav, a professor at the University of Connecticut School of Law who also follows the case, said the companies may be signaling to Polster that if pharmacists are going to be held responsible for their dispensing activity, they will want to examine the prescribing habits of doctors across the two counties — a seemingly huge task. “This is an illustration of how complex and maybe impossible it may be to prove the underlying claim that Cuyahoga County is trying to prove against these drugstores,” she said. “Are we going to question every time we dispensed a drug over a 20-year period?”

Cuyahoga And Summit Zero In On Next Opioid Defendants: Pharmacies

WKSU - NPR  radio


Meanwhile, it’s still unclear whether states, counties and drug companies can agree to a universal settlement that would lay to rest all of the lawsuits over the opioid crisis. The Sixth U.S. Circuit Court of Appeals has said it will review a proposal to include all cities and counties in the country in a special class that could vote on potential settlements. State attorneys general have opposed the novel plan. “It’s never been tried before, and it would have given them some pretty big leverage to settle with the defendants,” University of Connecticut law professor Alexandra Lahav said, “because they could promise the defendants that everyone was included.”

High-profile trial over who should pay for the opioid crisis begins

Washington Post  print


Described as the most complex litigation ever, the trial will begin to sort out the welter of accusations over the crisis. While six drug companies are defendants in the case, jurors also may hear blame cast widely on doctors, government agencies and perhaps even drug users themselves. The jury’s response will help decide who should bear the cost of one of this century’s worst public health crises. “What’s pushing them to trial is the attempt to reach a settlement in a vacuum and the difficulty of doing that,” said Alexandra Lahav, a professor at the University of Connecticut School of Law who studies mass tort cases like this one.

Bayer could benefit from home advantage in St. Louis Roundup cancer trial: experts

By suing in the county where Bayer’s crop science business is headquartered, plaintiffs can also take advantage of procedural rules allowing them to compel live testimony from executives who work locally. In the California trials, jurors only saw video depositions of Monsanto executives. But Alexandra Lahav, a law professor at the University of Connecticut, said Bayer could simply be using new experts that the company thinks would have a better rapport with the jury and “not necessarily because the experts are local.”

“Public nuisance claims are somewhat adventuresome,” notes Alexandra Lahav of the University of Connecticut School of Law. “It’s not an area that has been well litigated. So whenever you have a public nuisance claim, you are always striking new ground. That’s more opportunity, but it also means it’s hard to predict for us looking from the outside what this judge is going to do.”

Monsanto Roundup appeal has uphill climb on 'junk science' grounds: legal experts

Bayer AG unit Monsanto faces long odds on an appeal blaming an “inflamed” jury and “junk science” for a verdict of $289 million in damages to a man who said the company’s Roundup weed killer caused his cancer, according to some legal experts. Monsanto said the plaintiff’s experts should have been excluded because although they mainly cited respected, peer-reviewed studies, they inappropriately cherry-picked results and used unreliable methods to support the position that glysophate causes cancer in humans. But Alexandra Lahav, a law professor at the University of Connecticut, said it was common for experts to rely on the same studies and reach different conclusions to present to a jury during trial.

Hillary Clinton says Bernie Sanders wants higher standards for toy guns than real guns

"A hypothetical situation might be if a city experienced an epidemic of deaths or injuries that resulted from a prevalence of realistic-looking toy guns; think of the recent story of Tamir Rice, a Cleveland child carrying a toy gun who a police officer shot and killed, said Alexandra Lahav, a professor of civil procedure at the University of Connecticut School of Law. In that case, a city might want to bring a suit against the toy gun manufacturer or seller for creating a public nuisance. But under the 2005 law, a city cannot sue a gun company if there is an epidemic of people being injured or killed by their guns."

ACLU family separation case highlights alternate path for Trump challengers

Reuters  print


Law professor Alexandra Lahav of the University of Connecticut, a class action procedure expert, told me that civil rights advocates have been relied on sweeping class action injunctions to challenge state and federal policies since before the modern federal rules of procedure for class actions were adopted in 1966. In fact, according to a post Lahav and three other law profs wrote for the Harvard Law Review last month, the class action rules were drafted with these cases in mind, “to address precisely the scenario where a government policy systematically denies a group of plaintiffs a meaningful opportunity to vindicate their rights.” Due process challenges against government agencies – exactly like the ACLU’s family separation case – have been considered particularly appropriate for sweeping class action treatment, the profs wrote, because “they often raise generic questions about how uniform hearing procedures impact a group of people who depend on them for relief.”

Similarly, there are two dominant views of the class action lawyer ...
