On March 25, 2019, Judge Gary L. Sharpe of the Northern District of New York dismissed a putative class action against CVS and Lang Pharma alleging that the labeling of defendants’ CVS Omega-3 Krill Oil is deceptive and misleading.  Plaintiff in the lawsuit, James Gaminde, alleged that CVS Omega-3 Krill Oil contained only sixty percent of the 300mg of Omega-3 Krill Oil represented by the label, and therefore violated New York’s General Business Law sections…
As you all know, the Northern District of California jury found earlier this week that Monsanto’s Roundup herbicide product was a “substantial factor” in causing a plaintiff’s non Hodgkin lymphoma. The defendants and industry were all very optimistic that the trial, which focused solely on causation and not knowledge or company conduct, would result in an impartial scientific analysis. Unfortunately, the jury ignored a very substantial body of literature that glyphosate, the active ingredient in…
Mortgage service companies (and their lawyers) got a big boost on March 20, 2019, when the Supreme Court delivered a unanimous opinion in Obduskey v. McCarthy & Holthus LLP, holding that a business engaged in no more than nonjudicial foreclosure proceedings is not a “debt collector” under the Fair Debt Collection Practices Act (FDCPA or Act), except for the limited purpose of §1692f(6). This decision will prevent needless and unfair litigation by borrowers seeking to…

Last week, the California Court of Appeal held that a plaintiff’s suit seeking to require Proposition 65 acrylamide based cancer warnings on 59 popular breakfast cereals was pre-empted by federal nutrition policies aimed at encouraging Americans to consume more whole grains and by FDA letters stating that any warnings should be deferred given the uncertain science on the risks to humans of acrylamide in food. This conflict pre-emption ruling should help convince courts in other…

The report has already received…
