Lawyers are gearing up to flood the courts with thousands more lawsuits after a jury last week awarded more than $289 million to a former groundskeeper who said he got cancer from Monsanto’s weed killer.

So far, more than 4,000 people have sued over Roundup, most in Missouri and California state courts. About 470 cases have been coordinated in California federal court as multidistrict litigation. Friday’s verdict came in a case that was a bit of an outlier: The plaintiff, Dewayne “Lee” Johnson, went to trial first in San Francisco Superior Court because of his poor health prognosis.
