The pharmaceutical and chemical company Bayer has to accept a setback in the US legal dispute over alleged cancer risks of the glyphosate-containing weed killer Roundup, according to a report by the Bloomberg finance agency.

Judge Vince Chhabria on Wednesday rejected the application of the Leverkusen-based company to provisionally approve a settlement of future disputes against payment of two billion US dollars (a good 1.6 billion euros).

Initially, no comments were received from Bayer.

The proposal is part of a larger settlement related to glyphosate lawsuits.

Judge Chhabria had previously been skeptical of a settlement draft to deal with future glyphosate lawsuits in the United States. The desired compromise for a total of two billion US dollars is now the decisive part of a more extensive settlement with plaintiffs, which would cost Bayer over eleven billion dollars in total, but would draw a line under the legal glyphosate debacle. At the court of the federal judge Chhabria, numerous national proceedings are bundled.
