The US Supreme Court on Thursday ruled to rein in lawsuits alleging that Germany-based agrochemical manufacturer Bayer failed to warn users of the cancer risks posed by the company's Roundup weedkiller.

What are the details of the Supreme Court ruling on Roundup?

The conservative-majority US top court, in a 7-2 decision, overturned a verdict in Missouri which awarded $1.25 million (€1.1 million) to a man named John Durnell.

Durnell had argued that years of Roundup weedkiller use had caused his blood cancer diagnosis.

Durnell's case referred to the International Agency for Research on Cancer's classification that glyphosate, a key ingredient in Roundup, is a probably human carcinogen. The International Agency for Research on Cancer is a part of World Health Organization of the United Nations.
