Two days after a federal judge said he was likely to deny approval of Bayer’s $1.1 billion class action settlement over Roundup, the lead plaintiffs attorneys withdrew their court documents in order to revise the agreement.

Plaintiffs attorney Elizabeth Cabraser filed the notice of withdrawal Wednesday. The filing comes after U.S. District Judge Vince Chhabria of the Northern District of California raised several concerns about the settlement, reached last month alongside a raft of other agreements, valued at up to $10.9 billion, which resolved 75% of the 125,000 claims alleging Roundup caused non-Hodgkin lymphoma.
