State ex rel. Monsanto Co. v. Honorable Mullen
Annotate this Case
The Supreme Court made permanent a preliminary writ it issued granting Monsanto Company's petition for a writ of prohibition or mandamus requiring the St. Louis circuit court to transfer venue of five of the six plaintiffs' claims, holding that Missouri law compelled this result.
Plaintiffs brought this action claiming that they were injured as a result of exposure to a herbicide manufactured by Monsanto Company and seeking monetary damages. Monsanto filed a motion to transfer venue as to five of the six plaintiffs in this case to St. Louis County but failed to file a motion to transfer in the six plaintiff's case The circuit court subsequently consolidated Plaintiffs' individual claims. Monsanto filed a motion to reconsider, arguing that venue was inappropriate in St. Louis Valley. The circuit court overruled the motion, after which Monsanto sought relief by way of mandamus or prohibition. The Supreme Court granted relief, holding that Mo. Rev. Stat. 508.010.5(1) mandated that venue shall be where Monsanto's registered agent was located as of filing - St. Louis County.
