Talc supplier Barretts Minerals is challenging an effort by creditors, including tort claimants, to move its chapter 11 bankruptcy case from Texas to Montana, where the business has been headquartered.

Facing hundreds of personal injury lawsuits, the former Pfizer minerals business filed for bankruptcy protection in October in the U.S. Bankruptcy Court in Houston. Barretts supplied talc for cosmetic products alleged to have caused injuries primarily from exposure to asbestos supposedly contained in the products.
