"We find it very disturbing that MillerCoors withheld critical documents that undermine its primary defense in this case, and our legal team will be addressing this matter further," he said in a statement. "We're pleased that the court recognized that MillerCoors violated the discovery rules by withholding unfavorable documents and sanctioned MillerCoors for doing so. We look forward to updating our expert reports with this new discovery material and proving its claims at trial."
