Anheuser-Busch Cos. Inc. is suing Belgian brewer InBev in federal court, seeking to bar its spurned suitor from soliciting support from Anheuser-Busch shareholders.
The lawsuit filed late Monday calls InBev's unsolicited $46 billion offer to buy Anheuser-Busch an illegal scheme.
It says InBev concealed that it does business in Cuba, which could complicate its efforts to operate in the United States.
InBev filed a motion on Monday asking Anheuser-Busch shareholders to fire the company's board of directors and replace those members with a slate selected by InBev.
Anheuser-Busch's lawsuit asks a federal judge to block InBev from making any more solicitations from its shareholders.
