Crown Zellerbach returned to court.

The paper and forest products company asked for a federal court order that British financier Sir James Goldsmith give it 48 hours’ notice if he plans to buy additional stock. Goldsmith owns about 8.5% of the company’s stock and had offered $42.50 a share for an additional 19 million of the company’s 27.2 million outstanding shares. He dropped his takeover bid last week, but Crown Zellerbach attorney Gilbert Serota argued before U.S. District Judge Bruce Thompson in Reno, Nev., that Goldsmith may still intend a takeover.
