Dayton Hudson Corp., the nation's sixth-largest retailer, has won substantial support from the Minnesota state legislature to help the company thwart a possible takeover bid by Washington's Haft family.

Amid speculation on Wall Street that the Hafts may have sold their stake in Dayton Hudson, committees in both the state Senate and House approved legislation yesterday to make it more difficult for Dart or other companies to take over any Minnesota company. Minnesota Gov. Rudy Perpich last night called for an emergency session of the state legislature this afternoon to consider the measure.

The Hafts, through a spokesman, declined to comment on whether they had sold their shares in Dayton Hudson. A Wall Street source yesterday said "the general feeling is they sold their shares."

Dayton Hudson stock dropped sharply yesterday, closing at $51 on the New York Stock Exchange, down $2.12 1/2 from Tuesday. The stock rose sharply on Tuesday and then fell later in the day in response to reports that a Cincinnati investor was planning a $70-a-share takeover bid that later proved to be a hoax.

Some traders said Dayton Hudson stock fell yesterday in reaction to the rumors that the Hafts may have sold their shares, while other financial analysts said the drop was caused by the expectation that Minnesota would pass an antitakeover law by the end of this week.

It is unclear how many shares the Hafts, through their Landover company Dart Group Corp., had purchased in Dayton Hudson. They have declined to comment, but last week Dayton Hudson Chairman Kenneth A. Macke said the Hafts were interested in buying the company and had acquired a "substantial" holding in the firm.

If Dart had purchased 5 percent or more of the stock, it would have had to file a notice with the Securities and Exchange Commission 10 days after it reached the 5 percent level.

"Last week we were contacted by {the} Haft family who said they wanted to acquire our company," Macke testified before state senate hearings on the proposed takeover legislation.

"We said we were not interested. They countered that they remain interested," he added.

Within the past three weeks, Macke said, about 35 million shares -- or 35 percent of the company's outstanding stock -- have changed hands.

Dayton Hudson has urged the state legislature to enact legislation that would, among other things, bar an acquiring company from selling off any corporate assets to finance the takeover for at least five years after the takeover. The law would apply to all Minnesota firms. Additionally, the acquiring company and the corporation's management would be barred from voting their shares on any proposed merger.

Yesterday, such legislation was unanimously approved by both the House Commerce and Judiciary committees, and Senate Commerce and Judiciary committees informally approved a bill. However the House committees added two key amendments that the Senate appeared reluctant to approve. One would ban "golden parachutes" -- the special severance payments that corporate management often sets for itself when it is the target of a takeover bid. Another amendment bans "greenmail" -- a payment the company makes at a premium over market price to buy back the stock from a bidder and get rid of the takeover threat.

"Tomorrow, we'll pass a bill," predicted Senate Majority Leader Roger Moe late yesterday.

Speculation over a takeover for Dayton Hudson took a bizarre twist on Tuesday when a bogus bid for the company was made by a Cincinnati businessman, P. David Herrlinger. He told the Dow Jones News Service that he planned to offer $70 a share for the company with a Cincinnati firm. That bid later turned out to be a hoax, and Herrlinger was hospitalized by his wife.
