Shareholders for Dollar Thrifty Automotive Group have asked a US district court judge to stop the upcoming vote by its board members regarding the takeover bid by Hertz Global Holdings, Inc. Dollar Thrifty, the fourth largest car hire firm in the US, has been the target of a merger by both Hertz and Avis Budget Group Inc, and according to the legal representative for the Dollar Thrifty shareholders, the board at Dollar Thrifty is rushing to vote on the Hertz bid, and has not given the Avis bid enough attention and credibility.

The legal injunction was brought to Delaware Chancery Court Judge Leo Strine at a hearing earlier this week, and according to Judge Strine, he will decide at a later date whether or not the board vote regarding the Hertz bid, scheduled for 16 September, can proceed. The Hertz bid totals $1.1 billion, or $41 per share, while the Avis bid is over $1.3 billion, or $46.50 per share.

The legal representative for the Dollar Thrifty board of directors, Mitchell Lowenthal, said that the attempt to stop the vote is a mistake, as the Hertz offer, although lower, is much more fiscally viable. He went on to add that if the firm decided against Hertz, the penalty of terminating the agreement would cost close to $50 million dollars.
