Homeland Security Secretary Michael Chertoff has used authority given to him by Congress in 2005 to ignore environmental and other laws and regulations to move forward with hundreds of miles of fencing in Arizona, California, New Mexico and Texas.

The case rejected by the court involved a two-mile section of fence in the San Pedro Riparian National Conservation Area near Naco, Ariz. The section has since been built.

"I am extremely disappointed in the court's decision," Rep. Bennie Thompson, D-Miss., said. "This waiver will only prolong the department from addressing the real issue: their lack of a comprehensive border security plan."

Thompson chairs the House Homeland Security Committee. He and 13 other House democrats — including six other committee chairs — filed a brief in support of the environmentalists' appeal.

Earlier this year, Chertoff waived more than 30 laws and regulations in an effort to finish building 670 miles of fence along the southwest border. Administration officials have said that invoking the legal waivers — which Congress authorized in 1996 and 2005 laws — will cut through bureaucratic red tape and sidestep environmental laws that currently stand in the way of fence construction.

A former partner in Milberg Weiss has sued four of its founding partners - Melvyn Weiss, David Bershad, Steven Schulman, and William Lerach - claiming they lied to him and other attorneys about their secret kickbacks to plaintiffs in shareholder class actions. Michael Buchman sued his former partners in Federal Court on Tuesday, as the firm, now known as Milberg, agreed to pay $75 million to the United States to settle criminal complaints in the scheme.

Buchman says he joined Milberg Weiss Bershad Hynes & Lerach in January 1997 and was made a partner in December 2000. He worked in the antitrust division until he left the firm in February 2007. When Lerach left to set up his own office in 2004, the firm changed its name to Milberg Weiss Bershad & Schulman.

Buchman says the defendants lied to him, and to other attorneys, after federal prosecutors unsealed an indictment in which Seymour Lazar and Paul Selzer alleged that "certain partners of Milberg Weiss" had secretly paid them kickbacks to serve as plaintiffs in securities class actions.

Buchman's complaint states: "In various meetings that occurred at Milberg Weiss after the Lazar Indictment, Defendants Weiss, Bershad and Schulman, who were united in interest, repeatedly represented to plaintiff and to other partners in Milberg Weiss hat the accusations contained in the Lazar Indictment were untrue, politically motivated, and that the government's case rested on mischaracterization of legitimate referral fees paid to other law firms, which assertedly had been duly reported to the government of Forms 1099. Weiss, for example, vigorously denied that the alleged payments had been made to Lazar, and represented that Lazar's sold motivation for pursuing multiple class actions had been to recover for his own injuries and to serve as 'a crusader.'

"Believing these representations of fact by defendants, plaintiff continued to serve as a partner in Milberg Weiss. Similarly, most other Milberg Weiss partners who had no prior knowledge of defendants' unlawful and unethical acts also continued throughout the rest of 2005 to serve as Milberg Weiss partners.

"Defendants had a fiduciary duty to plaintiff and to other Milberg Weiss partners to be honest and forthcoming with government authorities. Were the allegations made in the Lazar Indictment true, defendants had a duty truthfully to reveal their unethical and unlawful conduct to the authorities and to take personal responsibility for such conduct. Instead, defendants refused to acknowledge the truth and continued to misrepresent the facts to government authorities, thereby putting Milberg Weiss as a firm, and the financial and professional interests of plaintiff and other innocent Milberg Weiss partners, in grave jeopardy."
