A deadlocked U.S. Supreme Court upheld a lower court decision against Pfizer Inc's Warner-Lambert unit over withdrawn diabetes drug Rezulin in a ruling announced on Monday, allowing the case to go forward.

By a 4-to-4 vote, the court affirmed a federal appeals court ruling that reinstated the lawsuit against the world's biggest drugmaker by Michigan residents who said their injuries were caused by the diabetes drug.

The split occurred because the court's ninth member, Chief Justice John Roberts, took no part in the case because he owns Pfizer shares. The court's one-sentence ruling does not address the merits of the dispute.

Rezulin, first approved in 1996, was pulled from the market in 2000 after about 100 people who took the medicine needed liver transplants or died. Pfizer has fought thousands of lawsuits claiming the drugmaker failed to warn the public about the drug's toxic effects.

The high court's action clears the way for the case to proceed in federal court in New York.

At issue in the Supreme Court case was a Michigan state law that provides pharmaceutical companies immunity from such suits except when it can be proven that the manufacturer defrauded the U.S. Food and Drug Administration.

Gay rights advocates sued to overturn the ban four years ago after the court halted a monthslong same-sex wedding spree that saw thousands of couples marry at City Hall.

The justices were scheduled to hear three hours of arguments in six cases.

"I think I speak for everybody when I say that this has been a long time coming and a day that has been eagerly anticipated," said City Attorney Dennis Herrera, who is representing the city in a lawsuit supporting gay marriage.

The cases were filed after the court stopped the same-sex marriages in the winter of 2004. More than 4,000 couples exchanged vows at the direction of Mayor Gavin Newsom months before gay marriage became legal in Massachusetts, although the high court ultimately voided the unions.

In briefs submitted to the court, same-sex marriage supporters argued that California's Constitution leaves no room for denying gays and lesbians the right to wed.

They say that while the state is one of a handful where gay couples are entitled to most of the same legal rights as married spouses, the institution of marriage is too important to allow for alternatives that are by definition inferior.

"We're very hopeful that California history will stay true today and we'll see the constitution vindicated for the thousands of families in California who depend on our equal place under law," said Jennifer Pizer, a lawyer with the Lambda Legal Defense and Education Fund who is representing gay couples.

The state and same-sex marriage opponents, however, maintain that limiting marriage to members of the opposite sex is reasonable — not only to uphold tradition but because California voters approved a ballot initiative eight years ago bolstering the gay-marriage ban that was in place at the time. To overturn that law, they say, would abrogate the rights of all Californians.

Jim Clark, who was the former governor's chief of staff, agreed to plead guilty to a single count of conspiracy fraud in a filing in U.S. District Court in Anchorage. He was scheduled to enter his plea at an arraignment hearing on Tuesday.

Clark admitted to taking $68,550 in illegal contributions from the state's largest oil-services company, VECO Corp, for Murkowski's failed 2006 reelection bid in exchange for working on VECO's behalf to secure an industry-friendly version of tax legislation, according to the plea agreement.

He is the first official from the Murkowski administration to be charged in a federal criminal investigation that has so far resulted in convictions of three former state lawmakers, the indictment of a fourth and guilty pleas from two top VECO executives and one former lobbyist.

Murkowski, who was also a former U.S. senator, was soundly defeated in the 2006 Republican primary by Sarah Palin, Alaska's current governor who ran as an anti-corruption reformer.

Clark and VECO conspired to hide the illegal contributions "in a manner so that the public would be deceived and the payments would not be disclosed, as required by law," according to charging documents.

The federal investigation centers around a revision of an oil-tax law that passed the state legislature in 2006 at Murkowski's urging. Bill Allen and Rick Smith, two former VECO executives, pleaded guilty to bribing state lawmakers for a pro-industry version of the bill and other favorable actions.

Former state Senate President Ben Stevens, son of powerful U.S. Senator Ted Stevens, received much of that bribe money, Allen and Smith testified in court last year.

The name of the Bryan Cave law firm has come up in pretrial legal battles in the criminal case against politically connected entrepreneur Antoin "Tony" Rezko.

In a footnote to a motion last week seeking to exclude some government evidence against Rezko, his defense lawyers disclosed for first time that prosecutors have alleged that Rezko paid a $1.5 million bribe to Iraq's former electricity minister to obtain a contract in that country. The alleged bribe was paid from an escrow account held by Bryan Cave, prosecutors said.

Rezko's lawyers said that every aspect of the bribe claim is "demonstrably false."

The bribe allegation is unrelated to the federal influence-peddling and fraud charges against Rezko, whose trial began Monday with jury selection. Its disclosure shows the scope of Rezko's relationship with lawyers who have represented his real estate and restaurant businesses in civil matters.

Another law firm, Freeborn & Peters, was identified by prosecutors last month for its involvement in a $3.5 million overseas wire transfer to Rezko and his associates. The government did not suggest anything illegal on the law firm's part, but evidence of the wire transfer led a federal judge to revoke Rezko's bail in January.

Another one of Rezko's lawyers, Gene Murphy, was a partner in Bryan Cave's Chicago office from April 2004 to August 2005. When Murphy left Bryan Cave, the firm stopped representing Rezko, said Jeffrey Morof, the head of Bryan Cave's Chicago office.

Murphy, who has started his own law firm, said the claim that an alleged bribe came from a Bryan Cave account is "absolutely baseless." He declined further comment on Rezko, other than adding that he no longer represents him.

Morof also denied that the firm had any involvement in an alleged transfer of funds to the former electricity minister.

The bribe allegation came up in a private hearing held in the judge's chambers, according to Rezko's lawyers. A spokesman for the U.S. attorney's office declined to comment.

Blogger unmasked: A vocal critic of some patent lawsuits who blogged anonymously under the pseudonym "Patent Troll Tracker" has revealed himself after being pressured by one of his frequent targets. The blogger is Rick Frenkel, an intellectual-property lawyer at Cisco Systems.

He recently disclosed on his blog that he faced an e-mail threat of being named. In his blog, he tracked lawsuits by companies that acquired patents solely to sue for infringement. Chicago lawyer Raymond Niro represents a number of these entities that have come to be known by the derogatory term of patent trolls.

Niro, tired of being criticized anonymously in the blog, had recently offered a $10,000 bounty for anyone who unmasked the blogger. Niro said no one has stepped forward to claim the reward.

On the move: Assistant U.S. Atty. Daniel Rubinstein has joined Greenberg & Traurig's Chicago office as a shareholder, the firm's equivalent of partner. He worked in the U.S. attorney's office in Chicago for four years, primarily in the complex fraud section. ... Sonnenschein Nath & Rosenthal hired Brian Lambert as its chief marketing officer. He most recently was at Wachovia Corp., where he was head of business development in the treasury services division. ... Jennifer Nijman, a former president of the Chicago Bar Association, has left Winston & Strawn to start her own firm with Susan Franzetti, a solo practitioner who previously worked at Sonnenschein. Their practice will focus on representing businesses in environmental matters.

When Esther Elizabeth Reed was indicted last year, Brooke Henson's relatives said they hoped Reed could tell authorities where to find her.

"Of course at first, it was just giving us hope that Brooke was alive," Lisa Henson, Brooke's aunt, said Monday.

Investigators have since said they don't think Reed had anything to do with Henson's 1999 disappearance.

Reed is accused of stealing Henson's identity in 2003 and posing as her to obtain false identification documents, take a high school equivalency test and get into Columbia University.

She was indicted last year and made her first court appearance Monday on federal charges of identity theft, mail and wire fraud and obtaining false identification documents. If convicted on all four charges, Reed faces a possible $1 million fine and 47 years in prison, time Lisa Henson said she hopes Reed will serve.

"I just hope that she never gets to see the light of day again," she said.

Reed answered routine questions from U.S. Magistrate Judge William M. Catoe and showed no emotion during the brief proceedings. Catoe entered a not guilty plea to all charges.

Reed, who was arrested Feb. 3 outside Chicago, is 29; Brooke Henson would be 29 in April.

Reed began posing as Henson in October 2003, obtaining an ID card in Ohio using her name, date of birth and Social Security number, Assistant U.S. Attorney Walt Wilkins said.

Two months later, Reed took a high school equivalency test in Ohio using Henson's name and received a degree, Wilkins said. Again using Henson's information, she took a college entrance exam in California in May 2004, using her score to apply for admission to Columbia, the prosecutor said.

Reed attended the New York school for two years, beginning in August 2004, Wilkins said. She then applied for and received student loans in Henson's name, in amounts investigators have said exceeded $100,000.

Reed then applied to the state of South Carolina for a duplicate copy of Henson's birth certificate, which she received at an address in Massachusetts. In 2006, Reed also applied for a U.S. passport in Henson's name, Wilkins said.

Investigators have said Reed stole multiple people's identities and also was admitted to Harvard and California State University, Fullerton, though she has not been charged in those cases and Wilkins did not discuss them Monday.

Assistant Federal Defender Lora Collins, who was appointed Monday to represent Reed but did not appear with her in court, did not immediately return a message seeking comment.

A message left at Columbia University's public affairs office after business hours Monday was not immediately returned.

The 2nd U.S. Circuit Court of Appeals in New York last year upheld their convictions on charges of securities fraud, conspiracy to commit bank fraud and bank fraud.

Lawyers for the two men argued that fraud charges should be thrown out because accounting terms were not explained to the jury and because the Rigases properly followed accounting rules during transactions that the government said were fraudulent.

Federal investigators began looking at Adelphia after it said in a footnote to a press release in 2002 that the company had approximately $2.2 billion in liabilities not previously reported on its balance sheet.

At trial, prosecutors said the Rigas family used the business for personal expenses, withdrawing millions of dollars to finance everything from 100 pairs of bedroom slippers for Timothy Rigas to more than $3 million to produce a film by John Rigas' daughter, Ellen, to $26 million on 3,600 acres of timberland to preserve the view outside the father's home.

Prosecutors said John Rigas once even spent $6,000 to fly two Christmas trees to New York for his daughter.

Last year, another son, Michael Rigas, was sentenced to 10 months home confinement after pleading guilty to a charge of making a false entry in a company record.

John Rigas, the son of Greek immigrants, created Adelphia from nothing when he bought the rights to wire the town of Coudersport, Pa., for cable television in 1952.

The problems arose after he took Adelphia public in 1986 and the company grew rapidly in the late 1990s.

Adelphia served more than 5 million customers in 31 states. It collapsed into bankruptcy in 2002.

It moved to Greenwood Village, Colo. Comcast Corp. in Philadelphia and Time Warner Cable, a unit of Time Warner Inc., have since bought Adelphia's cable assets.
