A judge overstepped his authority when he tried to ban enforcement around the world of an $18 billion judgment against Chevron Inc. for environmental damage in Ecuador, a federal appeals court said Thursday.

The three-judge panel of the 2nd U.S. Circuit Court of Appeals explained why it lifted the ban last year and blocked a judge from staging a trial to decide if the judgment was obtained fairly.

It said the judge has authority to block collection if Ecuadorean plaintiffs move against Chevron in New York, but law does not give him authority "to dictate to the entire world which judgments are entitled to respect and which countries' courts are to be treated as international pariahs."

The judgment came last February after nearly two decades of litigation that stemmed from the poisoning of land in the Ecuadorean rainforest while the oil company Texaco was operating an oil consortium from 1972 to 1990 in the Amazon. Texaco became a wholly owned subsidiary of Chevron in 2001.

Chevron obtained an order from U.S. District Judge Lewis A. Kaplan in March blocking Ecuadorean plaintiffs from trying to collect the $18 billion until he could stage a trial to determine whether the judgment was fraudulently obtained.

The Ecuadorean plaintiffs appealed Kaplan's ruling to the 2nd Circuit. The appeals court heard oral arguments and then issued an order in September lifting Kaplan's block on collection efforts. On Thursday, it went a step further, tossing out the portion of Chevron's challenge to the judgment that sought to block its enforcement anywhere in the world.

Hustler Magazine argued Wednesday in a federal appeals court that its decision to publish nude photos of a model months after she was killed by her wrestler husband was protected by the First Amendment because she was a newsworthy figure.

The family of Nancy Toffolini Benoit has waged a legal battle against the pornographic magazine since it published the photos after she and her son were killed in 2007 by wrestler Chris Benoit. Her family said she never gave the magazine permission to print the photos.

The 11th U.S. Circuit Court of Appeals ruled in June 2009 that a notorious death doesn't give publishers a blank check to publish any images they wish. The case went to trial, and a jury in June 2011 voted to slap Hustler Magazine with $19.6 million in punitive damages for running the photos. A federal judge soon reduced that award to $250,000 to abide by a Georgia law capping damages.

The debate before the court on Wednesday was not only whether to reinstate the jury's eye-popping verdict, but also whether the case should have even gone to trial.

The first was Vermont's campaign finance law setting the lowest contribution limits in the country — shot down by the U.S. Supreme Court.

The same fate befell the state's attempt to restrict drug company efforts to collect data on doctors' prescribing habits. On a 6-3 vote, the justices said Vermont's law was an unconstitutional infringement on free speech by drug and data collecting companies.

Now, in yet another case that has garnered national attention, the office of Vermont Attorney General William Sorrell has suffered a stinging defeat, this time in a federal trial over the state's bid to close the Vermont Yankee nuclear plant.

Some observers are starting to see a pattern — one in which Sorrell and his team have gone to the legal big leagues three times and fallen flat on each attempt.

"The state now has sort of a reputation in the 2nd Circuit and the Supreme Court of not having their act together," said Patrick Parenteau, a former state commissioner of environmental conservation who is now a professor at Vermont Law School.

Gov. Chris Christie moved to diversify the state's all-white Supreme Court on Monday with two firsts: the nominations of an openly gay black man and a Korean-born prosecutor to fill two vacancies.

If confirmed, Bruce A. Harris would become New Jersey's first openly gay justice, and Phillip H. Kwon would become its first Asian representative and the first justice born outside the United States.

Christie, a Republican, said he had "extreme confidence" in the records and intellects of his nominees, neither of whom has been a judge.

"I felt strongly about making sure the court have diversity but first and foremost that the court have quality justices who make sure they take the court in a direction that is a responsible one for the future of our state and its people," Christie said at a news conference attended by the nominees and their families.

Harris, 61, is the Republican mayor of Chatham Borough in Morris County, a post Christie said he would give up if confirmed. He would be the third African-American to be seated on the court.

The U.S. Supreme Court ruled unanimously Monday that police must get a search warrant before using GPS technology to track criminal suspects.

The ruling represents a serious complication for law enforcement nationwide, which increasingly relies on high tech surveillance of suspects, including the use of various types of satellite technology.

A GPS device installed by police on Washington nightclub owner Antoine Jones' Jeep helped them link him to a suburban house used to stash money and drugs. He was sentenced to life in prison before the appeals court overturned the conviction.

Associate Justice Antonin Scalia said that the government's installation of a GPS device, and its use to monitor the vehicle's movements, constitutes a search, meaning that a warrant is required.
