Court records show a former government scientist accused of attempted espionage last week pleaded guilty earlier this year to overbilling NASA and the Department of Defense more than $265,000 for contracting work.

The January plea by 52-year-old Stewart Nozette of Chevy Chase, Md., was detailed in court records unsealed Friday. The records state the documents were sealed because Nozette was cooperating in unrelated government corruption investigations.

Nozette was arrested last week and accused of selling sensitive government secrets to an FBI agent posing as an Israeli intelligence operative.

The unsealed court documents say Nozette pleaded guilty in January to overbilling the government between 2000 and 2006 and spending the money on personal bills and maintaining his swimming pool.

Two U.S. Supreme Court justices are taking theatrics out of the courtroom — and into to a more suitable venue.

Justices Ruth Bader Ginsburg and Antonin Scalia will have nonspeaking roles Saturday night in a production by the Washington National Opera. They'll be dressed in black-tie attire and remain on stage for nearly 90 minutes during the opening performance of "Ariadne auf Naxos" (are-EE-AHD-nay off NACKS-ohs).

The opera depicts a serious opera company and a comedic troupe performing at the same time during a dinner party. The justices will play party guests.

Event organizers say Ginsburg and Scalia are opera lovers and have appeared in previous productions.

More than 6,000 people crowded outside a Tokyo courthouse Monday as Japanese actress Noriko Sakai pleaded guilty to drug use and prosecutors sought a prison sentence in a trial that has caused a media frenzy.

The 38-year-old Sakai was among the first Japanese actresses to gain popularity in Asia, and her arrest in August threatened to shatter her wholesome image.

The scandal has dominated headlines for months in Japan, and authorities have said they will crack down on drug use in the entertainment industry.

Prosecutors accused Sakai of inhaling amphetamines in July on the southern island of Amami Oshima, where she went with her husband and their son to view a lunar eclipse. Investigators also found a tiny amount of the drug in her Tokyo condominium. Sakai was arrested after turning herself in, following a weeklong disappearance.

In Minnesota, bong water can count as an illegal drug.

That decision from Minnesota's Supreme Court on Thursday raises the threat of longer sentences for drug smokers in that state who fail to dump the water out of bong — a type of water pipe often used to smoke drugs

The court said a person can be prosecuted for a first-degree drug crime for 25 grams or more of bong water that tests positive for a controlled substance.

Lower courts had held that bong water is drug paraphernalia. Possession of that is a misdemeanor crime.

The case involved a woman whose bong had about 2 1/2 tablespoons of liquid that tested positive for methamphetamine. A narcotics officer had testified that drug users sometimes keep bong water to drink or inject later.

The Kentucky Supreme Court is deciding whether the state has the power to seize Internet domain names involved in online gambling after hearing arguments Thursday from lawyers on both sides of the issue.

At issue is whether the more than 100 domain names the state has tried to seize are tantamount to gambling devices such as slot machines, and whether the state has authority for the seizures.

An appellate court has previously ruled that the state can't seize the domain names.

"They have been using these to violate the law in Kentucky," Eric Lycan, a private attorney representing the Kentucky Justice Cabinet, said. "They are subject to forfeiture."

The state previously sued 140 Web sites after determining that they allowed Kentuckians to gamble illegally and asked a judge to either force the sites to block Kentucky users or allow the state to take possession of the domain names — essentially shutting them down. Most of the sites are offshore and serve gamblers in and outside of the state.

Kentucky already allows gambling on horse racing and bingo and has a state lottery.

The Arkansas Supreme Court said Thursday it will review a case involving Southwestern Electric Power Company's planned coal-fired power plant in south Arkansas.

The state Court of Appeals had overturned a permit that was issued by the Arkansas Public Service Commission for the $1.6 billion John W. Turk Jr. plant in Hempstead County. SWEPCO appealed that decision, and now the Arkansas Supreme Court is going to review the case.

The Appeals Court ruling, issued in June, said the Public Service Commission's process for considering such permits has been flawed. If upheld, the ruling would require the plant to start that process over.

SWEPCO said Thursday it was pleased the high court was to review the case.

"This is an important case — both for the Turk Plant and for the process used to approve major utility projects in Arkansas for more than 30 years," said Paul Chodak, SWEPCO's president and chief operating officer. "We believe the record in the case will show that the approval process was correct and that the Turk Plant approval should stand."

SWEPCO said that as of Sept. 30, about $830 million had been spent on the Turk project.

Opponents have argued that the plant would violate the federal Clean Air Act.
